IntroductIon

The Everpure ENVI-RO™ Mineral Reduction System is a pre-

engineered, pre-assembled Reverse Osmosis (RO) system designed

to provide high purit y water for multiple applications, such as

premium espresso, coffee, blended beverages and steam, to name a

few. It combines a number of water treatment technologies into one

easy to install package. The system provides superior protection

against taste and odor causing contaminants while removing dir t,

par ticulates and dissolved solids that can foul or scale equipment.

Initial System Production

Water production depends on supply water pressure and temperature.

See PERFORMANCE section (page 8) for normalized production.

Influent Water characteristics

The following table lists the allowable operating range of various

water proper ties within which the ENVI-RO™ will function

properly.

Total Dissolved Solids (TDS)

0-1,000 ppm (0-1,000 mg/I)

pH

5-10

Chlorine

1

0-3 ppm (0-3 mg/I)

Chloramines

0-3 ppm (0-3 mg/I)

Turbidit y

0-1 NTU

Iron

0-1 ppm (0-1 mg/I)

Reverse osmosis membrane filter used in this system will be damaged by chlorine. An

activated carbon filter should be provided with this system to protect the reverse osmosis
membrane from chlorine attack. Influent chlorine should not exceed 3 mg/I.

the system consists of 5 major components:

2SR-BW Water Conditioning car tridge

1.

Dual-Head booster pump

2.

MR-600 Reverse Osmosis (RO) membrane car tridge.

3.

6-Gallon RO Water Storage Tank

4.

Control System with Power Supply

5.
The 2SR-BW Water Conditioning car tridge contains media that

reduces the scaling tendency of hard water minerals found in many

water supplies, extending RO membrane life.
The Dual-Head booster pump increases the inlet pressure to

maintain consistent permeate production, plus eliminates back-

pressure on the permeate output. This innovative approach to both

boosting and eliminating back-pressure allows for maximum system

ef ficiency.
The MR-600 RO membrane car tridge contains a semi-permeable

reverse osmosis membrane. Here, most dissolved impurities are

separated from the water and flushed down the drain. The water

that is able to pass through the membrane, which is very low in

dissolved impurities, is referred to as permeate, RO water, or

product water.
Once the RO water is produced, it is stored in the 6-Gallon RO Water

Storage Tank. This tank serves t wo key functions; 1) It acts as a

buffer bet ween the system and the connected equipment, providing

ample volumes of water instantaneously, 2) It reduces the on-off

cycling of the RO system, which produces bet ter qualit y water, and

prolongs the system’s life.

circuit) protected receptacle available for powering the system?
Is

3.

there adequate clearance and suppor t to install the unit

and permit access for maintenance? The total system weight

will vary based on model and storage tank selected. See

specification table for approximate operating weights.
