A unifying concept of the thermal loop

or Watlow, the underlying concept behind everything they do is that of the thermal loop. Every product offered, and every project worked on, is ultimately about the creation and control of a thermal loop in some application. There are four foundational components of the thermal loop; sensing, control, heating and managing the integrity of the data, which helps optimize that process. Eurotherm (acquired by Watlow in 2022) have a solid reputation for their deep domain knowledge and expert solutions in process automation and especially in managing data integrity, particularly in highly regulated industries and recently previewed Edge Process Management (EPM) Data (https://

What is the thermal loop, and why do customers care?
A thermal loop is a system designed to precisely control the temperature of a part, fluid, or environment. Precise control of temperature requires more than simply heating, it also requires accommodating variation in the system such as fluctuations in voltage or environmental conditions and adjusting these to maintain consistent system performance.
Another critical choice in the design of any industrial thermal system, is the selection of a power controller. This depends on a host of factors that go well beyond simple power requirements. The Watlow family of power controllers is significantly extended when combined with Eurotherm offerings, offering a comprehensive spectrum of functionality.
Why do we talk in terms of “thermal loops” at all? Why not just talk about heaters, sensors, control, and data management?
Understanding the thinking that goes into choosing the right components, and putting

them together, is a far greater challenge. This is where Watlow’s deep expertise comes in. Some issues that arise in a thermal loop are “systems problems” rather than a problem with any one component. Helping customers achieve their goals often starts with an analysis of the system. Watlow brings more than 100 years of expertise and best practice to bear on a customer’s application. Once that value is demonstrated, the relationship as a trusted partner can grow.
