Transformer Breathers

The failure or malfunction of many transformers or similar equipment can be directly attributed to the lack of proper control of the level of water vapour entering the equipment.

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.

Valved Reservoir Breathers

Many fluids, semi-solids and powders can be seriously contaminated by moisture and process by products. Most materials stored in tanks or drums which are either located in the open and vented to atmosphere or are located in the process area can be affected by materials used in the same area.

We offer a range of valved reservoir breathers to provide a high level of protection to a wide range of materials.



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. Other types of desiccant are also available.
