BanHard Calcium Treatment Unit (CTU) - 16 Litre - 11,575 Litre Capacity 

BanHard Calcium Treatment Units are designed to eradicate limescale and improve the taste of incoming feed water. CTU's will treat water for a set capacity which is dependent on water conditions, once exhausted the CTU can be regenerated. Once a new BanHard CTU is purchased from us, you are then entitled to the regenerated CTU prices.

CTU Features

  • 2 Port Head with single inlet and single outlet (3/4" BSP connections)
  • Integral bypass (% bypass varies according to pressure and flow rate)
  • 11,575 litres capacity*

*Capacity is based on a temporary water hardness level of 200ppm. Incoming feed alkalinity levels also affect overall capacity.

Typical Applications Include:

  • Coffee machines
  • Water boilers
  • Combination ovens (requires a 3 port CTU, please call 0115 9460317 for details)
  • Vending equipment
  • Baking ovens
  • Bulk brewers

The 2 port head (2PDR) has a single inlet, single outlet and an integral bypass which allows a blend of untreated water to pass through, to improve taste, colour and odour, and increase capacity. Please note: % bypass varies according to pressure and flow rate.

This 16 litre unit can be regenerated for as little as £225.95 Inc. VAT and delivery. For regenerated units you must order over the phone by calling 0115 9460317. These are only available if you have an exhausted unit we can pick up. 

  • This system doesn't mix carbon with the resin, so regeneration becomes possible with positive results for the environment.
  • The carbon is located in the riser tube, which is the best place for polishing the water, giving maximum taste reduction.
  • The vessels use regenerated resin, which has a higher exchange capacity than new resin, so it will give maximum service time.
  • Fitted with 3/4" NRV male fitting on the inlet / outlet.
