Carbolite HVTT 1200C and HVTT 1500C Vacuum Tube Furnaces. A total of five models make up the range. 10-5 mbar is achievable using a vacant tube. All are floor standing furnaces, forming a base from which bespoke customer designs can be developed in order to meet specific application requirements.
1200C models are heated by a integral wire wound work tube. The 1500C models use parallel installed Silicon Carbide elements. Supplied with Carbolite Gero 301 digital PID controller, with inbuilt process timer and one ramp rate.
