“Rust can be incredibly detrimental to the health of air-conditioning systems !”

In fact, corrosion is one of the primary causes of casing denigration and equipment failure here in Australia, especially on the coastline.


CAT Rust Protection Systems can provide an effective and affordable anti-corrosion solution for any size residential and commercial air-conditioners.  This advanced technology has been tried and proven in Australian conditions and is the preferred choice of many air-conditioning professionals.

This is what our customers say….

“During the last 6 years or so we have installed well over 100 CAT SYSTEM electronic rust control units on the high rise outside air-conditioners. These air-conditioners are exposed to salt air 24 hours a day. In all that time there has been only one failure, the air-conditioner rusted because CAT SYSTEM connection was not switched on!

CAT Systems Australia are most professional to deal with, providing excellent service and marketing a high-quality unit with a most satisfactory performance result. I have no hesitation in recommending CAT SYSTEMS for complete rust protection.”

With a CAT Air-Conditioner Electronic Rust Protection System Installed, an anti-corrosion barrier is set in place and used to protect casing and internal surfaces within the air-conditioning equipment. It can vastly extend the life of any air-conditioning system, no matter what type of system that may happen to be.
