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 Plate™ 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

4500 Series Thermal Barriers

Built with furnace survey operations in mind, the Datapaq 4500 Series thermal barriers have been designed to operate at high temperature, through repeated heating and cooling cycles giving maximum protection to the data logger.

TheTB4500 series barrier incorporates several new design features including additional strengthening at critical points, removable gas quench deflector shields and taper lock catches.
 

Highlights

• Taper lock catches ensure easy and positive locking and unlocking of the barrier lid to the base. Eliminates the need for threaded catches, which may be prone to high temperature seizure.
• Barrier strengthening at 8 points on both lid and base minimises barrier distortion at critical points ensuring a positive barrier seal for maximum protection of the data logger.
• High quality Stainless Steel casing for maximum protection in carburizing atmospheres.
• Removable Quench Deflector Shields to minimize barrier distortion during rapid cooling periods.
• Gas flow venting through insulation layers and heat sink holders to instantly equalize pressure during a gas quench to prevent internal barrier damage.
• Heat sink pressure lock filler points to prevent damage through pressurizing.

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

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 Plate™ construction minimizes distortion
• Rugged high grade stainless steel resists high temperatures
