Product Features : Construction Chamber interior is fabricated of stainless steel with dull finish & exterior is of stainless steel / G.I. Powder coated The inner working chamber is water & vapour tight high-grade stainless steel. All seams are arc-welded & passivated for strength & durability. Modular type prefabricated metal sectional panels which are lightweight for easy handling, fit through standard doorways, easily transported and assembled /disassembled for relocating the room. Insulation Eco friendly Poly Urethane insulation provided maximum product thermal protection & increase rigidity for reliable daily use. Full View Glass Door Full door is of toughened glass with polysulphide to view the samples without disturbing the test conditions & human safety. Air Circulation A high efficiency air circulation system is an integral part of chamber construction. This direct drive design has an extended shaft electric motor coupled to aluminum centrifugal blower wheel. This horizontal airflow across the chamber working space provides an even & accurate temperature & humidity gradient. Interior Lighting High intensity, low voltage fluorescent lights are provided. Interior light makes viewing workspace & product hassle free. Chamber Port 60mm diameter port with silicon cork is included for passing sensor probes into the chamber workspace for validation without altering the chamber. Trays & Racks Heavy duty solid stainless steel duly electro polished wiremesh type trays are provided which are easy to clean, saving time & effort & adjustable for convenience. Detachable racks with every 5” adjustable angles. Control System PLC based control system. 0.1°C Resolution for temperature & 0.1% Resolution for RH High stability & reliability; Non Volatile memory; Security lock for prevention of unauthorized tampering. Heating System High efficiency, low watt density S.S. tubular air heaters are used with ceramic core. The combination of airflow, instrument response & fast reacting heaters provides very accurate & straight line control of temperature. These heaters have a long life & are very reliable with no down time. Refrigeration System A single stage refrigeration system with a hermitically sealed reciprocating compressor. Fin & tube type bullet expanded evaporator are used. High efficiency fin & tube type bullet expanded condenser coils are used. Refrigeration design protects compressors & prolongs life keeping cool during all operating condition. Refrigeration design uses less power saving operating cost. Humidity System Humidity is generated by water evaporation in separate compartment providing a water droplet free atmosphere. This ensures excellent uniformity & stability of the chamber environment .A reservoir water tank is provided which is fitted with float valve to maintain the water level in the steam generator tank. Safety System PLC based safety controller is provided having five safety cut-off with Auto Reset facility. Lower 1 Temp cut-off (Below set Point): Cut off Refrigeration system with audio visual indication. Lower 2 Temp cut-off (Below set Point): Cut off Load supply with audio visual indication. Higher 1Temp cut-off (Above set point): Cut off Heating system with audio visual indication. Higher 2 Temp cut-off (Above set point): Cut off Load supply with audio visual indication. Boiler safety: Low water level cut-off, when water is not present in the steam generator tank. Scanner For validation purpose Temp / Humidity multipoint scanner can be provided with printer & PC interface facility. Stand by Refrigeration & Humidity System If any one of system fails to work or will be under breakdown stand by system will automatically switchover without disturbing chamber test conditions. 21 CFR PART-11 Compliance Audit Trail, E-Records & E-signatures, and Graphical analysis & Data acquisition. SMS Mobile Alert System With GSM technology we will get malfunction SMS of equipment on Mobile Phones.
