Description
Product Introduction
The Anti-Corrosion Coated Evaporator Coil is designed for commercial refrigeration and cooling equipment operating in humid or demanding environments. A protective anti-corrosion coating is applied to the coil surface to help resist rust, oxidation, and environmental damage.
With excellent heat transfer performance and enhanced durability, the evaporator coil helps maintain efficient cooling while reducing maintenance requirements. It is widely used in display refrigerators, beverage coolers, freezers, cold rooms, and other commercial refrigeration systems.
Corrosion Resistant Coil Coatings
Extend the life of your HVAC system with one of our coating options
Fins on evaporator and condenser coils are made using aluminum, which is relatively corrosion resistant even without any type of coating. However, the harsh conditions under which Specific Systems units are placed often requires additional protection. In order to meet these needs, Specific Systems makes available numerous coil coating options, each with unique and energy saving traits.
Further, any of our systems can be ordered with copper fins in addition to the copper tubes, providing greater resistance to corrosive contaminants.
Our coating starts with a seven-stage cathodically-applied epoxy that is proven to withstand aggressive industrial atmospheres. It is then topped with Heresite VR-514, the industry standard in air-dried phenolic coatings. The combination of the flexible e-coat with the Heresite spray combines to form a nearly impenetrable barrier that resists cracking while still holding up to salt-spray in coastal/offshore areas.
E-Coat (or electrocoating), as applied by Electrofin, is an environmentally friendly wet- paint process used on many products, including as a primer on many new vehicles. E-coat resists chipping and will extend the life of coils, E-Coat is also the thinnest coating, with applications computer-controlled to between 0.8 and 1.2 mils. Using a proprietary complete immersion process, Electrofin ensures complete coverage without any fin- bridging (up to 30 fpi/16 rows).
