Chiller Operator

The Chiller Operator at HRSI is responsible for efficiently operating and monitoring chillers and chilled-water systems to ensure optimal cooling performance. This role involves managing various parameters such as temperature, pressure, flow, current, voltage, and refrigerant conditions in line with approved operating procedures. The operator will handle equipment including chilled-water pumps, condenser-water pumps, cooling towers, and air handling units. Routine inspections, maintenance support, and rapid response to faults or alarms are crucial to maintaining continuous and reliable operation of the cooling systems. The position demands a skilled individual with hands-on experience in Carrier Chillers, possessing strong attention to detail for detecting abnormalities like unusual vibration, noise, leaks, or operational inefficiencies. Although the role does not require managing a team, it requires proactive coordination with HVAC technicians and supervisors to troubleshoot and resolve equipment issues. Safety, environmental protocols, and energy efficiency initiatives are integral aspects of the job, as well as preparing detailed operational reports as needed.
