Cascade productinfo

Modular customised system for any boiler room

The incorporated cascade regulator makes the Ambassador+ the ideal boiler for cascade systems up to twelve boilers. Simple looping and straight-forward connections make the installation easy. With the supplied cascade rack, a capacity of more than two megawatts can be installed in the most inaccessible areas. The system is equipped with adjustable legs and does not have to be anchored to the wall.
