A. KNOWLEDGE

System Operations

• Thermal & Pneumatic Infrastructure: Deep understanding of industrial chiller cycles, hot water generators (HWG), air compressors (screw/centrifugal), and complex AHU configurations.

• Regulatory Compliance: Proficiency in EPA refrigerant management (Section 608), pressure vessel safety codes, ASHRAE standards, and ISO-standard environmental frameworks.

Monitoring & Analysis

• Technical Methodologies: Expertise in psychometrics (humidity/temp control), refrigerant leak detection, and combustion analysis for boilers/HWGs.

• Instrumentation: Proficiency in using manifolds, ultrasonic leak detectors, hydrometers, and BMS (Building Management System) interfaces to ensure peak thermal performance.

Operational Analytics

• Data Interpretation: Advanced ability to analyze thermodynamic trends, pressure-enthalpy charts, and perform Root Cause Analysis (RCA) on mechanical or pneumatic failures.

B. SKILLS & ABILITIES

Technical & Maintenance

• System Proficiency: Hands-on experience with SCADA, BMS (Building Management Systems), and SAP (PM/QM) for real-time climate monitoring and asset management.

• Maintenance Excellence: Expert in planning and executing Preventive and Predictive maintenance (e.g., vibration analysis, oil sampling) for compressors, pumps, and motors.

• Calibration & Troubleshooting: Skilled in calibrating thermostats, pressure transducers, and actuators, and diagnosing complex refrigeration or pneumatic faults.

Social & Leadership

• Leadership: Proven ability to lead technical teams, manage shift handovers, and foster a "Safety-First" culture regarding high-pressure systems.

• Technical Communication: Translating complex HVAC/energy data into clear reports for management and non-technical stakeholders.

• Stakeholder Management: Coordinating with HVAC contractors, environmental auditors (EPA/local air quality), and energy utility vendors.

Resource Management

• Operational Efficiency: Optimizing COP (Coefficient of Performance) for chillers, managing air leak audits, and tracking MTBF/MTTR metrics for utility assets.

• Inventory & Cost Control: Overseeing refrigerant gases, filtration media (HEPA/ULPA), and critical spare parts for burners and compressors.

C. ATTITUDE

• Standard-Driven: Uncompromising commitment to air quality standards (cleanroom specs) and mechanical safety protocols.

• Solution-Oriented: A proactive mindset focused on identifying energy inefficiencies or mechanical wear before they become system failures.

• Adaptable & Resilient: Calm and effective during emergency system outages, refrigerant leaks, or critical temperature excursions.

• Continuous Improvement: Embracing energy-saving initiatives and Lean principles to reduce the facility’s carbon footprint.

D. OTHER JOB REQUIREMENTS

• Certification: Specialized HVAC/R certification, EPA Universal Refrigerant License, Boiler/Steam Operator License, or energy management certifications.

• Physicality: Ability to work in mechanical rooms (often loud/warm), climb ladders for rooftop unit access, and handle pressurized cylinders safely.

• Flexibility: Availability for rotating shifts, on-call emergency response for climate-critical areas, and weekend coverage

Thermal & Pneumatic Infrastructure Management

• Manage and execute preventive maintenance (PM) and diagnostic testing for high-capacity thermal assets (e.g., Centrifugal Chillers, Hot Water Generators, Screw Compressors, and AHUs).

• Act as the first responder for mechanical faults, refrigerant leaks, or pressure drops to minimize production downtime and maintain facility climate stability.

• Maintain rigorous maintenance logs and update equipment history, including runtime hours and oil/refrigerant analysis, within the CMMS or ERP.

System Reliability & Operational Integrity

• Monitor system performance parameters (approach temperatures, refrigerant pressures, dew points, and Delta T) and take corrective actions when deviations occur.

• Oversee the accuracy of environmental data, ensuring air change rates, humidity levels, and room pressures meet defined cleanroom or production standards.

• Lead Root Cause Analysis (RCA) for HVAC failures or steam/air quality excursions and implement Corrective and Preventive Actions (CAPA).

Infrastructure Projects & System Commissioning

• Plan and execute utility projects, such as the installation of Variable Frequency Drives (VFDs), upgrading BMS (Building Management System) controllers, or commissioning new HWG units.

• Coordinate with OEMs, HVAC contractors, and specialized inspectors for boiler certifications, refrigerant recovery, and balancing of air/water systems.

• Ensure all thermal projects are completed within budget, meet ASHRAE/mechanical codes, and align with energy efficiency benchmarks.

Consumables & Critical Spares Management

• Track inventory for critical spares (filters, belts, actuators, gaskets), specialized lubricants, and refrigerants to avoid operational delays.

• Ensure proper storage and handling of hazardous materials, including pressurized gas cylinders, water treatment chemicals for cooling towers, and fuel for generators.

Safety, Environmental & Regulatory Compliance

• Enforce strict adherence to OSHA, EPA (Refrigerant Management), and local pressure vessel regulations during all operational activities.

• Lead safety protocols, including Lockout/Tagout (LOTO) for high-pressure systems, chemical handling safety, and the management of Safety Data Sheets (SDS).

• Serve as the primary technical point of contact for environmental audits or energy inspections by providing emission logs, refrigerant tracking, and compliance documentation.

Technical Leadership & Coordination

• Coordinate with Production and QA/QC to prioritize cooling/heating loads and compressed air supply based on manufacturing schedules.

• Mentor and train Junior Operators on psychrometric charts, BMS interface navigation, and safe boiler start-up/shutdown procedures to ensure team competency
