PRODUCT UPDATE:  Following extensive trials and consultation, Daikin has now approved Reflok’s Mechanical Jointing and Aluminium pipe system for use in the installation of their air conditioning and heating systems.

Daikin’s approval comes following the growing demand for the use of alternative methods of jointing and piping to eliminate the need for of hot works on site, particulary where a customers’ specification can be restrictive with it's use.

Howard Noble, Managing Director of Reflok (Europe) said “This is great news for Reflok who has been approached many times by contractors asking if use of its pipe system would invalidate the Daikin’ warranty terms. On the day Daikin approved the use of alternative pipework a contractor immediately ordered Reflok for an installation.”

In a statement Daikin said they will continue to maintain its manufacturers warranty on air conditioning and heating systems using these alternative methods providing the following criteria are met:

  • Any system piping or jointing materials & methods must meet all local and European legislation, including F-Gas obligations to minimise or eliminate the possibility of refrigerant leaks, and the safety and environmental requirements of BS-EN378.
  • Any damage directly or indirectly caused to the installed Daikin system through installation or use of these methods or materials will not be covered by the Daikin warranty, this includes increased wear and tear on the system caused by a lack of refrigerant.
  • All Refnet joints used on Daikin systems must be original Daikin supplied parts, this is to ensure correct system pressure, oil and gas distribution. The use of third party refnets, Y or T pieces is not supported and could invalidate the warranty.
  • Any materials used should not increase the pressure drop or introduce any foreign substances into the refrigerant circuit when compared to the recommended refrigerant grade copper mentioned in the relevant Daikin installation manuals.
  • Any installation using different pipework materials (i.e. Copper to Aluminum) must use a system that prevents any dielectric / bi-metal / galvanic corrosion from occurring through the operational life of the system including maintenance and service activities.

Reflok has a range of fittings that allow direct connection to Daikin’s Refnets allowing a true ‘heat free’ installation.

Reflok is also available from international stockists. To find a distributor near you visit

UK:  Cool-Therm, the expanding chiller and air conditioning specialist, has opened a new South of England office to serve the expanding London, South East and Home Counties market.

Headed by Steve Soffe, Southern region manager, the new branch is located at East Malling Business Centre. The Bristol headquartered company now operates five branches across the UK, the other outlets being in Cardiff, Reading, Birmingham and Manchester.

The new branch has got off to a flying start, recently securing in excess of £1.5m worth of chiller orders.

This includes orders for nine Turbomiser chillers for a data centre, three Turbomisers for a commercial building, two bespoke ultra low-noise chillers for a multi-storey residential development, and a chiller for a replacement project at a Hilton Hotel in central London.

Ken Strong, managing director of Cool-Therm, says: “London and some surrounding areas are undergoing something of a mini-boom, with significant opportunities for both new and replacement air conditioning projects. Our new office is ideally located to serve our expanding customer base in the region.

“Multi-storey developments planned for the former industrial areas alongside the Thames are particularly exciting, as they include both high-end residential apartments and associated retail and leisure developments, all requiring air conditioning. Given sensitivity to noise for such inner city projects, our proven low noise, low energy Turbomiser is an extremely attractive solution.”

The company has recently developed an ultra-low noise version of its already-quiet Turbomiser, capable of operating down to 51dBA at 10m, making it one of the quietest chillers in the world.

It features Cool-Therm’s new Hush-Tec technology, which uses noise attenuating towers positioned over each condenser fan, lead-insulated refrigerant discharge lines, and full acoustic encapsulation of compressors.

Ken Strong says: “The sound of birds singing in a field in the countryside is can be louder than the new Hush-Tec equipped Turbomisers. This is quite an achievement, and lends itself perfectly to inner city high-end residential apartments and office developments where noise is a critical factor.”

Cool-Therm’s new Southern office can be contacted on 07510 323148, 01732 321885, email

UK:  Leading temporary cooling and heating specialist, Carrier Rental Systems has secured a contract to supply temporary cooling, heating and ventilation for a high profile film studio project.

