Humidification for laboratories

Too many laboratories are still not Legionella-safe. Legionella bacteria are found in at least 10% - 15% of drinking water systems. Should these bacteria find their way into the lungs of the laboratory staff they can cause serious illness, and sometimes even death.


The right expertise in humidity for a Legionella-safe laboratory



The incorrect use of humidification systems can result in Legionella contamination. Our experts have the knowledge and experience to ensure that your system remains Legionella free, whilst complying with the strictest hygiene and safety regulations.

Save at least 33% on your energy use

Adiabatic humidification uses significantly less energy than electric steam humidification. Adiabatic humidification uses cold water. The water is misted into the air and absorbed using the latent energy in the air itself in the form of heat. The only energy costs are those used to dispel the water vapour, and sometimes additional heating costs to offset the cooling effect. Steam humidification however requires a lot of energy as the water has to be converted to steam before being released into the air. In this way adiabatic humidification saves at least a third on your energy bills.

Wood is sensitive to moisture levels. It shrinks, warps, and cracks. A Cumulus installation creates a stable humidity. That is essential for our production process and our KOMO certification.
