How can I add additional heating power using an HST booster heater?

JULABO heating circulators and refrigerated/heating circulators come equipped with varying heating capacities dictated by the model and line voltage. Heating power ranges between 1, 2 or 3 kW in these models.

Specifications for the 2kW and 3kW systems relate to 230V power supply. Operating on 208V will result in reduced heating power:

The unit pump and refrigeration system (cooling capacity, if applicable) will perform to the stated specifications at either voltage.

Kick it up a notch

Does your application require more heating capacity than the standard product provides? Select 230V, 3kW heating capacity JULABO models can accommodate a booster heater (HST) which increases the heating power an additional 6 kW at 230V (4.9 kW at 208V). This additional heating power adds to the 3kW heating power of the heating circulator for 9 kW total.

Models with booster heater options:

Adding the HST booster heater will either require an additional 3-phase power supply or increased amperage to the temperature control unit. The HST does not require installation at a JULABO facility making the heating power upgrade easy at the customer site.

When would you need a boost?

If your application heating capacity requirements change after installation of a temperature control unit then adding a HST becomes a simple fix.

For example, installation of a SL-12 heating circulator on an application providing heat to affect a phase change of a compressed liquid into the gas. The phase change from a liquid to a gas causes cooling which the SL-12 combats to keep the process efficient. If the process throughput increases beyond the 3kW heating capacity of the SL-12 causing the temperature to drop, then adding the HST booster heater to the SL-12 will fix the problem. Since the addition of the HST does not increase the unit footprint, this presents an excellent solution.

Another example: a FP55-SL used to control a 50L glass reactor at low temperatures. The process calls for a fast heat up time which the standard 3kW heating power from the SL cannot meet. By simply adding the HST accessory the FP55-SL can meet the faster heat up requirement.

HST booster heaters deliver a heating capacity boost to heating circulators and refrigerated/heating circulators They provide an easy way to increase heating capability in the laboratory.
