Hydraulic separator IVAR.HS 220 for IVAR.HC-DN 40 and HC-DN 50 manifolds – 33 000 l/h, DN 100 flanges

Product detailed description

The IVAR.HS 220 hydraulic separator (low-loss header, code IVA49043689) is used where several heat sources operate on the primary side or several heating circuits on the secondary side. It hydraulically decouples the boiler circuit from the consumer circuits and balances the dynamic pressures according to the flow rates on both sides, so the pumps do not affect each other. It connects to the IVAR.HC-DN 40 and IVAR.HC-DN 50 horizontal manifolds.

How it works

The 220 mm main chamber slows the flow from 1.00 m/s at the inlet to 0.26 m/s, reducing mixing of the water. A stratification deflector maintains temperature layering and helps separate air, dirt and sludge. The 2 × 1/2" F and 1 × 2" F connections are for a sensor, an air vent and sludge draining.

Installation

The delivery includes the separator body with thermal insulation. The IVAR.CONNECTA PHS floor support (IVA49018215), CONNECTA F counter-flanges (IVA49065735) and the CONNECTA VC set of bolts, nuts and gaskets (IVA49156710) are ordered separately. The primary and secondary circuits must each have their own circulation pump. The installation site must be dry, protected from frost and UV radiation and have sufficient load-bearing capacity. Installation should be done by a specialist company; flush the system before start-up.

Frequently asked questions

When is a hydraulic separator needed?
When several heat sources operate on the primary side or several heating circuits with their own pumps on the secondary side. The separator balances the dynamic pressures between circuits and eliminates problems caused by fluctuating flow rate and pump head.

Does every circuit need its own pump?
Yes. With the IVAR.HS 220, both the primary and secondary circuits must be fitted with a circulation pump; the primary circuit then runs at constant flow and the secondary circuits at variable flow.

Does the separator also remove air and sludge?
Yes, the stratification deflector in the main chamber helps separate air and dirt and lets sludge settle. Threaded 1/2" F and 2" F connections are provided for venting and sludge draining.

Is a floor support included?
No, the separator body is supplied with thermal insulation. The IVAR.CONNECTA PHS floor support (IVA49018215), counter-flanges and the bolt set are ordered separately.
