Chemical Service Technician Data Centers

Chemical Service Technician for Data Centers—Reno, Nevada

Oversee the chemical cleaning, passivation, and flushing of primary cooling loops during the construction phase of large-scale data centers. Perform on-site technical lead role, coordinating with mechanical contractors to ensure water chemistry meets stringent, time-sensitive specifications and managing the logistics and documentation for each project in a Google document workflow (Google Workspace).

In-Field and In-Plant Passivation Operations:

• In-plant passivation of stainless steel
• System Flushing & Cleaning:
  Lead the chemical cleaning and "pre-operational" flushing of closed-loop chilled water systems.
• Water Analysis:
  Perform on-site water chemistry testing (e.g., pH, conductivity, iron levels, azole concentrations) to verify system readiness.
• Mechanical Contractor Assistance:
  Work side-by-side with mechanical contractors to manage roadblocks, pump setups, dose chemistry, and filtration.
• Equipment Maintenance:
  Ensure all chemical feed equipment and monitoring controllers are properly installed and calibrated.
• Service Existing Datacenters:
  Perform service by checking residuals, swapping out filtration, and dosing any necessary chemicals. Write a service report at the end of each service.

Project Management & Logistics:

• Inventory & Ordering:
  Forecast chemical volumes required for system volumes and place timely orders to avoid site delays.
• Join weekly project meetings
• Logistics Oversight:
  Track shipments and coordinate the delivery of bulk chemicals or IBC totes to active construction sites.
• Documentation:
  Maintain precise "Daily Field Reports" and final documentation for the client (Owner's Rep) and/or mechanical contractors.
• Schedule Management:
  Align chemical treatment phases with the mechanical construction schedule to ensure on-time commissioning and product delivery.
