Refrigeration System

• The air cooled refrigeration system has been designed to maintain the set temperature in elevated ambient temperature environments
• CFC-free refrigerants.
• Extra large condenser with two aerodynamic axial fans provides increased air circulation and heat expulsion.
• Down flow evaporator for efficient refrigerant flow, oil return, and longer compressor life.
  
• Washable condenser filter keeps fins dust-free, maintaining optimal cooling efficiency. No tools are required for removal.

Control System

• Key Pad, multi-functional display, microprocessor controller.
• Password protected security system for power, temperature & alarm settings.
• Independent operating temperatures and high/low limit alarm. Factory setting for rapid setup and system start. Temperature adjustments in increments of 1°C.
  

Electrical System

• Automatic voltage compensation to flatten voltage fluctuations.
• Online incoming line voltage monitoring with digital read-out.
  
• Built-in surge suppressor minimizes effect of incoming voltage spikes.
• Solid state relay. No moving parts in the compressor drive circuit. No voltage spikes on start-up, protecting the microprocessor controller.
  
• Circuit breaker. Protects compressor and power supply circuits.
• Built in Automatic Delay Restart (ADR). Ensures on line quality after power failure, decreasing power load, protecting the compressor.
  

Alarm System

• Intelligent Self-Diagnosis (I.S.D) system controller monitors system parameters and displays alarm status in real time.
• Audible & visual alarms alert you to the following:
  
• Temperature Changes
• Power failure
  
• Low back up battery voltage
• Door ajar
  
• Battery is automatically charged. The backup battery provides full system function during power failure.
• Remote alarm contacts for advanced protection
  
• Automatic temperature fluctuation recognition and logging.
• Key pad alarm test function to test the alarm system without opening the freezer door.
  

Monitoring System

• Voltage compensation indicator. Automatically monitors and adjusts incoming voltage, compensating for voltage spikes, ensuring compressor operation is within specifications.
• Low battery indicator. Flashing light indicates when battery needs replacement.
  
• Surge suppressor indicator monitors, the circuit breaker.
• Compressor life protection monitors and automatically adjusts freezer conditions, extending compressor life.
  
• Computer interface
