Description

The HFF300 trainer is designed to train learners in the handling of refrigerants. The installation is based on a refrigeration cycle operating with R134a or R513. It includes the main components of a positive installation, a compressor, a condenser, a liquid tank, an oil separator, a control solenoid valve, an expansion valve, an evaporator and an accumulator. Schrader service valves and fittings allow learners to connect a manifold for loading, recovery and operation verification operations.

The cold room part is simulated by a cabinet. The cabinet door is equipped with an enthalpy diagram with erasable surface (A3 format). A thermostatic control box will control the operation of the solenoid valve (pump-down regulation). Two switches placed on the box are used to stop the operation of the solenoid valve and condenser (this facilitates the adjustment of the pressure switches) and a button allows to bypass the pressure switches to facilitate the removal of manifolds.

The rugged design of this equipment makes it perfectly suited for use in schools. Its anodized aluminum structure on wheels gives it great robustness and flexibility of integration into your premises. In the lower part, the bench has a storage area equipped with two doors with key closure (storage of tools).

The manufacture of this equipment complies with the European machinery directive. This equipment can be used alone or combined with other compatible equipment in our range (see last part of this document).
