Wet-Injection Equipment


Controlled Wet Injection System Hire

Compliant to BS8520-1/PAS60-1.


Manufactured by Enviro-Vac this injection system has adjustment-free needles.


This system supercedes the conventional arrangement of manual flow adjustment at each needle - replacing these with self-regulating "needle-modules".

Inside each needle-module is a pressure control valve which delivers a consistent, balanced output to each needle ensuring the requirements of BS 8520-1 &  PAS 60-1 are met.

Used in conjunction with the needle-module is a pumped wetting-agent delivery system (shown below), which:

►has robust, durable, all plastic construction. 
►features a pump capable of reliably delivering fluid even where the injection needles are elevated many meters above the pump unit. 
►allows needles to be used in any combination up to a maximum of 100 without compromising the flowrate at each needle.
►has a 100+ litre capacity transluscent tank with capacity graduations. 
►will self-mix the surfactant. 
►incorporates multi-stage liquid-filtration to prevent surfactant-borne debris blocking the needles. 
►features factory-set automatic pressure regulating valves requiring no adjustment, minimising the opportunity for operator error.
►has a "Dwell-Time" feature allowing a repeating cycle of 5 minutes injection followed by 5 minutes waiting - to allow the fluid to be absorbed.  This can be over-ridden for constant injection or spray application.

For work at different levels, the pump system can be left on the ground floor and a light-weight pressure control box taken to the higher levels - connected to the pump system by a single quick release hose.

The control unit compensates changes in pressure-head which

occur when needles are used at a different level from the pump unit, and ensures consistent liquid flow of 35ml per minute (+/- 10%) is delivered to each needle.
