Function
The Caleffi HYDROCAL™ combination air, dirt and hydraulic
separator is a device that combines high performance air and dirt
removal with hydraulic separation. Primary and secondary circuits
connected to it become hydraulically decoupled thus eliminating
pump conflict.
A proven, time tested stainless steel internal coalescing element
continuously and automatically eliminates all entrained air,
including microbubbles, in the system. Air discharge capacity is
very high. Over time, dirt particles as tiny as 5 microns are captured
and collected away from the flow stream.
The 3 in 1 high performance functionality of the HYDROCAL saves
system installation and maintenance cost as there is no need to
include separate air and dirt separators. It can be used on either
hot or chilled water systems.