A major production company has converted a factory building in London into individual sections to create a film set along with workshops, dressing rooms and a technical centre. Each of the six separate spaces required its own heating, ventilating and air conditioning (HVAC) services to maintain optimum conditions for film crews, performers and technical equipment.

“Because of the age of the building, there was no existing HVAC infrastructure,” said Simon Ward, national events manager, Carrier Rental Systems. “The client asked us to equip the site with high-efficiency temporary HVAC services so it can operate to full, modern standards during the 39-week film production period.”

Carrier Rental Systems supplied rooftop-mounted chillers and indirect fired units for space heating and a 100kW boiler to supply hot water to air handling units. The company, which also installed and commissioned the plant, supplied the building with a number of portable heaters to provide comfort in specific areas.

Due to the importance of maintaining a clean, dust-free atmosphere during construction, porous fabric ducting was used to supply low velocity air in order to avoid entrainment of fine air-borne particles.

Carrier Rental Systems’ solution included a remote control system enabling crew to switch the plant on and off when the stage set is being used. When turned on again after a take, the supply of cool air is instantly restored without noise or vibration affecting production.

USA:  Honeywell's new Solstice refrigerant for supermarket refrigeration has been named a finalist for the R&D 100 Awards, sponsored by R&D Magazine.

Often referred to as the "Oscars of Invention," the R&D 100 Awards honors the 100 most innovative technologies and services of the past year. Evaluated with Oak Ridge National Laboratory, Solstice N40 (R-448A) refrigerant replaces high-global-warming refrigerants in supermarket applications. It is part of a growing line of Solstice products for applications ranging from auto air conditioning to highly-energy efficient appliance and building insulation, that have significantly lower global warming potential.

"Naming Solstice N40 a finalist for this award recognizes more than a decade of research and investment that resulted in new solutions to help end customers lower their greenhouse gas impact while complying with new and anticipated regulations," said George Koutsaftes, refrigerants business director for Honeywell Fluorine Products. "In addition to its lower environmental impact, Solstice N40 is highly energy efficient, giving supermarket owners an added benefit."

"This was a particularly strong year for research and development, led by many outstanding technologies that broadened the scope of innovation," said R&D Magazine Editor Lindsay Hock. "We are honored to recognize these products and the project teams behind the design, development, testing, and production of these remarkable innovations and their impact in the field."

Solstice N40 refrigerant, also known as R-448A, has a global warming potential (GWP) that is 68 percent lower than R-404A. In supermarket trials conducted in the U.S. and Europe, Solstice N40 demonstrated at least 3 percent lower energy consumption in low-temperature applications and 5 to 16 percent lower energy consumption in medium-temperature refrigeration compared with R-404A. In R-22 retrofit scenarios, Solstice N40 delivers similar system performance. Whether replacing R-22 or R-404A, Solstice N40 is a near drop-in replacement for supermarkets. Solstice N40 is nonflammable (ASHRAE A1) and non-ozone-depleting.

Global regulators are increasingly moving to phase out high-global-warming refrigerants and, on July 20, the U.S. Environmental Protection Agency published landmark regulations that will phase out the use of many hydrofluorocarbon (HFC) refrigerants. The new regulation, effective July 2016, will require supermarkets, largest consumers of the HFC refrigerant R-404A in the U.S., to discontinue its use as a retrofit refrigerant. R-404A will also not be permitted for use in new supermarkets beginning January 1, 2017.

Solstice N40 was nominated by the publication in the Mechanical Devices/Materials category.

The winners will be announced at a Gala Dinner at Caesars Palace, Las Vegas on November 13.

UK:  The innovative approach of UK contractors, designers and end users is helping push forward the boundaries of refrigeration and drive technical advances globally, according to Bitzer UK managing director Kevin Glass.

