Product Description

EFFICIENCY IN HEATING TECHNOLOGY

The trainer contains a complete closed heating circuit with circulating pump, electrical heater, convector for dissipating heat, various pipe sections, fittings and safety devices.

The losses of the most important fittings can be determined using seven differential pressure sensors. Control response and energy flux can be plotted using four temperature sensors, a flow rate sensor and an effective power sensor. The characteristics of a conventional circulating pump and a differential pressure controlled circulating pump can be compared.

The measured values are transmitted directly to a PC via USB and can be processed with the supplied software. Both circulating pumps, the heater and the convector fan can be controlled via PC.
