The Hydrocell18 comprises all the features of its’ predecessors, but with a few additional features:

1. Suitable for both cistern fed and direct feed urinals
2. KUKReg4 compliant.
3. Various settings for all building types
4. Includes Arena setting for low frequency, high intensive use.

The Hydrocell is the only control on the market that helps the installer to select the correct flushing volume to comply with Water Regulation, Installation notes.

The specific regulation for those interested is the IRN R075, Schedule 2.25(4).  (IRN stands for Installation Requirement Note). The details of which is shown below and attached.

Schedule 2.25(4)

(4) The requirement in sub-paragraph (1)(i) of  Schedule 2.25(4) shall be deemed to be satisfied if, (a) in the case of an automatically operated flushing cistern servicing urinals which is filled with water at a rate not exceeding –

(i) 10 litres per hour for a cistern serving a single urinal;

(ii) 7.5 litres per hour per urinal bowl or stall, or, as the case may be, for each 700mm width of urinal slab, for a cistern serving two or more urinals;

(b) in the case of a manually or automatically operated pressure flushing valve used for flushing urinals which delivers not more than 1.5 litres per bowl or position each time the device is operated.

We have calculated maximum flushes per hour to ensure the correctly selected program complies.

Direct flushing : This is for urinals without a cistern, thus they are fed with a direct water supply. Our solenoid valve has a max flow rate of 5.7Lpm at 5 bar, thus the flush volume on setting DF2 (10 sec flush) , would dispense 0.95 of a litre per flush at 5 bar.

(NB: Direct feed systems should also have a vent or pipe- interrupter to comply with Regs).
