DRAIN MASTER
- Air leakage is so little that economic effect is excellent, and withdrawal of early investment expense is fast.
- Outlet diameter is large (inside diameter 12) that there is no block phenomenon, and it is safety because there is restoration ability when converts to emergency mode.
- All operations are automated that control is easy.
- Model is various from small to high-capacity according to capacity of using compressor.
Reason and solution of condensate occurrence in compressor system
Why happens condensate?
- Compressor inhales air from atmosphere and saturated vapor that is flowed when compress becomes water in compression process.
- In the case of condensate, was polluted extremely by dust in air, pollutant, oil, etc., in the case of oil free compressor, it is acidified that causticity is strong.
Condensate! What is problem?
- Corrodes and contaminates compressed air piping, air tank, air filter etc., and furthermore, it gives serious effect to high equipment and product in production field.
- In the case of winter, condensate is exposed to danger of burst by frozen in piping and machine equipment.
Necessity of auto drain trap
- To prevent damage of condensate, there are used existing trap of ball float method and timer method, but these have fatal weakness that are often blocked or flow out much expensive compressed air.
- DRAIN MASTER has equipped authoritative and convenient nature for condensate discharge that can give epoch - making change to existing condensate discharge system.
DRAIN MASTER Operation Principle
Figure 1: Condensate that flowed in through lead-in line 1 is gathered in housing 2, and upper space of diaphragm through pilot control line 3 becomes dynamic pressure. If diaphragm seat upper space becomes dynamic pressure, diaphragm is closed by spring pressure and it prevents escapes of compressed air.
Figure 2: 2 If condensate water level rises in housing, it is sensed in the high level sensor 6 and solenoid controlled valve is begun action and close pie lot supply line, compressed air in diaphragm upper space becomes atmospheric pressure state by venting.
Then, diaphragm of valve 7 lifting by pressure of inflow line, condensate is discharged to outside through drain line 8.
Advantage that is DRAIN MASTER
Electrostatic capacity sensor
Any condensate from compression process can be sensed correctly and discharged.
There are little loss of compressed air
Uses of two sensors (high level, low level) protects energy loss by air loss discharging condensate selectively.
Automatic discharge function
In case of condensate is not discharged while 2 minutes by scale etc., it makes recognition to user through alarm signal and it is converted to automatic restoration function and it activates electric motion ball valve by 5 seconds every 3 minutes. It is returned by normally mode if discharge is achieved normally.
Durability (Hard-Anodizing)
Housing coated rigid coating applying for aircraft, semiconductor equipment etc. of industrial equipment required durability is excellent nature of rust proof durability and abrasion etc. so that life of housing is semi-permanent.
Various model, beautiful design
Extended user's selection by subdividing into three models according to quantity of condensate, and housing is processed by anodizing method and die casting mold that has beautiful design.
Convenience of install and maintenance
- Put lead-in line more than 2 lines so that power connection is easy, and piping is convenient.
- Housing internal pollutant cleaning is simple.
- The built-in strainer can prevent the breakage of valve by the sludge and phenomenon to be blocked.
