SELTEC SMP Series

One standard for
mixing and supplying coolant.

SMP mixes concentrate and water at the concentration you set, stores the mix and supplies it automatically to all your machine tools. The mixing and topping up your operators repeat every day is handled by the system.

  • 3,000L/hMax. supply capacity
  • 30Machines on one system
  • 30%Lower coolant costs (up to)

Even the best coolant suffers when the mix is wrong.

Water-miscible coolant only works when concentrate and water are mixed in the right ratio. When operators mix and top up each machine by hand, the result changes from person to person and from day to day.

  • Every operator mixes differently

    Measuring by eye means the same machine runs at a different concentration each day, and part quality and tool life suffer.

  • Topping up never ends

    Carrying concentrate, measuring, mixing and delivering it to each machine is a daily chore.

  • Handling concentrate is a hazard

    Operators come into direct contact with concentrate, and spills on the way turn into slip hazards.

  • More machines, more to manage

    Every new machine is another point to look after, and keeping one standard gets harder.

How concentrate and water become ready-to-use coolant

A simplified animation of what happens inside the SMP, focusing on the principle.

  1. 1

    Concentrate feed

    A metering pump delivers concentrate at the set ratio.

  2. 2

    Water feed

    A water pump sends the water needed for dilution to the same point.

  3. 3

    Proportional mixing

    Concentrate and water pass through the mixing section and blend into a uniform emulsion.

  4. 4

    Storage

    The mixed coolant is stored in a tank, and level sensors track how much is left.

  5. 5

    Concentration check and supply

    The coolant passes a concentration sensor into the supply pump and is piped to the machines that need it.

  6. 6

    Machine top-up

    Individual sumps on CNC lathes and machining centers, or a central coolant system, are topped up automatically.

From mixing and carrying by hand
to a system that mixes and supplies for you.

The actual number of machines a system can serve depends on machine layout, pipe length, consumption and how many machines top up at the same time.

SMP-I4.0

Not just hitting the right concentration.
Managing it.

SMP-I4.0 adds real-time measurement and communication to mixing and supply. It logs concentration, pH and temperature and sends the data to your plant network and MES, so when a quality issue comes up you can look back at the condition of the coolant at that time.

  1. MeasureConcentration, pH and temperature are measured in real time.
  2. CompareReadings are compared against your set limits.
  3. CorrectIf a value drifts, the concentrate and water ratio is adjusted automatically.
  4. SupplyOnly coolant within spec goes to the machines.
  5. AlarmAny deviation triggers an immediate alarm.
  6. RecordEvery value is stored for later traceability.

How much could your plant save each year?

Enter figures from your plant to estimate savings with SMP. The values below are examples, so replace them with your own.

How it is calculated: 30% lower coolant costs, 80% less daily mixing and top-up time per machine, 240 working days per year. This is a rough estimate that varies with site conditions.

Frequently asked questions

Can SMP be connected to machines we already have?

Yes. It can be piped to CNC lathes and machining centers with their own sumps as well as to central coolant systems. We propose a configuration after looking at your machine layout and pipe runs.

Which coolants can it handle?

SMP works with water-miscible cutting and grinding fluid concentrates. Tell us the product you use and we will confirm it is suitable.

How do I choose a model?

By the number of machines, daily consumption and floor space. We recommend the SMP-LIGHT for smaller shops with up to 20 machines, the SMP-NEXT or SMP-PLUS for up to 30, and the SMP-I4.0 if you need concentration data logging and MES integration.

How much floor space does it need?

The smallest model, the SMP-LIGHT, is 400 mm wide and 800 mm deep. See the specification table for each model.

How is the concentration set?

Set the target on the control panel and the unit mixes concentrate and water to that ratio. The SMP-I4.0 also measures concentration in real time and corrects it automatically when it drifts.

What power supply does it need?

All models run on single-phase 220 V.

How are inspection and service handled?

SELTEC handles inspection, consumables and repairs. Choose Service request on the contact form and our team will get back to you. For sites outside Korea, support arrangements are agreed when the project is planned.

Do you supply SMP systems outside Korea?

Yes. SMP systems are already running at plants outside Korea. Send us your location and requirements, and we will discuss delivery, installation and support for your region.

Tell us about your shop and we will propose the right setup.

Share the number of machines to connect, where the unit would go and how you mix coolant today. One of our engineers will review it and get back to you.
