Heater Circulators TU-1500

When there’s no room for error, you need a heater circulator you can trust.

With their proven consistency, precision, and reliability, our innovative circulators are what your laboratory bath’s setup has been missing.

Note: Water bath sold separately.


With an air cooled long life circulation motor and a 1500W heating element, these robust units provide precise temperature control, circulation, and heat transfer to the fluid, ensuring consistent and uniform heating of the sample.

Designed to suit the Thermoline general purpose TWB-24NE-4E laboratory water bath, our circulators were made for your lab. Our innovative circulators combine ease-of-use and high performance to help customers achieve increased productivity across many applications.

Thermoline supplies two variations of the heater circulator:

The TU-1500 fits directly into a Thermoline TWB-24NE-4E bath. The Thermoline water baths feature a bridge specially suited to the TU-1500.

The second features a sturdy universal mounting bracket (TU-1500-B) to retrofit to any exisiting uncirculated water bath. The universal clamp allows you to fix the TU-1500 to the wall of an existing water bath. The clamp features a quick-release screw.

Whether you’re in research, testing or production – our circulators have been successfully tried and tested in labs Australia-wide.

With a digital microprocessor control, you’ll enjoy greater precision, ease of use, and temperature stability (±0.2°C for temperatures from ambient +5 to 95°C). And you can safely incubate your samples – trusting they’ll remain at a constant temperature for as long as you need.

At Thermoline, we deliver on your strict requirements. As a result, we’ve set the benchmark for temperature control technology for over five decades.

And thanks to our unique precision and reliability, the Thermoline Unistat line will be an asset to your lab, for routine tasks and strict applications alike.

How do I control temperatures at or below ambient?
To achieve temperatures at or below ambient will require refrigeration of the bath. Thermoline has a wide range of refrigerated water baths to suit your needs. The TU3 is a heat-only device that controls temperatures +5°C above ambient temperature.
What is the temperature range that can be controlled by a heater circulator?
The TU-1500 is a heat-only device that controls temperatures +5°C above ambient temperature.
What is the temperature accuracy of the TU-1500 heater circulator?
The Thermoline TU-1500 heater circulators are accurate to within +/- 0.2°C.
