Oil Skimmers 2430E, 2450E and 2480E with Separator

The E series belt skimmer has a built-in oil separator that returns up to 90% of the skimmed emulsion to the tank and sends only waste oil to disposal. It mounts on a magnetic base and is easy to maintain. It ships ready to run with a power supply and a 600 mm band.

Emulsion returned: up to 90%
2430E: approx. 3 l/hour
2450E: approx. 5 l/hour
Magnetic base mounting

Oil Skimmers 2430i, 2450i and 2480i

In the i series the belt width sets the capacity: 30 mm on the 2430i, 50 mm on the 2450i and 80 mm on the 2480i. The insertion angle is adjustable and the unit disassembles quickly for mounting on a CNC machine. It is delivered ready to use with an 800 mm standard belt.

2430i: 3 l/hour, 30 mm belt
2450i: 5 l/hour, 50 mm belt
2480i: 8 l/hour, 80 mm belt
Standard belt: 800 mm

Funnel Skimmers 2430F-2480F and Disc Skimmer 24320D

For heavily leaking machines: the F series funnel carries oil, foam and plastic chips down to the belt, and an 80 mm belt is offered for extreme leaks. The 24320D disc skimmer with a 320 mm disc removes approx. 20 l/hour and suits machines with oil-lubricated bar feeders.

24320D disc: 320 mm
24320D: approx. 20 l/hour
F series: 80 mm belt option
Stick or magnet mounting

A900 Emulsion Mixer and Nimatic Mixer Range

The Nimatic mixer blends cutting fluid concentrate with water using water pressure only. The mix is continuously adjustable, a drop shaped dosing aperture holds very low doses and two ball check valves prevent faulty operation. Aluminium, brass or stainless bodies suit different additives.

Flow: up to 900/2,000 l/hour
Mixing ratio: 0 to approx. 16%
Cutting fluid savings: up to 30%
Aluminium body: pH 5-8.5

NC-200 and NRC-200 Pneumatic Machine Cleaners

The NC-200 machine cleaner is powered by compressed air and sits on a 50-218 litre barrel as a suction unit. A 1.5 m hose and nozzles are included, and the NRC-200 adds a reverse button and bottom tube. A float switch prevents overfilling and a pilot valve limits barrel pressure.

Working pressure: 2.5-10 bar
Barrel pressure: max. 0.25 bar
Barrel: 50-218 litres
Hose: 1.5 m

Nimatic Ozone Purifier for Coolant Tanks

The Purifier keeps coolant moving, brings micro-particles to the surface and reduces bacteria with ozone made without chemicals. It runs on 230V with programmable start and stop. The 80 mm and 125 mm models come with or without an ozone generator; the 80 mm unit works at liquid levels around 100 mm.

Ozone generator: max. 500 mg/h
Power: 230V, 12V DC adapter
Models: 80 mm and 125 mm
Hanging chain: 1 m

Brix Refractometers, Level Indicator and 240B Filter

The Nimatic refractometer reads coolant concentration from a few drops on the prism with +/- 0.2% accuracy and automatic temperature compensation, and a hidden calibration screw prevents accidental adjustment. Drums take the 308002 level indicator, and machine tanks the 240B compact bag filter.

Scales: 0-18% and 0-32% Brix
Accuracy: +/- 0.2%
240B filter: approx. 15 l/hour
Filter bag: 100 micron

Choosing a Skimmer for a Machine Tank

Nimatic belt skimmers remove hydraulic and spindle oil from the surface of metalworking fluids. Capacity depends on belt width: in the i series a 30 mm belt gives approx. 3 l/hour, 50 mm approx. 5 l/hour and 80 mm approx. 8 l/hour.

The E series with a built-in separator returns up to 90% of the skimmed emulsion and mounts on a magnetic base. For heavily leaking machines with foam and plastic chips there are the F series funnel skimmers and the 24320D disc skimmer with a 320 mm disc and approx. 20 l/hour.

Preparing Emulsion with the A900 Mixer

The A900 mixer runs on mains water pressure only: flow up to 900/2,000 l/hour and a mixing ratio continuously set from 0 to approx. 16%, with cutting fluid savings of up to 30% stated by the manufacturer. The body is chosen by the additive: aluminium for pH 5-8.5, or brass and stainless steel.

The lower threaded adapter fits standard drums, and two ball check valves prevent faulty operation.

Tank Cleaning and Coolant Care

The NC-200 pneumatic cleaner sits on a 50-218 litre barrel and runs on 2.5-10 bar compressed air; the NRC-200 also empties the barrel in reverse at a barrel pressure of max. 0.25 bar.

The ozone Purifier keeps coolant moving, brings micro-particles to the surface and generates up to 500 mg/h of ozone with no chemicals, in 80 mm and 125 mm models. The 240B compact filter with a 100 micron bag removes micro chips from the surface at approx. 15 l/hour.

Concentration and Level Control

The Nimatic Brix refractometer comes with 0-18% and 0-32% scales, +/- 0.2% accuracy and automatic temperature compensation, and a hidden calibration screw prevents accidental adjustment.

Too little concentrate means poor lubrication and a higher corrosion risk; too much raises heat and concentrate use. The 308002 level indicator shows the liquid level in the drum and fits all standard drums.
