Quad

The Quad is a high capacity, natural refrigerant CO₂ heat pump. The Quad delivers water heating capacities ranging from 100kW through to 1400kW (other sizes available on request).

CO2 Refrigerant

The Quad operates using Carbon Dioxide (CO₂) as a refrigerant. CO₂ is a naturally occurring, non toxic and non flammable refrigerant. Whilst being an incredibly sustainable refrigerant, CO₂ is a highly effective working fluid and is perfectly suited to high temperature high capacity and heat pump application.

The unique properties of CO₂ enable the Quad to be an incredibly flexible heat pump solution, able to collect heat energy from a range of sources including Air, Water and waste heat from industrial processes. The Quad can even operate in a simultaneous heating and cooling mode.
