Thermal Barriers

4900 Series Thermal Barriers

Uniquely designed for exceptional durability and thermal resistance. Made entirely of high quality 310 stainless steel and featuring Floating PlateTM technology, these long lasting barriers resist oxidation and distortion better than ever before.

The 4900 series of barriers are ideal for applications such as annealing, aluminum or stainless steel brazing, frit sealing and annealing, and steel heat treatment processes.

 

Highlights

  • Operating temperature up to 1050°C / 1900°F
  • 310 stainless steel construction (including fasteners) for the best resistance to oxidation at extreme temperatures
  • Floating Plate™ technology minimizes distortion, essential if clearance is limited, and helps alleviate cracking of insulation
  • Securely welded sturdy 310 stainless steel handles ensure safe handling when hot
  • One way lid and base alignment avoids thermocouple damage
  • User replaceable mullite textile wear strips minimize maintenance costs
  • Rounded edges on barrier lid and base alleviate effects of thermal stress
  • Environmentally safe mullite textile barrier lining
  • Optional stand to avoid distortion, i.e. due to differential thermal contraction if a hot barrier is placed on a cold floor

4000 Series Barriers

These barriers work in two stages to keep the logger at a safe working temperature as it travels through the process. Microporous insulation slows down the passage of heat. The second insulation stage features a unique heat sink with phase-change material that maintains an internal temperature of 58°C (136°F).

Highlights
  • Operating temperature up to 850°C / 1560°F
  • Rugged 304 stainless steel construction
  • Microporous insulation provides the best thermal protection of any known material
  • Various heights available to meet limited clearances
  • Wear strips minimize maintenance costs
  • Environmentally preferred mullite textile barrier lining
  • Optional stand to avoid distortion, i.e. due to differential thermal contraction if a hot barrier is placed on a cold floor

Reheat Thermal Barriers - Slab or Billet
Datapaq's proven technology uses a phased evaporation thermal barrier with integral graduated insulation layers, surrounded by an Alumina or ceramic fiber blanket insulation. This keeps the data logger at a safe working temperature. It is all contained in a high grade Nicrobel insulation frame.
Highlights
  • Low thermal barrier height for low clearance furnaces
  • High thermal capacity to cope with stoppages that frequently occur
  • Phased evaporation technology allows long duration
  • Floating PlateTM construction minimizes distortion
  • Rugged high grade stainless steel resists high temperatures
