Don't Let Corrosion Eat Away At Your Profits  

home :: services :: about :: contact

Success in today's highly competitive building management business depends upon high tenant occupancy, controlled expenses and most importantly - uninterrupted and trouble free operation. That means no unexpected shutdowns, no major equipment and service failures and no high cost emergency repairs. One of the most potentially destructive events that any building owner or operator can face is the weakening of their HVAC piping system due to advanced corrosion problems.

Predictive maintenance programs provide an answer to the conflicting demand to provide more reliable building services at lower cost and with limited personnel. Advanced corrosion of piping systems has become a very serious problem for many facility managers and engineers. There is a need for the best possible program for corrosion control and monitoring of critical HVAC piping services.

Corrosion monitoring is more complex than you think. Your HVAC piping system is susceptible to a number of different types of corrosion. There is no single measurement technique that will detect all of these various conditions.

Our recommendation is that you use several complementary techniques rather than rely on a single monitoring method. An effective corrosion monitoring program should include the following:

Comparative Features

Corrosion Coupons

Corrater Probe

Corrosometer Probe

Ultrasonics
