Separation unit


  • Preassembled and pressure tested unit
  • Easy and quick installation
  • Potable water preparation
  • Flexible design with the possibility of upgrade
  • Dedicated unit controller
  • Ensures the system compliance with INAIL

Series SKC100 is dedicated to separate two heating devices, as well as potable water preparation.  
The SKC100 comes with a 30kW plate heat exchanger, a Wilo PARA 8m pump, check valve, diverting valve and 20kW plate heat exchanger for potable water preparation. The unit can deliver 12 l/min of potable hot water with a temperature of 45°C. 
The unit can be equipped with a controller CSK211 (available as accessory) to switch on the pump if the heating source for portable hot water preparation has reached working temperature, as well as turning off the gas or oil boiler, in case of solid fuel boiler usage. In case the solid fuel heating source isn’t equipped with a pump, the SKC111 is prepared for a smooth installation of pump (available as accessory).
For anti-scalding protection, ESBE is recommending one of the thermostatic mixing valves available in ESBE product portfolio.
