Why You Should Use PID

by Logan Hedrick

The ideal way to control an electric heater is to use a PID controller in conjunction with a contactor and Solid-state device. Unfortunately, though, most companies choose the cheapest option which is on/off or bang-bang control with a contactor. As we dive deeper into why this option is not the best, first we must explore what PID, Solid state devices, and Contactors are.

The Power of Thermal Heat in Environmental Cleanup

The utilization of thermal heat in environmental cleanup represents a strategic and versatile approach to tackling pollution. Whether by accelerating reactions, enhancing physical processes, optimizing chemical reactions, or aiding in pollutant breakdown, thermal heat emerges as a cornerstone in the quest for effective and sustainable remediation practices. As industries continue to invest in innovative solutions, the role of thermal heat in shaping the future of environmental cleanup cannot be overstated.

Surface Heaters - an Overview

by Jerry Sain

​As the name suggests, a surface heater is a device that raises the temperature of a surface. Now in the world of heaters, surface heaters aren't really very sexy - they often consist of little more than a few pieces of mica and some wire. But throw in a thermocouple or a diode and some creative geometry, and they can get down-right interesting.

Estimating the Resistance Wire Temperature for an Open Coil Heating Element

by Dexter Diepholz

​For a typical convection air heating application, the air temperature and the volumetric air flow entering the heating element, and the power produced by the element are known or can be specified. The desired air temperature out of the heating element is achieved by commonly adjusting the power and/or the airflow.

Grounding Your Heater

by Kevin Green

​Grounding is often treated as an afterthought, but not all grounds or ground connections are the same. Too often we just assume that any ground connection will be a ‘good’ one. Grounding a device generally serves two purposes. The first is to provide a safe path for current flow in the event of a short circuit. The second is to provide a true “zero voltage” reference for the circuit.

Watts Killing Your Heater?

by Patrick Laws

Once process equipment is designed and placed into service, the importance of each individual component is frequently forgotten. Unfortunately, heaters often find themselves in this situation until there is a failure. Since heaters usually play an integral role within the application, any failure can rapidly expand to a major issue or shutdown. The good news…many of these disasters can be avoided by increasing the mean time between failures!

Electric Heating Systems; Branch Circuit Protection

by Shawn Gibbs

When designing an electric heating system for industrial processes, many factors must be addressed. These factors routinely include required power, location, ducting, air source, and controls, but circuit protection is often overlooked. Proper circuit protection is of utmost importance not only for safety but also to avoid costly downtime and repairs to the system. Electrical branch type and size of protection are important considerations when adding circuit protection to a heating system. Depending on the type of control employed, the speed of operation can also be a factor.

Duct Heaters Overview

by Jerry Sain

As the name implies, duct heaters are generally designed to be installed into ducting. They are usually installed through the side wall to cause the air in the duct to be heated as it flows around and through the open-coil elements. Duct heaters made by Tutco-Farnam are not for HVAC use. They are for industrial type applications and are not built to the standards required for the typical residential HVAC. For HVAC applications go to www.tutco.com.

Zoned Versus Distributed Wattage - Definition and Application

by Dennis White

In the heating industry, we are often asked what is the difference between a distributed wattage heater and a zoned heater. These various construction techniques can be applied to many different types of conduction heaters such as cartridges, ceramic and mica strips, and band heaters. Almost any heater that uses a wound coil can use one of these construction methods of controlling watt density. Before beginning, some definitions should be discussed.
