Kelda Technology

Pioneers of water in air shower systems that save 50% in water and water heating.

Kelda Technology is a British clean tech business that develops water-in-air shower products that halve water usage and water heating costs through patented shower technology. Kelda Technology has adapted cutting edge automotive and aerospace technology to produce a revolutionary “water-in-air” shower system that halves water use without any loss in performance. Water is broken into droplets to form a comfortable spray which is accelerated using a globally patented jet-type nozzle. Not only does it halve water costs, but also halves associated heating costs. The Kelda shower system holds appeal for a wide range of sectors, including gym and leisure, hotels and accommodation providers, healthcare, and maritime – all industries where water efficiency is key. The product has completed in-market validation and commercial trials, is in manufacture and the company has already signed installation deals with some of the largest leisure operators in the UK and Latin America. Kelda Technology was recently chosen as one of the top 30 cleantech companies in the world at the New Energy Start-Up awards 2016 and was this week shortlisted by the UK Business Angels Association for Best Investment in a Disruptive Tech Business.
