USED HARPER VERTICAL SLOT FURNACE

(2 Available) Unused 40 Meter High Vertical Slot Furnace, Max. 2000 deg. C:
Harper develops vertical furnace systems — often called vertical conveyor furnaces or vertical calciners — for industrial thermal processing. These are continuous furnaces designed to move material vertically through different thermal zones rather than horizontally like many traditional furnaces.

- Continuous vertical material movement through heat zones.
- Enhanced heat/mass transfer and process uniformity.
- Designed for high-temperature reactions with improved efficiency.
- Designed to provide long residence time — meaning material takes long enough to undergo the full thermal cycle.

Ideal industrial application for:
Powder processing - carbides, borides, nitrides, refractory metal powders.
Advanced material reactions - controlled oxidation, reduction, pyrolysis, carburization, etc.
Carbon fiber or ceramic fiber heat treatment - often part of lines for oxidation, carbonization, or graphitization.
High-temperature specialty processes - where the uniform thermal environment and movement of material enhance yield and quality.

Built in modular sections: multiple heating zones can be stacked vertically to handle different temperature profiles efficiently.
Tailored for continuous processing at high throughput, suitable for large-scale industrial production.
