Monitor critical cooling pumps and fans from the electrical cabinet. SAM4 turns current and voltage into fault evidence and a recommended maintenance action.
For suitable three-phase motor-driven equipment.
A control loop can hold pressure while a pump works harder. Other machines can carry the load. For the facilities team, the question is which machine needs attention before the next maintenance window.
SAM4 adds current-and-voltage evidence for motor electrical faults and load-related changes. Cabinet measurements can also extend coverage to suitable pumps and fans that are difficult to instrument. Use both where the extra evidence changes a maintenance decision.
Redundancy helps keep cooling available after a fault. SAM4 helps identify deterioration in operating pumps and fans so you can investigate and prepare the repair. Plan work around available cooling capacity, and assess standby units during suitable test runs.
SAM4 measures current and voltage at the motor control cabinet. Electrical faults and changes in shaft load can leave distinct patterns in that signal.
For pumps and fans that are difficult to reach, cabinet measurements avoid the need to mount a condition sensor on the machine. Samotics assesses the patterns and recommends a maintenance response.
Existing BMS and vibration systems remain part of the assessment. Start with the assets where an electrical diagnostic would add a useful maintenance decision.

Primary and secondary pumps circulating chilled water between the plant and the equipment it serves. Start with regularly running, critical pump sets.

Review monitoring fit
Cooling-tower, dry-cooler and larger air-handler fans with conventional three-phase motors. Review the motor and fan train together.
Review monitoring fitGlycol and heat-recovery pumps where the circuit is important to site operation. Similar machinery does not always mean equal criticality.
Review monitoring fitPublished examples from food manufacturing and wood production. Each connects an electrical finding to an inspection and maintenance response.
SAM4 tracked a change at the pump’s rotational frequency. The customer found a missing coupling bolt and scheduled a repair at the next planned stop.
Read the cooling-pump detection ↗Electrical trends prompted inspections, component repairs and impeller cleaning. After maintenance, SAM4 confirmed that the monitored signals returned to normal.
Read the fan detections ↗Fit follows the machine, its duty and the maintenance decision. Use this shortlist to define the monitoring scope.
Motor electrical faults, misalignment and hydraulic changes such as cavitation. Bearing evidence depends on location and load path.
Identify the pump to inspect and prepare the repair around the site’s cooling and redundancy requirements.
Electrical asymmetry, load-coupled mechanical faults and changes in the pump’s hydraulic operating behaviour.
Investigate a deteriorating pump while the team can still choose a suitable maintenance window.
Motor electrical faults, mechanical unbalance and changes linked to belts, couplings or bearings where the load path carries the signal.
Locate the fan train that needs inspection and prepare work around access and available cooling capacity.
Motor and mechanically coupled faults, changing load and hydraulic behaviour in suitable centrifugal pump sets.
Bring essential auxiliary pumps into the same condition-review process as the central plant.
Include the motor nameplate, drive model, normal speed range and operating hours. We review the signal path and agree which faults to monitor.
Review the motor, compressor and drive together. A chiller’s critical role does not establish diagnostic coverage for every compressor design.
Coolant distribution units and EC fan arrays need an OEM-specific review of signal access, motor type and the diagnostics already installed.
Low-runtime standby pumps may not provide enough operating data. UPS systems, batteries and switchgear are outside this page’s SAM4 scope.
Agree the asset scope, fit installation into the site’s electrical work plan, and route findings to the people responsible for maintenance.
Review the installation approach ↗SAM4 adds electrical evidence alongside those systems. It can help with motor-circuit faults, load-related changes and suitable assets that are difficult to instrument. If vibration checks are periodic, continuous cabinet monitoring can also add visibility between rounds. On assets with continuous vibration, assess the specific additional fault coverage. Vibration remains valuable for accessible bearings and structural faults.
When a unit is out of service, the plant may have less spare capacity until it is repaired. Condition evidence can help identify deterioration, prepare parts and choose an inspection or repair window. That supports maintenance planning around the redundancy you have. SAM4 does not certify spare capacity or replace failover testing.
Yes, on suitable configurations. Drive harmonics, speed changes and load variation affect signal quality. We review the drive setup, operating range and target fault modes before defining coverage.
Condition monitoring needs operating data. Duty rotation or scheduled test runs can provide it when the run duration and load are sufficient. SAM4 does not establish the condition of a stopped pump or replace a failover test.
No. Start with conventional three-phase motor-driven pumps and fans. Integrated EC fans, small permanent-magnet drives and CDU assemblies require a separate assessment of motor compatibility and signal access.
Agree an initial asset scope and target faults. Compare SAM4 findings with your BMS, drive diagnostics, vibration data and inspection results. Review useful coverage, false alerts and maintenance decisions changed before extending the scope.
This scope provides monitoring and maintenance recommendations. The BMS, equipment controls, protective systems and site operating procedures retain their roles.
Bring the pump and fan list, motor details and current monitoring setup. Use the review to agree the priority assets, target faults and added coverage worth evaluating.
