Transformer Breathers

TransformaDry Desiccant Breathers allow air-flow between a sealed space and the outer atmosphere, whilst at the same time preventing moisture ingress into that sealed space.

They are widely used in electricity transmission and distribution networks, where they are fitted to sub-stations and transformers. They are also used as tank vent dryers for fuel and solvent tanks.

Our desiccant breathers use TG-3: a unique silica gel, which changes colour as it transitions from; Dry, to Damp, to Saturated.

We’ve developed this 3-step ‘Traffic-Light’ chemistry to remove the guesswork from setting breather replacement intervals, because unlike other gels (which have basic ‘on’ or ‘off’ colours), the mid-life point with TG-3 is clearly defined – and this gives you ample forewarning of when replacement is needed. It’s as simple as: Ready, Steady, Go !

We believe that TransformaDry DESICCANT BREATHERS are the easiest-to-use product in the marketplace – why not try one today ?
