Air exchangers - Import export

Heat transfer between a gaseous media and a liquid finned tube heat exchangers are often called air/water heat exchangers or gas/water heat exchangers. Heat transfer between a gas (for ex. air, steam) and a liquid (for ex. water, seawater, oil) takes place in the air-/water heat exchangers. Very often air/water heat exchangers are used as exhaust heat exchanger to gain the energy out of warm or hot exhaust fumes. Finned tube radiators can also be used as air heater, air cooler or condenser To improve the thermal output transfer from the gas to the liquid, fins made of well heat transferring materials are put on the tubes. The great increase of the thermal efficiency when applying fin tubes allows a substantial reduction in size and costs of such cooling equipment. The surface of such tubes is substantially increased and consequently less tubes are required compared with exchangers with plain tubes.

PNEUMATIC BULK TANKER TRAILER A pneumatic bulk trailer is a system applied to the trailer by vacuum or pressure for easier discharge of powder products. it is installed in the tank body without air exchange. The air pressed into the tank by means of a Cement Trailer air compressor powered by a diesel engine or electric motor allows the product to be ejected through the pipe.
