VEIT machines are leading in technology and guarantee advantages in productivity, which means cost saving for you!

Roller Unit The rollers at the entrance closes-off of the Tunnel Finisher towards the entry. Thus it is guaranteed that both steam and hot air remain in the inner parts of the device and cannot escape.  Energy saving

Pre-treatment unit (1) The pre-treatment unit is operated by a steam-air mixture. Here, the steam comes from the vapor which is normally sucked out of the steam unit. Consequently, no energy is wasted and only a small part of the steam escapes to the environment.  Energy saving and improved finish results at the same time due to a longer application time of the steam. For large Tunnel Finisher two pre-treatment units are recommended in order to enhance the effect.

Pre-treatment unit (2) Steam Recycling System: A part of the steam which was formerly sucked out and blown away is now used in the pre-treatment unit to allow a better finish result for natural fibers as they need moisture.  Energy saving

Steam Unit (1) The steam unit(s) with their special and maintenance-free spray nozzles are the basis of the high quality finish result. The spray nozzles spray the steam – depending on the garments – either directly or indirectly onto the garments. Absolutely constant steam pressure on the nozzles independent from fluctuations of the boiler because of elaborate steam pressure control. Optionally the spray steam can be switched off to reduce the steam consumption in the lower part. Hence you can save energy with short garments.

Steam Unit (2) For long garments you also have the possibility to place nozzles on the ground which blow additional steam into the garments from the bottom unit. This further improves the finisher result for long garments. The steam units are equipped with a sensor technology which identifies garments that have fallen down and alerts the operator by a signal. Hence, these garments can quickly and easily be removed from the tunnel.

Steam / Air Separation Unit The separation module separates the steam unit, where the fiber is softened, from the air unit, in which the fiber is pressed and dried. The separation can be effected either by rollers or – especially suitable for voluminous garments – by an air curtain.

Direct-blow Air Unit (1) A characteristic of the VEIT Tunnel Finisher is the Direct-blow system in the air unit where the air stream is directly conveyed to the garments. Thus, high stretching forces are applied to the garments which contribute considerably to a good finishing result. A further advantage is the low power consumption of the Direct-blow system. 1,5 kW are sufficient for the maximum air output.

Direct-blow Air Unit (2) The air unit is constructed to be especially service-friendly. The fluff filters can be removed and mounted again for easy cleaning without any tools. The impellers can be pulled out for easy and quick cleaning.  high machine availability

Direct-blow Air Unit (3) Large heating registers allow quick heating which ensures that the temperature selected on the display is actually reached with short reaction times. Due to physical conditions a relatively high amount of heat is taken out of Tunnel Finisher. Therefore it is necessary to have large heating registers that are capable to compensate this loss to prevent the air temperate inside the tunnel from falling. Gauges and valves in every air unit allow a sensitive adaptation to the garments.

High-volume Finishing Unit The finishing unit adds the last polish to the garments. Through an air curtain at the exit of the tunnel warm air is blown into the garments from below. This causes the so-called „doll effect“, i.e. the garment is gaining volume with this technology. The garment looks as if it has been treated with a steam doll. As an option we offer an automatic height adjustment of the High-volume finishing unit. Here, the optimum height is automatically adjusted. Ideal for customers who often have different kinds of textiles passing the Tunnel chaotically.

Control The operation of the Tunnel Finisher is comfortable and easy due to the touch screen control. All parameters and the most important functions are available at a glance. The integrated management of the various finishing programs is also operated by the touch screen control. More than 200 programs can be entered, stored and retrieved again on request. Various interfaces are available on request, for example an interface to install printers, integrate the Tunnel Finisher into the company network or to control of the Tunnel via RFID or barcode.

Conveyor system The new VEIT hook system made of high performance reinforced plastic can handle nearly all kinds of hangers available on the market. The special support on the hook smoothly transports the garments safely through the Tunnel Finisher. The high performance material offers a very long lifetime and a trouble free operation. Two hangers can be loaded on one hook increasing capacity considerably

Advantages over competition Compared to the competition VEIT Tunnel Finishers offer various advantages: Summary: Heating registers Air channels Finisher unit Adjustable steam quality Control Conveyor system Separation module Steam exhaust at the entry Base/Compensator Fluff filters Steam extraction Energy Electric energy CE Conformity/Electricity Connection

Advantages over competition Heating registers: The competitors‘ heating registers are made of stainless steel.  stainless steel is only a moderate heat conductor with bad temperature absorption to the environment resulting in longer reaction times when quick reaction of the heating is necessary in order to keep a constant temperature. The competitors‘ heating registers are considerably smaller:  no reserves, air modules can be heated up to max. 120°C. Last air module at the exit fails to maintain the 120°C in practice! VEIT heating registers offer a considerably larger surface for the transfer of energy. VEIT heating registers are made from copper because of the excellent heat conducting qualities of copper.

