Technical Tips & Information
Compressed Air Tips
Here is a short list of practical tips to help eliminate water in your plant compressed air lines.At $.05 per kwh, a 100 hp compressor operating at full load for one month will consume $36,300 of electricity in one year. When a compressor is unloaded, it still consumes about 30% of the total power rating of the motor. The same 100 hp compressor operating 65% of the time fully loaded and 35% of the time unloaded will still consume $27,400 of electricity in one year.
Review the piping and valves in your compressor room to make sure that no dryers or filters are bypassed.
Make sure a piping change connecting wet air and dry air has not been done along with any open valves separating the two systems.
Make sure there are coalescing filters in front of all dryers.
Verify that all dryers are cycling, purging and re-pressurizing properly.
Dryer desiccant should be changed every 3-4 years for lubricated compressors and every 5-6 years for oil free compressors.
Air cooled aftercoolers will never operate as well as water cooled aftercoolers in high summer temperatures. A fine water spray on an air cooled unit will gain 10-15 degrees F in hot weather.
Verify that all drainers are working properly. Each piece of drying and filtration equipment must have its own drain trap. Every air receiver must also have its own drain trap to remove water which will accumulate in the tank. Remember that timer style drains can never be set to properly drain all water without wasting enormous amounts of air.
Eliminate Timer Drains-Timer drains do not operate! It is impossible to set a frequency and duration time to meet all the varying humidity conditions which exist.
Reduce Air Pressure-Lowering air pressure by 2 psig will cut operating costs 1%.
Air Leaks-A single 1/8” hole at 100 psig will waste $2,095 of air in one year.
Improper Uses of Compressed Air-Most air compressors will produce about 4 cfm of air per horsepower consumed. Most blowers will produce about 16 cfm of air per horsepower. Using a blower in place of plant compressed air will cut operating costs as much as 75%.
The Drain-All 1700 is the all time reliable and bullet proof solution for your compressed air system drainer needs.
