Description

Introducing the new Ai 18-shelf capacity 5 sided wall-heating 7.5 cu ft vacuum ovens, come standard with secondary over-temp protection dial, stainless steel tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, and two year warranty.

SST (stainless steel) tubing refers to internal tubing and compression. external tubing not included. Oven comes standard with 9 shelves. This unit only comes in 220V 50/60Hz.

New low proportional controller technologies result in:

  • Excellent uniformity
  • Accurate temperature settings
  • Super-fast heating rates
  • Minimum heat loss
  • and very low power consumption

Every one of Ai’s vacuum ovens goes through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving our warehouses.

Note: Contact us for accurate lead time and freight shipping cost. Web orders may not calculate correct shipping. Shipping costs will be confirmed after order placement for any items shipping by freight carrier.

Ai 7.5 CuFt Vacuum Oven Features

Every one of our vacuum ovens goes through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving our warehouses.

  • ETL tested to UL and CSA standards
  •  Chamber Size: 22 x 23.5 x 25″ Material: Stainless steel Capacity: 7.5 cubic feet
  • New KF25 inlet filter keeps your oven clean at all time (included with oven purchase).
  • All stainless steel internal tubing provides higher ultimate vacuum, holds vacuum 10 times longer, and require minimum maintenance.
  • Oil-filled mechanical vacuum gauge provides more accurate reading, longer gauge life and minimizes shipping damage. Digivac recommends adding either a Bullseye Vacuum Gauge or a vacuum controller like the SNAP for optimal and more uniform vacuum drying between batches. See the benefits of adding vacuum regulation here
  • 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 within +/- 1F accuracy, in either F or C.
  • 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″ tempered safety glass.
  • 3″ thermal insulation prevents heat loss and minimizes the enclosure’s outer surface temperature.
  • 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.
  • Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
  • Built-in swivel casters with leveling feet.
  • 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.

Manufactured in accordance with

  • UL 61010-1
  • CSA C22.2
  • ISO 9001:2000
  • ISO 12100-1:2003, ISO 12100-2:2003
  • EN1050:1996, EN294:1992, EN60204-1:2006

IMPORTANT! NEVER LEAVE YOUR OVEN UNATTENDED WHILE OPERATING. Across International or DigiVac is not responsible for any loss of material inside of the oven.

An extra shelf for this oven can be found here.

DIGIVAC Recommends

Vacuum Pumps:

Vacuum Control: VPC with VPPM Software for running recipes or RAMP control or the SNAP controller that has onboard recipe control

  • Optimize your process by adding Automated Vacuum Control: Add the SNAP Vacuum Controller to Automate and Optimize your vacuum drying process. Vacuum Controller with onboard ramp rate recipe control. Set up to 8 recipes based on time and pressure setpoints. Treat material in chamber more gently by implementing kinder ramp rate controls which is ideal for freeze drying, vacuum drying or lyophilization applications
  • SNAP with DPCP:  The SNAP millitorr automated vacuum controller provides precise vacuum control and venting in one device from 750 Torr down to 50 millitorr. Easily control your vacuum process and venting with the touch of a button or the twist of a knob with the SNAP (Simple, Nimble, Automatic Process Controller).

Benefits of Vacuum Control on Vacuum Ovens:

Vacuum ovens in general offer a more gentle way to dry things.  Adding vacuum control builds on these vacuum drying advantages by:
  1. Providing precise control to the drying process enabling a more repeatable drying process and drying result
  2. Slowing down the initial pumpdown of a vacuum drying process helps do 2 things: ensures lighter materials are not sucked into the vacuum pump and ensures more delicate materials are not put under undo molecular stress
  3. Enabling the sequential separation of components to be removed while leaving others like in the example of residual solvent evaporation (Different solvents have different boiling points)
Advanced drying techniques typically employ different recipes of both temperature and pressure set points.

VPPM software combined with the Vapor Pressure Controller (VPC) allows you to set up a profile for your vacuum system, determining when it holds pressure or ramps up/down. Additionally, this software allows you to set a timeframe, in seconds, of how long each case occurs.

For multiple vacuum oven control with one vacuum controller consider the Concerto. The Concerto vacuum controller can control up to 4 vacuum ovens with one pump. Need recipe control for one vacuum oven? Choose the SNAP. We would recommend the IDP15 for controlling multiple vacuum ovens with the Concerto.
