Pacific Water/Water Non-Storage Calorifiers


GMS Pacific Non-Storage Calorifier for use in water/water applications

The Pacific PA range of water to water calorifiers are mostly used in heating / cooling systems to transfer heat from one independent circuit to another. The majority of applications are for generating LTHW (82/71°C) from MTHW and HTHW although the calorifiers can be used for oils and other liquids if required. Other applications may also arise with different water temperatures and materials of construction. The technical team at GMS Thermal Products have many years' of experience of calorifier and heat exchanger design - we can offer special units, designed for the job, if required.

PA Configurations available: Horizontal and Vertical. Multiple units in series may be offered for certain temperature conditions.

PA Construction: All units are of robust construction. Tube bundles have substantial supports and baffles and are withdrawable for inspection.
