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).

Operating Instructions

Temperature Controller Panel

Description of Controller Panel Keys

1. Press and hold the key for 3s or more to control the run/stop of the program.
2. In the setup mode, press this key to add one number and hold the key to increase numbers successively.
3. In the setup mode, press this key to decrease one number and hold the key to decrease numbers successively.
4. Return.
5. Set the target temperature and enter the internal parameter layers

Functions

• F1: first layer measurement temperature
• F2: second layer measurement temperature
• F3: third layer measurement temperature
• F4: fourth layer measurement temperature
• RUN/STOP: display of running status
• 14: 09: time display of controller system
• SET: display of set value. (°C: display of temperature unit symbol)

Priming the Vacuum Pump

• Priming of the vacuum pump requires that the connecting tube provided is securely (airtight sealed) placed between the vacuum pump and the vacuum oven.
• The oven door should be securely shut, and the door handle secured in a closed position (this will prevent air from entering the chamber by causing the hole in the rubber plug and the hole in the pipe core to be 180 ° out of phase).
• Power to the vacuum pump should be turned on and then the vacuum valve should be closed by turning the handle clockwise 90°during processing.
• To stop the process, reduce the vacuum in the chamber -0.1Mpa before turning off the vacuum pump. This will ensure that no engine oil from the vacuum pump will be drawn into the chamber.

Priming the Vacuum Oven

• Turn on power to the vacuum oven (a power-on indicator light will confirm this) and after a 5 second self-test is completed; the temperature controller will automatically enter the “run” mode. This will allow the PV screen to display the process temperature and the SV screen display the set temperature.
• Once the process begins the AT indicator light will turn on and if process temperature is less than the set temperature heating lamps will turn on.

Setting of Temperature

• When the instrument is switched on, press the button one time, and the “set temperature value” will start to blink. Set the desired temperature value (in Celsius degrees) by pressing keys.
• Use the button to move between the digits.
• Confirm the set value by pressing the button.

Note:
Pressing the ‘ or ’ key once changes the value by 0.1. Press and hold the keys changes the value rapidly.

Start / Stop Operation

• After setting the operating parameters, press button for 4-5 seconds to start the heating process. When the word “STOP” appears on the upper right corner of the screen, the system is in the stopped state. When the message “RUN” appears in the upper right comer, the system is in the running state and the screen will display values like timer, temperature measured inside the chamber.
• At any time, you can always manually stop running by pressing the button for 4-5 seconds.

Setting the Deviation Alarm and Timer

• On the controller panel, press and hold the key for 4-5 seconds.

• 

• Press key to confirm, press or key to move, press key to return.
  

• TIMER WAIT: ON/OFF of waiting temperature. When ‘ON’ the waiting temperature is available. When ‘OFF’ no waiting temperature is available.

• ALM Temp: Setting of temperature deviation alarm: when the measured temperature > set temperature +ALM TEMP, an audible alarm will sound.

• RH Temp: Setting of the upper limit for Temperature Control.

• Timer: When the time is set as 0, timing function is not available. When other than 0 is applied the controller is in ‘Timer’ function.

Press the key so, that Timer numerical value is back lit displayed, indicating the timer can now be set as required, by pressing either the or key.

NOTE: If no operation is performed for a long time, the system automatically returns to the home screen.

Setting the Pre-set Start Function

• Press and hold the key and press key, then shift the cursor to ‘START SETUP’, and press key.

NOTE: The parameters here are factory parameters, do not adjust (except for the system date and password)

Unit, SYSTM Timer and PASSWORD Settings

• Unit:” 0” ℃，”1” ℉
• YY: year; MM: month; DD: day; HH: hour; MM: minute; SS: second; (this is the apparatus system time setting)
• PASSWORD: for direct input and changing of new password.
  

Cautions

• Combustible materials and corrosive liquids or gases should not be placed in the vicinity of the drying cabinet.
• If the product is excessively damp before drying, add a “precipitation” filter between the vacuum pump and the cabinet to avoid steam entering the pump.
• If a granular product is to be dried, a 5 ?m filter should be added in series before the vacuum intake.
• If the air release rubber stopper becomes difficult to turn, Vaseline may be used to lubricate the contact area.
• The vacuum chamber should always be clean. The glass on the cabinet door should only be cleaned using a soft cotton cloth.
• Whenever the vacuum cabinet is not used for a prolonged period of time, it is recommended that all exposed plated parts be cleaned by nonabrasive lubricant. It is recommended that a plastic film cover be placed over the cabinets to prevent dust from accumulating.
