Air Force Dryers

02.04.2012

Natgraph manufacture a range of Air Force Dryers that has been developed from many years of experience gained in the design and production of over 700 Forced Air Conveyorised Systems, that are in use world-wide.

These units have been designed, developed and manufactured for drying surface coatings applied to graphics, glass, medical products, textiles, automotive, electronics and aerospace etc, so no matter what the application, Natgraph have a solution.

With 7 standard belt widths, Touch Screen PLC Control System, 4 layouts and modular design, this range of dryers is extremely adaptable and offers the versatility and efficiency that is required in today’s production environments.

Features

  • Touch Screen, PLC Control System
  • Motor/vee belt, fan assemblies
  • Fully insulated
  • Easy access hoods
  • Extraction control
  • Vacuum hold-down
  • Modular construction
  • P.T.F.E. fibre glass belt
  • Castors & jacking feet
  • Colour coded to industry standards

Options

A variety of options are available for the range of Natgraph Air Force Dryers, these are intended to make the dryer more productive and versatile, whilst ensuring they fit into the intended location as efficiently and economically as possible.

Extended inlets and outlets

The inlet and the outlet of these dryers can be extended to enable the dryer to operate with more than one printing machine, or allow extra time for ‘ink flow’. These extensions are in multiples of 0.5m or 1m sections and can be fitted with vacuum hold-down systems.

Power Supply Socket Outlets

Electrical power supply socket outlets can be fitted at each end of the dryers, these are intended to provide an electrical supply for the printing machine and Stacker or Vibrating Collection Tray. This facility means that only one cable needs to be provided to supply the complete printing line, thus saving on installation costs.

CCTV Stack Monitoring System

A colour CCTV system can be fitted to all Natgraph dryers. This system includes a freestanding, mast mounted, camera above the stacker and a dedicated TV monitor mounted on a fully adjustable stand above the inlet of the dryer, which allows the operator to see the stacker without leaving the printing machine; a very important consideration when operating long, high speed, fully automatic printing lines.

Layout & Paint Finish

Air Force Dryers can be manufactured in any layout to suit the intended location or printing machine. The controls and ducting can be s house colours.
Natgraph Air Force Dryers are mostly manufactured in single, double or triple module combinations, these are from 3.5m upwards in length and the final specification is dependent upon the production speeds required and the drying rate of the ink. The best way to determine the ideal specification is to carry out drying trials in Natgraph’s Nottingham based ‘Drying Solution Centre’, which is available to all.

 

Freestanding UV and Compact UV Dryers

02.04.2012

Natgraph manufacture a range of Freestanding Ultra Violet (UV) Dryers that has been developed from many years of experience gained in the production of over 500 conveyorised UV Dryers, in daily use world-wide. Natgraph UV dryers are widely acknowledged as the coolest and most efficient available.

These dryers have been designed for curing UV surface coatings applied to promotional, electronic, credit card, glass, display and telecommunications products, as well as 3D objects etc. If there is a UV curable ink available for an application, Natgraph will have a solution.

With 8 standard belt widths, Touch Screen PLC Systems, 4 layouts, optional pre IR, Ozone Filters and Intelligent UV Control Systems, this range of dryers is extremely adaptable, versatile and efficient.

Natgraph also manufacture a range of Compact UV Dryers for applications where space is restricted and less temperature sensitive substrates are to be processed. This range utilises the Natgraph 1m UV Module to provide a high specification UV system in the minimum of floor space.

Options

Drop Down Inlet

A drop down inlet module has been developed by Natgraph for use when a dryer is in production with a cylinder press. This consists of a stainless steel table fitted with a vacuum system and transport belts. The table can be lowered to allow the operator easy access to the screen frame for cleaning etc. The table is moved by pneumatic cylinders, operated by one of 2 safety key switches (one located on either side of the dryer). This module is available for all sizes of Natgraph Air Force Dryers and adds 500mm to the length
of the dryer. These modules require a compressed air supply.

Ozone Filters

Natgraph have designed ozone filter assemblies to operate with their range of UV Dryers. Ozone gas is produced by UV lamps and must be extracted from the dryer efficiently. The ozone is normally extracted from the dryer through ducting to the outside of the building. All of Natgraph's UV Dryers have an efficient and fully sealed extraction system to ensure that all the ozone produced is removed.

If there is no easy route to the outside of the factory, or there are environmental reasons that gases or noise should not be emitted from the factory, the ozone must be removed by a filter system. Natgraph's Ozone Filter does this and also allows the heat generated by the UV dryer to be re-used within the factory, thus saving on heating costs.

There is a replaceable pre-filter that removes any airborne particles within the unit. If this filter is regularly replaced, then the charcoal filters within the unit will never need to be changed. These units are designed to function without reducing the efficiency of the UV dryer.
