The new 1" stainless steel (AISI 304) manifold for radiant floor heating systems.


INOXRAD is the Onda stainless steel (AISI 304) manifold for radiant heating systems; it’s targeted for residential radiant applications and it’s available in 1” size from two to thirteen heating loops. The configured flow rate is set on the top meter for each circuit. Return rail can be controlled electronically by thermal actuators. The particular design of the manifold reduces pressure drops and minimizes boiler circulator pump force.

Inoxrad consists of:

  • one supply manifold with flow meters (scale 0/5 lit/min), air vent and drain valve at the end

  • one return manifold with shut-off valves, air vent and drain valve at the end. It’s suitable for actuators with 30 x 1,5 mm. thread

  • pair of mounting metal brackets
