Frost/Freeze Protection for Macsep Oil Water Separators

Macsep manufactures and distributes a range of oil water separators primarily for power industry and petroleum industry applications but also for other industries where high specification and/or high performance is required.

A recent development for Macsep’s range of small oil water separators has been an option for frost and freeze protection. A standard unit is modified by adding thermostatically controlled heat tracing, fire resistant close cell foam insulation all enclosed by an outer cladding of 304/316 stainless steel.

Not only do these additions protect against frost or freezing of the water in the oil water separator, pump and associated pipework but they also maintain the contents of the oil water separator above a minimum set temperature maintaining the separation performance of the unit.
