Manifold Type K

Typically installed in the heat pump plant room within buildings, HIRO Type K manifolds can be used for central control and measurement for up to 50 brine circuits used within Geothermal heat recovery systems.

With selectable probe distances of 100, 130 or 150 mm, the manifold can be adapted to the specific inlet/outlet penetration location in the wall or floor and can be configured in relation to the heat pump (right/left).

They are supplied ready for connection with custom-fit wall brackets including cold-insulated clamps which allows the manifold to be fully insulated after installation to prevent condensation.

The flow and return lines are fitted with filling ports and Thermo-manometers to monitor the operating status and the connection to the heat pump can be configured with and without a shut-off valves.
