Thermal Barriers

PhoenixTM develops Thermal Barriers to suit specific applications; for example coating processes require Thermal Barriers to be free of all traces of silicone, whereas in the heat treatment industry, where Thermal Barriers are subject to high rates of heating and cooling, minimizing Thermal Barrier distortion is the main criteria. In other processes such as heat treating aluminum road wheels Thermal Barriers need to withstand full immersion in water from a high temperature. PhoenixTM can also design Thermal Barriers to meet specific process conditions, such as steel reheat processes which require graded insulation layers to withstand the 2370°F temperatures within the furnace. The many years experience of senior PhoenixTM personnel working within these industries is translated into the superior design of their Thermal Barriers for all heat treatment and finishing applications.

TS04 Thermal Barrier


-238°F to 570°F

Specifically designed for the finishing industry, the PhoenixTM TS04 Thermal Barrier range offer ease of handling and high thermal performance in a compact design. They are designed to accept the PhoenixTM 6, 10, and 20 channel Data Loggers, and being built from silicone-free materials they are ideal for use in the automobile industry. PhoenixTM can also design Thermal Barriers for longer duration processes or where water spray may be part of the process.

TS08 Thermal Barrier


up to 1290°F

Built for brazing aluminum radiators and condensers for automobile air conditioning and cooling systems, these thermal barriers are designed to protect the data logger against the harsh conditions inside the brazing furnace. Oxygen presence within the thermal barrier is reduced by maximizing the amount of nitrogen in the insulation material. This minimizes the possibility of oxygen contamination in the furnace. The TS08 thermal barriers have also been designed with no insulation exposed to the furnace atmosphere. This ensures it can resist acid attack, a common problem in CAB processes, and therefore extends the life of the barrier and reduces maintenance costs.



32°F to 1470°F

Developed for processes up to 1470°F the PhoenixTM TS01 Thermal Barrier range is perfect for applications in the aluminum, glass and steel industries. Microporous insulation and a 'latent heat accumulator' or heat sink provide protection against the temperatures inside of the furnace. Made from high grade stainless steel, with an easy to replace thermocouple wear strip, the TS01 range is robust and durable. Special designs are also available for non-standard applications.

TS02 Thermal Barrier


32°F to 1830°F

Processes such as carburizing at temperatures up to 1830°F, demand a Thermal Barrier which can withstand severe changes in temperature, pressure, and aggressive atmospheres. Strengthened and reinforced at critical points to minimize distortion, PhoenixTM TS02 Thermal Barriers are designed to offer full protection to the Data Logger in these demanding conditions. TS02 barriers are also fitted with extra heavy duty catches, dual thermocouple exits and user replaceable thermocouple wear strip to help extend the life of the thermal barrier in these harsh environments and reduce the need for costly repairs. Special designs can be constructed for non standard applications.

TS06 Thermal Barrier


32°F to 2010°F

Built for solution treatment and age hardening where high temperatures and water quench are part of the process, the PhoenixTM TS06 Thermal Barriers are designed to offer maximum protection to the Data Logger from these conditions. These Thermal Barriers use the principle of evaporating water to keep the Data Logger cool in the furnace, and can re-fill in the quench to allow it to undergo a further heating period as is normal in aluminum or stainless steel solution treatment. During the quench a water tight seal is maintained by using heavy duty seals and stainless steel compression glands around the thermocouples, this affords maximum protection to the data logger.

TS07 Thermal Barrier


up to 2370°F

Developed for high temperature long duration steel slab and billet reheat processes. Manufactured from the highest specification material and using graded insulation layers, the TS07 range accepts 10 and 20 channel data loggers and is designed for repeated use at temperatures up to 2370°F. For ease of assembly and logger removal the TS07 features a data logger holding tray with integral thermocouple securing clamps.

TS05 Thermal Barrier


up to 660°F

Developed for the ceramic industry, the PhoenixTM TS05 series Thermal Barriers travel beneath the kiln car for a sustained period at moderate to high under car temperatures. Built from high grade stainless steel these Thermal Barriers use evaporative water technology to keep the Data Logger cool and protect against mechanical damage and the dusty environment of a ceramic kiln. These thermal barriers have detachable thermocouple sockets which can be mounted remotely from the thermal barrier for easy thermocouple fitting.

TS14 Thermal Barrier


-40°F to 480°F

Processes within the food industry such as deep fat frying, steam cooking, chilling and blast freezing, at temperatures from -40°F to +480°F, demand a thermal barrier which can withstand severe changes in temperature, and full immersion in hot oil, or water while affording maximum protection to the data logger. Features of the thermal barrier include silicone bungs to seal around the thermocouples, integral retaining plates to secure the bung position, and a special 'O' ring recess to prevent face plate distortion. Special designs are also available for non-standard processes.

Ganzer Behaelter freigestellt


up to 1000°C

The PhoenixTM TS12 Series Thermal Barrier (Patent Pending GB1509136.6) for oil quench processes uses a two part insulation system: The inner thermal barrier is completely sealed to prevent oil contaminating the data logger. The outer insulation layer provides additional heat protection in the furnace. The system is designed not only to go through the complete heat treatment cycle including the oil quench, but has enough thermal capacity to go through a wash cycle afterwards.
