Pre-Installation Mandatory Requirement
  1. Continuous supply of Distilled water or DM water with a tap for boiler input of ½” BSP at 3 feet height
  2. Room temperature around machine preferably at 25°C with air conditioning or a well-ventilated room with an exhaust fan. The surrounding temperature should not exceed 30°C
  3. Stabilized input voltage of 230V AC, 20 Amps. Use of Servo Controlled Stability Chamber is recommended
  4. Water drain line with ½” nozzle to be provided at floor level.
Safety Features
  • High temperature safety cut-off
  • Low water level boiler cut-off
  • Electrical overload cutoff relay for compressor
  • Time delay for compressor switch ON
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
