Short description of each product:
Pressure relief flap to reduce of the pressure in the working area when an oil mist deflagration
Pipeclean® prevents the transfer of CL (direct return to the machine)
Pipeclean- EX® prevents the transfer of CL (direct return to the machine) and transmitted light from explosions in the exhaust system (in connection with Shut-off damper® and possibly Thermo sensor)

transmitted light from explosions in the exhaust system
Fluidbagck® Automatic siphon for the repatriation of CL into the machine
Thermo sensor to control the Shut-off damper® if there is no fire extinguisher
Spänetor® suction element for retention of metal sludge, metal dust and chips < 2 cm
FASS-3® AIR Suction element to the retention of chips > 2 cm with air cleaning
FASS-3® FLUID Suction element to the retention of chips > 2 cm with coolant flush
Airstep® Ventilation system for the detection of "dead spots" in the working area
LUPO® in different versions to monitor/display and control of the air power
Fire extinguishing system with sensors for the detection of fires and subsequent deletion of the fire

4.2 Pipeclean-Special®

×

To be used for machines with MQL connected to central extraction systems. For more information see
4.0. Pipeclean® oder 4.1 Pipeclean-EX®!

12 Spanspüler®

×

The Spanspüler® differs from conventional flushing heads due to its two overlapping flushing slots that are located side by side. Thanks to the chamfered ends of the slots, the cooling lubricant used for flushing, exits in a fan-shaped manner. This results in a three-dimensional cleaning effect. The combined action of the two fan-shaped flashing pulses is highly effective. PDFDownload brochure (pdf)! Click the picture below for a simulation of the mode of operation of the Spanspüler®!

5.0 Fluidbagck® (Siphon solution)

×

Collecting tank for cooling lubricant with metal sludge in form of a glass cylinder. It is equipped with ultrasonic monitoring and empties automatically. PDFDownload brochure (pdf)!Click the picture below for a simulation of the mode of operation of the Fluidbagck®!

10 Airstep®

×

When the ventilation technology is put directly into the working area, one or more air supply nozzles can be placed in optimum positions. The resulting air short circuit between the extraction point and the air nozzles transports the cooling lubricant mist (or dust) towards the extraction point. Air is only drawn in behind! In addition, cooling lubricant mist (dust) from behind the nozzle is removed due to the injector effect.PDFDownload brochure (pdf)! Click the picture below for a simulation of the mode of operation of the Airstep®!

02 FASS-3®-FLUID or -AIR
Flexible extraction location with 3 interfaces

×

The standardized extraction interface prevents carry-over of chips. Thanks to automatic cleaning, the entire extraction surface is available at all times (safety relevant for cooling lubricant oil!).PDFDownload brochure (pdf)!

03 Spänetor®

×

With Spänetor®, chips are no longer extracted! Thanks to the technology of the Spänetor®, the chips are returned to the machine immediately. When Spänetor® is used, 25% less air throughflow is required (= a significantly lower investment for the acquisition of extraction systems).

The effectiveness (= the required air exchange in the working area) is absolutely equivalent. In addition, the air velocity at the extraction point is ≤ 4m/sec. (presuming correct design).

06 Shut-off damper®

×

The shut-off damper® has the following tasks:

- to prevent that fire-extinguishing agent is extracted from the "ignited" machine by the still running central extraction system.

- to prevent that fire, which may not yet have been extinguished, is drawn into the central filter system.

09 Thermo sensor/Resiko®
Rerucha-Safety-Concept

×

For machine tools that operate with cooling lubricant oil or minimum quantity lubrication and without fire extinguishing systems. The machine is cleared via a central extraction system.
The components are:
- Thermo sensor
- Pipeclean-EX®
- Shut-off damper®

04 Pipeclean®

×

Mechanical pre-separator for oil, emulsion and water mist (without additives). No build-up of cooling lubricant! The condensed cooling lubricant (cooling lubricant reconditioning) is immediately returned to the machine. PDFDownload brochure (pdf)!

4.1 Pipeclean-EX®

×

Pipeclean-EX® prevents flashover of jet flames into central extraction pipes! When Pipeclean-EX® is used, the central extraction system can be operated without danger and all connected machines continue producing without interruption. With the already familiar "system guarantee" we assure the specified properties and functions!PDFDownload brochure (pdf)!

07 Fire extinguishing system

×

Fire extinguishing systems for a range of different requirements.

08 Wirbeltor®

×

When loading hatches are opened quickly for workpiece or tools change, the cooling lubricant mist escapes suddenly from the working area of the machine and contaminates the air of the production hall, in which people are working.

The air spins around and a cyclone is formed that prevents the cooling lubricant mist (oil or emulsion) from escaping. Therefore, fitting to the machine is simple. There are a couple of things that have to be taken into consideration.

The pressure release flap has the task to reduce the pressure wave in the event of deflagration and explosions in machine tools. PDFDownload brochure (pdf)!

EC-type-examination-certificate according to ATEX guidelines.
Test number BVS-05-ATEX-H-047-X

11 Lupo®

×

Lupo®is a new air positioning system and has been designed for the following applications: Exhaust air ducts with air flow velocities of 10-22 m/sec., cooling lubricant concentration < 400 mg/m3 , particles ≤ 400 µm, gas phase concentration < 1000mg/m3, static pressures < 50mbar PDFDownload brochure (pdf)!
