Marstair CO2 Cassette Evaporators with Hot Gas Heating

An innovative range of cassettes fitted with a CO2 evaporator cooling circuit and a CO2 hot gas heating circuit specifically designed for comfort cooling. These simple to install and quiet evaporators offer the ability to deliver comfort cooling and heating at the higher pressures required for CO2 refrigerant. The hot gas heating circuit is for recycling the waste heat produced from the CO2 pack.

This allows all your refrigeration and air conditioning needs to be supplied through the one CO2 pack, creating a more efficient system and eradicating the need for separate split systems for space cooling and heating.

Units are available with a range of cooling duties from 2.9 to 8.2kW for comfort cooling and a range of heating duties. The lightweight, one-piece, removable chassis allows total access to all mechanical and electrical connections. The units deliver long air throws and low sound levels.
