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 SKS100 is dedicated for potable water preparation with solid fuel heating sources, such as water fireplaces, wood stoves and pellet boilers. 
The SKS100 comes with a 20kW plate heat exchanger and diverting valve. It can deliver 12 l/min of potable water at 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. In case the solid fuel heating source isn’t equipped with a pump, the SKS100 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.
