We are all accustomed to power washing our condenser coils and changing the air filters of our air-cooler package units in preparation for the air conditioning season…but that is not enough.

Air-cooler package units rely on outdoor air to cool the condenser coils which is then transferred to the evaporator coils.

Facility managers, building owners and mechanical contractors throughout the world are incorporating Protecall’s “field-applied coil coating” to this year’s start-up regimen.

MicroGuard^® is a glass-like coating that is proven to extend the useful-life of both evaporator and condenser coils, reduce the carbon footprint, and reduce energy consumption by 12% over the life of the equipment.

MicroGuard’s^® inorganic coating adds value to your units in 2 ways:

First, we protect the coils and reduce the rate of surface loss. With the higher efficiency ratings of today’s unit, square inches of coil surface area are critical to maintain efficiency ratings. Minor losses result in severe efficiency losses.

Second, we minimize the friction loss ratios through the coils. Again much of the efficiency ratings of a system are based on the design friction loss through both the condenser and evaporator coils. Through our premier coating product and nominal mil thickness, we offer one of the best surfaces to enhance smooth laminar airflow through the coils. This reduces fan horsepower requirements and fan amperage draw is a cube factor of horsepower requirement. Small static pressure drop changes can add up to substantial energy savings in fan horsepower. Engineering studies have shown that evaporator fan horsepower is typically 1/3 of the entire cooling system energy cost.

MicroGuard^® is a “Green Building” system that saves energy consumption by 12%, reduces carbon footprint and extends the useful life of your HVAC systems.
