Proven Performance
High-Density Cooling, Backed by the Data
As AI and high-density computing increase thermal demands, cooling performance needs to be proven under real-world operating conditions. Cambridgeport provides published performance at entering water temperatures up to 70°F, measured glycol derates, and AHRI-certified selections established at bid.
Guardian systems are engineered around verified performance data, giving engineers and data center operators the information they need to evaluate, select, and design with confidence.
Hall to Chip
Cooling Across the Entire Thermal Chain
Modern data centers increasingly rely on both air and liquid cooling to manage higher rack densities and evolving infrastructure demands. Each Guardian unit brings these technologies together with a consistent approach to engineering, equipment selection, controls, and documentation.
From CRAHs and fan arrays at the hall level to coolant distribution units (CDUs), rear door heat exchangers at the rack, and dry cooling systems outdoors, the Guardian system is designed to support cooling across the thermal chain.
Four Proven Platforms
Guardian Series
The Guardian Series brings together four production-proven platforms engineered for mission-critical data centers — from standardized systems for repeatable deployments to fully custom equipment for complex requirements. Each is factory-packaged and run-tested for reliable performance.
Guardian FA
150-725 kW+
Large-format fan arrays engineered for high-density and hyperscale AI halls. Multi-coil V-bank configurations, 12-fan IE5 plenum walls, and vertical upflow or side discharge options are tailored to your facility, scaling from 1–3 MW per hall.
Guardian CRAH
35-200 kW
Modular horizontal fan array CRAHs designed for repeatable data center buildouts. Single-section construction, front service access, and standardized selections simplify installation and support predictable project schedules.
Guardian CRAC
35-200 kW
Standardized CRAC systems designed for reliable cooling in mission-critical environments. High-efficiency EC/IE5 fan technology, flexible airflow configurations, and double-wall construction provide precise temperature and airflow control.
Guardian Custom CRAH
150-725 kW+
Flexible, scalable CRAH systems engineered around the specific requirements of your application. Custom configurations provide the cooling capacity, airflow, construction, and serviceability required when standard designs aren't enough.
Cooling Distribution Unit (CDU)
Factory-piped and run-tested CDUs deliver precise liquid cooling and efficient heat transfer while simplifying installation and integration with high-density data center infrastructure.
Rear Door Heat Exchangers
Rack-level cooling captures heat at the source, combining chilled-water coils and EC fan-assist technology to support AI and high-density computing environments.
Dry Cooler
Efficient heat rejection without added water consumption, using Infinitum EC fan array technology to support demanding data center performance and WUE targets.

View The BrochurePerformance Data You Can Specify With Confidence
Guardian units provide the verified and certified performance data engineers need to evaluate, select, and specify mission-critical cooling equipment with confidence.
Performance to 70°F Entering Water
Published capacity data and performance curves support the warm-water conditions increasingly common in AI and high-density data centers.
Measured Glycol Performance
Measured performance data for 25–40% propylene glycol provides a reliable basis for accounting for derates under actual design conditions.
AHRI-Certified Selections
Coil selections are certified to AHRI 410 at specified schedule conditions, providing documented performance data from the start.
Validated Selection Engine
One consistent data source powers equipment selections, quotes, schedules, submittals, controls packages, and guide specifications.
Verified Performance Data
Performance is clearly identified as verified or extrapolated, providing transparency into the data behind every equipment selection.
Built in the USA
Guardian equipment is designed and manufactured in Randolph, MA, with fixed-frame systems offering lead times of approximately 10–12 weeks.
