Cascade boilers

DESCRIPTION

• The cascade boilers unit is composed of 2 traditional fuel and floor boilers (possibility gas or fuel/gas).

• The unit feeds 2 circuits at 2 temperature levels.

• The unit can be connected to the TCF 120 (not included) on which it dispelles the thermal production.

• The working is madeby a regulator.

• The unit can work independently thanks to 2 exchangers with plates (one per circuit) that dispell on a unit heater.
