Teaching suggested applications*

The ERT105 unit allows the study of a reversible domestic heat pump of the ATLANTIC brand. It is equipped with a dissipation circuit and a buffer tank. This avoids short cycles and gives students time to make adjustments and reading. The outdoor unit is positioned on the main frame of the bench. The hydraulic circuit consists of the primary circuit of the indoor unit, a buffer tank and a dissipation circuit. The dissipation circuit includes an electronic circulator with variable speed (HMt or flow regulation), a balancing valve on the return and two quick couplings for the connection of the dissipation units (unit heater, fan coil, etc.). The bench is fully instrumented to allow maximum educational use. A supervision system can be added as an option.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machine Directive.

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