01 / Our capabilities

Test. Analyze. Solve.
Solutions for real equipment.

01VIBRATION / Hz / RPM

Mechanical testing & vibration

Mechanical testing
Evaluate pumps, fans, motors, compressors, and connected piping under operating conditions.
Vibration analysis
Assess vibration levels and frequency content to investigate imbalance, misalignment, looseness, and bearing-related symptoms.
Frequency & resonance investigation
Examine speed-related vibration and suspected resonance to define corrective actions or further dynamic testing.
02kW / TR / ΔT

Thermal & total capacity

Total capacity analysis
Determine available chiller output, coincident cooling demand, and capacity margin.
Ambient & process-load analysis
Evaluate temperature-dependent performance and heat loads from compressors, blowers, pumps, and heat exchangers.
Chiller sizing & upgrades
Define required capacity and recommend supplemental cooling, retrofit, or replacement.
03kW / PF / VFD

Power, drives & controls

Power analysis
Assess electrical demand, phase balance, power factor, and equipment energy performance.
Drive & electrical-frequency analysis
Evaluate supply frequency, harmonics, and VFD operation in relation to equipment behavior.
Controls & functional testing
Verify sensors, equipment staging, operating sequences, and response to approved test conditions.
04FLOW / ΔP / RELIABILITY

System diagnostics & solutions

Hydronic & coolant performance
Evaluate flow, pressure losses, temperatures, and heat transfer to identify system restrictions.
Failure investigation
Connect operating history and field evidence to likely failure mechanisms and targeted verification.
Optimization & technical reporting
Deliver calculations, findings, practical modifications, and a prioritized corrective scope.

02 / Testing & analysis

Beyond the reading.
Find the reason.

Testing and simulation help explain equipment behavior. Analysis turns those findings into practical solutions.

Connected-system behavior

See how the
system responds.

A change in load, control command, or operating condition can affect several components at once. A useful investigation follows those interactions.

  • Load changes & transient response
  • Control behavior & equipment interaction
  • Predicted response vs. measured evidence
Q̇ = ṁ cp ΔTQmargin = Qavailable − QloadPF = P / Sf = RPM / 60

Separate a symptom from its underlying mechanical cause.

Measure

Vibration amplitude and frequency content, shaft speed, measurement direction, and operating load.

Interpret

Compare response at bearings, supports, and connected components. Evaluate patterns consistent with imbalance, misalignment, looseness, or bearing distress against the operating evidence.

Deliver

Measurement-location record, frequency findings, supported fault hypotheses, and a corrective verification plan.

Power-quality testing.

A test plan with a purpose

The right measurement.
The right conclusion.

Define the operating question, measurement locations, equipment state, and acceptance criteria before testing begins.

Vibration analysis & rotating equipment.
Mechanical response
Vibration sensors and speed references selected for the required frequency range and measurement direction.
Thermal & hydraulic duty
Temperature, pressure, and flow measurements reconciled with fluid properties and equipment data.
Electrical behavior
Power and drive measurements correlated with loading, controls, and mechanical response.
Evidence quality
Documented instruments, test conditions, assumptions, and limitations keep conclusions traceable.

03 / From findings to action
