Watlow
Watlow offers the most complete product line in the industry. With more than a quarter of a million designs on file, Watlow has the heater, sensor, or controller to meet your needs. see more
While some companies manufacture just heaters or just controllers, Watlow provides single source performance accountability by creating all thermal system components. From electric heaters of all types and sizes, power controllers that maximize heater performance, temperature controllers for more precise heat regulation, to sensors that provide the controllers with accurate temperature signals, you can count on Watlow to design thermal systems in which the components work together better.
Watlow's controllers are built with Control Confidence® to withstand hostile environments such as heat, electrical noise, static discharge, humidity, and vibration.
