  • If you want to know the minute your dosing system has any problems this is the hose for you.
  • PF-Detect will sound an alarm, send a signal to switch off your dosing pump and give you the chance to get your reserve line working within seconds of a hose failure.
  • The fear of aggressive chemicals getting out into the environment, due to undetected leaks, was the reason behind the development of dual containment Hose. With PF-Detect this fear can be almost eradicated!
  • The leak detection system only requires a minimal amount of liquid to trigger the alarm and shut off procedure, with the leaked liquid contained by the versatile polyurethane jacket.
  • With attractive per metre costs and the potential to forego the expense of catch pots, PF-Detect really offers anyone who wishes to save money, without cutting corners
  • An exciting opportunity to put in the very latest system available.
  • * WRAS approved for the conveyance of water up to 23°C - Approval Number 2005503.
