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.
Rust can be incredibly detrimental to the health of air conditioners !
In fact, corrosion is one of the primary causes of casing denigration and equipment failure here in Australia, especially on the coastline.

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 recommendingg CAT SYSTEMS for complete rust protection.”
