The MHI Q-Ton units are the latest CO² refrigerant high efficiency Hot Water Heat Pump technology. A similar installation completed at the start of the year is on track to provide a substantial in hot water energy costs from the previous gas installation.
There are not many harsher environments than in here in Cairns so longevity of the new units was a concern. The solution was an agreement with Aeris Environmental to train in the application of their corrosion protection to both the fins and panels of the new units to provide a longer lease of life in our environments.
The process involved stripping the units to expose the entire fin area, cleaning with a specifically made coil cleaner to remove the oil film common with the production of new coils then application of the blue Aeris corrosion protection plus. This was done in 2 coats to ensure the correct thickness to combat the environment the units will be subject to. The panels were also washed in the new cleaner then coated in a clear coat of the same corrosion protection to combat rust. This coil coating provides the extended protection without hindering the heat transfer capabilities of the coil, making it an excellent product to use.
Aeris has been tested to 30,000+ hours of salt spray test which is longer than other corrosive protection coatings in the market with the added benefit of in house VAE trained technicians providing ongoing support and annual inspections. VAE is now a Platinum partner of Aeris and can apply, service and provide 5 year warranty with annual inspections of the product.
