Air Blast Coolers
AIR BLAST COOLERS OVERVIEW : –
Tipo Air/Oil heat exchangers have been made to be used in the return line of the hydraulic systems. The cooler element is made from alum-alloy, which is a highly conductive material. The braise welding process of the, gives a high thermic exchange and a good pressure rating.
Mineral oils, hl, hlp, water-oil emulsion.We recommend that a bypass valve is installed in parallel to the heat exchanger, to protect it during the starting. Make sure there is no obstruction to the air flow.
FEATURES OF AIR BLAST COOLERS : –
- These are continuous flat fin and tube heat exchangers having compact and sleek design.
- Ideal for oil cooling applications where there is a scarcity of water and fir economy of operation.
- Provided with axial flow fan and motor of requisite capacity together supplied as a completely packaged unit.
- Standard sizes available from capacities ranging from 500 kcal / hr to 10,000 kcal / hr.
- Higher sizes and custom built units can be offered as per customer”s requirements.
- Designs with copper tubes / Aluminium fins and Copper tubes / Copper fins available.
- Available for working pressures up to 15 bar and working temperatures up to 150° C.
AIR BLAST COOLERS MAINTENANCE : –
Oil side cleaning: The oil side of the cooler can be cleaned by flushing with a detergent or a degreasing products compatible with aluminium. To remove the residuals silt, please use compressed air.
Air side cleaning: The air side of the cooer can be cleaned using compressed air or water. Please pay attention to the jet direction for not spoiling the vanes. If the cooler is contaminated with oil or grease, you can steam clean the cooler. Make sure the electric motor is disconnected and properly protected.
AIR BLAST COOLERS CAPACITIES : –
The cooling capacity of the heat exchangers is based on the outlet water temperature being 10�C above the ambient temperature. The rated cooling capacity will apply when there is a temperature differential between the inlet and the outlet of 10�C, e.g., in those conditions water would return to the cooling unit at 20�C above ambient. The heat extraction rate will vary according to the differential between the inlet and ambient temperatures. The greater this differential, the great the heat extraction rate at the cooler.
