Table 6 lists the results of the temperature prediction at the aftercooler
output, where a maximum error of 4.1% was reached.
All filters on the dryer or aftercooler
should have a pressure-differential indicator with a visual or audible alarm to inform floor personnel it is time to clean the filter.
cores, made of copper alloys in standard gas engines, are made of stainless steel in Cat's landfill generator sets to resist attack from the acids in sulfur, chlorine and fluorine.
The PowerTech 6081AFH75, also an 8.1 L diesel, has ratings up to 375 hp at 2400 rpm and is a six-cylinder, electronically controlled engine with an air-to-coolant aftercooler
and a water-cooled exhaust.
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
." One of the dual engines drives the front wheels while the other drives the rear.
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.
