If you’re an industrial business owner, you know that every element of your industrial ventilation systems needs to be as efficient and cost-effective as possible. One way to ensure maximum efficiency is by choosing the right fan for your air movement requirements. But which type works best in a given situation—axial or centrifugal? Today, we will compare these …

Industrial Axial or Centrifugal Fans: Which is the Best Option? Read More »

Industrial fans and ventilation systems are an important part of any industrial facility. Both axial and centrifugal fans can be mechanically driven in two ways: direct drive and belt drive. In this article, we’ll discuss the differences between these two options and some advantages of each. Industrial Fans and Ventilation Solutions: Why Your Facility Needs …

An investment in a new or upgraded industrial ventilation system can have a significant benefit on the performance and comfort of people, product and processes in your facility.  But what guarantee do you have that the ventilation system will actually perform as it was designed?  In this week’s blog, I’ll and talk about the difference …

Before the introduction of variable frequency drives (VFDs) in the early 1980’s, the only option for controlling fan motor speed was to build a motor with two different speeds.  The problem with two speed motors is that they were expense and had very long manufacturing lead times.  VFDs with current technology can cost effectively control …

To create a successful environment where workers are healthy, comfortable and productive, an industrial ventilation system must begin with the goal of making the inside temperature the same as the outside temperature.  With the right number of air changes, the ventilation system will remove the solar and internal heat loads that create dangerous working conditions.  But what can be done if after removing these heat loads, the inside temperature is still very hot?  The solution is to add spot cooling equipment that can provide additional heat relief.  In this article, I will discuss three spot cooling solutions that we recommend to our customers.   

The ability to read a fan curve has become a dying skill set.  With the introduction of fan selection software, fan selection has become as easy as entering the required inputs and then letting the software interpret which fan is best suited for the operating conditions.  But, what will someone do if years after the …

When replacing general ventilation fans, customers often ask if the replacement fans can provide more airflow without increasing the fan size.  Before providing the customer with an answer, we will need to assess their existing fans and evaluate the options for adding more airflow.  In this article, I’ll discuss the options for increasing airflow utilizing …

One of the ventilation system design principles for an industrial facility is to determine the amount of air flow needed to remove internal heat load.  When the solar heat load is the only heat load, the activities inside or the purpose of the facility will determine what is an appropriate air change rate.  But what …

When designing an industrial ventilation system, an important design criterion is determining whether the facility requires a positive or negative pressure environment to protect people, products, and processes. In this week’s blog I’ll discuss the benefits of both, the factors that should be considered, and how the ventilation equipment should be sized to achieve the …
