Electric boiler series SB, 180 - 300 kW

SB 180 - 300 kW

Medium-power series of Varmeteknikk's robust and reliable element boilers.

Supplied for 3-phase power connection in voltages 3x230 V, 3x400 V or 3x690 V. Other voltages can be supplied on request.

The regulator has a simple and user-friendly interface, and regulates the boiler output in 15 steps.

An outdoor sensor can be supplied as an option for optimal economic operation, where the boiler temperature is compensated for the outdoor temperature.

The boilers have digital and analog inputs and outputs for external control and monitoring, so that the boiler can be visualized and controlled from the customer's
SD system/top system. For an additional fee, the boilers can be supplied with a bus coupler for MODbus or BACnet communication.
The boiler can also be controlled directly from the heat pump.

The heating technology boilers are supplied as standard with PN16 flanges.
