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
separation function which makes the primary and secondary circuits connected to it
hydraulically 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
manufactured by Caleffi. Each separator must be designed with an epoxy resin
painted steel body, 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 constructed in accordance with the latest revision of
the ASME Boiler and Pressure Vessel Code, CRN Registered, and stamped for 150
psi (10 bar) working pressure. Each separator shall be Caleffi model NA549 or
approved equal. (See product instructions for specific installation information.)
