CF Series of Cryo-Compact Circulators 5.5 Liter

Category Stirred / Circulating Baths
Manufacturer Julabo
Country of manufacture Germany
Overview

The new CF series offers compact refrigerated/heating circulators. With small overall dimensions the units can even be placed on a very small surface or within a complex installation. All models offer a heating capacity of 2 kW and safety class 3 according to DIN12876-1. The maximum ambient temperature of +40°C as well as ventilation air cooling allow installing the units very closely side by side with other units or directly under a fume hood. Furthermore all the models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. Wetted parts are made of high quality stainless steel or plastic. The instruments provide reliable Microprocessor electronics with high temperature stability as well as warning and safety functions.

Features:

  • Ergonomic design and easy operation
  • Small overall dimensions for lowest space requirement
  • Splash-proof keypad
  • RS232 interface for PC connection
  • Adjustable high temperature cut-off
  • Classification 3 according to DIN12876-1
  • Pump connections for external temperature applications
  • Bath opening for temperature control of small objects in the bath
  • Front drain

High-tech model offers additional features that allow more precise control than economy models:

  • Bright VFD display and additional interactive LCD dialog display of 3 values,warning functions, high
    temperature cut-off, pump stages (resolution 0.01 °C)
  • Highly precise 'Intelligent Cascade Control', automatic and self optimizing adjustment of PID control parameters
  • TCF Temperature Control Features for individual optimization, additional settings for band limit, limits etc
  • Absolute temperature Calibration for manual compensation of a temperature difference, 3-point calibration
  • Electronically adjustable pump stages for reliable and consistent pump capacity
  • Integrated programmer for the execution of time and temperature dependent profiles, 6 temp profiles with 60 steps max., with real time clock
  • External Pt100 sensor connection for precise measurement
  • Early warning system for low liquid level for maximum safety and for high/low temperature limits
  • 3-point calibration
  • RS232/RS485 interface for PC connection
