The Caleffi HYDROCAL™ combination air, dirt and hydraulic separator incorporates high performance air removal, high performance dirt removal and high performance hydraulic separation all in one device. The 3-in-1 functionality minimizes costs for systems requiring primary/secondary piping because there is no need to install separate air separators and/or dirt elimination devices.
 

The HYDROCAL features a proven stainless internal element that continuously and automatically eliminates air and captures dirt. Both undissolved and dissolved air is removed through coalescing action. Over time dirt particles as small as 5 microns are separated out and trapped in the bottom of the unit away from flow path. The unit comes with an automatic high-capacity air vent with a service valve and drain valve for blowing down dirt without taking the system offline.
 

Caleffi HYDROCALs are ASME registered and available in 2-inch to 6-inch sizes with ANSI flanges and insulation. Flow rates range from 37 GPM to 376 GPM. Non-ASME models are also available in 2-inch to 4-inch sizes. HYDROCALs are rated for either hot or chilled water systems.
