3. The ongoing chemical corrosion of uncoated copper tube/aluminum fin, or copper tube/copper fin coils, typically results in a minimum of up to 55% loss in equipment operating efficiency as well as the obvious equated rise in electrical power costs.

4. Coated coils can save as much as 50% or more in extremely severe conditions, in electrical power costs savings alone.

5. The commensurate rise in maintenance, repair, and replacements costs must be added to the rise in electrical power consumption and subsequent increase in operating costs to provide the complete cost effectiveness of applying coatings to standard OEM copper tube and aluminum fin coils of uncoated equipment.

Cost Consideration vs Return on investment

The coating process pricing is dependent upon project size, installation location (shipping destination of coated equipment), type of equipment (ease of accessibility), what type of coating product is required to coat the system and components required to be coated.

When considering cost, one should likewise address the subsequent costs adopted when choosing NOT to coat heat transfer coils upon initial installation. The "Return on the initial Investment” of coating heat transfer coils, no matter what the equipment size, "PAYBACK" is typically well within two (2) years from initial installation. Compare this "PAYBACK" to the financial losses in terms of energy usage, service repair labor, equipment "down-time”, as well as coil and/or compressor replacement expense during the 3 to 7 year life of unprotected equipment. Typical Life Cycle” of Perfect Coat PC-2000 coated equipment can be as much as 3 times greater than that of uncoated/unprotected equipment, depending upon the severity of the corrosion atmosphere at location and proper/timely preventive maintenance/cleanings.

1. The threat of corrosion to HVAC/R coils is the most serious to installations 10-15 miles from the coastlines and much closer to other environmentally concerned locations. PC-2000 works excellent for Waste Water Plants and other similar facilities. Florida is basically a peninsula stuck out into the ocean

2. Corrosion and subsequent deterioration at the "heat transfer point” of contact, where the copper refrigerant tubes join the originally manufactured tightly "coined" edge of the aluminum fin, is the critical area where loss of heat transfer escalates the energy use and the cost of operation rises exponentially.


Corrosion Solutions offers the most detailed applications in the industry using what we see and believe to be the best materials available today.

Our coil coating material is an Heresite Protective Coatings lnc product called Perfect Coat PC-2000, an air dried Phenolic coating that has all the properties to make PC-2000 one of the most long lasting, most durable coating available.
