Pre-filter cartridge: PURITY C50 Fresh (option 2 of 2)
Activated carbon is used in the PURITY C50 Fresh pre-filter as a filter medium to protect the
membrane in the PURITY C150 PROGUARD cartridge. With PURITY C50 Fresh as pre-filter, only one
mineralisation level can be achieved.
The type of pre-filter (PURITY C Quell ST or PURITY C50 Fresh) and the choice of possible
mineralisation level(s) is calculated by the App and determined by the local water quality.
Membrane cartridge: PURITY C150 PROGUARD
Removes 97% of all salts in the water, e.g., sodium chloride and sodium sulphate. The resulting water
is called permeate.
Mineralisation cartridge: PURITY C500 MinUp
Increases the carbonate hardness in the water by releasing calcium hydrogen carbonate into the
permeate. The resulting water is called filtrate. Depending on the local raw water quality, up to three
carbonate hardness levels can be selected: low, medium or high. From the choices available, the
coffee machine operator can select the degree of mineralisation that he likes to taste.
Post-filter cartridge: PURITY C50 Fresh
Uses activated carbon to avoid the risk of any potential taste and smell impairment.
Pump (non-electric)
A built-in non-electric pump is powered by the mains water pressure to pump the filtrate into the
downstream storage tank and releases the concentrate-effluent to the drain. A minimum mains
water pressure of 3 bar (dynamic) is required. In case of insufficient pressure, an electric booster
pump must be installed at any position between the mains water supply and the pressure reducer
that controls the inlet pressure.
Regardless of the mains pressure level, an electric booster pump can be installed to increase the
filtrate output of PROGUARD Coffee. The maximum inlet pressure must not exceed 8.6 bar. The
maximum pressure the RO can be operated with is 6 bar. A pre-installed pressure reducer reduces the
inlet pressure to the maximum permissible operating pressure of 6 bar. Pay attention to chapter 4.1:
Operating Specifications.

Filtrate output
Storage tank
Acts as a filtrate reservoir to provide sufficient filtrate when the coffee machine's water demand
exceeds the regular filtrate output of PROGUARD Coffee.
