Case Study: Heresite Coating of HVAC-R Coils for UK Food Production Facility
Heresite P-413 Coating of HVAC-R Coils for Resistance to Ammonia
Leading HVAC and Refrigeration Designer & Manufacturer supplying to the UK Food Industry
Scope of Work
Heresite Coating of all surfaces of 10-off 1350mm x 1625mm x 200mm Coils (Copper Tube / Aluminium Fins)
Ammonia laden atmosphere
Heresite P-413 Modified Baked Phenolic a high performance coating used principally for coil and radiator heat exchangers as well as other air and fume handling equipment fabricated of light gauge metals
Surface Preparation and Coating Application
The Coils were degreased, water rinsed and dried to remove oils, dirt, grease, wax and any other contamination that may interfere with coating adhesion.
The coating was applied by flooding with an air dry and intermediate bake between coats followed by a final
aesthetic spray coat to achieve a final dry film thickness of 35 to 50 microns prior to final bake and immediate despatch.
Heresite P-413 is the first HVAC-R coil and radiator coating to meet the ISO 20340 Standard for severe offshore marine environments. The corrosion resistance of Heresite significantly extends the service life of HVAC-R (Heating, Ventilation, Air Conditioning, and Refrigeration), and other heat transfer equipment.
In addition to marine and salt air environments, Heresite will withstand exposure to an extensive variety of high and low pH corrosive and chemical fumes and condensate. Because these products are efficient thermal conductors, applied at very thin films, HVAC-R and process equipment coil OEMs have indicated that thermal loss due to the presence of Heresite coating is <1%
