Chiller Repairs: DON’T REPLACE IT – REPAIR IT!

chiller repairs - corrosion

In May of this year an HVAC customer of ours contacted us to look at a chiller that belonged to a brick & mortar customer of theirs. This chiller had developed a corrosion-caused hole in the bottom of the chill water barrel. These barrels are often painted at the factory with alkyd enamel primers without the molecular strength to act as an Under Insulation Corrosion Resistant Coating. The chilled water in these vessels are cooled down to temperatures in the low 40’s. Then, they are sent to a machine called an air handler. The air handler is where the chill water controls temperatures in large buildings of all types. The Evaporator – Cooler part of these chillers are insulated to protect the cold water being made from the warmer temperatures surrounding the machine. When the warm moist air finds its way to direct contact with the steel chiller barrel, condensation occurs. This is the perfect environment for the spreading of corrosion. The following is one of many chiller repairs PES has done.

PES 102 Power Metal Repair Fluid

Over the years, many of our customers have used PES 101 Power Metal Paste, PES 106 XF Power Metal Paste for faster cure, or PES 107 XL Power Metal Paste for longer usable pot life, metal filled polymeric products to act as an Irregular Shim. Because all of these products are 100% solids, with no solvent content and no shrink, they are often used underneath base plates to eliminate any voids and provide high compression strengths for equipment and machinery. PES 102 Power Metal Repair Fluid with it’s extremely high thixotropic properties, has long been used to fill pits in pump casings, impellers, and heat exchanger end covers.
