Floor Heating Manifold

FHF-F

Application	The FHF-F Manifold is used for controlling water
	flow in underfloor heating systems. Each pipe
	in the floor heating system is connected to the
	manifold, thus making it possible to control water
	flow or heat supply to each room in the building
	individually.
	The manifold comprises of a supply and return
	manifold. The supply manifold includes individual
	shut-off of each circuit as well as an individual
	flowmeter per circuit. The return manifold is
	equipped with integrated Danfoss pre-setting
	valves securing optimal hydraulic balance in the
	system.
	The valves can be controlled electronically by
	thermal actuators or act as self-acting units by
	means of remote temperature adjusters.
	The manifold is supplied in modules of up to 12
	outlets. Ball valves are available as an option for
	positive shut-off between the manifold and the
	system.
	The end pieces FHF-EM and FHF-EA are supplied
	with manual airvents or alternatively with auto-
	matic airvents.
