Ablution Plant - Safe Hot Water with Fluid Category 5 Protection
Part Number: BTHW
The Ablution Plant unit delivers hot water at the required temperature with the highest backflow protection. The primary application is bidets or ablution hoses adjacent to a WC or bidet. The unit can also be used for many other applications requiring hot water with Fluid Category 5 protection.
Toiletry applications are strictly Fluid Category 5, requiring a point of use air gap from the mains water or building supply pipe. There is a duty of care to provide warm water at a safe temperature with suitable legionella controls in place.
The Ablution Plant is contained in a cabinet - with drainage holes in its base - consisting of –
• Break tank with type AB air gap complying with BSEN13077: 2003
• Booster Pump
• Water Heater with thermostat and safety relief valve
• Thermostatic Mixing Valve (TMV3, DO8)
• Controls, fittings and sound proofing
There is a growing need to provide international toiletry facilities. This Ablution Plant helps with Muslim Qadaahul Haajah requirements and also forms part of the performance of Wudhu (Ablution for Prayer). The Ablution Plant is normally behind a removable panel in a washroom and delivers warm water to a trigger operated hose (supplied separately) adjacent to a toilet or bidet. This enables the users to hygienically wash themselves without the need for toilet paper.
• Ablution hose and trigger assy. (CSHT-1)
