The 99 LD-3000 may be upgraded in the field to eliminate thermal induced slow-flow, provide submersible shutdown, and alarm notification to site monitoring equipment. Request information on the ISM-4080, an easy upgrade for existing or new installations. The ISM-4080 also stages turbines and controls solenoid valves for loading racks and marine applications. If there is no need for staged turbines, solenoid valve control, alarm notification or submersible shut-down, request information on the ARM-4073 to eliminate false alarms only.
