Alubox X-treme boilers can be used as a single boiler or as
cascade for up to 16 boilers.
Particularly during the season passes, the heat requirement of the
system may be very low. Cascade systems run only 1 boiler to meet
this low heat requirement and provide efficient operation. In the
same way, cascade systems, can activate all of the boilers when
heat demand increased, saves energy by operating in a wide range
of modulation.
Boilers in the cascade system share the heat load evenly. Master
Boiler's EQUAL AGING function ensures that each boiler works
evenly, ensuring high efficiency and long life time.
In cascade systems, one of the boilers is used as MASTER
(LEADER), others are used as SLAVES (FOLLOWERS). While all
settings of the cascade system are done via the MASTER boiler,
SLAVE boilers work under the control of the MASTER boiler.
