Function
The Caleffi SEP4™ combination separator is a device that
incorporates four critical functions for hot or chilled water sys-
tems. 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 perfor-
mance 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 sys-
tem, the added powerful removable external magnet belt (union)
or probe(s) (flanged) in the lower body removes up to 100% of the
ferrous impurities, including magnetite, that can form in a hydronic
system. The SEP4™ has 2½ times the ferrous impurities removal
performance of standard air and dirt separators.
