  • Two speed control for mobile refrigeration generators
    Patent number: 8487458
    Abstract: A current sensor is installed in a generator set to measure the current being delivered from the generator set to a refrigeration unit. A control is responsive to the current transformer to reduce the speed of the drive engine to a lower speed when the current being delivered to the refrigeration unit is determined to be below a predetermined higher level. Provision is made to override the system when the sensed current is determined to be transient caused or in the event that ambient temperature is determined to be above a predetermined temperature threshold.
    Type: Grant

  • Generator set with dual mounting capability
    Patent number: 8202028
    Abstract: A generator set is provided with both a pin-on mount mechanism and a clamp-on mount mechanism for mounting the generator set to a container. Both the pin-on mount mechanism and the clamp-on mount mechanism are selectively positionable in either a deployed for use position or a stowed position. When the clamp-on mount mechanism is in the deployed for use position, the pin-on mount mechanism is positioned in a stowed position. When the pin-on mount mechanism is in the deployed for use position, the clamp-on mount mechanism is positioned in the stowed position.
