Ultra-low temperature refrigerated circulators for heating and cooling. The units are suitable for external temperature applications with simultaneous operation in the bath tank. The units provide particularly high heating and cooling capacities for rapid heating and cooling times even for large volume, external systems. FP models offer proportional cooling control to ensure energy saving performance and to reduce heat generation to the environment. Models with the designation W are water cooled. All models have handles and castors which allow easy transportation and drain ports for conveniently draining the bath fluid. The units offer an improved insulation to prevent ice formation and have a filling level display. Typical applications: Temperature control of jacketed reaction vessels, autoclaves, mini plant installations, kilo labs, freezing point determination, calibration at low temperatures and petroleum testing.

• Actual and up to three set temperatures can be viewed
• Electronically adjustable pump capacity including illuminated pump stage display
• Connection for external PT100 sensor for measurement and control
• Integrated programmer with 10 program steps
• RS232 interface

ME models:
Feature 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. Early warning systems with audible signal for low liquid level, and for high/low temperature limits. It is possible to calibrate three temperatures simultaneously.

HL, SL models:
Same features as ME, and in addition have backlit LCD, with interactive menu and connections for optional solenoid valves or HST Booster heater with an additional heating capacity of 6 kW. An electronic module with analogue connections for temperature recorder and set point programmer available as an optional accessory.

ICC intelligent, self-optimising cascade temperature control
TCF (Temperature Control Features) for band limit, limit setting, co-speed factor and control dynamics
Particularly powerful pressure and suction pump to 1,1 bar, electronically adjustable
RS232/RS485 interface for comprehensive communication and networking possibilities
Integrated programmer for six 60-step programs

Max. flow rate/max. pressure:

ME: 11 to 16 L/min, 450 mbar (with electronically adjustable pump capacity)
HL, SL: 22 to 26 L/min, 700 mbar pressure, 400 mbar suction (with electronically adjustable pump capacity)
