Controlling Liquid Temperature with Refrigerated and Heated Circulators

Mark Diener, Product Manager at JULABO USA, Inc., speaks to AZoM about controlling liquid temperature in the lab with the CORIO range of refrigerated and heating circulators.

Could you please introduce JULABO and the industries that you work within?

JULABO is a worldwide leader in liquid temperature control instrumentation headquartered in Germany. Our large product portfolio encompasses instruments spanning a temperature range from -95 °C to +400 °C. The breadth of products enables us to meet specific customer application needs. Industries utilizing our products include: aerospace / defense, automotive, solar, biotechnology, pharmaceutical, petrochemical and chemical production to name a few.

JULABO was founded nearly 50 years ago – how has the company developed over this time?

JULABO was founded to advance technology developed by their forebearer’s invention of the contact thermometer to complete systems that control and maintain a specific temperature. Initially, bench top heating immersion circulators were developed. As the company grew, products including refrigeration expanded the portfolio. JULABO introduced the first digitally controlled immersion circulators in the 1970s. The drive to innovate continues to present with the PRESTO® and CORIO™ product families. JULABO now employs more than 350 members of staff with international affiliates and global distribution respresentation.

JULABO have just launched the CORIO series of refrigerated and heating circulators – what inspired the production of this range?

JULABO foresaw the need to advance technology, performance and quality in the economic heating and refrigerated / heating circulator market space. The CORIO follow the design appearance of the PRESTO series with all products crafted in Germany.

What products are available in the range, and how do their capabilities differ?

The CORIO C and CD heating immersion circulators form the core. The CORIO C provides liquid temperature control for internal applications to +100 °C. The CORIO CD expands the temperature range to +150 °C for internal and external applications with the addition of a USB port for external communication. The CORIO CD has a manual adjustment of the pump flow for internal / external circulation. A variety of plastic and metal bath tank combinations from 5 L to 39 L accommodate many applications.

The CORIO CD also pairs with four refrigeration systems to provide refrigerated / heating capabilities. The CD-200F, CD-201F, CD-300F and CD-600F encompass temperature ranges from -30...+150 °C from 200 – 600 W of cooling power at 20 °C.

What are the key applications of the CORIO series?

Applications include: sample incubation, jacketed reactor temperature control, material testing, molds, analytical instrumentation and chromatography.

Why is temperature control important in chemical industries?

Chemical industry applications require precise and reproducible temperature control to ensure proper reaction or condensing conditions. Various chemical and physical analyses depend upon temperature control for product and batch-to-batch testing.

In what ways does the CORIO range stand out from other circulators on the market?

The CORIO present an advance in liquid temperature control performance and features at a lower price point with German quality. The lightweight circulators have very bright LED displays - immediately noticeable. Increased safety with incorporation of locking power cords. Innovative quick connect clamps facilitate easy placement on bath tanks. The plastic and metal open bath combinations incorporate a proprietary rim design for quick placement of a circulator and accessories (such as test tube racks). The CORIO CD refrigerated / heating circulators provide increased cooling power with maximum bath tank accessibility.

What advancements do you expect to be made in the temperature control industry?

Mark Diener

I expect advances in communication and user interfaces to continue with a reduction in footprint for systems with refrigeration.

When will the CORIO series be available?

The CORIO is available immediately.
