Overview of the TT/TG Compressor
NOTE
• Contact Danfoss Turbocor for lower ambient temperature operations. Refer to “Operating Envelopes,” for details of the
operating conditions. These conditions are in line with the AHRI 540 Standard.
• All compressors/components should be protected from environments that could cause corrosion to exposed metals. For
outdoor installations, a weather-proof enclosure with vents is recommended to house the compressor.
• TT/TG compressors can operate below -1°C ambient if refrigerant circuit is maintained at a minimum of -1°C Saturated
temperature.
The compressor should not be operated at an altitude higher than 3000m.
The compressor should be stored and operated within the following ambient temperature
ranges:
• Storage: -30°C to 70°C (-22°F to 158°F)
• Operation: -1°C to 52°C (30°F to 125°F).
• Mains Power Applied Non Operating Limit: -25°C (-13°F)
• Humidity: 0-95% Non Condensing
