Enviro-Vac have introduced a new wet injection system to the market, featuring adjustment-free needles. Compliant with PAS 60-1 the new system has superceded the conventional arrangement of manual flow adjustment at each needle - replacing it with a self-regulating "needle-module".
Inside each needle-module is a unique pressure control valve which can deliver a consistent, balanced output to each needle ensuring that the requirements of PAS 60-1 are met.
In conjunction with the needle-module a new surfactant pump-delivery system (shown below) has also been developed, which:
|
►is a robust, durable, all plastic construction.
►features a powerful pump capable of reliably delivering fluid even when 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 125 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, so 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 that a consistent liquid flow of 35ml per minute (+/- 10%) is delivered to each needle.
