NOTE
Pressure ratio is the ratio of absolute discharge to absolute suction pressure. It can be calculated as follows:
• (DP + 101) / (SP + 101) (kPa) OR
• (DP + 14.7) / (SP + 14.7) (psi)
• TT and TG Series Turbocor Compressors were designed for use in stationary
building applications.
• An OEMs use of Turbocor Compressors in applications other than stationary
building applications (e.g. Marine Applications) is considered a non-standard
application and is not eligible for warranty under DTCs standard warranty Terms
and Conditions.
It is the responsibility of the 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 local 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.
