DA 100B HD Pad Cooling
1 Product Description
DA 100B HD pad cooling is applied for cooling of large air quantities in tunnel ventilation systems. Fresh air is
directed through pads by means of negative pressure in the house. When cooling is required, the pads are kept
moist with water, which circulates from lower gutter to the top of the pad. Pad cooling can be mounted on the
wall or on the floor.
Pad cooling DA 100B HD is specially designed for cooling in hot and dry climate zones (zones with high
cooling potential). This is a result of optimization of the water amount and cooling on-time, which creates a
uniform cooling across the pads.
The system exists in 2 versions:
1. The water performance is aligned to 9 liter/min/meter pad. (System 1)
2. The water performance is aligned down to below 9 liter/min/meter pad. (System 2)
