Danfoss TMM 089 User Manual

Temperature and Viscosity
Temperature
High temperature limits apply at the hottest point in the transmission loop, which is normally the motor
case drain. Ensure the system generally runs at or below the rated temperature. The maximum
intermittent temperature is based on material properties: Never exceed it.
Cold oil will generally not affect the durability of the transmission components, but it may affect the
ability of oil to flow and transmit power: therefore ensure temperatures remain 16 °C [30 °F] above the
pour point of the hydraulic fluid. Minimum temperature relates to the physical properties of component
materials.
Size heat exchangers to keep the fluid within these limits. Danfoss recommends testing to verify that
these temperature limits are not exceeded.
Viscosity
For maximum efficiency and bearing life, ensure the fluid viscosity remains in the recommended range.
Minimum viscosity should be encountered only during brief occasions of maximum ambient
temperature and severe duty cycle operation. Maximum viscosity should be encountered only at cold
start.
