5 Year Guarantee against corrosion and performance loss

Corrosion is widely accepted to be the main cause of early deterioration in heat exchanger coils, traditionally the most vulnerable part of air-side HVAC equipment.

If corrosion occurs without any corrective or preventative measures, performance can decrease by up to 80%.

Sealing the heat exchanger surfaces from the environment will either delay corrosive processes or prevent them from occurring in the first place, this being dependent upon the operating environment.

Blygold^® PoluAl is an anti-corrosion treatment consisting of a conversion layer followed by a polyurethane top coat. The operating temperature range is -50°C to 180°C. There is no loss of heat transfer performance and only a minimal change in air pressure drop.

The 'Blygold^®' treatment can be applied to cooling and DX coils, run around coils, heating coils and heat pipes. Areas of application may include:- industrial, commercial, medical, process, marine etc.

To counteract the possibility of corrosion it is current practice to specify either thicker fin material or higher specification material such as copper. With 'Blygold^®' there is significant potential for reducing the overall weight of the coil in addition to corrosion protection.
