Description

Refrigerator consists of a hermetic compressor condensing unit, an air condenser and a forced convection evaporator.

The operation is thermostatic type with forced start position for large loads. Temperature from +1°C to +10°C indoors, compliant with European standards.

The refrigerator is a vertical refrigerated display case whose components are far enough apart to be identifiable.

The refrigerator is equipped with instrumentation (flow, temperature, pressure, electrical power) allowing the complete study of the process.

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. The manufacture of this equipment complies with the European machinery directive

The bench is equipped with an electrical box including the safety (circuit breaker, AU, indicators ...) and the display of temperature measurements.
