Description

The ERT140 bench allows the study of a domestic heat pump of DE DIETRICH brand. It is equipped with two circuits (an inner circuit and an outer circuit) comprising buffer tanks. This will avoid short cycles and allow students time to make adjustments and get records. The evaporator load side is realized by an electrical heater situated in the tank but it is also possible to connect the circuit on a dissipation loop or optional dissipation module. The condenser load side is realized by an optional dissipation module (see last section of this document) to be selected based on the expected applications. Each circuit consists of a primary circuit (between the Heat Pump and the tank) and a secondary circuit (between the tank and dissipation).

The bench is fully instrumented to allow maximum educational use. There can be added an optional monitoring system.

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 great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.

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