LabRepCo LabRepCo PRECISION Series 23 cu. ft. Laboratory Refrigerator | Hinged Glass Door

Refrigeration System

• Compressor: Hermetic, variable speed (VSC). Rated speed range: 1300-4000 rpm
• Refrigerant: EPA SNAP compliant, R600a
• Condenser: Anti-fouling tube and grid design, ultra-quiet multi-speed fan
• Evaporator: Fin and tube design, high efficiency fan
• Defrost: Cycle optimized, zero energy

Controller, Configuration, Alarms and Monitoring

• Controller technology: Proportional Integral Derivative (PID) microprocessor with LCD display
• Battery Backup: 24V high-capacity battery, controller, all alarms active, temperature monitoring DAQ and event logging active on battery backup
• Display technology: Non-applicable
• Digital Communication: RS-485 (MODBUS)
• Data Transfer: USB port for data transfer and software updates
• Chart Recorder: Non-applicable
• Adjustable Temperature Range: 1°C to 10°C
• External alarm connection: State switching remote alarm contacts
• Alarms: Alarm logging (last 100 entries) with Visual and audible indicators: Power failure, Temperature sensor failure, Battery voltage monitor and replacement, High / Low temperature, Door ajar.
• Controller probe: Bottle with glass bead thermal media
• Disclaimers: Performance data acquired at 22°C ambient, 4°C nominal set point in an empty cabinet with drawers using validation ballast probes, during stabilized steady state operation and a DAQ sampling rate of one measurement every 10 seconds
  • Uniformity is defined as the maximum variance in temperature across all probes at any point in time over the testing period
  • Stability is defined as the maximum variance in temperature experienced by any single probe over the testing period
  • Data per Energy Star test results or equivalent testing and calculation. Heat rejection based on daily averages, not continuous operation. Performance exceeds Energy Star requirements.
