Cold Chain, Food & Beverage Processing
Cold storage and food processing facilities carry continuous, high-density refrigeration and hot-water loads that are highly sensitive to voltage instability and energy waste. Acuity has deployed tailored EMS with smart submetering, ES Modules, and APF/SVG for operators like Pacific Cold Chain, Smile Meat, and Dumex, delivering double-digit energy savings and more stable operations.
The Challenge
Refrigeration compressors and processing lines run around the clock with little tolerance for downtime, so any power-quality issue directly threatens product safety, not just the electricity bill.

Products
Voltage-Stabilizing Energy Saving Cabinet
ES Module
A plug-in energy-saving cabinet that stabilizes incoming voltage, reduces I2R and reactive power losses, and lowers heat stress on motors and equipment without any change to existing electrical infrastructure. Savings are confirmed through Measurement & Verification (M&V), typically 3-10% (7-15% in documented case studies), and it's already deployed under a CAPEX ownership model across 400+ Makro and Lotus's locations and multiple food manufacturing plants.
Pay-as-You-Save Energy Optimization Program
ES Module – ESCO Program
The same ES Module voltage-stabilization technology delivered under an Energy Service Company (ESCO) model - clients pay based on verified actual savings rather than an upfront capital purchase. Includes warranty and after-sales service bundled in, removing the need for large initial investment while still delivering M&V-confirmed energy and cost reductions.
Real-Time Harmonic Compensation
Delta Active Power Filter (APF)
Advanced active power filtering that continuously detects and compensates for harmonic currents, improving power quality and protecting critical electrical infrastructure. Eliminates harmonics up to the 50th order with dynamic reactive power compensation and sub-0.1-millisecond response, in a modular design that scales for future expansion while reducing resonance risk from capacitor banks.
Scaled Harmonic Filtering for Heavy Industrial Loads
Delta APF – High-Capacity Industrial Series
The same Delta Active Power Filter technology configured and scaled for heavy-duty facilities with large VFD banks, multiple production lines, or data-center-scale electronic loads. Delivered as part of Acuity's full-service engagement - site power quality analysis, system design, installation, commissioning, and long-term M&V - to match filtering capacity precisely to high-demand industrial environments.
Stepless Reactive Power Compensation
Delta Static Var Generator (SVG)
A next-generation replacement for conventional capacitor banks, continuously measuring reactive power demand and injecting or absorbing compensation instantly to hold Power Factor on target. Delivers stepless (not step-based) compensation across both inductive and capacitive loads in under 0.1 milliseconds, eliminating resonance risk and the overcompensation problems common with aging capacitor banks.
Intelligent Motor Speed Control for General Industry
VFD General Applications & Compact Drives Series
Delta's general-purpose VFD range, matching motor speed to actual process demand instead of running motors at full speed continuously. Delivers 20-50% energy savings on variable-torque loads like pumps, fans, blowers, compressors, and conveyors, with smooth soft-start/stop, precise speed and torque control, and reduced mechanical wear versus direct-on-line or soft-starter setups.
