HZAD-P series dry air generator is designed to provide high-purity dry air with a dew point of - 55 ℃~- 70 ℃ for the installation and maintenance of large power equipment such as transformers and reactors. It can replace the traditional drying methods such as hot oil circulation, nitrogen supplement, vacuum extraction, and is more efficient, economic, safe, and environmentally friendly.
When HZAD-P series dry air generator is used for installation and maintenance of electric equipment, it can not be affected by the change of external climate conditions, especially overnight operation. It is only necessary to seal all flanges and fill the dry air to 0.02~0.03Mpa. There is no need to inject oil, supplement nitrogen, vacuum, etc. The transformer, reactor and other electric equipment will not be affected by moisture, which greatly reduces the workload and shorten the construction period Improve the effect of installation and maintenance quality. The HZAD-P series dry air generator is also applicable to air drying and circulation drying in warehouse, packaging, electronics, medicine and other industries, and also applicable to nitrogen, generator unit hydrogen and SF6 equipment drying.
It replaces the traditional drying method, which is efficient, economical, safe and environmentally friendly. It integrates air compression, cold drying and adsorption, and can move freely.
