However, the size of the compressors largely dictates the size and weight of the cabinet that houses the compressors, 2nd stage aftercooler
, and 1st stage condenser.
The compressor and aftercooler
equipment are contained in a semi-portable cabinet that is relatively heavy but still portable.
The compressors are complete with starter, aftercooler
and sound attenuating enclosure.
The closed-loop system uses a two-pass cross flow recuperator, a two-pass cross flow aftercooler
and a Luehr gas cooler prior to filtration.
It is powered by two specially-tuned versions of the production JCB444 powerplant, developing up to 750A bhp each and featuring four cylinders and five litres of displacement, accompanied by two stage turbochargers, intercooler and aftercooler
The air leaving the high-pressure compressor is cooled in an aftercooler
and then introduced into the humidifier column, where it comes into counter-current contact with hot water.
High temperature refrigerated dryers include an aftercooler
and are primarily used with piston compressors, as the air must be precooled prior to entering the dryer for it to be effective.
A patented cooling technique eliminates the need for an aftercooler
-- which saves space on the cannon -- and incurs a temperature rise of just 125[degrees]F.
Overall, they tell us, the carryover from these compressors, after the aftercooler
, is 3ppm or less.
The natural gas engine-driven compressor has heat available from the compressor, the engine jacket water, the aftercooler
, and the exhaust heat stack.
Further, the condenser and aftercooler
share a separate closed-loop water cooling system.
The only way to remove this water before it enters the blast cleaning equipment is by using an aftercooler
between the compressor and the equipment.
