CRS 300ST

Eriez’ CRS Coolant Recycling Systems

Eriez’ CRS Fluid Recycling Systems are self-

contained coolant and fl uid management systems

capable of recycling any water-miscible fl uid to

its maximum potential. These units help minimize

or eliminate disposal, reduce usage of the fl uid

concentrate, and improve plant profi tability and

productivity. Systems ranging from small to large

feature low maintenance, unattended operation

and fast return on investment. Eriez’ CRS Fluid

Recycling System include:

• Separate dirty and clean tanks

• Automatic proportioner mixer –

coolant make up and control

• Oil removal device – free-fl oating,

non-emulsifi ed tramp oil

• Coalescer – tramp oil separator

• Liquid-from-liquid centrifuge – clean

coolant to < 0.5% emulsifi ed tramp oil

and 2-5 microns of particulate matter

• Pure water sources – reverse osmosis

systems or deionization systems

Custom confi gurations can include systems

that recycle a combination of both individual

machine tools and central coolant systems.

To facilitate the moving of fl uids to and from

the CRS recycling system, complete plant

distribution and return header systems with

pumping stations are also available.

CRS 120SS side-by-side

This modular, low-cost coolant recycling system

provides the basic requirements of fl uid recycling

with water-miscible coolant and cleaner products

that reject tramp oils. It has a convenient side-by-

side tank design and is equipped with a coalescer

to remove free and mechanically mixed tramp

oils. The CRS 120SS can be fi tted with a

high-speed centrifuge to address not only the

free-fl oating and mechanically mixed tramp oil,

but also remove partially emulsifi ed, bacteria-

feeding tramp oils.

Far left: The CRS 120ST with standard high-speed disc bowl centrifuge and stacked tank design is ideal when fl oor space is limited.

The CRS 300SS is a complete, full capability, single product coolant

recycling system for the medium-to-large-

sized metalworking plant operating with machine tools fi tted

with their own coolant sumps.

CRS 120ST stacked

This feature-packed system’s stacked tank design

reduces its foot-print and comes standard with

a high-speed centrifuge for complete recycling

of any metalworking coolant. The CRS 120ST’s

true high-speed centrifuge requires only one

pass through the system to remove tramp oils,

particulate matter and a substantial portion of

the bacterial population. Cleaning the fl uid to

this degree eliminates the need for expensive,

energy-intensive coolant pasteurization.

CRS 300ST stacked

The 300 series delivers an even larger centrifuge

for higher processing rates and allows greater

fl exibility for adding optional equipment. An

optional dual product design, referred to as the

CRS 200/200 ST, features two dirty and two

clean tanks for facilities using two different

metalworking fl uids.

CRS 300SS side-by-side

A complete, full capability, recycling system

for medium-to-large sized metalworking plants

equipped with machine tools using individual

coolant sumps. In its standard design, the CRS

300SS easily meets the recycling requirements

of facilities with up to 10,000 gallons of total

sump capacity.

For operations with greater fl ow rates or higher

processing capacities custom confi gurations

are also available from Eriez and HydroFlow,

including systems that recycle a combination

of both individual machine tools and central

coolant systems.

Solids-from-Liquid Centrifuges

Solids collect in individual machine tool sumps

and in large central systems. It’s important to

effi ciently remove these chips and fi nes as

they have a detrimental effect on coolant

performance and longevity as well as causing

lost production and headaches during removal.

Eriez’ Solids-from-Liquid Centrifuges

provide continuous MEDIA-FREE

fi ltration of both metallic and non-

metallic solids from industrial fl uids.

All Eriez’ Centrifuges are specifi cally

engineered for heavy-duty industrial

applications and will offer years

of trouble-free operation. Typical

solids-from-liquid centrifuges

applications include:

• Machining, grinding and sawing

• High-speed centrifuge pre-fi ltration

• Rolling and tube mills

• Water jet cutting

• De-scaling operations

• Wire drawing

• Parts washers

• Quench tanks

• UF pre-fi ltration

• Precious metals recovery

Filtering and Removing Solids

Solids-from-Liquid Centrifuges offer dependable, easy to maintain, media-free solutions to fi ltration problems. Imagine – no more fi lters to throw away!

Eriez’ Solids-from-Liquid Centrifuges provide continuous MEDIA-FREE fi ltration

Solids-from-Liquid Centrifuges are available

in either manually cleaned basket style

(complete with reusable liner) or fully automatic

self-cleaning designs to provide dependable,

easy to maintain, media-free fi ltration solutions.

Whether used on a single machine, a component

or as a supplement to a complete paper media

fi ltration/recycling system, the Solids-from-Liquid

Centrifuge can remove solids typically missed by

barrier fi ltration and reduces or eliminates costly

fi lter paper, bags and cartridges… all of which

require disposal.

The 50 gallon, 120 volt electric Sump Cleaner is small enough to fi t almost anywhere that fl oor space is at a premium.

All of the features of our standard sump cleaners are available in easy-to-use, virtually maintenance-free, air-venturi powered models.

