Pero degreaser help Tenable turn the screw on SED

Kenilworth, UK. March 2007: With the solvent emissions regulations (SER) set to come into force on 31 October 2007, turned parts specialist Tenable Screw Co Ltd has decided to take early measures to avoid potential fines by replacing a non-compliant Pero solvent degreasing machine with a new Pero V1 universal solvent degreaser from sole UK agent Kumi Solutions Ltd.

?This particular machine simply didn?t meet the emissions regulations set out in the forthcoming SER,? states Norman Runciman, facilities manager. ?We have a number of Pero machines already and they perform really well, so it was a fairly natural choice to acquire the Pero V1 from Kumi Solutions Ltd as a replacement.?

The forthcoming SER restricts emissions from organic solvents to limit worker exposure and protect health. Companies failing to comply with the emission limits set under the SER will face investigation and possible prosecution by the Health and Safety Executive. Firms may also face increasing compensation claims for associated health problems from affected employees, as well as hefty fines.

Pero Solvent systems reduce VOC emissions to below that of the incoming regulations and are in fact built to the tighter German laws 31 BImSchV and 2 BImSchV. All US and European emission regulations are surpassed. V Series machines from Pero work with the entire system under negative pressure (V standing for vacuum).

Another advantage considered attractive to Tenable Screw is that the machine can be used with all solvent types, hence the word ?universal? as its model suffix. In fact it is possible to swap from chlorinated hydrocarbons to hydrocarbons in a single day. Although Tenable Screw?s current focus is firmly on the former, Mr Runciman confirms that with constantly amended legislation, the move may prove fruitful in economic terms in future years.

Also supplied by Kumi Solutions, the SAFE-TAINER solvent system from SAFECHEM provides a direct interface with the Pero degreaser to ensure a fully SER-compliant system that is safe, leak- and spill-proof, and will not allow vapour to escape during transmission of the fluid from or to either the fresh solvent or used solvent tanks. Together with the Pero machine, this provides an all-round solution that ensures the health and safety of workers while adding to the efficiency of production.

Established in 1940, Tenable Screw Co Ltd has expanded from producing specialised screws by the hundred to the manufacture of high precision turned components by the million. Through a programme of continuous investment the company is today one of the largest producers in the UK with a full range of turning capacity available including 35 CNC machines, multi-spindle automatics, coil-fed automatics and rotary transfer machines based at three sites: London, Wiltshire and Coventry. Current annual turnover is in the region of £7.5 million.

Typical products range from tiny precision pins and sockets up to 32mm diameter components in all materials. The electronics industry is a specialty of Tenable Screw, machining shells and pins for a huge range of electrical connectors. Terminals and screw assemblies are also produced in their millions to suit most electrical or electronic applications. Batch sizes at this ISO 9002 accredited company range from 1000 up to millions. Other prominent industries served include automotive, aerospace and medical.

Scheduled for installation in January 2007, the Pero V1 will work at full tilt across a single day shift at the company?s Marlborough site in Wiltshire. It will be used to clean components ranging across Tenable Screw?s size range. Each basket can be loaded up to 80kg ? the V1 is able to process 6-10 basket loads per hour depending on selected cycle.

?This is a significant investment for us,? states Simon Schlaefli, managing director. ?The V1 was the most practical and suitable choice for our application available on the market. Whilst we have bought the machine in order to comply with the SER, ultimately our customers will benefit. Providing customers with good presentation of parts is undoubtedly an increasingly important factor. Today all customers expect components to be super clean.?