Advantages over competition Air stream: Due to the arrangement of impellers, heating registers and air deflectors considerable losses in the air stream occur.  higher power consumption of the fan with decreased air output (4 kW from Indupress to 1,5 kW from VEIT)

Advantages over competition Finishing unit: No finishing unit, only a slide to avoid that too much air escapes. Despite of the slide high air exhaust, final air chamber cannot maintain the maximum temperature of 120°C. Bad finish result as the garments lack volume.  There is no „doll effect“! Slide only manually adjustable

Advantages over competition Steam quality / Dampness regulation: Competitors offer no possibility of influencing the steam quality. With VEIT it is possible to influence the steam quality via the Touch Screen Display. You can for example produce more wet steam to facilitate respectively to allow the finishing of natural fibers.

Advantages over competition Control: Simple operation, no integrated program management (loading via USB stick) No possibility to install different user levels. No possibility to enter user specific adaptations. Air temperature limited to max. 120°C.

Advantages over competition Conveyor system: Two hangers cannot be loaded on one hook. The design of the system is not very good. Ball Bearings are used to guide the hook. Because of the always changing conditions inside and outside of the tunnel, the conveyor system does not have a very long lifetime as the ball bearings cannot stand this stress for a long time. The width of the conveyor rail is huge so the air flow has to pass by this rail and the air flow is blown around big parts of the garment.

Advantages over competition Separation module: Steam is sucked off via a vacuum turbine between the steam module and the air module and is blown into the entry rollers.  Problematic: depending on the steam quality the rollers might become wet.

Advantages over competition Steam exhaust at the entry: Steam comes out clearly visible at the entry as there is no suction fan  Condensate problems! Stains on the garments resulting from dripping condensate.

Advantages over competition Bottom unit / rocker switch: The bottom unit inside the steam module is not well accessible:  considerable staining of garments which have fallen off accidentally. The rocker switch in the entire tunnel consists of curved steel wire.  fallen garments are not caught by the rocker switch but fall on the dirty floor.

Advantages over competition Fluff filters: The fluff filters cannot be removed without tools and can only be cleaned with a vacuum cleaner. For a more thorough cleaning the filters have to be detached with tools.  considerable time effort

Advantages over competition Steam extraction: Above the steam module there is an exhaust pipe with a 120mm HT pipe which sucks out the steam No fluff filter in front of the impeller! Extraction is not adjustable By integrating the pre-treatment unit(s) in front of the steam chamber VEIT offers the possibility to partially or even completely make use of the surplus steam. Thus, energy is saved and the finishing result is improved at the same time due to a longer swelling time of the garments.

Advantages over competition Energy: The competitors supply the steam spray register via reinforced hoses which have a diameter of 3/8“.  considerably less steam output possible than with VEIT. Natural fibers are more complicated to deal with for the competition as for VEIT due to less steam output. A lot of tubes are beyond the insulation and are only isolated by foam rubber.  higher energy losses than with VEIT: At VEIT almost all tubes are within the isolation.

Advantages over competition Energy consumption: e.g. Veit 8657 1+2 wide: 6,7 kW Indupress TFS-12: 11,5 kW, with slightly longer finish zone!

Advantages over competition CE Conformity / Electricity: The competitors have not implemented the valid CE conditions and violate the CE-mark regulation They do not fulfill the guidelines for the electro-magnetic compatibility (EMV)  in case that a violation of EMV guidelines is detected by the electricity supplier the customer might face a re-fitting of filters with costs of up to several thousand €. VEIT has already integrated the respective filters and fulfils all valid regulations.

Advantages over competition Connectors: Connectors are a potential source for malfunctions, especially under the conditions of the Tunnel Finishers (permeating moisture, corrosion of contacts, malfunctions) Moreover, connectors complicate the diagnosis of potentially occurring errors as they have to be disassembled before malfunctions can be detected. VEIT uses a bus based SPS. This makes wiring and error diagnosis very easy and time saving as every I/O can be checked from the display.
