Boiler and Boiler Feed Piping

Boilers and piping used to generate and transfer steam and hot water for heating operate under pressure. Rupture disks from ZOOK ensure that the systems maintain safe operating pressure levels in boilers and connected steam and condensate piping.

Air Conditioners and Refrigeration Systems

Air conditioning and refrigeration systems utilize refrigerants under high pressure. ZOOK rupture disks provide over-pressure relief if the system exceeds acceptable operating pressures. ZOOK rupture disks in series with safety relief valves help provide zero process leakage to reduce fugitive emissions.

Cooling Towers & Chillers

Cooling towers are large scale heat exchangers used to cool and condense steam after it passes through a turbine as it returns back to the boiler. Installation of ZOOK rupture disks ensure that the system does not exceed preset pressure limits.


There are many other pressure relief applications we provide to the HVAC. Please contact ZOOK for applications not listed.
