Cost Savings & Specifying ElectroFin® E-Coat
In mild, non-coastal environments, aluminum-fin coils pre-coated with an epoxy offer a bit more protection than an uncoated coil and can be more economical than copper or e-coated coils. Coatings suppliers sometimes hedge on how much their product adds to the service life of equipment, saying their coating extends the life of a coil “several times compared to an uncoated coil.” ElectroFin® E-Coat is specifically formulated and optimized to lengthen equipment service life by four to five times and have less than 1% impact on the thermal efficiency of the coils it protects.
Major HVAC/R OEMs approve the use of ElectroFin® E-Coat and many OEMs approve of Insitu® Spray Applied Coating for their systems. ElectroFin® E-Coat and Insitu® Spray Applied Coating deliver other benefits as well:
- It can help to reduce energy consumption and can help new construction projects attain LEED certification by the U.S. Green Building Council.
- In densely populated urban areas, vehicle exhaust trapped by high-rise buildings can create a corrosive micro-environment.
HVAC Coil Coatings – Pay Now or Pay Later…and Perhaps Much More
SWAAT testing was performed on a copper tube aluminum plate fin (RTPF) condenser manufactured by Modine. A total of three identical condensers were tested:
- Bare, un-coated condenser for base-line comparisons
- Cathodic epoxy coated condenser having an additional UV coating
- Immersed/sprayed modified-phenolic coated condenser
Specifying ElectroFin® E-Coat
ElectroFin® E-Coat is the number-one choice of OEMs for heat transfer coil corrosion protection. All major OEM brands offer it for their customers, who value its extra protection and cooling efficiency. Typically, the inclusion of ElectroFin® E-Coat in the manufacturing stage adds about two weeks to the order/delivery cycle.
Key to keeping your company’s construction or renovation timetables on schedule is reaching out to your general contractor early on. Have your contractor break out the cost of adding ElectroFin® E-Coat to its overall bid. Some contractors may be reluctant to do so because they believe that including the cost of any factory-applied coating (even separately) will make their bid less competitive.
