Ultra-Low Refrigerated - Heating Circulators - TopTech Series

Category Stirred/Circulating Baths Accessories
Manufacturer Julabo
Overview

JULABO Ultra-Low Refrigerated & Heating Circulators Series are suitable for working temperatures from -91°C to +200°C. 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 heat-up and cool-down 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. The units are equipped with handles or castors for an easy transportation. With drain port 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 applications to jacketed reaction vessels, autoclaves, miniplant installations, kilo labs, freezing point determination, calibration at low temperatures, petroleum testing, etc.

FAQ

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

The TopTech 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 TopTech RS232 port enables connection to a PC using a null modem cable.