Filtering and Removing Solids

The Sump Cleaner continues to be

the workhorse of the metalworking

industry

Sump Cleaners – Filtering and

Removing Solids

Eriez’ offers the widest selection of sump

cleaners in the industry. Solutions range from

inexpensive drum top cleaners to the industry’s

widely recognized sump cleaner. Manufactured

since 1974, these heavy-duty industrial wet/

dry vacuum fi ltration units clean virtually

any machine tool sump, tank, or pit quickly

and thoroughly.

Eriez’ Sump Cleaner rapidly removes fl uid, sludge

and chips from the sump, fi lters the sludge and

chips from the fl uid via the reusable integral fi lter

liner, and either returns the fi ltered fl uid to the

sump or transports the fl uid to the CRS Fluid

Recycling System. A polypropylene fi lter sleeve

fi lters to a nominal 50 microns. For fi ner fi ltration,

a single-use paper fi lter sleeve (to 20 microns

nominal) can be inserted into the chip basket.

The Sump Cleaner is fast! In just ten

minutes, a cylindrical grinder sump with

120 gallons of coolant and 700 pounds

of sludge can be completely cleaned,

coolant fi ltered and returned to the sump.

The reversible liquid vacuum is bigenough for toughjobs, yet small enough to fi t in your hand.

Magnetic Coolant Cleaners

Radial-design magnetic circuits extract

ferrous particles from the coolant

to help meet tolerances and

improve surface fi nish in

grinding and metal-cutting

operations. Smooth-faced

and extended-pole models

extend life of coolant, cutting

tools, grinding wheels and pumps.

Magnetic Conveyors

Eriez’ Tuf-Trac™ conveyors sit submersed in

the sump and continuously extract ferrous

turns. They’re supplied with magnets on

12-inch centers, supported by twin roller

chains that are powered by a shaft-mounted

motor reducer. The roller chain rides

on whisper-quiet Tuf-Trac engineered

polymer guide track that requires no

external lubrication. Conveyors feature

heavy-duty construction for years of

trouble-free operation.

Eriez’ Sump Cleaners are available in:

• 50 to 1,000 gallon designs

• Single and dual compartment confi gurations

• Push, tow or truck mounted options

• Air venturi, single phase, 3 phase electric

or liquid propane power

Two inexpensive solutions for individual

machines are Eriez’ drum top sump cleaner

and the reversible liquid vacuum. Both drum top

units draw up tramp oils, used oil and waste

coolants quickly and effi ciently.

Eriez’ drum top sump cleaner is a vacuum unit

that converts an open-top drum into a portable

machine tool sump cleaner. In addition to fl uids,

this powerful vacuum removes chips and fi nes

and is an economical alternative to a dedicated

sump cleaner. The compact reversible liquid

vacuum connects to a closed-head drum

and is used to remove lube or hydraulic oils

from reservoirs as well as many other fl uid

handling applications.

For machine shops that work predominantly

with ferrous metals, Eriez’ Magnetic Chip

Conveyors and Magnetic Coolant Cleaners

provide continuous removal of chips and swarf.

This magnetic equipment can be submersed

in the sump providing removal of large amounts

of ferrous materials prior to fi ltering.

The drum top sump cleaner converts an existing open top drum into a powerful machine tool cleaning system.

Removing Tramp Oil

Reducing tramp oil is a high priority for all

metalworking shops. Excess tramp oil leads to:

• Smoke, mist, and bacterial infestation

of the metalworking fl uids

• Adversely affect surface fi nish

• Reduces tool life and dimensional

tolerance control

• Skin irritations such as dermatitis

Partially emulsifi ed tramp oils in coolants are

the most dangerous and diffi cult to remove.

Removing this type of oil requires an Eriez’

high-speed centrifuge which delivers exceptionally

clean fl uid with tramp oil levels below 0.5%

and metallic solids in the 2 to 5 micron range.

Portable Tramp Oil Separator

This mobile centrifuge provides small metalworking

plants with true, high-speed centrifugation.

Eriez’ Portable Tramp Oil Separator recycles

fl uids at the sump by placing two hoses directly

into the machine sump removing free and

emulsifi ed tramp oils from water miscible

coolants and aqueous cleaners while the

machine tool continues to operate.

Eriez integrates larger, manually cleaned

high-speed centrifuges into its CRS Fluid

Recycling Systems. These systems are

complete fully palletized packages used

in conjunction with Sump Cleaners and

often with fl uid distribution systems.

Self-Cleaning Centrifuges

Typically, self-cleaning centrifuges are designed

for central systems pulling the fl uid, removing

tramp oils and small fi nes, and returning cleaned

fl uid to the central system. This type of centrifuge

package systems can be designed to handle any

combination of central systems and individual

machine tool recycling.

The high-speed disc bowl centrifuges are

available with either a manual clean,

solid-wall bowl or a self-desludging

two-part bowl design. The later

automatic, self-cleaning bowl is

preferred in high solids appli-

cations and on central system

equipment.

