Energy Saving Single-Chamber Vacuum Tempering Furnace Low Maintenance Heat Treatment Furnace

Single-chamber vacuum tempering furnace is compact integrated vacuum heat treatment equipment, all heating, soaking and gas cooling processes are completed inside one single sealed vacuum chamber. Without separate transfer chamber, it saves workshop space and reduces equipment investment cost, widely used for bright tempering after quenching, stress relieving and aging annealing of metal workpieces.

Working under high vacuum or inert nitrogen/argon atmosphere, it totally isolate oxygen and moisture, prevent oxidation & decarburization on workpiece surface. Treated parts keep original bright metallic finish, no secondary polishing or blasting needed. Equipped with forced convection heating system, temperature uniformity reaches ±5℃ inside full working zone, effectively eliminate internal stress and avoid temper brittleness, stable mechanical performance for every batch products.

1.Bright Oxidation-Free Workpiece Surface High vacuum sealing structure cuts off air contact, no oxide scale or discoloration after tempering, save post-processing cost of sandblasting & pickling.

2.Uniform Temperature Field, Stable Heat Treatment Quality Forced circulation convection fan ensures tiny temperature difference inside chamber, consistent hardness & toughness for mass production, meet high-standard precision part manufacturing demand.

3.Compact Single Chamber Design, Space Saving All processes finished in one vessel, floor area only half of double-chamber furnace, perfect for small & medium heat treatment factories.

4.Fully Automatic Intelligent Control, Labor Saving PLC touch screen control system, store dozens of heat treatment recipes, auto run full cycle without manual operation. Support real-time curve recording & data export for quality traceability.

5.Energy Saving & Low Maintenance Cost Multi-layer metal heat shielding structure reduces heat loss by 20%, heating elements and vacuum spare parts are easy to replace for overseas after-sales service.

6.Full Safety Interlock System, CE Certified Door lock interlock, over-temperature power cut, water shortage protection, over-pressure relief and fault alarm system, comply with EU industrial safety standards.

Q1: Single chamber vs double chamber furnace, which one to choose?

A1: Single chamber is more cost-effective for small & medium batch production, limited factory space and tight budget. Double chamber fits mass 24h continuous production and ultra-high anti-oxidation requirement.

Q2: Do workpieces need polishing after tempering?

A2: Parts treated under high vacuum & pure nitrogen atmosphere keep bright metallic surface without oxidation or discoloration, only simple cleaning required, no sandblasting or polishing needed.

Q3: Can the furnace be customized for export? Can I change chamber size & voltage?

A3: Full customization available: chamber dimension, max temperature, vacuum system, imported PLC brand, industrial voltage 220V/380V/415V for EU & Southeast Asia, remote monitoring module optional.

Q4: What about sea packing & warranty service?

A4: Machine packed with vacuum moisture-proof film & fumigated wooden case for ocean transport. 12 months full machine warranty, permanent spare parts supply, English operation manual, remote installation guidance.
