INTRODUCING THE M186

The Next Generation of Data Center Plate Heat Exchangers is Here

Q: What heat exchanger capacity does API Heat Transfer offer for data center cooling?

API Heat Transfer's SIGMA M186 gasketed plate heat exchanger supports up to 15MW of cooling capacity per unit for data center applications. Shell and tube configurations handle up to 30MW. Aluminum brazed units are available for applications up to 3MW. All solutions are engineered to specification using HTRI-based thermal modeling.

Q: What cooling technologies does API offer for AI and hyperscale data centers?

API Heat Transfer provides three primary cooling technologies for hyperscale and AI data center applications: gasketed plate heat exchangers for primary water-side cooling loops, shell and tube heat exchangers for high-pressure and high-temperature secondary circuits, and aluminum brazed units for supplementary cooling modules. All are compatible with direct-to-chip, rear-door, and immersion cooling architectures.

Q: How does a plate heat exchanger improve PUE in a data center?

A plate heat exchanger in a data center cooling loop enables water-side economization — transferring heat from the IT equipment cooling water to outdoor ambient air or chilled water without mechanical refrigeration. This reduces compressor run hours and can lower Power Usage Effectiveness (PUE) to 1.2 or below. API's SIGMA series gasketed plate heat exchangers are engineered for the low fouling and high thermal efficiency required in mission-critical environments.

Q: What certifications do API Heat Transfer data center cooling products carry?

API Heat Transfer data center heat exchangers are available with ASME, PED (European Pressure Equipment Directive), CRN (Canadian Registration Number), AS1210, and NR-13 certifications depending on the product series and target market. Our global manufacturing footprint in the U.S., Germany, and other locations supports local certification requirements.

Q: Can API Heat Transfer's heat exchangers support colocation and edge data center environments?

Yes. API's pre-engineered and custom heat exchanger product lines are deployed in colocation, edge, and hyperscale data center environments globally. For edge deployments with space constraints, compact brazed and plate configurations are available. For colocation facilities managing multiple tenant cooling loops, gasketed plate heat exchangers offer easy maintenance and replate capability without facility downtime.

Q: How does API Heat Transfer support data center projects from specification through commissioning?

API's application engineers work directly with data center operators, MEP engineers, and facility designers from initial thermal specification through product commissioning. This includes HTRI-based thermal modeling, review of system integration requirements, on-site commissioning support, and aftermarket service. API is a technical partner accountable for thermal performance outcomes — not just a product supplier.

The M186 is engineered for the thermal demands of modern AI, HPC, and high-density data center cooling — delivering industry-leading heat transfer performance, scalable architecture, and the reliability your uptime depends on.

The Data Center Challenge

As AI workloads and high-density racks push thermal loads higher, operators must reduce PUE, increase efficiency, and eliminate unplanned downtime across the entire cooling architecture.

Computing Density Rises.

Energy Costs Rise.

Uptime Requirements Never Change.

Thermal Density

AI workloads and GPU clusters generate 10–1,000kW per rack. Traditional air cooling can't keep pace. Liquid cooling addresses every thermal load — whichever technology fits your architecture.

10–1,000kW per rack

Energy Economics

Cooling represents 30–40% of total data center energy consumption. Every percentage point of PUE improvement translates to millions in annual savings.

30–40% of total energy

Zero Tolerance

When cooling fails, revenue stops. Each minute of downtime costs thousands. Your thermal infrastructure must deliver 99.9%+ availability without compromise — whether running enterprise workloads, AI inference, or 24/7 crypto mining operations.

99.9%+ availability
