The PneuTech
"Dry-Cool" Air-To-Air Cooler |
|
The PneuTech
“Dry-Cool” air-to-air cooler (US Patent No. 5,580,193) was developed
and designed for pneumatic dry bulk tank trailers
in the transport
of heat sensitive products such as sugar, plastic pellets and
resins, or the like. In
the pneumatic unloading process, compressed air is the conveying
medium. The compression
of air heats the air, which in turn heats the product. Increased
temperature is directly related to increased pressure. The higher the pressure, the
greater the temperature - temperatures up to 350 deg. Fahrenheit in
a typical operation.
How Does Hot Air Contaminate
Dry Bulk Shipments?
As the pressure
of the pneumatically conveying air rises, the product is heated
causing plastic pellets to melt and sugar to caramelize. The composition of the
pellets sticks together or breaks down into “angel hair”, rendering
them useless. Plastics, sugar and other heat sensitive products melt
and coat the tank hoppers, outlets and the discharge line, requiring
lengthy and expensive clean up procedures.
How Does the Cooler Eliminate Heat and Contamination?
Our solution: The PneuTech system
cools discharge air to ambient temperature before the air
enters the tank. The PneuTech cooler's heat exchanger is rated at 1100 ACFM and is equipped with two electric fans. It is constructed of
aluminum and the fans are powered by the tractor’s electrical
system. With the cooler installed in the air supply line between the
blower and the hopper tank, the conveying air is routed through the
heat exchanger and cooled by the fans. An automatic pressure sensor
switch controls the fans, eliminating possible operator failure to
activate the fans.
