New CO₂ chillers and heat pumps

We have now introduced internally mounted standard chillers and industrial heat pumps with an output range of between 30 and 250 kW to our range. Developed and manufactured in Europe, they operate using the environmentally friendly natural refrigerant CO₂ (R-744). They are both safe and efficient to operate and can generate hot water temperatures of up to 90°C. Simultaneous heating and cooling, heat recovery and connection to external, air-cooled gas coolers is possible.
