Insitu® Spray Applied Coating System

Insitu® – The Ultimate Field-Applied Corrosion Protection for Evaporator and Condenser Coils

The best non-factory applied protection available are Insitu® Spray Applied Coatings. These unique and proprietary coating processes offers today’s HVAC/R systems the highest level of field-applied corrosion resistance. A system properly coated with an Insitu® Spray Applied Coating can withstand harsh, corrosive environments to provide long-lasting and cost-effective protection.

An Insitu® Spray Applied Coating protective coating will protect your HVAC/R equipment for many years, providing you with a system that operates with optimal performance and efficiency over its lifetime.

When it comes to protecting expensive HVAC/R equipment, coils and systems, there are no better non-factory applied protective coating than Insitu® Spray Applied Coatings. Have confidence these products have the highest quality standards and pass the most arduous industry tests ensuring top performance you can trust.

Do Coil Coatings Decrease System Efficiency?


Throughout the HVAC/R industry, there is some talk about protective coatings degrading the true performance and efficiency of the heat transfer coils, whether evaporator (most susceptible to corrosion) or condenser.

While this case can be made, many engineers and OEMs advise that a protective coating is necessary and recommended as any loss in heat transfer efficiency upon initial installation is soon eclipsed by corrosion degrading the coils in non-coated air conditioning, refrigeration or heat pump systems. This is especially true in corrosive environments where the extended life of coated systems makes better sense when total cost of ownership is considered.

And Insitu® Spray Applied Coatings are especially formulated to deliver maximum protection with a minimally thick film does not plug cooling fins or air passages, and is:

  • Flexible
  • Impact Resistant
  • UV Resistant

Applications Ideally Suited for Insitu®

  • Heat exchanger coils (water, condenser, evaporator, DX)
  • Mini-splits
  • Packaged Rooftops
  • Condensing Units
  • Modular Air-Handlers
  • Air-Cooled Chillers
  • Interior & Exterior HVAC cabinets and copper piping

Protection When You Need It

The two main causes for HVAC/R equipment failure are mechanical and corrosion. Corrosion leads to lower operating efficiency, shorter system life and an increase in the total cost of ownership. Insitu® Spray Applied Coatings allow placing corrosion protection where it’s needed most – the bottom line.

Application Ease

Insitu® Spray Applied Coatings can be applied upon system installation or later, although at installation is most recommended. Simply follow the application procedures that only require a minimum of training and equipment.
