Manufacturer Julabo
Country of manufacture Germany
Overview

Superior models for the most demanding applications
JULABO Ultra-Low Refrigerated Circulators for heating and cooling are suitable for external temperature tasks. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. ACC ‘Active Cooling Control‘ provides active cooling control across the whole temperature range. An energy saving feature with only minor loss of heat is provided by the proportional cooling capacity control in the ‘FP’ refrigeration units. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. The units are equipped with handles or castors for easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. Additionally the instruments are equipped with an improved insulation to help avoid ice-formation, and have a visual liquid level display. For working temperatures -91°C to +200 °C. Typical applications: Temperature applications to jacketed reaction vessels, autoclaves, miniplant installations, kilo labs, freezing point determination, calibration at low temperatures, petroleum testing, etc.

FPW91-SL is the most powerful JULABO ultra-low refrigerated circulator with an extended temperature range and 2-stage cascade cooling – suitable for high-volume reactors (up to 80 liters)

Models are available in the following options:

  • 90 = Unit size is 23.2 x 29.9 x 45.7 inches
  • 91 = Unit size is 33.5 x 29.9 x 45.7 inches
  • Models are available with a bath opening, suitable for external and internal application, unless designated with an N.
  • N = Models designated for external applications only offer a small filling nozzle to fill the bath liquid. No items can be immersed into the bath tank. Advantage is less cooling power loss, as there is no bath opening. (these models are designed with an N).
  • FP = Models which offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment.
  • W = Models are available in air or water-cooled. Water models are designated with a W. The advantages of water cooling are low noise level and almost zero emission of heat. But of course chilled water must be available with the customer.
  • 150 = Models are also available in an extended working temperature range of 150°C

FAQ

Do the Julabo HighTech Circulators have the capability to ramp up temperature over a set time period?

The HighTech circulators can be programmed to ramp. The best way to accomplish this is to use the free version of Julabo's EasyTEMP software. EasyTEMP provides a PC interface to create a temperature profile which is much easier than programming directly circulator. The HighTech RS232 port enables connection to a PC using a null modem cable.
