Data Centers
Data centers run dense, harmonic-heavy electronic loads around the clock, making power quality and cooling efficiency critical to uptime. Acuity's APF and SVG systems eliminate harmonics and correct power factor in real time, protecting UPS systems, transformers, and IT infrastructure from voltage-related failures.
The Challenge
Server racks, UPS systems, and cooling infrastructure generate heavy harmonic distortion, and even brief power-quality events can cascade into costly downtime for always-on IT operations.

Products
Compact Wall-Mounted Energy Recovery Ventilator
Airvera Flow+
A compact ERV for homes and light-commercial spaces that continuously supplies filtered fresh outdoor air while recovering up to 97% of indoor thermal energy through a built-in ceramic core. Single wall-penetration installation with magnetic connection, app/remote/voice control, PM2.5 filtration, and whisper-quiet operation under 32.7 dB(A) - delivering 60 CMH airflow at just 6-7.8 W.
Ceiling-Mounted Energy Recovery Ventilator for Commercial Buildings
Airvera Ceiling Pro
A ceiling-concealed ERV built for offices, hospitals, schools, and other commercial buildings needing continuous fresh air without excessive HVAC load. Delivers up to ~70% enthalpy heat recovery across a 200-1,300 m3/h airflow range, with optional F7/H10/H13/carbon filtration, CO2-based demand control, night free-cooling, and RS-485 integration with BMS/EMS - cutting ventilation-related energy loss by up to 24%.
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.
Scalable Reactive Power Compensation for Smaller Loads
Delta SVG – Compact Modular Series
A modular configuration of Delta's SVG technology sized for smaller installations or facilities planning phased expansion - welding shops, small cranes/hoist operations, and single-line production. Delivers the same stepless, sub-0.1ms compensation performance as the full-scale SVG, engineered, installed, and verified by Acuity as part of a complete power-quality solution.
