The Kelvion Draft-Free Air Cooler (KVB Series) is a fanless (gravity-type) evaporator designed for applications where minimal air movement, high humidity, and quiet operation are essential. Instead of using forced-air fans, it relies on natural convection to circulate cooled air, creating a stable storage environment without drafts or fan noise. This makes it ideal for ripening rooms, cheese aging, meat processing, and flower storage.
Unlike conventional evaporators that use fans, the Kelvion KVB operates through natural air circulation:
Warm air naturally rises toward the evaporator.
The refrigerant inside the coil absorbs heat.
As the air cools, it becomes denser and gently sinks.
This creates a continuous, natural airflow without fans.
The room maintains a uniform temperature and high humidity with minimal product dehydration.
This gentle cooling process helps preserve sensitive products by reducing moisture loss and surface drying.
