What does Short Term/Intermittent Duty Mean?

HYDAC's units can be run at full load for 5 consecutive minutes before it will reach the thermal limit of 176 degrees F - at this point, the unit must cool to ambient temperature before another full 5-minute cycle can be run. Or the units can be run at full load intermittently on a 10% motor on, 90% motor off work cycle. If the units are run below the maximum pressure the time and percentage of on time may be increased - but will not be able to run continuously without cooling.
