Pure water production from a new perspective

Waterdeioniser

NOWADEST® NF

NOWADEST® NF non-pressurised, cost-effective mixed-bed water deioniser

NOWADEST® NF water deionisers, which are designed for non-pressurised use, produce outstandingly high quality pure water simply and cost-effectively. These compact devices use ion exchange cartridges made of PE (polyethylene) and are simply connected to the mains water supply via a normal tap. Purified water must be allowed to flow out freely to avoid a build-up of pressure in the system, making this system ideal for those users who produce purified water prior to use for storage in bottles, carboys and other containers.

NF-series NOWADEST® water deionisers produce purified water with a conductivity of > 0.06m s/cm. Three different conductivity measuring instruments are available for purified water quality control. Along with the corresponding conductivity measuring device and water deionising cartridge, the NOWADEST® device is supplied complete with a tube set with an R¾" screw connector. Water deionisers are available in three different configurations (with an A-type, D-type or G-type conductivity measuring device). All devices are supplied with a conductivity measuring device as standard, to be screwed directly onto the cartridge. Conductivity measuring devices can also be supplied with a separate measuring head. In this case, all the electronic components are installed separately (e.g. by fixing to a wall). If this configuration is required, please specify in your order – in addition to the complete device – catalogue number 4010 for the "separate measuring head" option.

NOWADEST® NP

NOWADEST® NP pressure-resistant, high-performance mixed-bed water deioniser

The NOWADEST® NP pressure-resistant, mixed-bed water deionisers are the cost-effective alternative to the stainless steel ND-series water deionisers. In NP-series devices, the stainless steel water deionising cartridge holder has a PU (polyurethane) jacket. This protects the stainless steel inlet from physical shocks (e.g. when being taken away for regeneration) and adds to the design of the device. Easy handling and transportation is provided by the hand grips moulded into the collar of the cartridge.

The NOWADEST® NP can resist pressures of up to 10 bar, produces purified water with a conductivity of > 0.06m s/cm. and can be directly connected to outlet devices (e.g. the NOWADEST® pure water dispenser), filter units or pure water users. The device is supplied complete with the corresponding conductivity measuring instrument, a water deionising cartridge and a tube set with an R¾" screw connector.

Direct supply

The high capacity and flow rate of pressure-resistant NOWADEST® devices makes them ideal for the direct supply of water to apparatus such as dishwashers.

NOWADEST® ND

NOWADEST® ND pressure-resistant, high-performance mixed-bed water deioniser

The NOWADEST® ND pressure-resistant stainless steel devices have always occupied pole position in the range of mixed-bed water deionisers. They can withstand pressures of up to 10 bar and their high flow capacity and total performance level makes them the ideal choice for direct supply downstream to purified water users. These devices are especially suitable for use in combination with dishwashers, washing machines, analysis systems, climatic test cabinets and sterilising systems.

Mixed-bed NOWADEST® ND water deionisers supply purified water with a conductivity of >0.06 m s/cm. Water purity can also be controlled here by means of three different conductivity measuring instruments: of A, D or G-type. Along with the conductivity measuring instrument and corresponding water deionising cartridge, NOWADEST® ND-series devices are supplied complete with a tube set with an R¾" screw connector.
