Air Intakes

The air intakes are the first entry point for all air conditioning and should not be ignored. In most cases the amount of work required is minimal however no less important. The following should be followed when remediation of the air intakes commences.

A complete inspection should be performed by your maintenance staff and can be assisted by one of our Tri-Tec representatives.

The refurbishing of the air intake begins with the initial inspection to determine the scope of work required.
In most cases the inside of the air intake unit will require a thorough cleaning to remove rust, scale and dirt.
The substrate, once cleaned, will be ready for the application of our " NR 661 " rustgard which will convert any remaining rust on the metal portions of the tank or containment area. This is to be applied at a rate of 2 mm D.F.T. and sufficient curing time is required before application of our Tank Liner. Optimum curing conditions are @ 20 degrees C and relative humidity of 50% or lower.
Once the rustgard has cured (min12 hrs recommended) the tank liner can be applied. The 986-8 submersible primer finish (tank liner) can be applied at a rate of 5mls minimum D.F.T. and requires 2 coats for maximum protection.
Drying time between coats is approx 1hrs. And the introduction of humidity must wait for a minimum of 12 hrs to allow proper cure time.

Note: It is recommended that the above work be performed in the off hours and preferably on a weekend, starting on Friday at 5:00 pm to Sunday evening.
