2. Forced Air Circulation Systems
All walk-in rooms incorporate forced air circulation. Differences in the size of the test chamber and its internal configuration are accommodated by various airflow patterns, including horizontal, vertical, or a combination of both. These provide an even distribution of air and tight temperature control. Noise is also a consideration.
The air circulation systems use external heavy duty motors to distribute air evenly and constantly recirculate it, maintaining uniform and accurate temperatures and humidity. The high quality motors have internal cooling fans, protectors, and stainless steel shafts. Aluminum or stainless steel squirrel cage blowers circulate the air. All mixing is within a plenum that is external to the walk-in room work area.
In tight tolerance environmental walk-in rooms, air must be evenly distributed and constantly recirculated at a higher than normal rate in order to maintain uniformity and accuracy. A portion of one wall of the room is devoted to a conditioning plenum. Air is drawn into the lower part of the plenum through a set of cleanable filters, across an evaporator coil and vertically across electric heaters. The air then enters centrifugal fans and is discharged into a perforated ceiling plenum. The air flows vertically downward in the room and is returned horizontally through the cleanable filters to the wall plenum.
3. Electric Heating System
The combination of airflow, instrument response, and fast-reacting heaters provides very accurate and straight line control of temperatures.
Air is passed over the fast response, low watt density heaters with ceramic cores. This type of system provides very accurate air and humidity control. A separate instrument precisely controls the heat level.
The heating systems have a long life and are very reliable, with no down time

4. Description
Flexibility for structure
The panels used in our chamber are 4” (100mm or 150mm) Thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting. So that no heavy structural members are required. Different door sizes, flooring upgrades,access ports, and other modifications are possible.
Widest test range, most customizable
