What We Build

Central Plant Control Panel Types

Chiller Plant Sequencing Panels

Central plant control panels that sequence multiple chillers, chilled water pumps, condenser water pumps, and cooling towers for optimal efficiency. We build panels with lead/lag sequencing, load-based staging, chilled water reset, and demand limiting — with full BMS integration via BACnet or Modbus.

Boiler Plant Control Panels

Boiler plant sequencing and control panels for hot water and steam systems. We build panels that stage multiple boilers, manage hot water pumps, control mixing valves, and implement outdoor air reset strategies. Compatible with all major boiler brands and BMS platforms.

Cooling Tower Control Panels

Cooling tower fan control panels with VFD-based fan speed control, basin temperature control, free cooling enabling, and condenser water temperature reset. Includes chemical treatment interlock and BMS integration for central plant optimization.

Heat Exchanger & HX Bypass Panels

Control panels for plate-and-frame heat exchangers, waterside economizers, and heat recovery systems. We build panels that manage heat exchanger bypass valves, differential pressure control, and free cooling logic as part of a larger central plant control strategy.

Chilled Water Pump VFD Panels

Variable frequency drive (VFD) panels for primary, secondary, and tertiary chilled water pumps. Includes differential pressure control, pump lead/lag sequencing, flow monitoring, and BMS integration. We supply and mount VFDs from Allen-Bradley, Siemens, ABB, and Danfoss.

Condenser Water System Panels

Condenser water pump and cooling tower fan control panels for water-cooled chiller plants. Includes condenser water temperature reset, tower fan staging, basin heater control, and freeze protection logic.

Instrumentation Services

Central Plant Instrumentation Takeoffs

We offer instrumentation takeoffs and sensor bidding for chiller plant and boiler plant projects. Our team reviews your mechanical drawings and BMS point lists to bid and supply all sensors, transmitters, flow meters, and current transformers required for your central plant.

We source instruments from Siemens, Johnson Controls, Honeywell, Setra, Dwyer, and Onicon, and coordinate delivery to align with your panel fabrication and project schedule. This allows mechanical contractors, BMS integrators, and OEM manufacturers to consolidate panel and instrumentation procurement with a single qualified vendor.
