AIR FORCE DRYERS

Features:

  • Stencil Processing

  • Screen Printing

  • Air Force

  • Infrared 




Hansa Enterprises manufacture a range of air force dryers, which has been developed from the experience gained from the design and manufacture of many Forced Air Conveyorised Systems that are in use. These units have been designed, developed and manufactured for drying surface coating applied to graphics, glass, medical products, textiles, automatics, electronics, aerospace, etc.

These dryers have modular design and are extremely adaptability and offer the versatility and efficiency that is required in today’s production environments.

These dryers have refrigerated cooling modules with external hot gas bypass system connected to an commercial air conditioning plant.


These dryers have split belt section between the drying and cooling systems, with stainless steel vacuum bed and fiberglass with Teflon coated conveyor belts.

These dryers have a balanced vacuum system throughout the stainless steel bed with pneumatic lifting hoods for easy access. They have pneumatically operated drop down inlet for cleaning the printing machine by the operator.

These modular range of air force dryers are available in four belt width sizes. Therefore an air force drying system can be specified for all drying requirements. These can be from small print runs on hand printing tables, to medium length production runs, printed on semi automatic screen printing machines to continuous high speed production on fully automatic cylinder press.

Another important application for these air force dryers are for drying multicolor stickers and also for scratchable silver inks. 

          
         The above photo show an air force dryer of 8300 mm length and conveyor belt of 1066 mm width.


Keeping in mind the likely move towards water-based inks and and so also the constant presence of ozone (a corrosive oxidant within the UV modules), all Hansa dryers have been produced from stainless steel, to eliminate corrosion on the insides and the bed of the dryer.

The dryer range is truly modular, with each individual module having its own price and capable of functioning on its own. The size and make up of the dryer can be as per the customers’ individual requirements. Indeed, should a customer wish to re-arrange or upgrade a dryer which is already installed,, the same can be done without any difficulty. 

 
UV/IR Modular Systems

Using Reflectors with very small dimensions, we can install UV / IR units in every kind of printing machines, whether roll or sheet-fed offset. Such installation could be positioned either just before the pile delivery or after each printing unit. On request, the unit can be also be equipped with a shutter device to prevent overheating risks and to reduce risk of a fire hazard. This modular system allows a high versatility and flexibility and is capable of meeting all the requirements of the user. Each unit is independent and includes its own supply, controls, and cooling system.
 

           

 
• UV Lifting Section

UV curing hoods are fitted with a gas assisted lifting cylinder. This enables easy lifting of the hoods for cleaning the lamps and reflectors, and also for checking the  condition of the lamps and reflectors.

• Front Panel

All the lamps are independently controlled with each having a separate transformer. So, only the lamp/s that you need can be switched ON, still retaining the other lamps in OFF state. Each lamp is also provided with an hour meter that lets you monitor the number of hours the lamp has been ON. Besides, a digital speed indicator is provided in order to give an accurate feedback about the belt speed . UV / IR / Hot Air curing equipment will have separate controls for UV section, IR section & Hot Air section.

• Lamp Cassette

The UV lamps and reflectors are mounted in a separate box. Removal and replacement of the lamps and reflectors are very easy. Further, once the hood is lifted the electrical circuit gets cut-off automatically for operator safety.

• Exhaust Regulator

Each module is fitted with its own exhaust regulation control. This enables precise regulation of the exhaust air flow from each module for vacuuming the bed and also for ozone extraction.

• UV Lamps & Reflectors

The UV lamps used in the equipment is from a world famous manufacturers in Germany/USA. The reflectors too, are imported from Germany. These reflectors have a unique feature in that, the secondary reflectors send UV energy away from the lamps, reducing heat build-up near the lamps, thereby, extending its life. Further, the secondary reflectors can be easily replaced.
