Description

The HFF100 trainer is designed to train the learners in the transfer of refrigerants. The installation is based on a refrigerating cycle operating with R1234YF. It comprises the main components of a positive installation, a compressor, a condenser, a receiver, a solenoid control valve, an expansion valve, an evaporator and a suction line accumulator. Service valves and fittings Schrader type allow the learners to connect a manifold for the load operations, recovery operation and verification operation.

The cold chamber is simulated by a cabinet. The cabinet door is equipped with an enthalpy diagram R1234YF with erasable surface (format A3). A thermostatic control box will control the operation of the solenoid valve (pump down control). Two switches located on the box are used to stop the operation of the solenoid valve and of the condenser (this facilitates adjustment of the pressure switches).

The robust design of this equipment makes it perfectly suited for use in schools. Its anodized aluminum structure on wheels makes it extremely robust as well as a great flexibility of integration into your premises. In the lower part, the bench comprises a storage area equipped with two doors with key locking (storage of tooling).

The manufacturing of this equipment meets European machine directive

This equipment can be used alone or with other compatible equipment in our range (see last section of this document).

The bench is installed on an aluminum profile structure equipped with four braked-directional castors. It has an electrical box with a 30mA RCD.

The bench also includes:
-a power supply module with a differential circuit breaker and a 2P+ T socket for connecting the accessories (pump, recovering station ...)

-a digital thermostatic control box with probe in the chamber. The controller controls the solenoid valve (control pump down). Two switches are used to stop the operation of the condenser and the solenoid valve (adjusting pressure switches).

-a cold chamber simulated by a cabinet. The cabinet door is equipped with an enthalpy diagram R1234YF with erasable surface (format A3).

-a storage area in the lower part of the frame with two access doors. A key lock is used to secure the storage.
