HAZARDOUS AREA / ATEX FEATURE
DSEAR ADHERENCE The importance of adherence to DSEAR cannot be overstated. Although thermal oil fires and explosions are not common, they do occur with avoidable regularity. Over a 10 year period, clients of insurer FM Global experienced 54 fires and explosions caused by thermal oil. In February, 2010, the thermal oil boiler at a wood processing plant in Northern Europe exploded, killing three people. While Thermal Fluid Solutions’ (TFS)
development of bespoke comprehensive continuous improvement plans enables clients to meet DSEAR standards, the explosion protection documents that form part of the plans also enable clients to prove their safety credentials to insurers and so reduce their premiums. One of the main elements of the
company’s work is the reconditioning of thermal oil in order to maintain appropriate flash points, offering an alternative to total fluid replacement. HTfluidfit can extend fluid life by a factor of at least 10, offering up to 70% of thermal fluid costs. Using a patented ‘flash evaporation’ technology, TFS’ rigs remove volatile organic compounds (VOCs) from the oil, returning it to a safe condition. The company also advises clients to
Solenoid valve temperature range extended
The existing ASCO 327 Series solenoid valve has now been made suitable for use in temperatures as low as -60°C, which has increased its application options in the process industry. The temperature extension means
that the solenoid valves now offer a reliable solution for arctic and polar conditions, which are increasingly common environments in oil & gas exploration. The ATEX certified solenoid valve
help guard against leaks and the consequent formation of explosive atmospheres with a diameter of up to 40m outside the thermal fluid system, via the fitting of spray-protected safe rings. DSEAR compliance requires ongoing
commitment to risk management. But with retained help from the right specialist provider, this commitment need not be onerous and can save a lot of money.

also offers CUTR, achieved through the inclusion of a Fluorosilicone (FVMQ) seal which provides exceptional temperature resistance. In combination with a higher spring force and a power consumption of 5.6/5.7 Watt AC/DC, this provides good sealing properties and a long life expectancy. The total temperature range of the
327 Series now covers -60°C up to +90°C. The new feature is available on a range of 327 Series valves.
