Whether a coil coating is necessary hinges on the environment: salty air, kitchen grease, or aggressive chemicals can turn unprotected HVAC/R coils into short-lived liabilities.
Experts say modern HVAC equipment demands more careful cleaning methods, better chemical discipline, and closer attention to coil type and operating environment.
Dirty coils still hurt performance, raise operating pressures, and contribute to costly failures, but cleaning them improperly can create a whole new set of problems.
Master announced the nationwide addition of Hitachi residential HVAC products, marking a major expansion of its industry-leading portfolio and a strengthened partnership with Johnson Controls-Hitachi Air Conditioning.
ECM Technologies' ThermaClear conquers oil fouling by clearing the coil system from the inside, removing the oil barrier and super-lubricating the compressor.
The use of UV-C in HVAC systems has proven to be an effective way to minimize the threat of volatile organic compounds (VOCs), small particles, and other airborne pathogens commonly found in health care environments.
Microchannel coils are lightweight, offer better heat transfer, and use less refrigerant than traditional fin-and-tube coils; however, care must be taken when charging, as even a few ounces could reduce a systems’ performance, efficiency, and reliability.
