HereShield WB-506.
HereShield WB-506 by Heresite is at the center of our HVAC coating services. From residential condensers to large commercial rooftop units, DOAS systems, VRF equipment, and loose coils, Coolertech can coat units of any size. We handle disassembly, cleaning, preparation, spraying, and reassembly to protect the equipment inside and out.
Our coating capabilities
Small condensers. Large commercial units. Any size.
Our Pompano Beach facility and on-site services support equipment of any size. We plan access, handling, and the coating scope around each unit, including coils, cabinet interiors, bases, tubing, and other specified metal surfaces.
Equipment surfaces
Coating scopes can include accessible cabinet interiors, bases, tubing, and related metal components, with sensitive components protected during application.
Preparation and application
Equipment review, cleaning, surface preparation, masking, and coating application tailored to the substrate and manufacturer’s requirements.
Our coating process
From taking it apart to putting it back together.
We manage each stage so the surfaces behind the panels receive the attention they need.
- 01
Disassemble
Remove panels, fan assemblies, and other components as needed to reach the surfaces included in the coating scope.
- 02
Clean
Remove oils, dirt, and other contaminants, then rinse and dry the surfaces before coating preparation.
- 03
Prepare
Prepare surfaces for adhesion and mask electrical components, labels, connections, and other areas that must remain free of coating.
- 04
Spray
Apply HereShield to the specified coils and equipment surfaces, following the manufacturer’s application and drying requirements.
- 05
Reassemble
After the required drying time, remove masking, reinstall the components, and inspect the completed coating work.
