Placer Process Systems (PPSI) designs, fabricates, and installs prefabricated, modular, and containerized chilled water and glycol cooling-loop skids, pump packages, heat exchanger skids, utility manifolds, and piping systems for data centers across Northern California and the Western U.S.
Scope note
PPSI doesn’t provide DX refrigeration equipment or refrigerant circuits. We support the hydronic (chilled water/glycol) side of data center cooling and utility distribution
Prefabricated, Modular & Containerized Cooling Systems
Skid-mounted pumping package with piping and instrumentation
Common applications: CRAH supply/return loops, mechanical room pumping, dedicated zones for high-density halls.
Heat transfer / heat exchange skid with valves and gauges
Common applications: economizer support, cold-weather protection, liquid-cooling support loops.
Modular skid package with pumps, piping, and control system cabinet
Ideal for repeat builds, standardized halls, and minimizing field weld time.
Built for Mission-Critical Schedules and Commissioning
Placer Process (PPSI) supports hyperscale, colocation, and edge data center projects by delivering engineered systems for the chilled-water / glycol side of cooling infrastructure—pumping, distribution, heat exchange, filtration, and modular piping.
