Clean coolant where the shop needs it

The optional CRS distributes clean coolant from C.R.O.S.S. through facility piping. Dirty coolant is normally collected from individual reservoirs with a Green Machine or another portable transfer device and delivered to the system for processing. A configured dirty-coolant return network can also be engineered where a fully piped arrangement is required.

Clean coolant is distributed under pressureThe CRS pumps clean coolant through the facility at 35 to 40 PSI for convenient access across the shop.

Configuration fit

When central clean-coolant distribution fits

A CRS can reduce manual clean-coolant transport when the facility layout supports distribution piping. Portable or hybrid configurations remain available where piping is not practical.

Central fits when
01New construction or an existing clean-coolant distribution network
02Enough machines in fixed positions to justify the runs
03Machines on a common fluid family
04Clean coolant is needed at multiple points across the shop
Batch or hybrid fits when
05Facility piping is not practical for the current layoutBatch configuration →
06Central piping serves the main production cells, while portable transfer serves remote or secondary machinesHybrid deployment →
07Too few machines, or you want to move machines without re-pipingBatch deployment →
Planning consideration

Central distribution requires facility piping for clean coolant. The layout is planned around required delivery points and operating pressure. Batch or hybrid configurations provide alternatives where a full clean-coolant distribution network is not justified.

How the system operates

Collect dirty coolant and distribute clean coolant

In the standard workflow, portable equipment delivers dirty coolant to C.R.O.S.S. for processing. The optional CRS pumps clean coolant through facility piping, while a configured dirty-coolant return network can be engineered for facilities that require a fully piped arrangement.

Portable collection delivers dirty coolant to C.R.O.S.S., while the optional CRS distributes clean coolant to the shop.

Dirty coolant is collected on a planned schedule. Clean coolant remains available immediately rather than requiring operators to wait for each delivered batch to finish processing.

System applications

Coolant recovery systems by operating environment

Machine shops use C.R.O.S.S. to maintain a central supply of clean coolant. Tube and steel mills use TMCRS for real-time filtration engineered around the required mill flow.

Tube Mill Coolant Recovery System · permanently integrated

The real-time recovery system for tube and steel mills. Hydrocyclone, magnetic separation, paper-bed filtration, oil/water separation, post-filtration, heat exchange, and cooling operate as an integrated process at the flow rate required by the mill. Recovered oil contains 2% water or less.

CapacityEngineered around the mill's required flow; systems have processed up to 990 GPM and can scale to 1,600 GPM or more
Recovered oil≤ 2% water; potential reclamation or reuse depends on composition, waste classification, and recipient requirements
Typical plantsTube and pipe mills and steel mills, with heavy chip and tube-oil load

System selection

C.R.O.S.S. provides facility-level coolant recovery, while T.O.S.S. treats coolant at an individual reservoir. Operating scope, coolant volume, contaminant load, and facility layout determine the appropriate equipment.

Configuration questions

Planning central coolant recycling

  • 01

    Does clean-coolant distribution have to serve the whole shop?

    No. Clean-coolant piping can serve selected cells while portable equipment supports machines outside the distribution area. This creates a hybrid configuration.

    Hybrid configuration →
  • 02

    Can EdjeTech evaluate my coolant and contaminant load?

    Yes. EdjeTech reviews coolant compatibility, chip load, operating conditions, and required throughput before recommending a system configuration.

    Talk to an engineer →
  • 03

    What information is needed for a quotation?

    Provide the machine count, coolant type, approximate flow or weekly coolant volume, contaminant load, and preferred transfer method. The savings calculator can provide an initial operating-cost estimate.
