Industrial Furnaces


PVA TePla started business from vacuum equipment two decades ago, which means that we already have a lot of experience in the high-temperature and high-pressure atmosphere furnace. We can offer our customers with high temperature and high pressure furnaces. The market share of our furnaces is over 50% in the world. Our furnaces’ temperature can be as high as Celsius 3,000 degrees. We can create environment for specified gas which includes chlorine, argon, saline, nitrogen..etc.

What are we able do:

  • Temperature up to Celsius 3,000 degrees
  • Gas pressure up to 100 bar or vacuum
  • Variety of Specified gases
  • Fast Cooling design
  • Precise temperature control
  • Graphite heater or Molybdenum heater

The applications of our product in vary Industries:

  1. SiC mono crystal growing:
  2. Due to the characteristics of high temperature and chemical stability, SiC single crystal structure has gradually attracted attention. PVA TePla can provide 2 kinds of crystal growth method, including high-temperature chemical vapor deposition (HTCVD) and high temperature sublimation method (HTCVT, also known as PVT method). Both equipment are suitable for academic and R & D institutions.

  3. Graphite Manufacturing:
    • Purification
    • Increasing raw material prices and increasing requirements of the purity of materials enable new applications。
    • Graphitization
    • PyC-coating
    • SiC Coating
    • Silicon carbide (SiC Coating) coatings are widely discussed in recent years. However, this technology is still being held by a small number of companies. Our clients include international graphite manufacturers, and they use our furnaces to provide high quality silicon carbide coating components to customers in semiconductor, LED and solar industries.
