    The Thermal Loop & Industry 4.0

    Industry 4.0 technology enables the capture and processing of data in real time, both where its generated and where it is needed, to implement effective improvements to industrial processes. Capturing data, though, is not enough. The advantage Watlow® brings to an Industry 4.0 project are its thermal experts, who understand both the important role thermal loop systems play in key applications and industry 4.0 implementations.

Full Product Information

EZ-ZONE® Integrated Multi-Function Controller

Watlow’s family of EZ-ZONE® integrated multi-function controllers combine temperature, process and machine control, over- and under-temperature limit protection, high amperage power switching, safety disconnects and field communications into a single package. Offering a variety of modular form factors and display types in place of several components, the EZ-ZONE is convenient and reliable. Watlow multi-function controllers are ideal for use in simple to complex applications, such as DNA processing. When data logging, data storage and communications are critical, multi-function controllers provide primary and secondary temperature control with universal inputs, including thermistors. EZ-ZONE temperature controllers can be configured with an agency-approved microprocessor temperature controller and limit in one package. Simple applications requiring one loop of control and one limit loop can be achieved in as small as a 1/16 DIN package size.

fluent in-line heater

FLUENT® In-Line Heaters

Watlow’s new FLUENT® in-line heater is a small, lightweight, high-performance heater that can replace both a traditional immersion type heater or a heater wrapped around a tube as part of a thermal system. FLUENT features an all stainless steel construction for a clean, non-contaminating heat source.

SERIES EHG® SL10 Process Controller and Safety Limit

The SERIES EHG® SL 10 process controller and safety limit is a powerful system that integrates a heater with an adjustable set point temperature controller, high/low temperature alert, a power switching device and a high temperature safety limit. The EHG SL 10 in-line or sub-panel mount temperature controller / limit is an ideal combination for any device requiring thermal management. Its small adjustable or fixed set point, precise temperature control with a built-in agency approved controller / safety limit enables versatility across many applications.

Full Product Information

Polyimide Heaters

Solvent-resistant polyimide is a thin, lightweight organic polymer film that provides excellent tensile strength, tear resistance and dimensional stability. Watlow’s polyimide heater is used for DNA analysis equipment and clinical diagnostic instrumentation that require low outgassing in a vacuum or resistance to radiation, fungus and chemicals.

Full Product Information

Temperature Sensor Technologies

Achieving temperature sensor accuracy, repeatability and stability are key factors that determine how well an application performs. For some applications, such as measuring blood or body fluid temperatures, response to small changes in temperature is critical to patient health. Watlow thermal engineers combine deep knowledge of various applications with material science, thermodynamics, electrical properties and connectivity to develop sensors for specific medical applications. The result is a sensor that consistently yields the best performance in medical device applications. Typically integrated with a Watlow heater for clinical diagnostic applications, Watlow sensor assemblies deliver fast, accurate and repeatable temperature measurement.

Watlow silicone rubber heater for Clinical Equipment usage

Silicone Rubber Heaters

Rugged, yet thin, lightweight and flexible, Watlow silicone rubber heaters put heat where it is needed to improve heat transfer, speed warm-ups and decrease wattage requirements. Fiberglass-reinforced silicone rubber provides dimensional stability without sacrificing flexibility. A minimal amount of material separates the element from the part to enable rapid and efficient heat transfer.
