Vacuum breakers should be installed wherever vacuum is created in pipelines or other equipment to ensure trouble free operation such as heating coils for uninterrupted production and elimination of freezing

The units are factory set to operate at 5 inHg (mercury) (0.17 bar.g) vacuum but can easily be reset to suit plant conditions.

Other applications include: unit heaters, cooking kettles, blast coils, and air-conditioning equipment.
