MAINTENANCE engineers visiting the transport service equipment section at the Commercial Motor Show will probably find the time spent there more rewarding than at any previous post-war Exhibition. The latest appliances for vehicle cleaning, engine reconditioning and general fitting are striking in their number, ingenuity and efficiency of design, and give evidence that makers are keeping up with vehicle manufacturers in progress towards utmost economy.
One of the major problems involved in the use of steam cleaners, that of scaling, has been almost eliminated, it is claimed, by the design of the cleaner exhibited on Stand 184 by D. Wickham and Co., Ltd., Ware.
Oil or Paraffin
Advantage has been taken of the experience gained with the German Thermikus machine. The Wickham cleaner has an electrically driven centrifugal pump which gives a basic coldwater pressure of up to 150 p.s.i. The rotary cup burner will burn either oil or paraffin and is adjustable at any temperature up to 165° C. At maximum output, fuel consumption is approximately li gal. per hr.
