AFRF Dry-Type Transformer Air Coolers
STE Technic's patented AFRF coolers enable dry-type transformers to operate in a fully enclosed housing, completely isolated from the external environment, and reach up to IP55 protection class. Without requiring any external power supply, transformers can be safely operated in harsh environments such as marine, offshore, mining, and tropical regions. This is a self-operating and independent system.
STE Technic AFRF Coolers can be manufactured from stainless steel, copper, or aluminum materials. During the design process of AFRF coolers, factors such as transformer losses, ambient temperature, corrosion class requirements, and environmental conditions should be taken into account.
