Product Description

China Vapor Phase Drying Oven (VPD plant)

Vapor Phase Drying (VPD) Plant from China / Chinese Vapor Phase Drying Plant

Vapor Phase Drying technology is from Europe, invented in 1960s. China brought in this technology in 1980s. Kerosene vapor is used as heat-transfer-medium to dry transformer (mainly above 110Kv, power transformer).
Advantages of VPD plant:
1. Drying under no oxygen condition, final heating up temperature can reach 125~130c.
2. Heating speed is fast; Heat of kerosene phase changing is 306.06kJ/kg. As it is vapor heating, every part is heated evenly.
3. Water is extracted from insulation material very fast. After drying, moisture content is very low.
4. Kerosene can wash dust and foreign material on transformer.
Parameters of our VPD plant:
Ultimate vacuum
0.1 mbar
Leakage rate (unload, cold condition)
< 5 mbar*L/ s.
Temperature of autoclave wall during fine vacuum phase
125~135 ° C
Temperature accuracy controlled
± 3° C
Temperature of insulation material
110~125° C
Average temperature of the dried object
120° C
Now, Vapor Phase Drying Plant is the most popular drying method for power transformer production. Even it is a requirement of transformer user.
We supplied VPD for Siemens, ABB, TBEA group etc.
And exported VPD to South Africa, Vietnam, and Pakistan etc.
Our VPD experts were involved in VPD researching field more than 30 years. Supplied more 30 sets VPD plant for transformer manufacturers.
Now, we have most advanced movable VPD for site drying of transformers at power substations.
