SUPPORT AND DOCUMENTS REQUEST A CUSTOM QUOTE
Heresite™ is one of the most respected companies in the protective coating business. They have developed their first protective coating in 1954, and since then have continuously improved their products, making them a staple of high-quality protective HVAC coating.
For almost 7 decades Heresite™ has produced corrosion protection coating that delivers high performance. Their coatings have superior chemical resistance properties and are the top choice for harsh environments.
Rahn Industries has been a Heresite™ certified licensee since 2015, and provides immersion and spray coatings options to our customers. We also can disassemble and reassemble HVAC equipment to apply coating inside and out.
P-413 Baked Phenolic Epoxy
The P-413 is a thin high performance protective coating used mainly for ac coils radiator heat exchangers. The corrosion resistance of this coating significantly extends the s life of HVAC unit. It withstands marine and salt air environments, exposure to an extensive variety of high and low pH corrosive and chemical fumes and condensate, while still being and excellent thermal conductor.
This product is recommended for use in light gage metal, especially products made of aluminum, stainless, copper, and carbon steel.
The protective coating is applied by an immersion process (also known as dip & bake) where the coil/equipment is immersed in the protective coating, and then after being removed from the solution it is baked in an oven to cure. This process produces a very durable coating that provided inside and outside protection for your coil/equipment.
ES-606 Epoxy-Silane
The ES-606 is a high-performance, robust spray-applied coating used to protect heat transfer equipment and components like coils and cabinets. It is an excellent choice when a full-immersion product like the P-413 cannot be used.
This product is applied directly to the metal and has excellent corrosion, humidity, and UV resistance, along with good adhesion to ferrous and non-ferrous metals. It can be used in internal and external surfaces of HVAC coils and equipment.
