"Highly effective in preventing fuel theft and diesel spillages" - Chris Smith, Fleet Engineer, Imperial Tankers
The Impregnable is the only anti-siphon to prevent ANY fuel loss due to its unique floatvalve that allows fuel to flow into the tank, but locks off once filling is stopped, meaning no fuel can be siphoned.
Customers include: Tesco, Sainsburys, Imperial Tankers, Wincanton, DHL, Maritime Transport
"Easy to fit and effective in preventing fuel theft" - Steve Sugden, Fleet Engineer, WH Malcolm
As the shortest anti-siphon on the market, the Standard is an excellent deterrent against 3rd Party Theft. However, it will not prevent diesel spills or skimming small amounts of fuel from the top of the tank.
Customers include: W H Malcolm, Reality, Hanbury Davies, Benton Bros, FreshLinc, Fraikin
Standard anti-siphons are good deterrents against 3rd party theft, however, they do NOT stop skimming. As much as 80 litres of fuel is still exposed to theft with a standard device fitted.
