AT Series 250C UL Certified Vacuum Ovens

Overview

The new UL certified 3.2. cu ft vacuum oven comes standard with secondary over-temp protection dial, stainless steel internal tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, and two year warranty. With our new internal shelf heating technology, each shelf in these ovens has its own heater, in-shelf temperature sensor and temperature controller, together with great thermal-conductive aluminum and our new low proportional controller technologies, the result is perfect uniformity, accurate temperature, super-fast heating rates, minimum heat loss/exterior temperature and very low power consumption.

The Ai 5.0, 7.5, and 16 cu ft vacuum ovens, come standard with secondary over-temp protection dial, stainless steel internal tubing, stainless steel vacuum & vent valve, oil-filled and vacuum gauge.

All AI vacuum ovens go through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving their warehouses.

Features:

• The 3.2 cu ft AT32x comes with 6 shelves (12 shelf capacity) in 110V 50/60Hz
• The 5 cu ft AT50x comes with 7 shelves (14 shelf capacity) in either 110V or 220V 50/60Hz
• The 7.5 cu ft AT75x comes with 9 shelves (18 shelf capacity) in 220V 50/60Hz
  
• The 3.2 cu ft AT32x comes with 13 shelves (26 shelf capacity) in 220V 50/60Hz
•  The new KF25 inlet filter keeps your oven clean at all times (included with oven purchase).
• All stainless steel internal tubing provides a higher ultimate vacuum, holds the vacuum 10 times longer, and requires minimum maintenance.
• Oil-filled mechanical vacuum gauge provides more accurate reading, longer gauge life and minimizes shipping damage.
• All stainless steel vacuum and vent valves gives you cleaner connection, more accurate control and long term durability.
• 4th gen low proportional gain temperature controllers keep your oven temperature accurate
• Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
• A vacuum environment lowers the boiling point (great for processing heat sensitive materials) and reduces drying time for materials like paste or powder which cannot otherwise be easily dried.
• Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time.
• Dual layer observation window with 3/4" (5/8” for the AT32x) tempered safety glass.
• Built-in swivel casters with leveling feet.
• Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
• For improved temperature ramping, run the auto-tune procedure as outlined in the manual.
• All ovens shipped from our New Jersey or Nevada location for quick delivery.
• 2-year warranty and lifetime US-based parts and service support.
• Guaranteed US based phone and email assistance from an Ai support engineer within 30 minutes.
  

Attention: Before initial use, run oven at 200C/400F without vacuum for 15 minutes to burn off any residue that may have been introduced during the manufacturing process. NEVER LEAVE YOUR OVEN UNATTENDED WHILE OPERATING. Across International is not responsible for any loss of material inside of the oven.
