Pre-Installation Mandatory Requirement

• Room temperature around machine should preferably be at 25°C with air conditioning or a well ventilated room with an exhaust
   fan.However, the surrounding temperature should not exceed 30°C.
• Stabilized Input Voltage of 230V AC, 20 Amps. Use of a Servo Controlled Stabilizer is recommended.

Calibration / Validation

i) Calibration

• Temperature sensor probe calibration with traceability to ERTL
• Temperature controller calibration with traceability to ERTL

ii) Validation
• IQ, OQ and PQ documentation and protocols shall be provided with equipment.
• Documentation prepared / developed for Osworld by Premier Validation Ltd. – Ireland, one of Europe’s
   leading validation consultants
• Performance Qualification with Temperature Mapping on site. The Performance Validation Test consists of one cycle at any
   one temperature point for an 8-hour period. Data is collected in printed format from up to six different points within the chamber.
   Temperature uniformity is considered acceptable if the deviation is less than ±1°C of set temperature.

Optional Extras / Accessories :

Walk in Cold Room • Oslog Data Storage Device and Oslog 21 CFR Part 11 Compliant Software - Both have been
   developed exclusively for Osworld by M/s Godrej & Boyce Mfg. Co. Ltd.
• Additional high-temperature safety system to cut off all heaters with audio-visual alarm
• PLC-based system: PLC with HMI 3.7” touch screen grey monitor with 21 CFR Part 11
   features (OSLOG) software.
• Door access security system
• Voltage Stabilizer for above unit
• GSM System: Alarms sent to predefined mobile numbers
• HMI: 5.7" touch screen grey in lieu of 3.7"
• Controller with printer interface to connect to EPSON Dot Matrix line printer. Date,
   time and temperature can be printed whereas print interval can be set between 1 to 99 minutes
• Data Logger: 4 point temp. Data logger with sensors placed at specific points in chamber
   with printer interface and memory
