• Gerni is launching a type of lance that will greatly improve the performance of its highpressure cleaners. A small turbine in the head of the lance drives an oscillating nozzle which sends out a jet of water instead of the fine atomised spray from an ordinary nozzle.
Gerni claims that the jet, called the Turbo Laser, loses 15% of its striking power over a 20cm range, whereas a conventional nozzle may lose more than 85%. The jet from the Turbo Laser, which oscillates up to 200 times a second, also holds its heat better than an atomised spray.
By using the pressure from the pump efficiently, Gerni claims that cleaning work that would previously have required three-phase electrical power can now be done with singlephase electricity. Jobs that would have required the pump working at maximum capacity can now be done without working the pump flat out.
The Turbo Laser will be available only for use with Gerni pumps and although it will be available to existing Gerni users, it will not be available on its own for use with other pumps. The pumps use a diesel-fired heater that is controlled by a thermostat, as temperatures above 70°C damage the Turbo Laser.
The turbine is made from a new plastic called Peek, and is housed in a brass casting. An overhaul kit costs 229. vvill Genii Turbo 69
