Nu-Calgon 4148-08 Gallon Cal-Shield Coil Surface Protector

Cal-Shield

A revolutionary product formulated with DuPont Teflon surface protector. Utilizes the recognized ability of Teflon to shield and protect finned cooling and heating coils. Cal-Shield is a synergistic liquid formulation based upon DuPont's Teflon fluroadditives.

It is specifically designed for application on air-cooled condensers, evaporator coils and other finned heating and cooling coils where it forms a micro-thin or molecular film made with Teflon^®. Once applied, Cal-Shield will shield and protect the coil from adverse conditions within the operating environment.

Special Features

• Formulated with DuPont Teflon^®.
• Is made with FDA approved ingredients.
• Ready-to-use formulation.
• Forms protective shield on coils.
• Reduces ability of dirt and grime to adhere to coil.
• Makes next cleaning easier.
• Extends life of coils operating in corrosive environments like salt air and food acids.
• Enables coil to perform at designed efficiency.

Application

Finned heat transfer coils like air-cooled condensers, evaporator coils, chiller coils and other similar air conditioning, refrigeration equipment are specifically designed to facilitate heat transfer between the coolant such as refrigerant or chilled water and ambient air. Conditions within the ambient air or environment such as greasy dirt and grim, nicotine, humidity, or corrosive salt air can affect the coil, causing the formation of efficiency-robbing deposits or even the degradation of the coil. These developments in turn result in a loss of capacity and efficiency and a corresponding increase in power costs.

For example, it is a typically accepted rule that a 2°F increase in condensing temperature brought on by the coil being fouled with greasy dirt and grim, results in a corresponding 1% increase in power costs and a 1% loss in capacity. Traditional cleaning of the coil with a coil cleaner removes most to all of these deposits, restoring lost capacity as well as operating efficiencies. Unfortunately, as the industry knows too well, the problem will return and cleaning will again be required.

Use of Cal-Shield following a cleaning with an approved cleaner like Nu-Brite, Alka-Brite, or Cal-Brite will allow the coil to operate for longer periods between cleaning. Once Cal-Shield is applied to the cleaned coil, it forms a protective shield made of Teflon^® that helps the coil resist the depositing of dirt and grime... moisture will bead up out; and run off. This enables the coil to perform more efficiently for a longer period of time. And, where coils are installed in aggressive environments such as salt air and food coolers, the Teflon will extend the coil's service life in this corrosive environment.
