cleaning large components. The AS-150 can take a load of 800kg and will accommodate components measuring 900mm high by 1.4m across the diagonal or diameter. The single-stage, spray wash machine offers a large processing volume for the capital investment. In addition to applications in refurbishment and overhaul, the AS-150 is suited to inter-process cleaning in production environments, such as batch degreasing of machined components and preparing fabrications for welding. A major advantage is that the cleaning medium is detergent dissolved in water heated to 50-75°C, delivered at 400 litres/ min and 4-bar pressure through rotating spray pipes. Problems associated with using and disposing of hazardous solvents are therefore avoided. In normal operation, the door at the front is lowered with the assistance of two gas springs, one or more components are placed in the work chamber, the door is closed, cycle time and temperature parameters are set on the control and the automatic cycle is started. An optional lance with its own multi impeller pump delivering 10 bar can be connected directly to the 900 litre tank. This allows the operator, with the machine door open, to manually spray-wash obstinate areas of soil on a component, either before or after the automatic process. Alternatively, the machine can be used as a manual spray booth, without any automatic cleaning. Apart from the galvanized steel work table, the machine is constructed almost entirely from stainless steel, even the integral 500-micron filter. The installed weight of the machine is nearly one tonne. Acoustic and thermal insulation ensure a good working environment for the operator. Optional accessories include a steam extraction fan, automatic refill, oil skimmer or separator, and a detergent dosing unit. A smaller machine in the same series is also available, designated AS-100, for cleaning components up to 950mm across by 700mm high, and weighing a maximum of half a tonne.

Batoyle Freedom Group, UK, is an independent lubricant manufacturing com- pany founded in 1875. The company’s AX24 lubricant promotes the quick and easy connection of sealing joints on a wide variety of piping materials. Its main benefit is its suitability for use within pipework systems designed to carry potable water. Developed at the Batoyle Freedom Group’s in-house laboratories more than ten years ago, AX24 is a fully synthetic water-based compound based on complex mixtures of thickeners and esters. Key to the continued success of AX24 is its very high levels of lubricity, which enables easy coupling of push fit sealing joints. AX24 is easy to apply onto either wet or dry pipe surfaces. Being completely water soluble, it is rapidly flushed away from the joint once the pipe is in use – a characteristic that ensures pipes can be easily disinfected by techniques such as chlorination. AX24 is formally approved under the WRAS (Water Regulations Advisory Scheme), as a pipe jointing compound for use in contact with potable water. It exhibits low orders

of both acute oral and dermal toxicity and incorporates a broad spectrum biocide/ fungicide as an in-can preservative to enhance shelf life. The lubricant is compatible with a wide variety of piping materials, including metal, ceramic and plastic, as well as pipe fitting accessories including common gasket materials such as nitrile rubber and neoprene. AX24 is available in 500ml, 1L, 5L, 25L and 205L containers. Lubricants manufactured by the Batoyle Freedom Group are exported to more than 50 countries world wide, through a network

of local agents and distributors. Batoyle Freedom Group – UK Fax : +44 1484 461998 Email : bfginformation@aol.com Website : www.batoyle.co.uk
