EVERPURE CONSERV 75E RO SYSTEM
FOR ESPRESSO EQUIPMENT
®
®
Traditional reverse osmosis provides high quality ingredient
water, but typically these systems are oversized for espresso
equipment, and many do not offer tailored blending for
precise water recipes.
The Pentair Everpure Conserv 75E High Efficiency Reverse Osmosis System is
a solution that brings the benefits of RO water to espresso applications while
addressing these concerns head on.
With a small physical footprint ideal for low-volume water-using equipment like espresso machines, the
Conserv’s proprietary high efficiency RO technology reduces the water sent to waste, which is a common
objection to conventional RO systems in espresso applications. The Everpure Conserv 75E System provides
a 50 percent water savings compared to conventional RO†. Designed specifically for espresso applications,
the Conserv 75E System features a blending valve to tailor mineral content for optimal taste and equipment
protection against scale and corrosion. This unique system is also ideal for combination applications, such as
espresso plus an ice maker, or espresso plus a hot water boiler.

KNOW WHAT’S IN YOUR WATER
Knowing what is in your water is as important as
knowing what is in your espresso. In addition to
H2O, water may contain minerals, chemical compounds
and/or contaminants which can alter taste and
damage equipment.
The most potentially harmful
contaminants are small particles,
iron, hardness minerals, chlorine
and chloramine disinfectant,
chloride, sulfate and nitrates.
EFFECTS OF CHLORINE: Chlorine
gas may be produced through the
thermal composition of chlorine or
chloramines disinfection methods
used in municipal water treatment.
In the moist and hot environment
of espresso equipment,
hydrochloric acid can be formed,
which creates conditions for
corrosion development. The
Everpure Conserv 75E RO System’s
pretreatment carbon filter removes
chlorine from the water, helping
to reduce the threat of corrosion
development on equipment.
EFFECTS OF TOTAL DISSOLVED
SOLIDS (TDS): Water supplies may
contain varying levels of dissolved
rocks and salts such as calcium,
magnesium, bicarbonates,
sulfates, chlorides and nitrates,
as well as trace metals such as
lead and aluminum. The TDS
content of source water supplies
can vary widely, but the national
U.S. average is estimated at about
300 milligrams per each liter of
water. That would translate about
1,140 milligrams per U.S. Gallon.
High levels of TDS cause scale
formation on espresso equipment
– the heat acts as a catalyst,
causing mineral compounds to
cling to dirt and fall out of solution
as scale which then can adhere
to the surfaces of the equipment.
The proprietary high efficiency RO
membrane built in to the Conserv
75E System removes TDS from the
water, significantly inhibiting scale
formation. Additionally, the RO
membrane reduces salt minerals
that can cause corrosion.
ESPRESSO EQUIPMENT WATER SPECIFICATIONS
Most espresso equipment manufacturers outline specific water quality requirements which end-users must
meet to ensure warranty compliance. The warranty is usually for a one-year period and is at risk of being
voided if the end-user’s water quality does not meet the recommended specification. Below is an example
of ideal water specifications for espresso applications, as recommended by Pentair. Developed with these in
mind, the Conserv 75E System can deliver a range of water qualities to fit virtually any espresso equipment
manufacturer’s requirements.

ESPRESSO’S THREE TOP WATER-RELATED PROBLEMS:
OFF
TASTE
METAL
CORROSION
When it comes to espresso,
ingredients are critical to
achieving the best tasting
product. Improper tasting water
and an imbalance of minerals can
alter flavor and aroma. Superiortasting drinks encourage repeat
business, and returning visitors
lead to increased sales and
profits. Installing a Conserv
75E System insures a delicious
espresso every time regardless
of the contaminants in the water
feeding the application.
MINERAL
SCALE
Corrosion is a chemical process
in which metals are eaten away,
causing components to rust
and disintegrate, eventually
causing costly equipment
to fail. Corrosion rates will
vary widely depending upon a
number of water quality-related
factors, such as acidity (low
pH), dissolved corrosive salts,
municipal disinfection used, and
operating temperature. Metal
corrosion is permanent and
progressive. When rust breaks
through the protective layer
of the metal, it cannot be fully
cleaned, removed or restored to
its original condition. This can
result in expensive repair visits
and ultimately shortens the life of
expensive equipment.
Mineral or lime scale is
formed when water contains a
combination of hard minerals
(calcium and magnesium),
carbonates and sulfates at
neutral or higher pH. Scale can
produce stress fractures and
pinholes in the boiler, as well as
cause drive probes and floats
to stick, resulting in under- or
over-filling of the water reservoir.
Scale can be removed with acid
cleaning, but this process is
harsh to all metal surfaces, and
can reduce the equipment’s
operating life.
In addition to the time and cost
of service calls, scale removal
can lead to equipment downtime,
negatively impacting sales.

A SOLUTION TO THESE PROBLEMS…
PENTAIR EVERPURE CONSERV 75E HIGH
EFFICIENCY REVERSE OSMOSIS SYSTEM
TRUE CORROSION PROTECTION.
EFFECTIVE SCALE INHIBITION.
REDUCED WATER WASTE.
The Conserv 75E System,
with a combination of technologies,
creates the right balance of minerals
to improve taste of water while
effectively inhibiting scale and
corrosion in espresso equipment.
Taste is refined through the removal of contaminants like chlorine by the carbon pre- and post treatment cartridges
in conjunction with the RO membrane. The RO membrane reduces scale by decreasing the TDS and hardness in
the water going into the espresso equipment. This same TDS reduction from the RO membrane, along with the
addition of minerals from the calcite feeder, also helps prevent corrosion in the espresso equipment. The final
piece of the Conserv 75E System is its unique blending feature, which allows for a custom water recipe through the
tailored blending of RO water and filtered water.
The combination of true corrosion and scale inhibition coupled with the
ability to customize mineral content differentiates the Conserv 75E System
from conventional RO systems. Coupled with less water waste than
conventional RO, this system is extremely versatile in addressing water
quality issues in espresso applications. This simple and reliable solution
helps end-users meet manufacturers’ target water specifications, helps
reduce premature and/or unexpected warranty claims, and increases
equipment life. It also increases customer satisfaction by creating
consistently optimal espresso.

CONVENTIONAL REVERSE OSMOSIS VS. CONSERV’S HIGH
EFFICIENCY REVERSE OSMOSIS: WHAT’S THE DIFFERENCE?
HOW DOES REVERSE OSMOSIS TREAT WATER? Reverse osmosis (RO) membranes separate water molecules
from dissolved minerals, salts and trace metals by forcing the water through a semi-permeable membrane.
The semi-permeable membrane contains tiny pores (10,000 times smaller than one micron) to effectively
reduce or remove the contaminants. This degree of filtration cannot be achieved with a carbon filter alone. A
typical reverse osmosis filtration system includes a carbon prefilter, RO membrane and a storage tank. Some
reverse osmosis systems include a carbon post filter for even greater taste improvement.
EFFICIENCY COMPARISON
In a high efficiency reverse osmosis system, water sent to drain is significantly less compared to a
conventional RO system. This means water savings, sewage savings, energy savings and sustainability.
