Function

The Caleffi HydroCal™ combination hydraulic, air, and dirt

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 costs as there is no need to include

separate air and dirt separators.

CAUTION: Make sure that all the connecting pipework is water tight. CAUTION: When making the water connections, make sure that the hydronic separator connecting pipework is not mechanically over-stressed. Over time this could cause breakages, with consequent water losses which, in turn, could cause harm to property and/or people. CAUTION: Water temperatures higher than 100°F (38°C) can be dangerous.

Procedure for installation and insulation assembly (only for 2” to 4” sizes) 1. Remove the two black head covers at the ends. 2. Open the two side sections and the lower cap. 3. Install the separator in the system. 4. For cooling applications, consider using a silicon caulk or sealant by spreading a thin layer of sealant over surfaces A and B. Wait for the solvent to evaporate (approx. 10 minutes).
