NOTE
Pressure ratio is the ratio of absolute discharge to absolute suction pressure. It can be calculated as follows:
l (DP + 101) / (SP + 101) (kPa) OR
l (DP + 14.7) / (SP + 14.7) (psi)
All TTS/TGS/TTH/TGH Series Turbocor compressors were designed for use in stationary building applications and are
suitable for some marine applications (e.g., cruise ships, floating platforms). Danfoss Turbocor compressors are
produced for civilian use and are not intended for safety critical systems. Misapplication of a Turbocor compressor
will not be covered under Danfoss LLC’s Standard Warranty Terms and Conditions.
5.5 Standards Compliance
It is the responsibility of the Original Equipment Manufacturer (OEM) to ensure that proper safety protocols are in
place and that the chiller system has been designed in a manner that is compliant with all applicable local, national,
and international codes and regulatory requirements governing the use of refrigerants, pressure, vessels, and
electrical power. OEMs must also ensure compliance with the requirements stated in the refrigerant manufacturer’s
Material Safety Data Sheet (MSDS) and that other system components are compatible with the refrigerant, giving
special attention to elastomers and seals.
