Preventing drain pollution
May 1st 2007 Designed for emergency sealing of
pipes and drains, the portable
Envirovalve introduced by Darcy
Products provides a simple, easilydeployed
method of preventing
spilled or leaking pollutant from
flowing into the drainage system.
By using a lance and inflatable
bladder, sealing can be carried out
rapidly even in deep manholes,
without the need for confined
space equipment.
Developed in conjunction with
the emergency services and the
Environment Agency, the unit
consists of an easily assembled
lance and lance holder with quick
release coupling, inflatable bladder
with grip suitable for sealing all
pipes from 100 to 375mm
diameter, and a high pressure
pump for rapid inflation. A retaining
rope is provided for bladder
recovery.
In addition, the company
provides a wide range of related
services, including training. More articles from Darcy Products Limited: |
