GF Air drying Machine:
GF dry air generator：
GF dry air generator is widely used in electric power, metallurgy, electronics, food, chemical, petroleum, medicine, tobacco, instrumentation, automation control and other industries. In the power system for large transformer and reactor can show its unique superiority, he can ensure that the transformer in the repair process of internal insulation is not damp, not affected by the outside world climate change, especially the overnight job, only need to charge into the appropriate air drying equipment, to avoid the heat of traditional transformer oil the drying cycle mode, can ensure the high insulation material to improve moisture and reduce oil insulation, but also to ensure the safety of inspection personnel.
Technical features:
1. It adopts high-pressure twin-screw air compressor, low temperature condensation technique and cyclonic coalescence dehydration, A/B tank regeneration adsorption dehydration technology, high precision coalescence dehydration filter, 0.01 M precision filter to ensure the air cleanliness, simple operation, energy saving, safe and reliable.
2. It large capacity of drying machine to ensure that the air and the dryer has sufficient contact time, so that the machine can fully absorb moisture, to achieve a stable outlet dew point. The additional 30% of the dryer can make up the natural aging of the dryer and prolong the service life.
3. It is comprehensive utilization of cold dry machine, suction machine, ultra precision filtration and other scientific optimization of the ratio, resulting in high quality and low dew point of the dry air.
4. dryer adopts the unique design of the removable stainless steel tower gas diffuser, uniform distribution, avoid channeling phenomenon.
5. Integrated design, with full automatic PLC, touch screen control, self inspection of the operating parameters.
6. It has multi cycle micro heating device, high heating efficiency, low air consumption, maximum energy consumption.
7. It is advanced microcomputer touch screen control system, automatic timing, automatic switching, time setting, fault alarm function.
