The failure or malfunction of many transformers or similar equipments can be directly attributed to the lack of proper control of the level of water vapour entering the equipment. It is essential, therefore, that a very low level of humidity is maintained in the air space in the top of the conservator tank to avoid deterioration of the insulating properties of the cooling medium.

Transformer Breathers provide an economic and efficient means of controlling the level of moisture entering the conservator tank during the change in volume of the cooling medium and/or airspace caused by temperature gradients.

All of our Transformer Breathers are filled with Envirogel, which is a self-indicating silica gel desiccant. This desiccant is orange/yellow in colour when active, but turns Green at 12% moisture level and ultimately very dark green at 80% saturation.
