R146I

Hydraulic separator with insulation

Description

In modern hydraulic installations the R146I hydraulic separator performs the
following functions:
• Hydraulic separator: makes connected hydraulic circuits independent, preventing
any reciprocal influence between circulators installed in series and compensating
the difference of flows through the circuits, all according to the characteristics of
their corresponding circulator;
• Dirt separator: separates and eliminates any debris inside the circuits through a
valve to be connected to the discharge piping;
• Deaerator: separates and eliminates the air inside the circuits through the air vent
valve placed on the separator upper connection.
The hydraulic separators are equipped with insulation to guarantee adequate
thermal insulation.

Operation

The R146I hydraulic separator enables to decouple the primary circulator flow from the secondary.
When the flow running through a primary or secondary circuit exceeds the one circulating in the other, the separator bypasses part of the flow. This results in a production circuit featuring a constant flow and a distribution circuit with avariable flow.
