Inlet Vane Controls

Inlet vane controls are used for efficient volume flow regulation directly in the intake area of fans. This technology enables precise adaptation to fluctuating load requirements without the energy losses typical of simple throttling systems. By specifically influencing the inflow, the efficiency of the fan in partial load operation is significantly improved, leading to a noticeable reduction in operating costs.

Function: High-efficiency volume flow control
Advantage: Efficiency optimization in partial load operation
Special features: Robust mechanical adjustment, high control accuracy

Industrial Silencers

Industrial noise protection concepts are based on splitter or tubular silencers that combine maximum acoustic performance with minimal aerodynamic resistance. The individual design ensures that statutory noise protection limits are met without compromising fan performance through unnecessary pressure losses. The designs are tuned to the specific frequency spectra and flow velocities of the respective process.

Types: Splitter, tubular, and absorption silencers
Performance: High insertion loss with low pressure drop
Special features: Individual acoustic design, corrosion-resistant materials

Industrial Insulation

High-quality thermal and acoustic insulation minimizes heat radiation, thereby increasing the energy efficiency of the entire plant. At the same time, it serves as effective protection against contact to increase occupational safety. By reducing thermal stresses, the service life of housings and attachments is extended, while acoustic insulation contributes to lowering the noise level in the plant environment.

Purpose: Heat protection, cold protection, and sound insulation
Application area: Housings, ducts, and piping
Special features: Resistant to extreme temperatures, durable materials

Industrial Filter Units

To protect mechanical components from abrasiveness, contamination, or harmful particles, specialized filter units are integrated into the airflow. These systems prevent premature wear on impellers and housings, which significantly increases the plant’s service life. Constantly high process air quality is ensured by the reliable separation of solids.

Types: Sand filters, pre-filters, pocket filter units
Benefit: Significant reduction in wear damage
Special features: Maintenance-friendly exchange systems, individual filter classes

Industrial Expansion Joints

Flexible connections made of fabric or metal compensate for thermal expansion, mechanical vibrations, and installation inaccuracies within the ducting system. By decoupling the plant components, stress cracks and damage to the pipelines are reliably prevented. The design is gas-tight and optimized for the specific pressure and temperature loads of the medium.

Variants: Fabric and metal expansion joints
Task: Absorption of multi-axial movements and vibrations
Special features: High chemical resistance, pressure-resistant construction

Industrial Ducting Systems

Flow-optimized piping and ducting systems form the logistical network for process air. Manufacturing in round or rectangular design adheres to strict requirements for gas tightness and pressure resistance. Precise construction avoids unnecessary turbulence, which lowers the overall resistance of the system and supports the efficiency of the fan used.

Geometries: Round and rectangular ducts
Materials: Steel, stainless steel, special alloys
Special features: Pressure-resistant and gas-tight design, precision fit through 3D design

Industrial Chimneys

Industrial chimneys are individually developed considering complex static loads such as wind loads or seismic activities. They ensure the safe discharge of hot or aggressive process gases into the atmosphere. The choice of material is based on the chemical composition of the exhaust gases to ensure long-term corrosion resistance and stability.

Statics: Designed according to current standards for wind and earthquake loads
Construction: Individual heights and diameters
Special features: Integrated measuring ports, climbing systems, high corrosion resistance

Industrial acoustic enclosures

Modular enclosures that completely encapsulate noise sources ensure maximum reduction of sound emissions. These acoustic enclosures allow for the operation of noise-intensive units in close proximity to workplaces or residential areas. The construction includes integrated access for maintenance purposes without compromising the acoustic protection function.

Damping: High noise level reduction through optimized wall structures
Construction: Modular panel design
Special features: Including inspection hatches, ventilation systems, and soundproof doors

Repair, Service & Maintenance

A manufacturer-independent service concept ensures the permanent availability of air technology systems. The scope of services includes preventive measures such as vibration measurements and bearing analyses, as well as the complete repair and energy-efficient refurbishment of existing systems. Through regional presence and specialized expertise, downtimes can be minimized and the life cycle costs of the machinery reduced.

Scope: Inspection, repair, performance enhancement (retrofit)
Analysis: Vibration and noise measurement, characteristic curve determination
Special features: Service for third-party brands, 24/7 support availability, spare parts supply in original quality
