Air Force High Temperature & IR Combination Dryers

Air Force High Temperature & 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.

The Natgraph modular range of Air Force Dryers is available in 8 belt widths from 90cm through to 215cm and is also optionally available with high temperature air (up to 200°C). A combination of either Infra Red lamps within the hot air and Ultra Violet lamps within the cold air module, as well as refrigerated air systems, make these dryers extremely adaptable. These versions of Natgraph’s world famous Air Force Dryers have all the same features and build quality as a standard unit, but with the added versatility of High Temperature Forced Air, Infra Red and / or UV curing in the same dryer.

The construction of these High Temperature Dryers is completely different from a standard unit, with extra insulation layers and air gaps required to keep the external surfaces cool, even though it can be over 200°C inside the dryer. The air recirculation system uses a different principle, as the hot air needs to be retained in a specially insulated, inner ducting system that has an additional insulation layer.

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 Filters: 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.
Variable Output of Infra Red Lamps: An optional system can be fitted to control the output (power level), of the Infra Red lamps on a percentage basis, this system can be very useful when the effects of the IR can be critical, or are unknown. This system is controlled by the Touch Screen PLC Control System with a digital output.
