Refrigerated and heating circulators are ideal for temperature application to external systems with simultaneous operation in the bath tank. Units provide high heating/cooling capacities to ensure rapid heating and cooling times, with Active Cooling Control to +200 °C (not on ED or F12 models). FP models offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment. Convenient cleaning of dust by removable front vent grid. Some models have a handle or castors to allow easy transport. All models include a drain port on the front to allow the bath fluid to be easily drained off. Typical applications: Temperature control of external, closed systems, such as spectrophotometers, refractometers, viscometers. For simultaneous temperature control of small objects in the circulator bath.

  • LED temperature display for actual and set point values
  • Keypad for set point input
  • Adjustable over-temperature/dry-running protection
  • High temperature cut-off/ low liquid level protection (float)
  • Timer function
  • RS232 interface
  • Three point calibration
  • Early warning system for low liquid level and high/low temperature
  • Wide temperature range and electronically adjustable pump capacity

Models have a bright VFD comfort display for simultaneous indication of internal/external set point and actual values, and PID cascade temperature control for highest internal and external temperature stability.
Electronically adjustable pump capacity including illuminated pump stage display
Connection for external PT100 sensor for measurement and control
Integrated programmer with 10 program steps

HE models:
Have optional electronic module with analogue connections for temperature recorder and set point programmer.
Particularly powerful pressure and suction pump to 1,1 bar, electronically adjustable
ICC (Intelligent Cascade Control), self-optimising
TCF (Temperature Control Features) for band limit, limit setting, co-speed factor, control dynamics

HL models:
Features as HE, and in addition have LCD dialogue-display, backlit with interactive menu and connections for optional solenoid valves or HST Booster heater with an additional heating capacity of 4 kW.
RS232/RS485 interface for comprehensive communication and networking possibilities
Integrated programmer for six 60-step programs

All units with an RS232 interface can use the free EasyTemp software for control via a PC, the software can be downloaded free of charge. Please contact Avantor for details.
