RA Tech UK

RA Tech UK Ltd, a company founded in 2014 by experienced and respected plumber Russell Armstrong (Member of the Chartered Institute of Plumbing and Heating Engineering – CiPHE), is the inventor and developer of the hotun dry drap tundish.

Russell’s long experience in the building industry has led him to understand the practical problems that installers and tradespeople face when driven by the demands of certain regulations. The introduction of new products to meet those regulations is a challenge in itself and to devise a simple and effective way to solve a problem is what Russell set out to do.

Having come up with the idea of hotun, he formed his company, with fellow director (and wife) Ally Armstrong, RA Tech UK Ltd. He has invested in patenting the product, testing it fully, and getting it approved by all relevant industry bodies. A major investment in design, development, testing & tooling and then, commissioning all manufacturing to local ISO9000 companies. This means that hotun can be specified and installed with confidence, and is offered with a 5-year warranty.
