Energy Saving and Environmental Improvement
Treating oil-contaminated condensate with a high-quality auto drain trap for saving energy
As to discharge of condensate generated fr om an air compressor, problems of high air loss and high oil content have been
identified, which leads to energy loss and environmental problems,
preventive measures are needed.
Condensate discharge method
Valve
- Manual Valve
- Compressed air, produced by high-cost power, is discharged into the air in order to discharge condensate.
Float Trap
-
The float trap requires frequent disassembly and cleaning due to the small nozzle diameter (0.7∅).
(which explains the need for opening of a bypass valve) - Impurities in the float cause air loss because the nozzle can’ t be closed.
- Viscosity of oil reduces buoyancy of the float for an oil-injected compressor, and this requires frequent replacement cost.
Timer Trap
- Frequent failure occurs because of compression pressure directly applied to a solenoid valve.
- A large amount of air is lost because condensate is discharged via time setting regardless of the amount.
- Excessive noise is caused during discharge
Level Sensor Trap
Own product
- Tr aps detected by the level sensor to drain condensate
- Level sensor-type drains from high-level sensor to low-level sensor without loss of air
- Large drain diameter with little blockage when discharged
- After installation, all operation are automated and easy to manage without any other settings
- If the condensate discharge is not carried out properly, Switch to automatic restore function and automatically open every 3 minutes for 5 seconds to solve the problem
Condensate Occurrence Point
Division | Compressor | Receiver tank | Dryer | Filter |
|---|---|---|---|---|
Winter | 78% | 11% | 11% | – |
Spring / Autumn | 61% | 13% | 21% | 4% |
Summer | 61% | 11% | 25% | 3% |
Damage caused by condensate
Incomplete discharge of condensate generated from an air compressor can cause shortened life and failure of
an air compressor, air dryer, receiver tank, production facilities, and so forth.
Air Loss Amount
by using Drain Trap
Drain Trap Type | Calculating the amount of Air Loss |
|---|---|
Timer Trap | 562,000won / 1point Party x 9EA = 5,058,000won / year |
Manual Valve Open | 1,686,000won / 1point Party x 9EA = 15,174,000won / year |
Drain Master | Zero |
What’s the sure way to discharge condensate?
regarding an oil injection compressor, condensate causes frequent clogging of a drain trap that lowers efficiency,
affects air quality, results in high energy loss due to air loss, and contaminates water because of high oil content.
Installation of a semi-permanent drain trap and oil-water separator, which discharge condensate only
without energy loss, can maximize efficiency in terms of operation and maintenance.
