Best equipment for electrical industry
The reliable and economical generation and distribution of energy ensures the quality of life and economic growth worldwide. This requires systems that are available around the clock and must work efficiently.
As a company with many years of experience we are pleased to offer you turnkey solutions for all your needs regarding vacuum equipment for electrical industry.
Our solutions
Vapour Phase Equipment
Increasing quality requirements demand a more and more careful treatment under vacuum. After the initially applied technologies such as the hot-air circulation process, the vapour-phase drying process nowadays is the most efficient method to treat power transformers.
Preferred basis for this especially is the correlation between vapour pressure, temperature and residual water content in the paper. This most advanced method of the vacuum drying technology optimizes heat transfer, insulation stress and process time.
Advantages of vapour phase equipment
• The most energy-efficient equipment in the world
• Fully automatic system
• Outside-arranged evaporator
Vacuum Hot Air drying equipment
Our vacuum hot-air drying equipment provides excellent drying results. Benefit from a considerably reduced drying time!
In a comparison of our vacuum hot air equipment and conventional drying systems that are only operated at atmospheric pressure without vacuum, one characteristic clearly stands out: The drying time is reduced by nearly 50%.
Advantages of vacuum hot air-drying equipment
• Control of circulating air to be exchanged by a moisture sensor
• Optimized and uniform heat distribution through fans and air baffles
• All-around heating of autoclave by means of heat transferring oil, including door
• Online registration of dew point and water rate during the fine vacuum phase
LF drying equipment
Low-frequency drying equipment are fitting well for the fully automatic production of transformers. Simultaneous heat and vacuum drying ensure short process times.
Parallel heat treatment and vacuum drying allow to achieve short process times and an efficient use of energy. Low vacuum degrees throughout the whole process ensure optimum drying quality and minimum loss due to depolymerisation of the insulation.
Advantages of low-frequency drying systems
• Minimum depolymerisation and aging of the insulation
• Very short drying and oil filling times are possible
• Online temperature determination during low-frequency electric heating
• Complete drying and oil impregnation process under vacuum
Vacuum filling stations/Oil purification equipment
Features of vacuum oil filling machine for transformers
• Filling with purificated oil under vacuum
• Automated control including conveying line and inspection line is possible.
• Design and manufacture, according to the operating condition of customers.
• Stand alone oil purification equipment (500-20.000l/h capacity)
Stand alone vacuum pumping units
