Reciprocating Compressors
Hermetic refrigerant compressors for use in commercial refrigeration systems.
Operating under the brand name Cubigel Compressors, this complete range of hermetic reciprocating compressors for the light commercial refrigeration market are manufactured by Global brand Huayi compressors in Barcelona, Spain. Huayi are a well-respected and trusted hermetic compressor and capital equipment manufacturer, they’re ranked top in the compressor industry in China, with an annual production output of over 10 million hermetic compressors and $300 million turnover.
We're an official longstanding supplier, and integration partner for Cubigel compressors.
With over 30 years in the commercial refrigeration and HVAC markets, Axair Refrigeration are trusted with large contracts, stock holding, and integration of refrigeration compressors to support the business and technical operations of many UK and International original equipment manufacturers.
Reciprocating compressors like those manufactured under the Cubigel brand are one of the most widely used compressor technologies suitable for refrigeration applications with very high cooling capacity requirements. They feature a piston and cylinder arrangement like a car engine. The refrigerant inside the cylinder gets compressed by the reciprocating motion of the piston. Each cylinder has a suction valve and discharge valve to distribute the gas to the condenser after compression. There are three types of reciprocating compressor; hermetic, semi hermetic and open.
A hermetic refrigeration compressor is one in which the electric motor and compressor are enclosed or sealed in a hermetically welded envelope and the motor is cooled by the refrigerant itself. Hermetically sealed compressors are airtight units that prevent the leakage of refrigerants and offer a compact, low noise, long life product that is easy to install and requires less maintenance.
Innovative research & development by Cubigel has evolved a range of reciprocating compressors optimised for energy efficiency with the aim to reduce the effects of global warming and aid the production of safer, more environmentally friendly refrigeration systems.

The advanced design of Cubigel Compressors® Green Cooling ranges allows a remarkable efficiency improvement by becoming the most suitable component for a sustainable refrigeration application.
The compressors are suitable for Natural Refrigerants such as propane (R290) and isobutene (R600a), which have being introduced in commercial appliances, not only due to the replacement of HFCs refrigerants which have a high impact on the environment, but also because it is more efficient in terms of performance and applications energy consumption.
The Cubigel R&D team has strongly and successfully worked on an environmental alternative to obsolete refrigerants - with no direct effect on global warming - reducing the energy consumption by using natural refrigerants with no greenhouse effect (R290) and developing High Efficiency compressor ranges.
Propane (R290) has no direct contribution to global warming and when used in an application, its energy consumption is between 12 to 15% lower than a similar application with R404A. Additionally, propane has better dynamic behaviour showing a lower increase of energy consumption with increasing ambient temperatures.
R290 compressors offer a higher cooling capacity and COP, allowing energy-saving consumption with smaller displacement. The major environmental benefits are obtained combining the use of the R290 with the design criteria of our high efficiency range compressors. These compressor models, in their more advanced versions, can save up to 35% of energy when compared with standard efficiency series of R404A, thanks to very flexible asynchronous motors that can adjust to different energy consumption levels by connecting, or not, a permanent capacitor.

Variable Speed Compressors
Variable Speed offers the lowest applications' energy consumption by means of electronically self-adjusting the compressors speed to the appliance cooling needs, while improving COP up to 50%.
Commercial refrigeration manufacturers are focusing their efforts to produce more efficient applications in order to satisfy the needs of reducing operating costs of the refrigeration equipment installed in supermarkets, retail premises and restaurants, where saving energy has become a topic of the major concern.
Variable Speed Compressors are available for R134a with GLT99FSN in HMBP application model and for R290 with NPT12FSC (LBP) and NLT60FSN (HMBP). With these 2 last models, a major benefit has been obtained from the use of Natural Refrigerants: A better performance and the avoidance of contributing to global warming.
The accurate design of the application and the right selection of the components -such as efficient compressors, fan motors, greater insulation thickness of the cabinet walls, larger condensers, low consumption lighting - is the key to reducing the total energy consumption of the application. The compressor is one of the components with highest impact in terms of energy consumption in the appliance.
Variable Speed Compressors are the solution for obtaining the maximum energy reduction, basically because full compressor capacity is not always needed, so this technology dynamically adapts the compressor's cooling capacity to the appliance's needs by adopting electronically-controlled running speed, optimizing the system's performance.
• Possibility of covering several standard compressor models of different cabinet volumes with just one compressor model.
• Compressor power consumption reduction up to 45% and 50% in comparison to standard compressors. This energy saving can be over 40% considering the total appliance power consumption (just due to the compressor).
• Reduces the pull-down time by means of running at a higher speed when it is needed.
• Reduces the number of start-ups/stops of the compressor.
• Modifies the speed until the achieving the longest duty cycle possible.
• Lower noise level
• Longer expected compressor life due to the fact that the compressor is usually running at a lower speed than a standard compressor.
• Drop in electronic driver system for automatically self-adapting the compressor speed to the current thermal load by means of the "Smart Speed" programming option.
• Compatible for electromechanical and electronic thermostats.

The advanced design of Cubigels green cooling range is one of the most sustainable hermetic compressor offerings in the marketplace, allowing a substantial efficiency improvement over conventional models with reductions in energy consumption of up to 45% in refrigeration appliances. Consequently, delivering lower Co2 emissions into the atmosphere. The Green Cooling range benefits from high efficiency, natural refrigerants, and variable speed control options; the crucial benefit of reducing energy consumption by electronically controlling the motor.Â
The green cooling range improves the compressor COP between 20-30% when compared to standard ranges.
Major environmental benefits are obtained combining the use of R290 with the design criteria of high efficiency ranges. These more advanced compressor models can save up to 50% of energy compared with standard series of R404A thanks to its high efficiency mechanics, advanced motor winding design and the optional running capacitor concept.Â
The High Efficiency models reduce energy consumption of commercial refrigeration appliances between 10% and 30% with respect to standard ranges. Most High-Efficiency models are equipped with electric motors, designed with the "optional run capacitor" concept, that is, the compressor can work with or without a running capacitor (CSR/CSIR), offering the level of efficiency with the same compressor.
Natural refrigerants like propane (R290) and isobutene (R600a) are being gradually introduced in commercial appliances, not only due to the replacement of H-CFC’s and HFC’s refrigerants which have high impact on environment,
but also because it is more efficient in terms of performance and applications' energy consumption.
Refrigerant propane has no direct contribution to global warming and its energy consumption is between 15% to 20% lower than a similar application with R404A. The Cubigel Compressors® R290 compressors offer a higher cooling capacity and COP allowing energy-saving consumption with smaller displacement.
The Variable Speed Compressor offers the lowest energy consumption by means of electronically self- adjusting the compressor’s speed to the appliance’s cooling needs, while improving COP up to 40%.
Using Drop-in solution with communication capabilities, this compressor automatically achieves the best efficiency for the appliance while dynamically adapting the compressor’s speed to the needed cooling capacity.
