Corrosion Inhibitor for Dry Layup of Cooling Systems

Complete Corrosion Protection:
A combination of inhibitors protects both ferrous and non ferrous metals.

Energy Saving:
Prevents corrosion that reduces heat transfer and destroys piping.

CWT-LAYUP is a highly effective corrosion inhibitor system. It is a liquid blend of filming organic inhibitors. They form a protective film on clean metal surfaces. The film protects the piping during the off season against corrosion. CWT-LAYUP will not clean or prevent corrosion already occurring on system piping, but it will help prevent it from worsening.

Dosage and Testing:
A sufficient amount of CWT-LAYUP depends on the water capacity of the system. Add 1-2 gallons of CWT-LAYUP for each 1000 gallons of water in the system. Your Patriot representative will recommend the proper dosage for your system and operating conditions.

Add the required quantity of CWT-LAYUP to the system at any point that will allow for adequate mixing of product with system water. Typically, this can be done directly to the tower sump. Surfaces of the cooling system should be clean and free of biological fouling before treatment. Once product is added, circulate system for 24 hours. Then drain system completely. The protective film will remain to provide corrosion protection.

Regular service calls can be made by your representative. All recommendations and adjustments for correct use will be discussed with operating personnel at this time.
