Efficient, Hygienic, High Performance Humidifying System

Luwa’s TexFog is a high pressure humidification plant for special treatments in non-woven and textiles industries. The intended purpose of this system is to control exactly the humidity level of your air flow, using partial saturation via pumps, controlled by frequency inverters.

High efficiency factors and a generally low consumption are reached by a fine atomization of water. Even the energy consumption of all used pumps is reduced to a minimum. The use of fresh tap water and the instant disposal of wastewater ensure a high level of hygiene inside the TexFog.

Applications

• Nonwovens
• Food industry
• Manufacturing of hygiene products
• Textile industry (ex. weaving, twisting, etc.)

Benefits

• No water tank necessary
• Lower power consumption
• Hygienically safe (VDI 6022)
• Small amounts of spray water
• Maintenance and service-friendly
• Complete stainless-steel enclosure
• Minimum pump tower requirement
• High degrees of humidification and evaporation

The impeller with its characteristic sickle shaped blades is designed for optimal aerodynamic performance and most efficient operation. The use of high-end materials and modern production methods allow for the unique shape of the blades – a factor contributing significantly to the excellent performance of the axial flow fan. A special nano-coating prevents dust deposits during operation to keep efficiency constant at maximum level at all time.

Advantages:

• Higher efficiency – lower power consumption
• Aerodynamic aluminium blades
• Corrosion free design
• Higher fan capacity
• Wide range of configurations for best fitting operation point
• Sturdy industrial design
• Nano-coating for increased efficiency
• Reduced noise level
• Adjustable blade pitch angles

Luwa centrifugal fans are suitable for all industrial applications. Compared to Luwa’s Axial Flow Fan, the Radial Flow Fan offers higher conveying pressure ratios at a slightly lower sound pressure level.

The different versions available are selected according to your application and requirements and integrated into the overall system supplied by Luwa.

Advantages:

• Energy efficiency
• Wide volume flow range
• Possibility of customizing the fans according to your requirements

Applications:

• Suitable as supply air, exhaust air or process air fan in industrial applications
• For increased demands on the sound pressure level

REGULATE

In textile manufacturing processes, many factors influence the productivity and quality of the yarn. The main task of air conditioning and filtration systems is to keep these factors under control to achieve the highest profit from the installed production capacity.

• Constant relative humidity, within a range of ± 2.5 % RH at all times
• Even temperature profile to keep fiber fly under control
• Elimination of influence from outside air
• Air balance in all production areas
• Energy Use
• Any deviation from optimum performance parameters

CONTROL

Ideal regulation of the textile production space is achieved by a harmonized interaction of mechanical air moving equipment, digital control and precise sensors. DIGICONTROL 7 delivers this harmony, unlike random assemblies of hardware and software.

Switchboards

All Luwa switchboards are custom designed for the task. We adhere to European, US and other local standards to produce the safest and most rugged control panel and switchboard design.

MONITOR

The right information delivered to the right people in the right way is the capstone of DIGICONTROL 7 performance.

Most Nonwoven Process machines have integrated suction points that can be incorporated into a fibre deposit system. The fibre separation and dust filtration plant must be designed in such a way that it can handle the required air volume and also the amount of waste fibre.

Depending on the raw fibres used in the plant, several fibre separators can be installed to separate the different materials from each other.

The dependency on the fibre depositing system is essential for the operation of the process. A standstill of either the fibre depositing plant leads to an immediate shutdown of the entire process machine.

The MultiCell filter is built up as a filter wall in air conditioning stations for the filtration of return air, which is contaminated with dust and fibers. The special design with bottom entry filter cells prevents clogging of the filter with fibrous material:

• Smaller service bay
• Shorter A/C stations
• Fast and easy change of filter medium
• Increased filter surface for energy saving
• Only 1/3 of the space required compared to rotary filters
• Simple and sturdy 2-axis movement drive of suction nozzle

The rotary air filter is a well proven fine dust filter for exhaust air with a high concentration of dust and fibres in spinning and weaving mills. The high efficiency of this filter guarantees that the MAC prescriptions for exhaust air are adhered to. It is an economic solution for applications where enough space is available.

Characteristics:

• Automatic cleaning of the filter drum with a suction device fitted on the side
• Controlling of the cleaning process by differential pressure guards
• One filter mat per drum segment shortens the maintenance time
• Thanks to the suction device fitted externally, maintenance is also possible during operation
• Application with pre-fabricated housing or in a walled room

Advantages:

• Excellent cleaning effect
• Short installation time
• Easy maintenance

The efficient ceiling cleaning fan for industrial buildings.

Due to its cyclic blowing regime, the Luwa Circulaire prevents permanent dust deposits on pipes, cable trunks and construction frames of the building, hard to reach in industrial halls.

Labour-intensive, dangerous and costly cleanings, which must be carried out under increased safety requirements on ceilings or overhead beams, are no longer necessary.

Advantages:

• Eliminates manual overhead cleaning, especially where access is difficult
• No accumulation and dropping of dust deposits in the production area
• Saves costs and improves working conditions
• Reduces fire hazard (lower insurance premium)
• Easy and quick assembling

Applications:

• Commercial laundries and textile service
• Spinning and weaving plants with exposed ceiling construction
• Nonwoven and technical textiles
• Paper converting
• Warehouses, especially with crane runway

Function

Cyclically blowing keeps ceiling and machine structures dust-free. Due to the oscillatory rotational motion of the Circulaire® with a horizontal rotation of 360° and an 80° vertical oscillation, a cleaning area with a radius up to 32 ft will be achieved. Depending on the dust, the Circulaire® can operate continuously or by the hour.
