Hephaestus V094/V213 Vacuum Ovens
– Introduction
The Hephaestus V vacuum ovens are designed to efficiently process raw materials in a
temperature controlled vacuum environment. This process has the following advantages:
•
The partial vacuum decreases the boiling point of water and thereby decreases the process
temperature and increases the rate of moisture evaporation.
•
The reduced processing temperature minimizes the oxidation rate of the product ensuring
less oxidative damage.
The Hephaestus V Vacuum Oven is constructed from 304 stainless steel and the exterior
surface of the oven is polymer coated. The inner chamber uses either a galvanized or a
stainless-steel armour plate. Fiberglass insulation is used to thermally insulate the chamber.
The cabinet door has a viewing window that allows visual inspection of the process. The window
is constructed using a double-layered fortified glass design. The door uses a heavy-duty column
door pin.
Temperature is monitored and controlled using a Pt100 sensor and a temperature controller.
The temperature controller allows the output power with to be controlled using a PID. It also
monitors the process temperature and corrects temperature fluctuations and monitors
processing time(s).
