Process Heat

Decarbonization efforts worldwide, led both by industry leaders and legislation, have increased efforts to shift fossil fuel use to renewables. One way many industrial organizations can embrace this – and already have – is by shifting process heater systems from fuel-burning to electric.

Heat Trace and Electric Process Heaters are used in many critical processes in all plants.  It is extremely important that you and your team know how to properly test, install and maintain your electric heaters. Lack of attention in regard to these fundamentals will lead to costly heater shutdown and will cause an interruption in your process.

The use of INPUT/OUTPUT software filters can provide enhanced performance of controllers to process systems conditions. The use of Input filters are to reduce the erratic fluctuations of the analog input signal due to either electrical noise conditions or rapid fluctuations of the analog input signal. It accomplishes this by slowing down the response of the analog input to a change.

In Watlow catalogs, brochures and web pages there is a category of controllers listed as Limits and Alarms. It is not always clear to everyone when to use these controllers or which type of controller to use. This document is an attempt to clear up some of these issues.

Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of ch...

Customers who wish to control three phase heaters require power controllers. How do you decide which method of control to select? Two-leg versus three-leg control and zero cross versus phase-angle control need to be considered. The following will help you decide when each method is appropriate.

In today's world, there is an ever increasing awareness and focus on safety. A system designer needs to understand all aspects of design that can affect the safety and reliability of the system they are implementing.

There are very few elegant solutions for mid-to-large scale heavy industrial applications that require compact, high-temperature heating sources capable of delivering precise heat energy to a targeted location.
