We are always there to assist you with upgrades and advise. You can trust our preheaters. They come in both 800°C and 900+°C versions, and provide a reliable and robust design.

Turn the heat up!

Some like it hot. We do as well. Our double shell air preheaters are well known from other industrial heat recovery applications, such as the glass industry. Ekstrom & Son are proud to offer the only such solution for carbon black producers. So ask yourself … how hot is hot enough for you? Let’s take a look at our product line.

Your next air preheater

We offer five types of air preheaters:

The single shell preheater - 900+°C

The Ekström patent pending 900+C design has an extended fire tube surface. It offers the following benefits:

  • Extended fire tube surface with lower metal temperatures – expected increased life time and safety against creep
  • Self-supporting design – reduces need for external structures
  • Two versions: Standard Height, or Compact Height (similar to our 800C models – easy to upgrade)

 

The single shell preheater – 800°C

Lower temperature difference between firetubes and process gas provide lower fouling.

In detail, this is how it works

The advantage of a double shell air preheater is lower fouling. This is due to lower temperature difference between the process gas and the tube. This leads to less cleaning and better control of your maintenance costs. The graph shows the temperature differential between CB gas and the preheated air:

Words from our clients

Air preheaters provide higher temperatures for Orion Engineered Carbons Orion Engineered Carbons is one of the world’s leading producers of Carbon Black. The engineered carbon is used for print pigments, polymers, and rubber, to mention a few applications. The air preheater is a key component in such plants. Ekström & Son provides air preheaters for some of Orion’s plants throughout the world. Continuous product development is necessary in order to help our customers innovate and be ever competitive in the market place.
