Technical Description

The WL 312.03 heat transfer element enables investigations to be performed on a refrigerant evaporator in the WL 312 unit. For this purpose the component is inserted in the air duct in the base unit using quick action fasteners. The refrigerant connections on the evaporator are self-sealing so that no refrigerant can escape. The WL 312.12 Refrigerant Condensing Unit is necessary for the operation of the evaporator. Refrigerant condenser and evaporator together form a complete refrigerant circuit. The temperatures at the evaporator inlet and outlet are measured using dial thermometers.
