Inlet temperature 5 -20 to 115°F (-28 to 46°C); protection from freezing if water is present
1. If the Compressors are started at temperatures above the listed minimums and continue to run, the minimum operating temperature
is 20°F (-29°C).
2. Based on sweet gas wellhead gas. Results may vary due to gas quality and site conditions.
3. Do not apply power to the VFD if ambient temperature is below this level.
4. If power is continuously supplied to the VFD when the Compressor is off, the minimum starting temperature is -4°F (-20°C).
5. Consult factory for more details and applications guidelines.
