The Carbolite Gero EHA 12/450 is a compact, single-zone horizontal tube furnace precision-engineered to deliver highly reliable and precise thermal processing for advanced academic research, materials testing, and industrial quality control laboratories. Reaching a maximum operating temperature of 1200 °C, this model utilizes high-performance radial wire elements embedded seamlessly inside a vacuum-formed insulation matrix. This optimized thermal shielding design guarantees rapid heat-up rates (reaching top temperature in just 44 minutes), elite uniform temperature distribution, and exceptionally short cool-down periods.
A primary advantage of the EHA 12/450 is its modular architecture, as it does not include a fixed, built-in work tube. By utilizing optional interchangeable tube adapters, technicians can introduce various quartz or ceramic work tubes with an outer diameter up to 60 mm into the same furnace. This configuration effectively insulates the internal heating coils from aggressive sample outgassing, leakage, or chemical cross-contamination, greatly extending the operational life of the device. Precise thermal loops are piously governed by the industry-proven Carbolite Gero 301 digital PID controller, featuring single-ramp control to setpoint, automated delayed start, and integrated process timing as standard.
Flexible & Interchangeable Tube System: Built without a fixed internal work tube; allows for different quartz or ceramic tubes up to 60 mm outer diameter to be used in a single unit via modular adapters.
Advanced Radial Heating Element Design: Wire elements embedded directly into vacuum-formed insulation layers enable quick heat-up cycles (44 minutes) and reduced cooling intervals.
Core Element Shielding: Running tests with an independent, removable work tube ensures the furnace's heating coils remain clean and fully protected against outgassing or chemical scaling.
Atmospheric Control Adaptability: Compatible with longer work tubes (up to 900 mm) equipped with gas-tight end seals and flanges for processing under high vacuum or modified gas atmospheres.
Intuitive Digital PID Controller: Features the Carbolite Gero 301 digital controller as standard, supporting smooth single-ramp heating profiles, digital process timing, and automated delayed start functions.
Ergonomic Benchtop Layout: The horizontal furnace body is stacked neatly above the integrated power and control enclosure, ensuring a space-saving and rigid laboratory footprint.
