HVAC Components for Air Source & Ground Source Heat Pump Manufacturers
We work with heat pump manufacturers, assisting them with their system design to help deliver greater product efficiency.
In addition to compressors with inverter control and heat exchangers optimised for heat pump applications, we can recommend compatible valves, line components and safety cutouts to complete your design.

Compressors and Inverter Drives
Heat pump performance is driven by the compressor chosen for your application. We recommend inverter-driven compressors from SCI, an innovative Thai producer that manufactures 4 million refrigeration compressors a year. Compressors can be matched with a selection of three different inverter control options, giving greater design flexibility.

Heat Exchangers
Sanhua is our recommended choice for R290 heat pump heat exchangers. With their horizontal flow, Sanhua's micro-channel heat exchangers provide excellent heat transfer compared to traditional fin and tube coils. A wide range of brazed plate heat exchangers benefit from a patented asymmetric plate design to give a 25% lower pressure drop on the secondary side.

A Few Examples of What We Do
Scroll Compressors for European OEM
We supply 1,500 vertical scroll compressors a month to a major heat pump manufacturer in Europe. The SCI compressors are integrated into a R290 inverter-driven monobloc heat pump, which delivers an impressively high efficiency of 5.55 COP.
Design Support for Heat Pump Start-Up
We've been advising a newly-established heat pump provider with detailed product support spanning multiple heat pump components. With a focus on reliability, we have designed a package of components that meet their stringent test conditions.
Heat Pump Safety
We supply ceramic bimetallic thermostats with auto reset function that is rated up to a maximum of 230C, ideal for use in overheat protection of heat pump back up heaters.
