Exhaust ventilation plays a crucial role in concrete curing. When properly conducted, exhaust ventilation creates a vacuum in the curing area. Through a fresh air intake – opposite the exhaust system – the ventilator draws cool, dry air over the warm, damp interior surfaces in the curing chamber. The exhaust system then expels the now warm, humid air to another curing chamber or to the atmosphere, as required.
Air Exhaust Systems
Remove heat and moisture from the curing area in a timely and controlled manner.
Benefits of Exhaust Ventilation
- Remove heat and moisture from the curing area in a timely and controlled manner
- Prevent heat and moisture loss into the production area, which eliminates housekeeping and corrosion issues
- Increase ex-chamber concrete strength by 10% to 15% due to controlled drying
Reduce condensation on floors and other curing area surfaces, preventing operating issues with transport equipment and improving safety
Features
Axial Exhaust Ventilation
The Axial Exhaust Ventilation System removes excess moisture and heat in small – to medium – size curing areas at an economical price.
Removes excess moisture and heat in curing areas with a maximum length of 65ft (20m).
Output range from 2,000cfm (3,500m3/h) to 6,500cfm (11,000m3/h).
High performance axial ventilator is located in the rear wall of the curing area.
Fresh air intake is in the front of the curing area and may be achieved by raising automatic doors or through the use of louvers.
Gravity-operated louvers or motorized dampers are installed to reduce heat loss through exhaust openings.
Exposed openings may require protective high-efficiency fiberglass cowlings mounted to the building wall to prevent the encroachment of inclement weather.
Radial Exhaust Ventilation
The radial exhaust ventilation is a high-performance exhaust ventilator. It is used in large curing areas or in conjunction with the stainless or galvanized duct system, when many chambers must be exhausted independently.
For single curing areas longer than 20m (65ft) and/or when many curing rooms, located in close proximity, must be exhausted independently from one another.
Produces output over 18,800cfm (32,000m3/h).
The Radial exhaust system is mounted to the rear wall or ceiling of the curing area through the use of heavy-duty stainless steel and galvanized steel brackets either inside or outside of the production building.
A single radial ventilator provides exhausting capabilities for each curing area independently through the use of motorized dampers which are opened and closed based on exhaust requirements.
Fresh air intake is achieved by raising an automatic door or through a gravity or motorized louver.
