Manifold Chambers L

HIRO manifold chambers L provide security as well as central location for controlling and monitoring the flow and pressure of up to 16 brine circiuts and are typically used for large domestic geothermal ground source heat recovery systems.

The probe connecting pipes have been welded to the manifold chamber with three-fold leak-proof welds and are ready for jointing with electrofusion fittings. All manifold devices are pressure tested at the factory. The chambers are equipped with a high-quality, storm watertight, UV-resistant plastic (PE/PP) lid, rated Class A35. This means it can withstand wheel loads of up to 3.5 t.
