inTEST Expands Eco-Friendly ThermoStream® Systems and Launches North Sciences Brand

Solving The Most Demanding Temperature Control Applications

inTEST Corporation (NYSE American: INTT), a global supplier of innovative test and process solutions for use in manufacturing and testing in key target markets which include automotive, defense/aerospace, industrial, life sciences, security, and semiconductor, today announced its thermal segment subsidiary, inTEST Thermal Solutions (iTS), engineered the next generation of ThermoStream® Systems and introduced the new North Sciences brand, born from products obtained through the acquisition of Z-Sciences in October 2021.

“Our customers rely on our expertise in precision temperature control, and we believe these quality products solve their challenging problems,” commented Nick Grant, inTEST President & CEO. “Our new North Sciences line of products offers a broad array of solutions for customers that need a variety of options, greater reliability, and superior protection for their cold storage needs.”

The all-new Eco-friendly Thermal Test Systems, the ThermoStream® ECO 560 and 660, are designed for 24/7, 365-day use in production or lab environments where small footprint, low audible noise, less heat dissipation, and lower energy usage are desirable. The ECO Series operates on an energy-efficient, 20 amp, 200-230V 50/60Hz circuit with proprietary technology delivering quiet, smooth sounding operation with swift, precise temperature transitions from -60°C to 200°C. The ECO system also eliminates the time and expense required to perform annual leak testing, because its gas charge is below the CO2 equivalent limit for greenhouse gas emissions as specified in the EU 517/2014 regulation.

The North Sciences brand was launched after products acquired from Z-Sciences were enhanced with multiple advancements including a variety of ergonomic and performance developments, along with state of the art controls technology. The brand offers a line of cold storage products, including biomedical freezers, vaccine refrigerators, blood bank and Ultra Low Temperature (ULT) freezers serving the biomedical and life sciences markets for temperatures ranging from -86°C to +10°C. These products are ideal for hospitals, research labs, and customers needing reliability, redundancy, uniformity, and sample security. North Sciences refrigeration units with innovative Twincore technology are extremely reliable, providing 100% redundancy even if a compressor fails, with industry-leading uniformity of +/-2.5°C, Energy Star certification, and EPA-rated natural refrigerants. North Sciences cold storage products range from small and portable to powerful and large-storage that cover the entire range of cold chain response for critical material storage.

iTS has been solving the most demanding temperature control applications for over 50 years. With global recognition for expertise in precise control of extreme environmental conditions, from -185°C to +500°C and rapid transitions, the breadth of iTS products and in-house engineering capabilities offers a single-partner-solution for thermal test, process cooling, and cold storage needs. The iTS family includes four product brands: Temptronic, Sigma Systems, Thermonics, and North Sciences.
