Condensation and frosting in rotary heat exchangers
Air-to-air heat exchangers used for energy recovery in ventilation units sometimes need to operate in very low outdoor temperatures. During operation the surfaces in the heat exchanger are cooled by the outdoor air and warmed by the extract air. This means that the heat exchanger has a cold side …William Lawrance
The future for air handling units under the new F-Gas regulation in the EU
As a company, we have recently focused on the topic of sustainability in a number of ways, in the context of indoor climate solutions. In previous blog posts, we have discussed topics such as the Renovation wave, the BACS decree and the recently updated F-Gas regulations - all through the lens of …William Lawrance

How to increase energy-efficiency of your air handling unit
As Google searches regarding energy-savings have somewhat skyrocketed lately, it is reasonable to think that the following search has been made more than just a few times: how to save energy + AHU?William Lawrance
The many advantages of sorption technology
Air handling units equipped with rotary heat exchangers with a sorption coating bring significant opportunity for energy and carbon emission reductions, while also improving the indoor environment. But what exactly is it that make them so advantageous? Here is a step-by-step guide to understanding …William Lawrance
Duct system pressure and SFP
The duct system pressure drop has a significant impact on the SFP. But what are the factors we need to focus on when reducing SFP? Lets take a closer look at that.William Lawrance
Getting to grips with internal leakage in air handling units
Internal leakage of air in ventilation systems is wasteful and it can also affect the indoor air quality so we need to minimise leakage to both optimise the energy consumption and ensure the best possible air quality. In this article, you will get to know different modes of internal leakages and …William Lawrance
How to optimise air handling units for healthy indoor climate – COVID-19 recommendations
With our top three advise for air handling units – regular maintenance, high flow rates, minimised return air – we can optimise operation and maintain a healthy indoor climate.William Lawrance
Commissioning air handling units is all about the work off site
The commissioning and adjustment of air handling units can be time consuming, and due to the human factor, the units are not always set-up as intended, resulting in inefficient operation. But this may soon be history, the tools to streamline the whole process are already here. And the trend is …By topics
