What OptiCool Technologies does
OptiCool Technologies is a privately held provider of two-phase pumped refrigerant cooling systems for data centers, founded in 2010 and headquartered in a 450,000 ft² headquarters and manufacturing facility in Webster, New York. The company has developed its proprietary Delta4T™ fourth-generation platform, which uses R-513A refrigerant as the primary heat sink in a closed-loop, phase-change architecture to absorb and transfer heat more efficiently than single-phase water-based systems. The portfolio comprises rear door heat exchangers (RDHx) in 30 kW, 60 kW and 120 kW capacities, refrigerant pumps for both chilled-water (RPW, 60–500 kW) and outdoor DX (RPC, 115–230 kW) configurations, 1.5 MW and 3.0 MW coolant distribution units (CDU-M15 and CDU-M30-1200), and active aisle containment modules. The company claims more than 7,000 active RDHx units deployed across 125+ sites, PUE as low as 1.02, 90% energy reduction versus air cooling, and a patented "Cool Door" attachment compatible with third-party racks.

- Rittal: Rittal offers data center cooling solutions including Liquid Cooling Packages (LCP) for direct-to-chip and rear-door cooling. Established player with global manufacturing that competes for the same enterprise/colocation RFPs as OptiCool.
Broad incumbents
- Schneider Electric: Schneider Electric provides comprehensive data center infrastructure including cooling, power, and management software. Broad incumbent competing with OptiCool on holistic data center solution procurement rather than on pure cooling performance.
- Trane Technologies: Trane is a large HVAC and thermal management incumbent offering chillers, CRAC/CRAH units, and water-side economizers used in data center cooling. Broad incumbent whose traditional HVAC portfolio competes at the facility-level cooling layer.
- Mitsubishi Electric (Hydronics & IT Cooling): Mitsubishi Electric offers precision cooling and chillers for data centers globally. Broad incumbent competing in the facility-cooling infrastructure layer rather than rack-level two-phase RDHx.
Emerging players
- Green Revolution Cooling (GRC): GRC specializes in single-phase immersion cooling for data centers. Adjacent emerging technology to OptiCool's two-phase cooling, often evaluated on the same hyperscale-decision shortlists.
- ZutaCore: ZutaCore provides direct-to-chip liquid cooling using two-phase technology. Early-stage emerging player with overlapping technology philosophy to OptiCool's Delta4T platform but smaller commercial scale.
