AA Series exhaust hoods, fan guard, and venturi frames can be provided in galvanized steel or stainless steel materials. If requested, these hood components can be powder coated to meet typical plant/site color code conventions, or they can be Heresite coated for corrosion protection. The fasteners for assembly can be galvanized steel or stainless steel. […]

Soil Vapor Extraction: Carbon Bed Precoolers
Soils that have been contaminated by chemical spills are often remediated using an air sparge and soil vapor extraction (SVE) process to remove volatile organic compounds (VOCs). After harmful chemical vapors are extracted from the ground using a vacuum blower, they need to be removed from the air stream, usually by an activated carbon bed […]

Blower Aftercooler with Ducted Fan Air Flow
Optionally, AA Series heat exchangers can be fitted with duct flanges on the intake side, exhaust side, or both. These heat exchangers typically serve as blower aftercoolers, where ambient air is used to dissipate heat from hot air from the discharge of a rotory lobe or centrifugal blower. Typically these units are installed outdoors, so […]
Portable Air Cooled Heat Exchanger for Truck Unloading
The pictured AA Series heat exchangers use two 12V motors to be powered by a truck or other portable battery. The connections are cam and groove fittings to quickly attach and detach hoses for hot intake and cool discharge air. These units have locking casters on one end and a cart handle on the other for ease […]

High Capacity Air Cooled Blower Aftercooler
A single aftercooler for a high capacity centrifugal blower can be used to bring the discharge air temperature to near ambient in order to protect downstream piping, protect conveyed product, or to reduce the required chiller capacity if lower outlet temperatures are required. High pressure losses downstream of a centrifugal blower will cause reduced flow […]
