Heating substation SK-3V


Heating,- floor heating+ air conditioning + for domestic hot water (DHW) systems

Subsidiary company Ecoterm designed two heating and DHW substation for apartments and industrial buildings connecting to district heating systems.
SK-3V is fitted with brazed plate heat exchangers, heat-surface plates, the material is stainless steel (AISI 304 or 316).
SK-3V substation is effective – compact and lightweight. The substation is equipped with standard components.
SK-3V compact heat substation are easy to carrying and delivery time is short.

Construction and installation

SK-3V The substation is delivered to the customer as ready for installation,
all the components installed on a frame. Heat distribution substation is connecting to the district heating piping systems and secondary heating, floor heating or air conditioning.
Connecting to the power supply 230/400 V, and the outdoor sensor.


Pre-fabricated heat substation standard equipment includes:

  • Insulated (brazed or openable) plate
  • Electronic controls and sensors
  • Control valves with actuators
  • Circulation pumps.
  • Pump control box
