Water treatment plant problems
June 6, 2022
Excessive humidity in water treatment plants causes dangerous pipe sweating and costly corrosion. Learn how the Adams County Regional Water District solved its condensation issues by implementing professional dehumidification systems. Discover why Midwest plants face unique moisture challenges and how controlling humidity levels protects infrastructure, reduces maintenance labor, and saves significant annual facility budgets.



Dirty filters and static pressure often cause commercial dehumidifiers to lose performance, leading to unwanted humidity fluctuations. Quest engineers solved this by integrating a pressure switch with a variable speed fan in the new Quest 335. This system automatically adjusts airflow to ensure consistent, precise humidity control despite clogged filters or complex ductwork.


Discover the Quest 335, the worldβs most efficient dehumidifier. Engineered with innovative multi-coil technology and a variable speed fan, this unit optimizes performance even under static pressure. Learn how our latest release removes 335 pints of water daily while slashing operational costs for cultivators and facility managers by thousands of dollars over five years.


Climate control is critical for cannabis cultivators, but dirty filters and improper ductwork often hinder commercial dehumidifier performance. Clogged filters restrict airflow, while poor duct design increases static pressure, leading to humidity fluctuations. Learn how to optimize your setup through regular maintenance and smart engineering to ensure a consistent and successful growing environment.

Powdery Mildew and Fungicides: Part 1: Background
June 12, 2017
Powdery mildew is a common fungal disease caused by the Erysiphaceae family. As an ectoparasite, this fungus grows on the surface rather than inside plant tissue. While not systemic, it spreads rapidly through spores, stunted growth, and high humidity. Learn the fundamentals of identifying, managing, and preventing this persistent plant pathogen in your garden.


Control Humidity to Best Fight Powdery Mildew
May 15, 2015
Powdery mildew thrives in high moisture environments, posing a major threat to crops. Instead of relying on pesticides, focus on environmental control. By maintaining relative humidity at 50 percent or lower, you can prevent mold at the source. Properly sizing a commercial-grade dehumidifier to match your plant transpiration rates is the most effective defense.
