Insitu® HVAC/R Coating Services
Extend equipment lifespan, REDUCE YOUR ENERGY CONSUMPTION.
High-performance anticorrosive coatings for air conditioning and refrigeration equipment applied in field and industrial facilities.
Three Types of Anticorrosive Shielding
Designed to maximize the service life and energy efficiency of your HVAC/R assets.
ES2 Technology (Ex)
Superior Resistance in Corrosive Areas
Insitu® ES2 is formulated with ES2 technology (stainless steel) to improve adhesion, moisture resistance, UV protection, and anticorrosive durability specifically engineered for equipment installed in corrosive environments.
Insitu® Black
Factory ElectroFin® Finish
This coating matches the color of our factory-applied ElectroFin® E-coat. Insitu® Black features a robust multi-polymer blend that preserves its appearance after years of exposure.
Insitu® Clear
Transparent Flexible Polymer Protection
Insitu® Clear is a water-based, flexible synthetic polymer anticorrosive coating with low VOC content and superior UV protection. Ideal when maintaining original unit cabinet color is desired.
Engineering Standard & Technical Performance
Insitu coatings are water-based and formulated with a high-performance flexible synthetic polymer matrix, engineered specifically to withstand severe environments without compromising heat transfer efficiency.

Professional 6-Stage Application Cycle
Our service features a controlled 6-stage process ensuring superior adhesion (5B rating per ASTM D3359).
Technical Note on Thickness
All our processes guarantee a uniform dry film thickness of 0.6 to 1.2 mils. This ensures complete protection without bridging between fins, maintaining original OEM airflow and heat transfer.
1. Disassembly
Careful unit preparation providing complete access to internal components and coils.
2. Pressure Washing
Thorough removal of dirt, oils, and surface contaminants using specialized cleaning agents.
3. Drying
Controlled technical drying process removing all residual surface moisture.
4. Coating Application
Uniform spray application using specialized field equipment and techniques.
5. Curing Time
Essential stage allowing the coating to dry and cure for safe handling of the unit.
6. Reassembly
Final assembly and inspection of the unit for commissioning or delivery.
