Air Force High Temp / IR Combination Dryers

 Natgraph manufacture a range of Air Force High Temperature and IR Combination Dryers that has been developed from many years of experience gained in the design and production of over 150 IR High Temperature Conveyorised Systems, in daily use world-wide. These versatile dryers have the ability to dry specialist inks using either a combination of Infra Red radiation and hot air, hot air alone or even combined with UV.

These dryers have been designed, developed and manufactured for drying surface coatings applied to textiles, glass, telecommunications products, automotive and electronics etc. If there is a special ink available for the application, Natgraph will have a solution.

With 8 standard belt widths, Touch Screen PLC Control System, 4 layouts, IR lamp systems, hot air up to 200°C and modular design, this range of dryers is extremely adaptable, versatile and efficient.

A variety of options are available for the range of Air Force High Temperature and IR Combination 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.

Refrigerated Cooler Modules

An optional refrigerated cooler module can be specified where extra cooling is required, or the substrate exit temperature needs to be very low. This is also very useful if the printroom is likely to develop very high ambient temperatures. These modules recirculate the air through an internal cooling coil (with air filter) that is connected to an external water chiller plant by flexible pipework. Water is cooled by the chiller plant as required to maintain a controlled temperature within the module.The chiller plant requires a separate electrical power supply, but is controlled from the dryers' PLC system.

Recirculation Filters

An optional air recirculation filter system can be fitted to each high temperature module as an option. This unit has a replaceable, slide in filter, rated at 200°C with a filter rating of EU4 (4 microns). It is located within the top of the ‘hot box' inside a stainless steel enclosure which has been designed to maintain air efficiency within the dryer whilst preventing contamination.

Inlet Filter

An optional inlet air filter stack can be fitted to each dedicated air inlet to ensure that the air being drawn into the dryer is free of dirt and dust. This freestanding filter stack has a replaceable, slide in unit, with a filter rating of EU4 (4 microns) and has been designed to maintain air efficiency for the dryer, whilst preventing contamination.

Thyristor Drives

An optional thyristor drive can be fitted to control the output of the Infra Red lamps on a percentage basis, this system can be very useful when the effects of the IR on the substrate can be critical, or are unknown. The thyristor is controlled by the Touch Screen PLC Control System with a digital output.
