We often get requests from customers for assistance building a heat solution for drying or adding heat to an existing drying system that is under-performing. This is understandable, using heat to dry is a common occurrence in our everyday lives from clothes dryers to hair dryers. In this article we explore why hot air is not always the best drying solution and talk about using fast moving air as an alternative to heat. We also give guidelines to help you decide when to use heat and when to only use air.

Regenerative versus Centrifugal Blowers Explained

8/9/2019

 
Picture
Both regenerative and centrifugal blowers are widely used in industrial processes. Superficially the two types of blowers can seem similar and it can be difficult to find good information on the differences between the two types of blowers and why one would be selected over the other.
​
First, we’ll discuss what the two types of blowers have in common. Both types move air using an impeller on a rotating shaft. The air comes in the inlet and is focused while traveling with the impeller before exhausted as linear flow at the outlet. This is where the similarities end.

The Basics of Heat Calculations

7/24/2019

 
Picture
One of the most common mistakes we see our customers making when selecting a process heater is basing their choice on temperature rating rather than power rating. Temperature can be important but is generally a dependant variable. In this article we will discuss why the power rating is such an important parameter and some of the fundamentals needed to calculate your process requirements.

In an air heater, air is blown over a resistance coil which is heated by a voltage applied across it. The temperature control of the air at the outlet of an air heater depends on the level of sophistication of the heater and any control systems with which it is integrated. Before discussing air heater control, first we will take a very high level look at system control.

Deflashing Plastic Parts with Hot Air

6/7/2019

 
Deflashing with inline air heater
Injection moulding is one of the most common industrial methods for high volume production of plastic parts. Plastic is heated until it reaches a thermoplastic state and is then injected into a mould. During this process a seam can develop on the part where different segments of the mould meet, known as the parting line. This seam of excess plastic is called flash. Flash must be removed from the part when it occurs in an area where surface finish is important or where it will cause an interference.
