Calcium Treatment Units (CTUs)
APPLICATIONS
BENEFITS
Effective water treatment for all potable water applications where the use of sodium-based systems is inappropriate, notably:
CTUs improve water quality in several important ways:
• coffee machines (espresso, bulk brewers, pour-and-serve) • combination steam-convection ovens and baking ovens with water injection • hot water boilers for beverage making • drinks vending machines • ice-makers
• assures food grade standards of potability including removal of the scum which can occur in tea and vended drinks • removes heavy metals - lead, copper, mercury, etc - and chlorine, thus improving the taste, colour and odour of the treated water • prevents scale formation on metal surfaces • reduces maintenance costs and revenue loss through equipment breakdown • increases equipment life
OPERATION Temporary hardness salts - calcium carbonate and magnesium carbonate - and heavy metals are attracted to the CTU’s food grade resin beads and thus removed from the water supply. After softening, water exits the CTU via a silver-impregnated carbon filter incorporated in the central riser tube. This removes any remaining traces of organic matter and chlorine. Unlike some systems, the resin beads and activated carbon are not mixed together.

CANISTER EXCHANGE As CTUs cannot be regenerated on site, exhausted canisters need to be exchanged for fresh canisters at predetermined intervals. Frequency of changeover depends on the water hardness and volume of water used. European WaterCare provides a free water testing service to establish the capacity of each unit on site and obtains water meter readings where required to establish the appropriate exchange interval. Exchange can be undertaken by our service department using water hardness and unit capacity tracking of exchange requirements. For information on unit capacities at different levels of water hardness, please see seperate CTU Capacity Chart.
WARRANTY All CTU systems come with a lifetime warranty covering faulty manufacture. Installation of a CTU will eliminate scalerelated problems providing that the units are exchanged at the appropriate intervals.
PRODUCT RANGE European WaterCare offers a wide range of CTU systems to suit all applications. Single units are normally dedicated to a single item of equipment and are made in six standard sizes (5, 10, 15, 18, 23 and 30).
SERVICE BACK-UP All servicing is carried out by European WaterCare’s fully trained engineers and can be arranged on an annual contract. A telephone helpline is available for sizing advice and troubleshooting needs.
Special models are available to suit specific needs. However, due to the weight of units when wet and the practicalities of exchange, European WaterCare does not recommend canisters larger than 30 litres. Combi-oven water treatment: European WaterCare has developed systems which treat water for use in the steam generator, while the water which passes to the drain/quench is left untreated, This increases the service life of the unit.
CTU canisters can be linked together to provide the required quantity of treated water.
Duplex, triplex and multiplex systems suit treatment of water in large volumes or when used by more than one piece of equipment. Any number of canisters can be linked together to provide the required quantity of treated water. Units can be fitted with countdown meters set in accordance with water hardness and linked to an audible warning to indicate when the units are approaching exhaustion. All equipment to be treated by this system should be served by a plastic/alkathene ring main. FOOD GRADE ASSURANCE The ion exchange resin used in CTUs is specially prepared and purified to meet potable water requirements. It conforms with FDA (USA) regulations and has food grade approval in the UK via the Water Research Council.
