Compatible control refrigerated circulators

These compact refrigerated circulators with insulated refrigeration baths are ideal for direct temperature control from −90 up to +200 °C. The low bath volume and high heating and cooling capacity means short heating and cooling rates, which can be increased by using the optional displacement inserts. Optional calibration inserts enable circulators to be used as calibration baths.

• Pilot ONE® is interchangeable and can be used as a remote control (with an optional data cable)
• Controller can be upgraded with enhanced functionality at any time (Exclusive and Professional E-grade® packages). The basic version features six languages (English, German, French, Spanish, Italian and Russian)
• The display resolution is 0,1 °C which can be changed to 0,01 °C (Exclusive E-grade® package); display can be customised to the users' preferences and important information e.g. set point, actual internal or process temperatures can be displayed in a larger format
• Powerful variable speed pressure/suction pump with Variable Pressure Control (VPC); speed is steplessly controlled
• User can set visual and acoustic alarms limiting the temperature range, and program the unit with its clock and calendar functions for auto start for unsupervised startup

All models have Active Cooling Control for cooling power control at the maximum working temperature and an automatic cooling power regulation which saves energy and reduces heat dissipation into the laboratory. Units feature a PT100 sensor connection, adjustable over-temperature and level protection, low liquid level warning and a drain positioned at the front for easy emptying. Natural refrigerant is available as an option, please enquire for details. All models feature the Pilot ONE® controller which offers a brilliant 14,5 cm touchscreen with graphic functions and a comfortable navigation menu in 11 languages and USB and Ethernet connections.
