Energy Audit & Retrofit
Measured kW/TR of your existing plant and a costed retrofit plan — VFDs, chiller sequencing, tower fan control, pump right-sizing — with payback you can verify.
Utilities are 40–60% of a textile or pharma plant's electricity bill, and most plants we audit run at 1.1–1.4 kW/TR when 0.7–0.85 is achievable. An MHM energy audit measures the real numbers for a week — chiller power, flows, temperatures, tower fan hours — and turns them into a ranked list of retrofits with cost, saving and payback.
The usual winners are simple: VFDs on condenser pumps and tower fans, chilled-water reset, chiller sequencing so the right machine runs at the right load, cleaning fouled condensers, and replacing oversized pumps. We install what you approve and re-measure to prove the saving.
Everything energy audit & retrofit covers
Metered baseline
Power loggers, flow and temperature sensors on the plant for 7 days; kW/TR by load bin.
Retrofit plan
Ranked measures with capex, kWh saving, ৳ saving and simple payback.
VFD & controls
Drives on pumps and fans, chilled-water reset, sequencing and BMS trends.
Hydraulic right-sizing
Impeller trims, pump replacement and balancing to cut pumping power.
Chiller upgrades
Condenser cleaning, EXV retrofits, high-efficiency replacements where payback is under 3 years.
Measurement & verification
Post-retrofit metering and a signed M&V report for management or a lender.