Marking the launch of Bitzer UK’s new programme of training courses, Kevin paid tribute to the ingenuity and vision of the UK industry and its customers, which he believes is making an important contribution to the international effort to develop safer, more environmentally acceptable systems.

Bitzer UK managing director Kevin GlassKevin Glass said: “The UK is known to be pretty technically advanced, driven in part by the leading end users. But it is not often appreciated how big an impact this has on the wider global refrigeration scene.

“Bitzer as a group has a worldwide perspective, and Britain is known for its willingness to challenge accepted ways of doing things, which puts our industry at the forefront of many exciting new approaches, particularly in relation to environmental issues.”

End users’ focus on reducing running costs and improving environmental credentials was a key driver, he said. “Almost every day, we are involved in conversations about new ways to solve problems. With such a large product range and extensive application knowledge, we are often able to develop novel solutions to meet unusual, specific or challenging requirements.”

On the legislative front, Kevin believes the implications of the revised F-Gas Regulation will be felt across the industry for years to come.  He said: “There are two distinct approaches evident in the industry to the latest F-Gas changes. People are either choosing to ignore them for the present and continuing to use R404A for all applications. Or they are putting in place plans to exit R404A, and replace it with a lower GWP, natural, or HFO alternative.”

He added: “The truth is, there is no silver bullet for all applications. But one thing is certain: in the low GWP future ahead, the industry will have to learn to manage such things as flammability, toxicity and temperature glide.”

Bitzer has been working for some time with the foresight of a worst-case scenario. The result is a range of proven options that cater for all eventualities, including solutions based on natural refrigerants such ammonia, CO2 and hydrocarbons, as well as low GWP alternatives using HFO and other refrigerants.

Kevin Glass added “The UK is a key market for Bitzer, which is why we have put in place new distribution arrangements and continue to invest in training to support our suppliers and growing customer base. In terms of innovation, the UK is technically exciting and creative, with new ideas and approaches being developed that have potential for global application.

“We believe the UK will always generate new ideas and push boundaries, and – as we have done for many decades already - Bitzer UK will be here to support the pioneers helping to shape the industry’s future.”

UK:  Toshiba is all set to raise the bar with the launch of its new groundbreaking energy efficient SMMS-e VRF air conditioning heat pump system.

The latest generation of the company’s industry-leading VRF continues to push the boundaries, by setting a new benchmark for energy efficiency and comes fully loaded with a number of industry firsts such as continuous heating and an innovative hands-free wireless commissioning system.


Toshiba’s SMMS-e VRF air conditioning heat pump rotary compressor

At the heart of Toshiba’s new technology is a new rotary compressor, which uses a two-stage compression process for improved efficiency and performance.

Surfaces on the compression vanes are treated with a high-tech Diamond-Like Carbon (DLC), giving outstanding hardness, wear resistance and reliability. This enables a significant increase in compressor rotation speed, resulting in a higher displacement volume of up to 50% greater than the previous generation of VRF systems.

As a result of the new compressors design and improved system controls, the operating temperature range has been significantly extended, and is now -5 to +46C for cooling operation and -25C to +15.5C in heating mode.

Heat Exchanger

The system’s heat exchanger has been completely redesigned, using smaller diameter tubes arranged in three rows in the coil, resulting in a 13% increase in surface area, further improving performance and efficiency.

The capacity of the new generation heat exchanger can be adjusted to match the current load and ambient conditions. The new three-way variable heat exchanger enables the VRF’s control system to automatically select the optimum setting.

Continuous Heating

The SMMS-e breaks new ground in being able to provide continuous heating, with no requirement to stop during defrosts, as with rival systems. This is made possible by the use of a new hot-gas bypass control, which simultaneously defrosts outdoor heat exchanger coils, while allowing the indoor unit to continue operating in heating mode.

Advanced intelligent control

For installers, Toshiba has developed Wave Tool Technology (WTT), a wireless commissioning and performance validation tool that enables engineers to read and write data to the condensing unit using their smart phone, enabling testing and commissioning without removing the unit covers.

