frequently asked questions
Why is humidity control necessary within an Air Handling Unit?
Humidity control is necessary because AHUs directly supply fresh outside air, meaning indoor environments are entirely exposed to seasonal moisture fluctuations. When this external air is heated or cooled by the AHU, its relative humidity is drastically altered, making it impossible to maintain a stable indoor climate without dedicated humidification or dehumidification sections.Each 1°C of temperature change automatically shifts the relative humidity by approximately 3%. For example, if you draw in fresh winter air at -5°C and 100% RH and heat it up to 21°C, the relative humidity plummets to just 16% RH. This creates an incredibly dry environment that requires dedicated humidification to restore comfortable levels for occupants or to meet the strict process requirements of the space.
How do you maintain the precise, hygienic humidity levels required within healthcare and hospital environments?
Hospitals must maintain 40–70% relative humidity to inhibit airborne viruses and satisfy NHS HTM standards. We integrate isothermal steam systems into the main air handling plant or local ductwork to deliver sterile moisture to critical areas. By calculating precise absorption distances, we select the ideal dispersion system to prevent any internal wetting. This is paired with reverse osmosis water treatment to eliminate scale, maximise hygiene, and reduce maintenance downtime. For moisture removal, our stainless steel desiccant or refrigerant dehumidifiers extract excess humidity in a completely hygienic manner.
Can your humidity systems handle fluctuating occupancy levels in corporate spaces without wasting energy?
Yes, our commercial systems use high-precision relative humidity (RH) sensors that constantly monitor the workplace environment. When a meeting room fills up and moisture levels alter, or when an office empties at the end of the day, the system automatically modulates its output in real time. This demand-controlled automation ensures a comfortable, productive environment for staff during peak hours while drastically cutting energy consumption when the building is quiet.
