2x SPECTRUM Filter Activated Carbon

Pre-filtration Unit (decent / fair raw water conditions)

Reduction of water hardness
Controlled via LCD-display
Capacity: 30 Liters

Pre-treatment – Decarbonizer (poor / very poor raw water conditions):

Constant flushing
Controlled via LCD-display

UV-lamp

UV-lamp 14W, lifetime approx. 3000 hours

SPECTRUM Pure Cartridge

The SPECTRUM Pure Cartridge is specifically designed for the WSU 2 plus device range to produce ultrapure water with a conductivity > 18 MΩ.
The SPECTRUM Pure Cartridge is ready to use filled with a strongly acidic cation exchanger and a strong alkaline anion exchanging resin.

SPECTRUM Ultra Pure Cartridge:

The SPECTRUM Pure Cartridge is specifically designed for the WSU 2 plus device range to produce ultrapure water with a conductivity > 18 MΩ.
The SPECTRUM Pure Cartridge is ready to use filled with a strongly acidic cation exchanger and a strong alkaline anion exchanging resin. Both have a monodisperse particle size distribution based on a styrene divinylbenzene copolymer.

All water-wetted parts are made out of plastic or stainless steel, so that the WSU 2 plus can be operated with tap water as well as with deionized water.
