Liquid Desiccant Dehumidifier
Efficiently reduce humidity while neutralizing airborne pathogens
For commercial growers of high-value plants that are susceptible to
one or more of the three environmentally induced diseases: botrytis,
downy mildews, or powdery mildews, humidity control is a must.
The importance is even greater when growing organically or with
pesticide-free techniques. Infection develops when fungal spores
enter plant tissue via water films, usually at night, when the leaves and
flowers cool and condensation and/or drips form.
What is needed:
• Floor space - approx. 50 sq ft.
near an exterior wall but inside
growing space
• 2’ clearance on all sides of the
machine
• Hot water - from existing system
or dedicated boiler
• Ventilation - to create air rotation
• Electricity - just enough to power
internal pumps and blowers
Versatile Options Available:
• Damper for minimal heating mode on
warm nights or exhaust to exterior
• Cool with cold water in addition to
VLHC if summer nights get too hot
• For tropical environments and indoor
applications, heat pump based HAC
provides cooling and
dehumidification only
While conventional heating systems require ventilation to drive
humid air out of the greenhouse, Agam’s VLHC internal ventilation
technology enables air circulation with closed thermal screens &
without ventilation.
The Agam Ventilated Latent Heat Converter (VLHC) liquid desiccant
system controls nighttime humidity levels, filters and neutralizes mold
spores, and saves a tremendous amount of energy: roughly 60% of
annual heating requirements compared with heating and venting
Benefits:
• Controls temperature: Heating or minimal heating modes.
Ask about cooling.
• Maintains designated humidity level
• Reduces risk of Botrytis, Mildew and more
• Saves energy - up to 60%
• Cost effective - 18 month average return on investment
• Purifies and cleans the air
How it works:
VLHC converts humid air (water & heat) from inside the
greenhouse into water vapor by blowing the air through a
matrix of desiccant-filled elements in a compact cooling tower.
In this process, water vapor is warmed up by the desiccant
and this heat is released by the unit into the greenhouse or the
exterior as warm, dry air.
