Hydraulic Groups

The Hydroblock is an innovative solution that can be readily applied to a wide range of domestic boiler hydraulic circuits. The concept is realised and manufactured by the Italian company, Fugas, who Albion Applications represents in the UK and Eire.
Designed specifically for use with modern compact brazed stainless steel plate heat exchangers or via pipe work to separate heat exchanger, commonly used in current combination boilers, the Hydroblock consists of a pair of brass & plastic assemblies mounted one at each end of the heat exchanger. There are a variety of standard executions for each brass assembly, and overall, the entire hydraulic control function within the boiler is integrated across the two assemblies. The considerable benefits of the Hydroblock are minimised boiler components and boiler size, reduced boiler assembly time and manufacturing cost, increased boiler component reliability. Features of the Hydroblock assemblies include:

Boiler pump connection
Heating flow and return connections
Cold water inlet & hot water outlet connections
Boiler primary flow proving
Tap water flow detection via a differential pressure switch or Hall Effect sensor.
Primary water diverting function – either electrically or hydraulically actuated
Sealed system component connection points (pressure relief valve, pressure & temperature gauges, filling point, drain)
Internal boiler by-pass arrangement to ensure minimum primary flow through boiler

The assemblies can be configured to be attached and sealed to all of the established and available plate heat exchangers, including Alfa Laval, Swep, Giannoni and Zilmet.
The Hydroblock is not limited to combination boilers, with the hydraulic assemblies also being suitable for sealed and open vented heating only boilers. Furthermore, whilst the range of standard Hydroblock assemblies is very comprehensive, Albion Applications and Fugas are keen to work with customers to develop appliance specific derivatives.
The Hydroblock can be supplied bulk packed as individual components or sub-assemblies, or as a fully assembled kit of parts for direct incorporation into the boiler at production stage.
