Walk In Cold Chamber/ Cooling Cabinet Construction • PUF Insulation with density of 40 Kgs/mt.3 with both side SS 304 sheet of 0.6 mm thickness duly tested & certified. • Tongue and Groove type Interlocks for Panels used in construction of Walk-In and High Capacity Stand Alone Chambers. • Heavy Duty insulated Floor Panel with anti skid carpet for secured movement. Sample Storage • Racks - secured with strong joints internally to the chamber walls, made of heavy duty SS304 frame. • Trays - Heavy Duty Perforated type, with special CNC punched perforations specially designed to maximize circulation aiding the constant uniformity in the chamber. The trays are secured with additional underside support rails to prevent flexing and warping after prolonged usage. Door • Heavy Duty Insulated Door with Full View Double layered Toughened Glass for viewing sample with good visibility. Control System • Ergonomically designed Control Panel wiring with systematic sequential ferrule printing for input and output to all components like PLC, Contactors, Isolators, MCBs SSRs. easy maintenance made possible with the aide of easy to understand wiring diagrams. • Advanced PLC program with built-in processor based Auto-Tuning to achieve and maintain constant Uniformity of set condition. • 4.3" HMI provided with adequate local data storage and a Colour TFT/LCD Display with accurate representation of operating condition in contrasting colours for easy readability from a considerable distance. • Built-In redundancy and safe guards to protect sensitive components from voltage surges. • Advanced high accuracy transmitter sensors for temperature and humidity with output of 4 to 20 mA. Dedicated voltage and surge protection for sensors. Temperature Control • Efficient, simplistic and a functionally proven design of refrigeration system using Emerson- Copeland compressors with built-in redundancy with PLC based auto-change over during intermittent power outages or component failure. • ‘U’ shaped SS Air Heater Banks controlled by PLC to achieve & chamber internal air temperature • Unique Chiller system provided with Walk-In Stability Chambers involve circulation of Chilled water through the evaporator coil providing longer sustenance of conditions during intermittent & accidental power outages.
