HVAC & Air Washer
Electrical Control Panels
Adhunik's flagship electro-mechanical integration for Air Handling Units (AHUs), Evaporative Air Washers, Treated Fresh Air (TFA) units, and central chiller secondary pumping. Engineered with dynamic duct static pressure VFD modulation, motorized fire damper safety trips, and differential pressure filter warning telemetry.
Precision Airside Regulation & Life-Safety Interoperability
Unlike generic motor panels, Adhunik HVAC switchboards are tailored specifically around air aerodynamics, filter resistance, and damper safety.
Static Pressure VFD Modulation
Direct closed-loop integration with in-duct differential pressure (ΔP) sensors. As zone VAV dampers adjust, the fan speed modulates smoothly to maintain duct integrity and drastically cut motor kWh usage.
Motorized Fire Damper Interlock
Fail-safe cut-offs interface with 24V/230V motorized fire dampers. In an emergency, supply air fans shut down instantly to stop smoke circulation, while stairwell pressurization fans initiate automatically.
Native BMS Gateway (BACnet & Modbus)
Equipped with open protocol cards (BACnet IP, MS/TP, Modbus RTU) to deliver real-time motor frequency, running current, trip fault diagnostics, and energy data to your central Building Management System.
