CO2 Evaporator - Continuous evaporation by ambient air heating - Union

Continuous evaporation of liquid CO₂ by ambient air heating.

The unit consists of two separate heat exchangers, which switches between operation and defrosting, to ensure a continuous evaporation.

The heat exchangers are mounted onto a rigid frame with piping, valves, instruments and control panel for automatic operation of the unit.

The heat exchangers are made in two versions dependant on the environment. Either the CU version with aluminium finned cobber coils mounted in a powder coated casing or a SS version with stainless steel coils and a galvanized steel casing for more aggressive climate conditions. Both versions come with a galvanized frame. Equipped with low noise fans specifically designed to maintain uniform low velocity airflow to ensure that water formed during defrosting is retained within the casing and led to drainage. A timer unit opens the solenoid valves alternately so that one unit is open to CO₂ while the other is closed. When the tube bank is closed, the ambient air drawn through the unit defrosts the water ice formed during the “open tube bank“ cycle. The water collected in the aluminum drip tray during the defrost cycle is led to drainage. The evaporator is designed for installation inside a building.

Benefits:

• Continuous operation & defrost mode
• Easy-install and maintenance. Vertically adjustable drip tray & removable inner drip tray. Hinged side panels
• Low noise fans
• Two versions CU and SS for aggressive climate conditions
