Green Circle is a range of bespoke refrigeration and heat pump units produced by specialists in the field — using refrigerants with the lowest possible climate impact and outstanding COP.
Every unit is built by specialists in the field — from our workshops to facilities across the country.
Only media with low global warming potential — without fluorinated compounds and without PFAS. Propane, isobutane, CO₂ and ammonia.
Engineered for a specific purpose. Series production can never match a machine built for your system.
3–8 units of heat for every kWh of electrical energy supplied. Smart, stable and sustainable.
The refrigerants used by Green Circle belong to the group of natural refrigerants and do not contain fluorinated compounds like HFC, HFO or synthetic blended media. They are therefore not part of the PFAS issue that is now receiving increased attention in the EU and internationally.
We review energy sources, temperature requirements and existing systems — and understand your process before drawing anything.
With delivery description and diagram in place, the right refrigerant and dimensioning are selected.
The units are built and fully completed at our facilities — usually as part of a larger energy system with pumps, shunts, tanks and automation.
In our modern FAT station, the units are thoroughly tested, adjusted and optimized before delivery. The machines are run under real operating conditions — with the temperatures and loads they will work with at the end customer. This allows us to verify function, capacity and energy efficiency, and document performance before the plant leaves the factory.
For many projects, we also handle installation and commissioning, giving the customer a secure transition from production to stable operation. With careful planning, tidy execution and thorough testing, we ensure an efficient start-up and a reliable plant from day one.
