Measurements show no heat transfer reduction with WCS.
To adequately prepare and apply either of these products, you’ll be looking at 3 or more hours per coil of manpower. With WCS, you will be looking at 10 to 15 minutes max. per coil.
WCS can be applied right at your location, with no special equipment or training, for $20 to $100 per condenser coil depending on size.
Look at your salt-spray life data from your coating supplier. Chances are WCS meets or exceeds their testing times.
The general idea is to subject the specimen to salt fog for extended periods in a controlled environment. In the case of Coil Shield, treated coils were exposed to salt fog, then UV light accompanied by high temperatures, and an industrial atmosphere containing sulfur dioxide. Coil Shield was exposed for 1,500 hours with no corrosive damage to coil fins. The test was then continued until fins on untreated coils were falling off copper tubing. Coil Shield specimens were structurally intact at the end of this 4,000 hour test period.
Conditions vary widely. Winds, tides, and proximity to the ocean are all factors that determine corrosive rates. To help obtain a standard, accelerated weathering chambers are used to determine corrosion rates. In the field, it is recommended that Coil Shield be replaced every year under severe conditions, and less often under milder conditions.
Weatherproof Coil Shield is engineered to stop the corrosive effects of coastal salt fog on condenser coils.
Yes. Instant Powder Kegs is a concentrated, heavy-duty cleaner and is every bit as powerful as other, difficult to handle products.
Yes. We recommend the rinsing of coils after use of coil cleaners.
You can store a case of 30 gallons in a box that will fit on the corner of your desk. Most coil cleaners are over 90% water, and that takes up a lot of room that Instant Powder Kegs does not have to.
