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.Per-Åke Ottemark
Things to consider when choosing an AHU for small premises
When choosing an air handling unit (AHU) for smaller premises, such as retail areas in an otherwise residential buildings, you may not have an assigned technical room, and the premises may be on the ground level.

Inhaling these allergens trigger a reaction of the immune system, which can lead to asthma and rhinitis.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
