High Temp SUS310S Water Cooling Jacket for Heat Treatment Furnace

Water Cooling Jacket is a core temperature control component for industrial high-temperature heat treatment furnaces. It adopts an integrated welded double-wall hollow interlayer structure. The inner wall closely fits the high-temperature heating chamber, while the interlayer forms a sealed circulating water channel. Continuous cooling water flows through the channel to take away excess heat, stabilize the outer surface temperature of equipment, protect vacuum seals and furnace body structure. It is an essential cooling accessory for vacuum furnaces, mesh belt heat treatment furnaces, quenching furnaces and salt baths.

✓ Quenching Furnace       ✓ Tempering Furnace
✓ Glass / Ceramic Kilns    ✓ Heat Treatment Furnaces

1. Double-wall pressure shell: high-temperature resistant inner steel plate + load-bearing outer plate

2. Precision circulation channel: spiral / straight water channel for full heat exchange

3. Standard inlet & outlet port: thread / flange connection for industrial cooling pipelines

4. Full penetration welding seal: airtight welding to prevent water leakage

5. Integrated mounting flange: directly matched with furnace door, furnace barrel and chamber

1. High-efficiency constant temperature cooling: large-area water channel heat exchange, furnace outer surface temperature stable below 50°C, avoid thermal deformation & scald risk

2. Vacuum seal protection: isolate ultra-high furnace temperature, prevent seal aging and vacuum leakage

3. Extend furnace service life: reduce thermal fatigue & crack risk of furnace shell, cut maintenance cost

4. Leak-proof airtight welding: full welding + hydraulic pressure test under 0.6–1.0MPa, no water seepage under vacuum

5. Anti-corrosion material: SUS304 / SUS310S stainless steel optional, resistant to heat treatment fume & cooling water scale

6. Full customization support: round, square, rectangular & special-shaped furnace door jackets, OEM & ODM based on drawings

7. Stable for mass production: suitable for 24h continuous operation of mesh belt furnaces, carburizing furnaces, bright annealing furnaces

1.Heat Treatment Equipment: vacuum quenching furnace, mesh belt carburizing furnace, bright annealing furnace, tempering furnace, salt bath tank

2.Auto & Medical Hardware: cooling structure for auto fastener, bearing & medical device heat treatment lines
