Model 1495D Vacuum Oven / Station

Vacuum ovens are used for a wide variety of vacuum drying curing, and moisture content testing. Common applications include drying heat sensitive samples, moisture determination, and drying samples under a controlled atmosphere. SHELLAB vacuum ovens are specifically designed for unparalleled performance when utilized for these, and other applications.

The Model 1495D is a general-purpose vacuum oven specifically designed for professional and industrial use. The most salient feature of this oven is its size: 9 cubic feet (255 litres). The oven is secured to a ruggedly constructed modile stand, thus creating a vacuum station. The stand is designed for mounting a vacuum pump at the base. Althought the oven is not supplied with a vacuum pump, all vacuum plumbing and KF25 connections are provided. Stainless steel is used for all vacuum tubing and connections.

A digital vacuum gauge, mounted in the control panel, shows the chamber vacuum level in measurements of Torr and m/Torr. Although this gauge has the capacity to act as controller, in this application it functions only as a gauge with display. The display range is 760 Torr down to 0 mil Torr.

The microprocessor based main temperature controller offers multiple ramp and soak capabilities. The WATLOW 981 programmable controller is capable of storing and running up to 24 steps of ramp and soak temperature profiles. A secondary, and completly independant. High Limit controller provides overtemperature safety protection. All controls are easily adjustable at the control panel.

Since there is no air in the vacuum chamber, heat is transfered from the heating elements to the interior chamber wall, then to the shelves, and finally to the samples. To minimized conductivity resistance, aluminum shelves are provided. The oven chamber is wrapped in high temperature insulation, which aids overall performance and promotes energy efficiency. All stainless steel construction, true vacuum valves, and cross-flow ventilation through the oven chamber aid overall performance.
