The Denver range of water softeners incorporates the latest technology to provide one of the most economical water softeners available in the UK.  Denver Plus 850 18L.  In the past water softeners worked on a electrical timer that would regenerate the system at a preset time every day.

Our latest Denver Water Softeners offer the latest state of the art metered controller. A metered system once initially set up to match the hardness of your tap water will then measure your actual water used.  The controller will then decide if it needs to regenerate the softener resin that day or it can wait until another day. 

New generation water softener system with an elegant cabinet provided with a sliding brine tank cover and electronic controller.
It includes an easy-to-program metered valve. System is composed by a GRP bottle with top and bottom distributors Isolation by-pass and hardness mixer included.
Noryl male connection (size depending on model). Brine valve included in the cabinet. and polyethylene cabinet.
