allowing controllers to withstand corrosive and high-humidity environments better than standard equipment. Conformal coating acts as a barrier against moisture, fungus, dust, and other environmental contaminants, especially those particular to the water/wastewater and oil and gas industries. As a result, coated products have a longer lifespan and do not require expensive enclosures to house and protect them. Instead of being placed in NEMA-4 or 4X enclosures, in some cases Momentum controllers with conformal coating may be installed in less-expensive NEMA-1 or 2 enclosures. The control modules are protected against seven key environmental conditions: humidity, salt mist, fungus resistance, temperature resistance, dust, and mixed flowing gas and ISA.
