Application
The Caleffi HYDROCAL™ combination air, dirt and hydro separator is a device that
incorporates high performance air and dirt removal functionality into the hydro separa-
tion function which makes the primary and secondary circuits connected to it hydrauli-
cally independent, and can be used on hot or chilled water systems. The HYDROCAL
features a proven stainless steel internal element that combines to continuously and
automatically eliminate 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 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.
Typical Specification
Furnish and install on the plans and described herein, a Caleffi HYDROCAL as manu-
factured by Caleffi. Each separator must be designed with an epoxy resin painted steel
body, 300 series stainless steel internal coalescing mesh, a brass blowdown drain valve
and automatic brass air vent with brass shutoff valve. The separator design must
include ANSI B16.5 Class 150 RF flanges. The separator must be designed and built
in accordance with Section VIII, Div. 1 of the ASME Boiler and Pressure Vessel Code
and tagged and registered with the National Board of Boiler and Pressure Vessel
inspector, CRN Registered, and stamped for 150 psi (10 bar) working pressure, with
ASME U stamp. Each separator shall be Caleffi model NA549 or approved equal. (See
product instructions for specific installation information.)

Flow Capacity
Hydraulic characteristics
The HYDROCAL should be sized according to the maximum flow rate
value at the inlet. The selected design value must be the greatest
required flow rate of either the primary circuit or the secondard circuit.