Schematic of new Toshiba SMMS-e VRF air conditioning heat pump contact wireless commissioning system

This WTT allows service and commissioning engineers to instruct and obtain key system information, simply by touching their smart phone onto the Near Field Communication (NFC) tag located on the outdoor unit. 

The technology simplifies commissioning and reduces the amount of time spent on-site, giving the service engineer the ability to quickly and easily send key system data via e-mail back to the office for analysis.


Importantly, the SMMS-e is available in a wider capacity range than ever before. On the smaller end of the scale, indoor units are now available in capacities of 0.6hp, increasing the number of units that can be connected into a system, making it more flexible. Up the scale, outdoor units can offer up to 22hp on a single module platform, due to a newly developed chassis, reducing footprint, pipework and speeding up installation time.

With the new SMMS-e, it is now possible to connect up to 60hp in a single system, with up to 64 connectable indoor units, beating the previous 48hp maximum by a wide margin.


Improvements in pipe work and connectivity give significant advantages in terms of system design and application. Maximum total pipe work length for SMMS-e is 1000m (double the previous allowable length), with 235m now the maximum allowable distance between an outdoor unit and the farthest indoor unit, another industry first.

A maximum of 40m between indoor units is enough to cover an entire 11-storey building, expanding the application envelope for Toshiba VRF to larger buildings.

Industry first

Finally, in another industry first, the combined compressor, heat exchanger and advanced intelligent control technologies ensure all of the outdoor units in Toshiba’s new SMMS-e VRF range have an ESEER (European Seasonally Adjusted Energy Efficiency Rating) higher than 7, making it a cut above the rest of it’s rivals.

UK:  The British Refrigeration Association (BRA) has responded to the challenges that are facing the refrigeration and air conditioning industry with the new F-Gas Regulation by publishing a comprehensive guide titled ‘Putting into Use Replacement Refrigerants’ (PURR), aimed at helping those involved in managing the changes in refrigerants required by the EU F-Gas legislation.

The PURR Report produced by an Action Group made up of members of the BRA highlights the very real challenges that operators face in sectors such as retail refrigeration in the run up to the 2020 ban on new equipment using refrigerants with a global warming potential (GWP) of more than 2500. Along with the ban on servicing equipment using these refrigerants effective from the same date. Although equipment using reclaimed refrigerant can continue to be operated and serviced up until 2030.

BRA President, Mike Lawrence says “There can be no doubt that spending money on dealing with F-Gas regulation will not be welcomed by the financial directors of most businesses that are affected.”

“However, the PURR Report gives a clear indication of possible approaches to dealing with phase down, and the BRA hopes that this will support good practice.”

R404a in perspective

According to the report it’s estimated that there are between 12,000 to 20,000 systems operating on R404A in the UK (circa 11,000 tonnes) and it’s highly unlikely and generally accepted that NOT all of these will be replaced or charged with new low-GWP refrigerants by 2020.

It is anticipated that a number of systems will be replaced before 2020 as they come to the end of their life or by means of retrofitting.  In such instances it is crucial that owners of R404A systems ensure they manage the removal of the refrigerant, ensuring it is recycled or reclaimed for the servicing of systems that will remain in use on the same site, or another site owned by the same operator after the 2020 deadline.

Should the owner/operator have no requirement to keep the refrigerant the contractor responsible for the removal of the refrigerant is allowed to use it for the servicing of systems elsewhere but is NOT allowed to resell it, and that all reclaimed or recycled F-Gases are labeled with the name and address of the reclamation site or recycling facility. Anyone using reclaimed or recycled product needs to maintain a record of how much they use and where the product was reclaimed or recycled.

The PURR Report is aimed at all stakeholders involved in the commercial refrigeration market – designers, manufacturers, installers, commissioners and end users – and is designed to highlight the challenges the sector faces in the next few years, and offer guidance and suggestions as to how these issues can be dealt with.