Self-cleaning high-speed

disc bowl centrifuges keep central systems running clean

and tramp oil free

Surface Oil Skimmers

The Surface Tramp Oil Belt Skimmer features an

oleophilic belt and a unique method of stripping

the separated oil from both sides of the belt

without contact with a stationary scraper. This

provides a great combination of performance

and long belt life.

The Standard Surface Tramp Oil

Belt Skimmer uses a similar “oil

loving” belt, but uses a more

compact scraper blade to strip

the separated oil from the

belt. This low maintenance

item can be equipped with a timer

so that the unit runs only when

the machine is idle and the tramp

oils have risen to the surface.

Portable Coalescer

Designed for plants with multiple machines

needing a simple, effective, low-cost tramp oil

separator able to be moved from machine to

machine. Eriez’ Portable Coalescer uses an

oleophilic (oil attracting) coalescing plate pack

media to remove oils effortlessly and effi ciently.

The unit is equipped with a standard electric

submersible pump, but can be upgraded with

an optional air pump or a heavy-duty electric

pump for deeper sumps. This portable coalescer

is effective with high temperature fl uids such as

cleaners as well. Consult the factory for larger

fl ow rate systems.

Tank Side Coalescer (TSC)

With a fl ow rate of 1.5 GPM, this small

inexpensive sump-side coalescing unit

allows oils to rise naturally by providing

a quiescent area not available in a

turbulent sump. The TSC comes

standard with a submersible pump

or with optional air pump.

The Portable Coalescer accelerates the process of removing tramp oils with its unique plate pack coalescing media.

The Standard and Deluxe Surface Oil Belt Skimmers can be used even in applications with limited access.

Portable Tramp Oil Separators remove even the peskiest tramp oils and can be easily moved on its mobile platform

Tank Side Coalescer – an effective yet economical unit.

The Drum Top Mixer is an economical, easy-to-use venturi mixer.

Controlling Concentration

Keeping tight control of the fl uid concentration

ensures fl uid never gets too lean or too rich. Eriez

complete line of mechanical concentrate mixers

meets the needs of all size metalworking shops.

These mixers eliminate manual fl uid mixing that

often results in imprecise concentration control.

Drum Top Mixer

A compact, easy-to-use venturi mixer for

combining water with coolant concentrates.

Water, jetting through the unit, creates a

vacuum that siphons concentrate from the

drum. A needle valve offers infi nite adjustment

across the mixture range of 2% to 10%. The

Drum Top Mixer is available in 3, 10, and

25 GPM versions and its all-metal construction

provides maximum durability.

The Proportioner is a water-driven,

positive displacement proportioner which

dispenses coolant on demand at the desired

concentration.

Proper concentration

control increases fl uid performance

and longevity

Eriez Proportioner

When greater accuracy and automatic

mixing are required, consider the Eriez

Proportioner. This automatic

unit is a water-driven, positive

displacement proportioner

dispensing coolant on

demand at the desired

concentration. The average fl ow rate

is 5 GPM with mixing ranges from 1% to

25%. Special units are also available for

highly alkaline parts washing fl uids.

The Eriez Proportioner provides consistent

concentration at all times despite varying

water pressures or fl uid levels in supply

containers. Because it is driven by the plant’s

water supply pressure, it can also supply properly

mixed fl uid through overhead piping to machine

tools without a booster pump.

Eriez’ Industrial Fluid Testers feature automatic temperature compensation.

Pure Water makes better coolant

Eriez advocates the use of pure water… as

pure water is key to excellent coolant, cleaner

performance and longevity.

Pure water sources include deionization and

reverse osmosis. Eriez can provide you with

a complete reverse osmosis system. Reverse

osmosis (RO) is a process that removes up to

98% of dissolved minerals, and virtually 100%

of colloidal and suspended matter. Compared

to other processes, it provides excellent quality

water at a low cost and does not require acids or

caustics for regeneration. RO systems are available

from 100 to more than 10,000 gallons per day.

Measurement Tools

Fluid maintenance and concentration control

programs must be checked on a regular

basis. Eriez offers a number of different style

refractometers to ensure accurate concentration.

The Refractometer is a simple yet rugged device

with a large, easy-to-read scale available in 0-10°

Brix or 0-32° Brix models. This portable meter

requires no batteries and quickly determines the

concentration level of:

• coolants and cleaners

• heat-treating fl uids

• water-based hydraulic fl uids

• plating baths

The temperature of certain fl uids can affect

the refractive index reading of the mix. In this

case, an automatic temperature compensating

refractometer is needed. Eriez’ temperature

compensated Industrial Fluid Testers have

large easy-to-read scales and are available

in two ranges: 0-20 Brix, and 0-30° Brix.

Eriez also offers an extremely accurate,

hand-held, digital Refractometer with an

easy to read LCD readout with 0-52 Brix.

Proper concentration control increases

fl uid performance and longevity.

Quickly determine coolant concentration with the Refractometer.
