Schulz SRS 60 - Dimensioning

85
In order to correctly apply the factor in Table 7.1, it is necessary to check the compressed air flow generated by the air compressor and
apply the formula below:
Minimum Dryer Flow = (Generated Compressed Air Flow) x (FTA) x (FTAC) x (FP)
TABLE 7.1 - FLOW CORRECTION
Room temperature 10 30 38 40 42 44 46
Corrective factors (FTA) 0,95 1 1 1,06 1,12 1,17 1,22
Compressed Air Temperature 25 35 38 40 44 48 52
Corrective Factor (FTAC) 0,9 0,95 1 1,07 1,22 1,36 1,52

Corrective Factor (FP) 1,07 1,03 1 0,95 0,93 0,91 0,89
SRS - Compressed Air Dryers have been manufactured in compliance with the ISO-7183 Standard; class B, operating in ideal conditions.
The performance of the dryer must be corrected whenever there are any divergences occur, such as:
- Room Temperature
If room temperature exceeds 38°C, it is necessary to correct the loss of efficiency as stated in the Table 7.1 factors. For dimensioning pur-
poses, it is important to check the installation site of the SRS - Compressed Air Dryer and measure the temperature on hot days, based on
the region.
- Compressed Air Inlet Temperature
In hot room temperature, the inlet temperature of the compressed air to the air dryer tends to be very high. To correctly dimension the equi-
pment, it is necessary to measure and employ corrective factors as stated in Table 7.1.
A common method for estimating the compressed air inlet temperature to the dryer is to add a value from 10 to 15°C to the measured room
temperature. This estimation is only valid for SCHULZ Scroll Compressors. It is possible to exceed these values depending on the installa-
tion. If the estimated compressed air inlet temperature exceeds 38°C, check and apply corrective factors.
It is necessary to measure the temperature at the dryer air inlet for Alternating Piston Compresses. The mechanic can install a “termopar”
in the inlet air tube immediately before the dryer.
- Compressed Air Pressure
The SRS - Compressed Air Dryer has been dimensioned for pipeline operation at a minimum of 7 bar pressure, if the minimum pipeline
pressure is different, check the factors stated on Table 7.1.
