Heating unit HEATFLOW 3 kW 400 V, pump 400 W

Provides frost-protected water in insulated water circuits (¾" or 1" pipe)
The heating units of the HEATFLOW series are available with heating power from 3 to 12 kW and especially developped for large free stalls for cattle, horses, pigs and sheep. 4 different heating units are available (see list below).
The heating elements heat up a secondary water, which transfers the heat to the primary water. A maximum temperature of 40°C reduces the appearance of lime to a minimum. Therefore the HEATFLOW is especially developed for keeping circuit pipes with limy water frost-free!
With return flow temperature control: Desired temperature of return water flowis regulated by a sensor mounted on the return flow pipe. If return water flow temperature is lower than the adjusted value, the heating element will be automatically switched on.
Expandable: you can add another heating element to HEATFLOW units with one heating element. The heating power will then be doubled (e.g. 3+3 kW or 6+6 kW). For example if you extend your barn.
Equipped with a high-capacity circulation pump with stainless steel base (230 V, 400 W)
Water connections are hold in 1". For easy installation the HEATFLOW units are delivered with two armoured tubes.
The heating elements are equipped with an overheating protection (STC)
Scope of delivery includes vent-valve, pressure relief valve, non-return valve, and non-return flap
Two residual-current devices 30mA have to be provided by the customer. They serve to secure the pump and the heating element in a separated way.
