DA 150B Pad Cooling
1 Product Description
DA 150B 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.
