High-Temperature Processing Vessels
Roben, Mfg, Inc. engineers and fabricates high-temperature processing vessels, delivering jacketed pressure vessels designed for manufacturing operations at temperatures from 200°C to 500°C and beyond using thermal fluids, molten salts, or electric heating systems. Our high-temperature processing vessels combine appropriate materials for elevated temperature service, efficient high-temperature jacket designs, and thermal management systems that achieve and maintain extreme temperatures for polymer processing, specialty chemical synthesis, and advanced material manufacturing.
What Are High-Temperature Processing Vessels?
A high-temperature processing vessel is a jacketed pressure vessel specifically engineered for processing operations at temperatures above 200°C, incorporating materials qualified for elevated temperature service, jacket designs optimized for high-temperature heating media, and thermal management systems that efficiently deliver and control extreme temperatures. These vessels may utilize high-temperature thermal fluids (Dowtherm, Therminol), molten salts, or electric heating elements depending on temperature requirements and process needs. High-temperature processing enables polymer melt processing, certain chemical syntheses, and material treatments impossible at conventional temperatures.
Why Choose High-Temperature Processing Vessels?
High-Temperature Processing Vessels offer several critical advantages for thermal processing:
- Extreme High Temperatures: Achieve processing temperatures to 500°C and beyond
- Unique Processing: Enable reactions and treatments only possible at elevated temperatures
- Polymer Processing: Melt and process high-performance polymers and composites
- Material Treatment: Heat treat, cure, and condition advanced materials
- Process Intensification: Higher temperatures often accelerate reactions and reduce cycle times

Frequently Asked Questions About High-Temperature Processing Vessels
What temperature ranges can high-temperature processing vessels achieve?
High-temperature processing vessels achieve temperatures from 200°C with standard thermal fluids to over 500°C with specialized thermal fluids, molten salts, or electric heating systems. Maximum temperature depends on materials of construction and heating system selection.
What heating media are used for high-temperature processing?
Heating media options include high-temperature thermal fluids (Dowtherm A to 400°C, Therminol 75 to 385°C), specialized synthetic fluids (to 450°C), molten salts (to 550°C), and electric heating elements. Selection depends on temperature requirements, heat transfer rates, and operational preferences.
How are thermal expansion stresses managed at high temperatures?
High-temperature vessels incorporate sliding supports, expansion joints, and carefully designed attachment points allowing the inner vessel to expand independently from the outer jacket and support structure. Bellows-sealed penetrations accommodate differential movement at nozzle connections.
