UHV Heater Systems – An Introduction:
In Ultra High Vacuum (UHV) Heater systems, space is a precious commodity. Within these systems, various components are often required for critical processes such as measurement, deposition, or sample manipulation. When the need arises for high-temperature heating, a common concern is whether a Sample Heater can be effectively integrated into the limited space within the chamber. Thermic Edge addresses this challenge with its range of compact, high-performance PG/PBN heaters. These heaters are designed specifically for applications where space is at a premium, offering an elegant solution that does not compromise on performance.
The PG/PBN Heater Design
The PG/PBN heaters combine two key materials—Pyrolytic Graphite (PG) and Pyrolytic Boron Nitride (PBN)—to create a thin yet powerful heating element. At just 2mm thick, these heaters can achieve temperatures up to 1500°C in non-oxidising environments, making them well-suited for demanding high-temperature applications. The combination of PG and PBN not only ensures excellent thermal performance but also offers chemical inertness, providing resistance to corrosive gases that may be used within the system or that may be released from heated substrates.
One of the most notable features of this design is the integration of PBN layers on both sides of the PG circuit, which serves to electrically isolate the heater from the surrounding components. This characteristic makes the heater both safe and reliable, even in sensitive environments where precise control is essential.
Efficiency and Durability
A standout advantage of the PG/PBN heaters is their fast ramp rate and low thermal mass. This means that they can heat up quickly and, importantly, cool down just as fast. For laboratories where time is of the essence and throughput is crucial, these heaters contribute to significantly reducing downtime, enabling quicker cycling between experiments or processes.
In addition to their efficiency, these heaters are built for durability. The robust construction allows for tight tolerances in the heater design, ensuring that they can be manufactured to precise specifications. This is particularly beneficial for applications that require bespoke sizes or specific orientations of the heater, such as those involving unusual or challenging geometries.
