We focus on Gree air-cooled chiller performance: stable leaving-water temperature, optimized fan speeds, and smart staging to curb peak demand. Expect improved reliability, lower energy intensity, and cleaner air handling downstream.

Our Engineering-First Process

1. Assessment & Goals: We walk the site, review loads, controls, and process needs to define success—capacity, redundancy, IAQ, and efficiency targets.
2. Design & Selection: We model loads and choose Gree air-cooled chiller configurations for redundancy, acoustics, and footprint. Hydronic design covers primary/secondary pumping, expansion, air/dirt separation, and glycol if needed.
3. Proposal & Timeline: You get clear scope, schedule, and pricing, including energy-saving options and utility incentive guidance.
4. Installation & Integration: Safe demolition, rigging, piping, electrical, and controls integration with your BMS (BACnet/Modbus).
5. Commissioning: Performance testing at multiple loads; verify setpoints, alarms, and trend logs for data-driven operation.
6. Training & Handover: Operator training, O&M documentation, and maintenance calendar tailored to your facility.

Proactive Maintenance Checklist

• Seasonal cleaning of condenser coils and verification of fan operation
• Refrigerant leak detection, subcooling/superheat checks, and charge optimization
• Electrical testing: contactors, capacitors, insulation resistance, and torque checks
• Pump inspection, flow verification, and differential pressure trends
• Strainers, air separators, and expansion tank checks; coordination of water treatment
• Controls tuning: staging logic, sensor calibration, and alarm setpoints
• Performance reporting with recommendations to reduce kWh/ton

These actions extend equipment life, stabilize critical temperatures, and keep utility spend predictable. Our service agreements include priority dispatch, documented inspections, and budget-friendly planning for components nearing end of life.
