BIOSTELLAR Explosion-Proof Forced-Air Drying Oven

• Four chamber capacities
  Choose from 65, 125, 230 and 625 L versions according to sample dimensions, batch size and available installation space.

• Forced-air circulation
  Model-specific air-duct arrangements circulate heated air through the chamber. The airflow design varies with capacity.

• PID temperature control
  An LCD controller displays measured and set temperatures. Temperature resolution is 0.1°C, with specified temperature fluctuation of ±1°C.

• Stainless steel working chamber
  The mirror-finish stainless steel interior and pull-out shelves support chamber cleaning and sample access.

• Explosion-protected heating and electrical components
  The documentation specifies explosion-protected 304 stainless steel heating tubes, an armoured Pt100 sensor and protected external wiring connections.

• Flexible operating modes
  Fixed-temperature operation, timed operation, automatic stop and scheduled start accommodate different drying schedules. Power-failure memory retains stored settings.

• Control protection and configuration options
  Over-temperature alarm, temperature-limit protection and menu locking are listed. Program control, a 7-inch touchscreen controller and a pressure-relief door are optional.

1. Which chamber sizes are available?
The series has four nominal capacities: 65, 125, 230 and 625 L. Select the version using both chamber dimensions and the space needed around the load for airflow.

2. What does “ambient +10°C to 300°C” mean?
The stated lower operating limit is 10°C above ambient temperature. The 300°C upper limit must be checked against the approved conditions for the intended installation and process.

3. Is 0.1°C the temperature accuracy?
No. The documentation identifies 0.1°C as temperature resolution and ±1°C as temperature fluctuation. These are separate specifications.

4. Does the oven support automatic timing?
Yes. Timed operation, automatic stop and scheduled start are listed alongside fixed-temperature operation.

5. What shelves are supplied?
The document lists two shelves and four shelf supports. Shelf load capacity is stated as 15 kg; the number of shelf positions varies by chamber size.

6. What electrical supply is required?
The 65, 125 and 230 L versions are listed at AC 220 V; the 625 L version is listed at AC 380 V. The table specifies 50/60 Hz. Confirm the final nameplate and wiring requirements before ordering.

7. Are touchscreen and programmable operation standard?
No. The standard specification describes an LCD controller with four-button setting. Program mode and the 7-inch touchscreen controller are optional.

8. What explosion-protection information is available?
The supplied sheet states Ex d e mb IIB T4 Gb. Certificate scope, installation conditions and sample compatibility require confirmation. The sheet alone does not establish ATEX/IECEx certification or suitability for unrestricted solvent evaporation.

• Controlled drying in petroleum and chemical laboratories.
• Laboratory drying work in pharmaceutical and medical research settings.
• Scientific research requiring forced-air heating and scheduled operation.
• Industrial laboratory drying where the sample, installation and explosion-protection requirements have been assessed.
