Chiller modification packages are factory-integrated upgrades applied to proven OEM chiller platforms before shipment, eliminating the need to push critical weatherization, coating, insulation, and classified-area work into the field. Packages are developed around customer specifications and site conditions, and commonly include outdoor-rated NEMA 4/4X enclosures, Class I Division 2 electrical protection, corrosion-resistant coatings, insulation and metal jacketing, and customer-witnessed factory acceptance testing. We have modified chillers for refineries, chemical plants, mining and lithium facilities, coastal and corrosive environments, process cooling applications, and industrial equipment yards requiring classified-area compliance.
