HTWT - Mobile Test Unit

The HTWT has been developed to enable pressure testing of waterway equipment without the need for an external pump or power source.

The unit, which is fully mobile, comprises of a CE marked 63 litre or 130 litre stainless steel water storage cylinder, a pressurising air cylinder and associated controls.

Operation of the unit is a simple case of filling the storage cylinder with water, connecting to the equipment requiring test – Dry Riser / Fire Hose etc. – opening the water outlet valve, then opening the air supply valve and adjusting the regulator to the desired test pressure.

Once the test has completed the air supply is shut off, and the vent valve opened.

The HTWT is fitted with a standard 9 Litre 200 Bar compressed air BA cylinder.

It has an adjustable pressure regulator and a 15 Bar pressure relief valve is fitted to avoid over pressurisation.

The standard unit is supplied with, 2 x 3mtr length of 25mm rigid wall tubing, fitted with Storz D both ends. There is also an adaptor kit included, comprising of 1 x Storz D x 2.5 Inst Male. 1 x Storz D x 2.5 Inst Female. 2 x Storz D x 1" Hose Tail.

The unit is filled by connecting a water supply using the adaptors supplied, and opening the inlet and vent valve until full.

Where the water requirement exceeds 50 Litres the unit can be refilled during the test procedure.
