– Connection box IP43.
A range of duct or ambient temperature sensors and controllers accessories to accompany the electric heater are available. These controller accessories modulate the heater output as a function of the required environmental temperature. With this system it is possible to achieve temperature rise up to 50º on the supply air.

– Can be mounted horizontally or vertically.
– Connections with watertight seals.
– Connection must be made between the coil and the hot water circuit.

– Maximum temperature: 100ºC.

Shut-off valves must be installed on each water connection, so that the unit can be isolated if necessary (for cleaning filters, repairs, etc.) without the need to drain the entire circuit.
We recommend installing a filtration box with a filter (MFL-F + MFR) at the input to the unit, to capture water borne debris.
