The VARIO eco filters fine, free-flowing dust from various applications and achieves a very high degree of separation with low energy consumption.

best filter performance with minimum energy consumption
The VARIO eco is optimized in terms of energy consumption. Result: Low filter resistance, use of efficient fans and reduced compressed air consumption for filter cleaning. The high degree of separation enables clean air to be returned to the working area

The Venturi wet separator series is predestined for the separation of all those dusts that are difficult or impossible to separate with a dry separator. This type of extraction technology is particularly suitable for sticky dusts and moist gases.

Wet separators work according to the Venturi principle and are used in almost all industrial sectors and applications, including polishing and grinding. Venturi wet separators are extraction systems, also known as wet scrubbers or gas scrubbers

, and the extraction technology works like this: a gas stream is brought into contact with a liquid stream in order to absorb components of the gas stream in the liquid. The transferred components of the gas stream can be solid, liquid or gaseous substances. Pure liquid, i.e. water, is used as the scrubbing liquid.

Keller wet scrubbers provide clean air for grinding, blasting and polishing as well as in foundries and in the chemical and plastics industries, among others.

wet scrubbers can be the better option
Venturi wet scrubbers are used when other extraction systems, such as dry scrubbers, are not successful or only with difficulty.

Although the degree of separation is often higher with dry separators, wet separation is the safer and more reliable option for combustible, moist or sticky dusts, such as those produced during polishing or blasting.

The extraction systems are available in 5 device types with different disposal systemsFurther

The increase in highly productive manufacturing processes is leading to a considerable increase in the raw gas load caused by aerosols (mist, fumes and particles). This development calls for new solutions for machine extraction systems. The high-performance ^AERO® and ENA aerosol separators have been developed and designed to meet the highest requirements and ensure reliable extraction of emulsion and oil mist

The eLine electrostatic precipitator is a specialist for sticky aerosols, such as those produced during die casting.

Maximum 24/7 availability thanks to integrated cleaning technologyThe

automated flushing system largely relieves the operator of tedious cleaning work and enables virtually uninterrupted 24/7 availability.

A modular concept with 3 sizesThe

eLine electrostatic precipitator is designed as a flexible and scalable high-performance module. Modularization enables central separator systems with common functions. For uninterrupted 24/7 operation, an additional module can be used to bridge the cleaning cycle.

Maintenance ensures system

availabilityRegular maintenance and servicing of extraction systems ensures high system availability and therefore a smooth production process. In addition, the service life of the filters and the entire extraction system is extended.

Regular inspection by experts
After commissioning, ventilation systems must be checked for proper functioning at regular intervals, but at least once a year, in accordance with DGUV 109-002 and the German Ordinance on Industrial Safety and Health and the Ordinance on Hazardous Substances. These inspections must be carried out and documented by persons qualified to do so. The specialists at Keller Service meet these testing requirements and will be happy to assist you with the inspection and maintenance of your extraction systems.

Maintenance and service for third-party systems
Whether purchased from Keller or not, Keller ensures that all your extraction systems are optimally maintained. We already have a large number of extraction systems from various manufacturers in our regular maintenance scope. As a result, we are constantly expanding our experience and the know-how of our service technicians.

We are your reliable and competent partner for maintenance services and repairs!

Supply air and heat recovery systems use the thermal energy from the process exhaust air to heat the outside air supplied.

Why supply air is so important for extraction systems!

In order for a process exhaust air extraction system to work effectively, a sufficient supply of fresh air must always be guaranteed. This ensures that there is no negative pressure in the process area that could disrupt extraction and endanger the working environment.

The advantages of a well-planned supply air system are:

Optimum extraction performance: The air flow remains stable thanks to the even supply of fresh air, the extraction system works optimally and the pollutants are extracted effectively.

Energy efficiency: The use of preheated supply air, e.g. via heat recovery systems, means that less energy is required for room heating.

Comfort: A regulated supply air supply minimizes draughts by introducing fresh air into the room evenly and at moderate flow rates. This increases the well-being of employees and contributes to a pleasant working environment.

Healthy working conditions: Regulated supply air ensures consistently high indoor air quality and benefits employees. The right balance between supply and extract air is crucial for maximum efficiency and safety in the production environment.

Using thermal energy to heat up supplied outside air and save heating costsIn

industrial processes, the extraction of process exhaust air is essential to remove harmful gases, dusts and vapours safely and efficiently. However, an often neglected aspect of these systems is the optimum supply air supply and the recovery of the heat contained in the exhaust air. Significant increases in efficiency can be achieved here. The integration of intelligent supply air controls and modern heat recovery systems can not only significantly reduce energy consumption, but also ensure more sustainable operation.
Keller-Lufttechnik has many years of experience in the planning and implementation of supply air and heat recovery solutions for various industries. Find out more about the key technologies and their benefits.
