19 Anti Corrosion Treatment Special anti corrosion treatment of the heat exchanger provides 5 to 6 times greater resistance against acid rain and salt corrosion. The provision of rust proof steel sheet on the underside of the unit gives additional protection.

This allows the number of breakers and their capacities to remain small and simplifies wiring (for models of 10HP or less). Only one power supply Only brazed connections All flange and flare connections inside the unit have been replaced by brazing connections to ensure improved refrigerant containment. Also the connection of the outdoor in the main pipe is brazed.
