Protection against downtime

BOC Edwards’ vacuum pump, the 18B4, has been upgraded with additional features to enable easier maintenance and operation. The new version, 18B4B, includes a clean out port and optional oil level and temperature measurement sensors. These new features aim to reduce cost of ownership by simplifying maintenance procedures and minimising the downtime that can occur as a result of low oil levels or loss of heaters. Oil is vaporised at a temperature of 200-250C in the boiler that sits at the foot of the pump.
