Pre-separator systems

Spark extinguishing system to prevent filter fires

With certain dusts from cellulose and metal processing, there is a constant risk of filter fire. If the sensor of this high-performance separator detects sparks being sucked in, the air supply is immediately interrupted so that the spark does not reach the inside of the extraction system.

The spark extinguishing system consists of coordinated components: Spark detector, evaluation electronics, actual separator. The high-performance separator with its collection container can be installed at any point in the pneumatic transport channel. In the event of an alarm, the control system takes all measures to raise the alarm and switch off machines and fans in stages. The smallest sparks are detected and extinguished using highly sensitive infrared sensors.

The spark extinguishing system complies with VDS guideline 2106.

Components of the spark extinguishing systems

Highly sensitive wireless sensors
Alarm center
Automatic deletion
Pressure booster system (if necessary)

Technical data
Air flow rate: 1’500-4’000 m³/h
Power consumption: 400 V 50 Hz 0.05kw

Spark pre-separator

If larger quantities of materials need to be separated, you should use a pre-separator. This is placed near the workstation or the central unit.

Intended use

For processing certain materials
For material transportation
To avoid overloading the central unit
To reduce the dust load via the filter unit
For separating liquids
For separating sparks
For fire protection

To be observed when using

The types of dust to be separated
The correct installation to enable easy emptying
The relationship between liquids and gases

Cyclone pre-separator

The cyclone separator is characterized by low acquisition costs, low space requirements, high operational reliability and low maintenance requirements. It works largely independently of the operating pressure and operating temperature.

Areas of application for cyclone pre-separators

For all dry, coarse and free-flowing dusts with relatively large dust volumes.

Your added value

Low maintenance
Low acquisition costs
High operational reliability
Low maintenance effort
Separation between dust and valuable particles
Low flow resistance
High filter system efficiency
Protection against overloading and clogging of the main dust extractor

Options

Throttle valve
Transition duct round or rectangular
Dust bunker
Pressure plate to reduce the pressure loss
Rotary valve
