How to deal with low temperature startup in winter?
Method 1: Removal of moisture in the air pipe
Air equipment may freeze if a lot of moisture remains in the piping.
The silencer in the exhaust port of the valve is a point prone to freezing due to adiabatic expansion* during exhaust.
It is difficult to remove moisture with an air filter, so we recommend installing an air dryer!
(*The temperature of the gas drops when the compressed air is released to the atmosphere. If the air contains a lot of moisture, it will freeze around the silencer when it is exhausted.)
Method 2: Heat/insulate the valve itself
(1) Heat the compressed air itself with a heater
(2) Heat the valve with a ribbon-shaped electric heating wire heater
(3) Irradiate the bulb with an incandescent bulb
(4) Cover the valve with insulation
Method 3: Exchange to DM2® D Series
Compared to the conventional cross flow type (CF) and parallel flow type (PF) operating environment temperature of 4 to 50°C, the operating environment temperature of the DM2 ® D series is -10 °C to 50 °C . More stable operation can be expected by switching to the DM2®D series .
Method 4: * Modification to O- ring specifications
cross flow, parallel flow, tandem flow
For large valves (IN-OUT pipe diameter 1-1/4 to 1-1/2 inch )
The main piston seal (U-cup) is for the DM2 ® D series .
O- rings ( usable from -10 °C) can be used.
By replacing and remodeling the piston seal, you can expect more stable operation.
*Caution: O-ring conversion is a unique initiative of Los Asia.
With the cooperation of our customers, we have performed operation tests on actual production lines in the winter and obtained good results.
It does not guarantee the operating environment temperature of -10°C.
