Function

The Caleffi SEP4™ combination separator is a device that
incorporates four critical functions for hot or chilled water systems.
It combines high performance air and dirt (magnetic and non-
magnetic) removal into the hydraulic separation function which makes
the primary and secondary circuits connected to it hydraulically
independent. The SEP4™ features an internal coalescing element
that continuously and automatically eliminates air micro-bubbles with
the simultaneous removal of dirt particles as tiny as 5 microns. The
air discharge capacity is very high, with the capability of automatically
removing all the air present in the system down to the micro-bubble
level. The 4-in-1 high performance functionality of the SEP4™ saves
system installation and maintenance costs as there is no need to
include separate air and dirt separators. In addition to removing solid
impurities in the system without isolating the separator or shutting
down the system, the added powerful removable external magnet
belt (union) or probe(s) (flanged) in the lower body removes up to
hydraulic, air, dirt and magnetic separator in steel
