Humidity & VPD in Vertical Farming

Selecting an industrial dehumidifier starts with an accurate moisture load calculation. This episode walks through the seven moisture sources, a worked infiltration example and how the target dew point drives the choice of technology.

We usually judge indoor comfort by temperature alone, yet relative humidity shapes our health, productivity and the life of the building just as much. This episode uses the Sterling chart to cover the effects of low and high humidity, the ideal range and how humidity is controlled in both directions.

There are three main technologies for industrial dehumidification: desiccant rotor, condensing and pool units. This episode compares their operating principles, achievable dew points, strengths and limits, and shows how the target dew point and the ambient temperature drive the right choice.

Selecting an industrial dehumidifier is never just a single capacity figure. This episode covers eight criteria, from target relative humidity and dew point, moisture load and technology to reactivation energy, casing, automation and service, and a five-step decision process.

In winter, heated indoor air can drop below 15% relative humidity. This episode calculates the humidification load step by step from the absolute humidity difference and the volume of air entering the space, works through two examples with Türkiye climate data, and covers economisers, unit selection and the energy budget.

In an indoor pool, the heated water surface evaporates all day; this evaporation cannot be prevented, only controlled. This episode calculates evaporation with the VDI 2089 formula, works through a 32 m² villa pool example, and covers hall conditions, chloramines and corrosion, unit selection, air distribution and maintenance.

The External Analog control profile on the Neptronic SKE4, where the 0–10 V humidity signal comes from an external controller: wiring examples and high-limit settings. Narrated in Turkish.

We have signed a distribution agreement for Turkey with Canada-based Neptronic. We combine our engineering experience in industrial dehumidification with Neptronic’s steam humidification technologies, offering a single point of contact for both dehumidification and humidification. Narrated in Turkish.
