Batch configuration

Batch recycling does not require central coolant piping

One C.R.O.S.S. can serve multiple machine sumps without a central piping installation. A portable transfer unit collects dirty coolant and delivers it to the system. Clean coolant is drawn from the system as needed.

Portable dirty-coolant collectionThe Green Machine or another compatible unit collects coolant along with swarf, chips, and sludge, then transfers the coolant to the system.
Clean-coolant distribution can be addedThe optional Coolant Return System pumps clean coolant through facility piping for distribution across the shop.
Recycling performance is retainedBoth transfer methods support up to 85% lower new-fluid purchases and up to 90% lower disposal costs.

Configuration fit

When batch recycling fits the facility

Batch recycling provides central coolant recovery without installing piping to every machine. Facility layout, machine count, and coolant volume determine the appropriate configuration.

Batch fits when
01Leased facilities or sites where floor modification is not practical
02Machine locations make facility-wide coolant piping impractical
03Portable transfer avoids the cost and disruption of facility-wide coolant piping
04Coolant recycling is needed before clean-coolant piping is scheduledThe optional CRS supports future clean-coolant distribution.

08Smaller operations where individual-reservoir equipment better matches the service requirementT.O.S.S. at the sump →
Operating consideration

Batch recycling uses scheduled portable coolant transfer. An operator moves the transfer unit between machine sumps and C.R.O.S.S. This avoids a facility piping project while combining coolant transfer with sump-cleaning work already required by the shop.

Batch recycling equipment

Portable transfer and central coolant recycling

A portable transfer unit collects dirty coolant from the machine sumps. C.R.O.S.S. separates contaminants, stores clean coolant, and prepares it for reuse.

Dirty-coolant collection

Portable coolant collection and transfer

Green Machine · air-powered portable sump cleaner

Vacuum collection removes coolant, chips, and sludge from the sump. Bag filtration captures solids during transfer, and the unit discharges directly to C.R.O.S.S. A typical sump cleaning that can require about four labor-hours can be completed by one person in approximately 15 minutes.

Coolant separation, storage, and concentration control

Coolant Recovery Oil Separation System · batch configuration

Dirty tank, oil/water separator, clean tank, and coolant proportioner on one self-contained skid. Dirty coolant enters through the dirty-tank inlet coupling. Potential reclamation or reuse of separated oil depends on its composition, waste classification, and recipient requirements.

Throughput120–1,500 GPH across six models, sized to weekly coolant volume
Separation99.75% of tramp oil and particulate removed, by volume
UtilitiesRequires the specified electrical service and city-water connection, with no central piping installation

Compatible transfer equipment

Compatible transfer equipment can also be used. The Green Machine is the recommended EdjeTech sump cleaner, but another compatible vacuum, transfer tote, or pumping unit can feed the C.R.O.S.S. dirty-tank inlet.

01

Vacuum the sump

The transfer unit collects coolant along with chips, sludge, and tramp oil. A typical sump cleaning takes approximately 15 minutes.

02

Transfer coolant to C.R.O.S.S.

The portable transfer unit moves to C.R.O.S.S. and discharges into the dirty tank through the inlet coupling.

03

C.R.O.S.S. removes contaminants

The system processes dirty coolant while maintaining clean coolant for immediate use 24/7/365.

04

Return clean coolant

Refill from the clean-coolant outlet. A Green Machine with the DTS configuration can return clean coolant on the same sump visit.

Each sump is serviced according to a planned schedule. The system recovers coolant for reuse, reducing new-fluid purchases and disposal volume.

Batch recycling performance

Recovery performance without central piping

Portable transfer changes how coolant moves through the facility, not how C.R.O.S.S. separates contaminants and prepares coolant for reuse.

Configuration questions

Planning a batch recycling system

  • 01

    Is the Green Machine required for batch recycling?

    No. Any compatible sump cleaner or pumping unit can feed the system. The Green Machine is the recommended EdjeTech unit because it filters coolant during intake, and the DTS configuration can refill the sump during the same service cycle.

    See the Green Machine →
  • 02

    Can clean-coolant distribution be added later?

    The Coolant Return System is available within the same model line for clean-coolant distribution. A hybrid configuration can serve the main production cells through piping while portable equipment serves remote machines. If future expansion is planned, EdjeTech can confirm whether the selected unit can accept the Coolant Return System later.

    Hybrid deployment →
  • 03

    How many machines can one batch setup cover?

    Machine count alone does not determine capacity. Total coolant volume, required processing rate, sump-service frequency, and the model line's 120 to 1,500 GPH range determine how many machines one system can support. For smaller operations, EdjeTech may recommend individual-reservoir equipment instead.
