Meltdown! How to avoid a furnace disaster by using the safety features of the furnace system No one wants to hear “furnace” and “disaster” in the same sentence. Your new Deltech furnace control system was supplied with a limit controller to help you avoid one kind of catastrophe. A limit controller is a relatively inexpensive …
Dangers of manual mode furnace operation… Your high temperature lab furnace system was supplied with a programmable temperature controller which allows you to input numerous programs with various segments such as “ramp”, “soak”, and “repeat”. You can then, for example, select program #1 for product #1 and walk away, free of the need to monitor …
Following is a brief introduction to how the main components of a Deltech Furnaces resistance heating system work together. The main components are the (1) control system, including the temperature controller and control thermocouple; power control system (including SCR power controller, current transformer, and ammeter); transformer; and overtemperature protection circuit (including a limit controller, contactor, …
We’ve been asked why we control the power to molydisilicide heating elements using not only a phase angle fired SCR power controller, but also an isolation type stepdown transformer. After all, the SCR will do a good job of regulating the volts and amps required to fire the load, and the transformer is an …
Most Deltech furnaces are designed for maximum operating temperatures in the 1500-1800 deg C range and for operation in air, so molydisilicide heating elements are used because of their ability to quickly attain and sustain high temperatures and their affinity for oxidizing atmospheres. Despite their robust appearance they are a fragile, glasslike material with …
Deltech Furnaces Offers Sophisticated HMI Solutions Did you know that HMI (human machine interface) functions coupled with your Deltech furnace control system can do much more than simple data acquisition and logging? These days even the traditional chart recorder has been incorporated into programmable temperature controllers. These controllers feature the now familiar PID programming, multiple …
When looking to purchase a resistance-heated batch furnace, there are a number of factors to consider before making your final decision. Resistance-heated furnaces are electrical furnaces that use heat that is generated by conductors. These furnaces are commonly used in heat treatment, where materials need to be heated before they are melted, dried or pressure …
