It’s like walking outside for miles during a blizzard in a coat with no boots, hat, or gloves. You will end up frostbitten and in trouble. Total protection is critical. The same goes for your HVAC unit. Many owners have their HVAC coils coated to extend the unit’s life, but
Corrosion testing on HVAC coatings can be conducted according to a number of standards, including ASTM-B117, ISO 9227, ISO 12944-6, and ISO 20340. Of these tests, the one we believe represents actual service environments most closely is ISO 12944-9 (formerly ISO 20340) vs. the more common ASTM B-117. ISO classifies
Heresite, a leader in the development of thin film corrosion resistant coatings, will launch ES-606, a spray-applied coating for HVAC-R coils as well as HVAC-R cabinets/components at the 2019 AHR Expo, to be held January 14 – 16, 2019 in Atlanta. ES-606 is designed for use as a standalone spray
Heresite, a leader in the development of thin film corrosion resistant coatings, recently completed a UV-C exposure test on its P-413 coating, both with and without a topcoat. The test was conducted in conjunction with Sanuvox Technologies laboratory. UV-C lights are used in many HVAC systems to sterilize HVAC coils
Coating extremely large HVAC-R units or coils can be difficult. Their size (both dimensions and weight) makes the units/coils difficult to move and many coating applicators find it difficult to thoroughly apply coatings to protect them from corrosive elements. A large HVAC-R unit/coil is clearly a big investment, which makes
Heresite, a leader in the development of thin film corrosion resistant coatings, has released a new whitepaper, Choosing an HVAC-R Coating for Marine Environments. The whitepaper was developed to answer common questions around evaluating the options for HVAC-R coil coatings in offshore and coastal marine as well as other corrosive
To further expand on Heresite’s expansive chemical resistance guide, P-413 coated steel, copper, and aluminum panels were placed in a municipal wastewater treatment facility to simulate sewage fumes. Panels were placed at the point where raw sewage is pumped into the facility and screened; this results in significant hydrogen sulfide
Heresite, a leader in the development of thin film corrosion resistant coatings, has now become the only company with a NSF/ANSI 51: Food Equipment Materials rated phenolic-epoxy for HVAC-R coils. The NSF rating establishes that Heresite’s P-413 coating has been shown to meet the requirements for materials and finishes used
For over 80 years, Heresite coatings have been used to protect HVAC-R equipment in the harshest environments. We’re proud of our history, and we’re proud to continue to offer products like P-413, which recently met the demanding offshore marine requirements of ISO 20340. These are tested, proven, real-world results. Unfortunately,
Heat transfer is an important consideration when selecting a protective coating for HVAC-R condensers or evaporators. A protective coating, when applied properly, can extend the life of HVAC-R coils by preventing corrosion with negligible impact on heat transfer. In 2017, we participated in a wind tunnel test for our P-413
