Horst Ball from the Waschpark Treffen car wash centre already took action in the middle of the year in response to the worsening energy crisis and was one of WashTec's first customers to switch completely to cold water washing.

"I am glad that WashTec approached me with this innovative solution right at the beginning of the energy crisis. I acted quickly and had my self-service washing station converted to cold water washing immediately. This has already saved me lots of money since then – while colleagues anxiously follow the prices, I can concentrate fully on the business again."

Owner of „Waschpark Treffen“, Austria

The one-off investment of around £1,380 with the conversion kit from WashTec already pays for itself on average* after the first four months.

Full power even in cold water mode - this is how it works

The use of hot water can be traced back to times of low energy costs and the use of powder chemicals at the time. Modern washing chemicals are much more advanced in this respect. With AUWA, WashTec already offers high-quality washing and care programmes that enable familiar cleaning results to be achieved without the use of hot water.

WashTec car washes are now also able to guarantee the usual washing quality of the market leader exclusively with cold water washing. For this purpose, the hot water circuit is disconnected in the course of the conversion. This quick and cost-efficient solution is possible both for new systems and for retrofitting existing car washes in use in a straightforward and swift manner.
