Thaw, warm, temper and transfer heat with our highly precise, easy-to-use heating circulators. Our SE and HE models allow you to store 1 program. Our HL and SL models allow you to store up to 6 programs and feature both VFD and LCD displays, including a numeric keypad. HL and SL models also include Stakei outlets for control of solenoid valves. Additionally, the SL models can combine with a booster heater for even more kilowatts of heating power.
Choose the appropriate temperature range and cooling capacity for your science with one of our HighTech refrigerated heating circulators. Our FP models offer proportional refrigeration control, which saves energy by adjusting the refrigeration percentage based on your application load. The HE models allow you to store 1 program. HL models let you store up to 6 programs and feature both VFD and LCD displays, including a numeric keypad, as well as Stakei outlets for control of solenoid valves.

When selecting a heating circulator, you’ll want to consider the size of your vessel or bath tank, the temperature range, pump pressure, flow rate, heating capacity, whether you’re doing open- or closed-loop circulation, and your ideal time-to-temperature. The JULABO team can help with your calculations, considerations, and finding a circulator to meet your needs. Get a free consultation or give us a call.
If you want to go below 20°C or ambient temperature, you’ll want a circulator with refrigeration. Refrigerated circulators allow you to set, maintain, and control temperatures in a bath or to an externally connected application. You’ll want to consider the cooling capacity and the temperature range, as well as the type of application you’re doing, your ideal-time-to-temperature, and other factors such as flow rate, pump pressure, and whether the circulator can support an automated workflow. The JULABO team can help with your calculations, considerations, and finding a circulator to meet your needs. Get a free consultation or give us a call.
Yes, all of our HighTech benchtop circulators have a built-in port for a Pt100 sensor.
All of the HighTech Circulators come with an RS232 port built in, certain models have a standard RS485 port that allows you to connect to a computer for remote control and operation.
Yes, the HighTech heating circulator and refrigerated heating circulators include an adjustable, 4-speed pressure and suction pump. The centrifugal pressure/suction pump provides a 22-26 L/min flow rate with pressures from 5.8-10.2 psi and suction from 2.9-5.8 psi. The smart-pump adjusts speeds based on changes in the fluid’s viscosity.
The circulator bath tanks are made of high-grade stainless steel and come in a variety of sizes. They also include bath covers with an ergonomic handle for easy removal and access to the bath.
The HighTech heating and refrigerated heating circulators are designed for benchtop work and can be positioned next to other applications or equipment. They can also be easily connected to external applications using insulated tubing or hosing. The HighTech models are easy to lift, move, and position in your lab, taking up little space and offering compact operations. The exact weight and dimensions of the unit vary based on the model.
Heating circulators are used for various applications, including warming reagents, warming and thawing samples, sample incubation, material testing, distillation, solvent recovery, viscometer temperature control, mass spectrometry temperature control, and much more. If you need to heat, warm, or thaw a sample, material, or application, a heating circulator can help.
Refrigerated heating circulators are used to cool, chill, and remove heat from samples, materials, applications, and other laboratory equipment. Circulators with refrigeration are used for sample incubation; material testing; molds and extrusions; analytical instrumentation and component testing; and external temperature control for rotary evaporators, jacketed reactors, fermenters, viscometers, rheometers, photometers, refractormeters, chromatography columns, and more.
In most refrigeration systems, the compressor kicks on, and the system is either 100% on or 100% off, like the refrigerator in your kitchen. Proportional refrigeration control adjusts the amount of cooling power based on the application load, reducing stress on the compressor, extending the life of the system, and lowering energy consumption.
JULABO heating and refrigerated circulators allow you to transfer heat using various liquids and fluids, including water for some applications up to 90°C. Thermal fluids such as silicone and flourinet/gladen are compatible with our circulators and baths.
