Bharat Industries

We are recognized amongst the prominent manufacturers and suppliers of walk in chambers. The rooms of the environmental test chambers  are manufactured using prefabricated metal tongue and groove sectional panels. An assembled room has continuous steel perimeters to hold panels tightly in place. Steel straps connect locking arms with locking pins on apposite sides of panels and Cam-actuated locks ensure tight fits and accommodate frequent assembly/disassembly for relocating or enlarging the room.

Salient Features:

• 100% insulation
• Light weight for easy handling
• Alignment pins for accurate fit

Viewing Windows

• The standard multilane window has a 14" by 23" viewing area.
• Thermostatically controlled heater wire in the window casing minimizes condensation and frost formation on the window surface.
• Custom size windows are available.

The Lighting Fixtures offered by us are vapor proof and sealed. Both incandescent and fluorescent lighting fixtures are available. Incandescent lighting is recommended for high temperature units operating above +110°F and low temperature units operating below 0°F.

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. The air circulation systems use external heavy duty motors to distribute air evenly and constantly recalculate 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, wherein 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 recalculated 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.

Electric Heating System

The electric heating systems have a long life and are very reliable, with no down time. 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. These systems provide accurate air and humidity control. The systems come with a separate instrument that precisely controls the heat level.
