SJJ Series Rack-mount Precision Air Conditioner

SJJ Series Rack-mount Precision Air Conditioner

Compact Embedded Cooling Solution for Single Cabinets & Dense IT Racks

1. Product Overview

      Our SJJ series rack-mount precision air conditioner is developed for integrated cabinets, micro-module facilities and medium & high heat-density data centers. Designed for embedded rack installation, it sits close to internal heat sources to absorb high sensible heat generated by IT hardware and eliminate cabinet hotspots at source. 

      It shortens air circulation paths and raises return air temperature to boost heat exchange efficiency with remarkable energy-saving performance, cutting overall facility PUE and supporting low-carbon green data center construction. With cooling capacity ranging from 3.5kW to 12.5kW, it fits standard server racks and high-power blade server cabinets, and can integrate with UPS units and centralized monitoring platforms to deliver refined rack-level management for both power protection and temperature control.

2. Core Product Strengths

2.1 Close-proximity In-cabinet Cooling Removes Hotspots

      Mounted inside the rack to deliver cooling right beside heat-generating servers, it avoids cold air loss from long-distance airflow of room-level or row-level CRAH systems. It solves uneven temperature distribution inside cabinets and prevents server downtime & UPS battery aging caused by local overheating, perfectly suited for racks loaded with blade servers.

2.2 Short Air Loop Boosts Energy Efficiency

      Compact supply/return air path brings higher return air temperature; full sensible cooling design eliminates unnecessary dehumidification consumption to cut rack power draw and optimize overall PUE, helping global sites meet energy audit compliance for green data centers.

2.3 Standard Rack Installation Saves Floor Space

      Fitting directly into standard server racks without extra floor occupation, it adapts to space-limited layouts including single-row racks, micro-modules and all-in-one cabinet suites, supporting both new construction and legacy facility expansion projects.

2.4 Tiered Cooling Ratings for Accurate Sizing

      Multiple capacity options from 3.5kW to 12.5kW with single-phase power input allow precise selection based on per-rack power density, preventing wasted over-capacity or insufficient cooling output.

2.5 Native Integration with Central O&M System

      It connects to data center environment monitoring platforms and syncs UPS operation data, enabling remote tracking of rack temperature, AC running status and fault alerts for granular rack-side operation management.

      Every cabinet equipped with the SJJ series rack-mount precision air conditioner can be monitored independently on your unified data center dashboard.

5. Tangible Benefits for Global Clients

     1.Spot temperature control eliminates rack hotspots and lowers overheating failure risks for servers and UPS systems to secure business continuity

     2.High-efficiency cooling reduces PUE and annual power spending to satisfy green data center energy assessment requirements

     3.Embedded layout saves public floor area and improves overall space utilization of compact server rooms

     4.Independent cooling per rack allows incremental capacity expansion without revamping central chilled water or air duct systems

     5.Rack-level independent monitoring pinpoints faults rapidly and cuts complicated troubleshooting workload of centralized cooling infrastructure

     For distributed edge computing sites and modular colocation zones, the standardized SJJ series rack-mount precision air conditioner simplifies cross-site cooling deployment and unifies operation standards.

6. FAQ

Q1: Can this rack-mount AC work with mainstream UPS brands and third-party monitoring platforms?

A: Yes, reserved standard communication interfaces support integration with most global UPS products and data center O&M systems for centralized alarm and remote status viewing when you deploy the SJJ series rack-mount precision air conditioner.

Q2: Which model should I select for blade server racks?

A: Our technical team will calculate per-rack heat load and recommend proper capacity based on your server configuration and power draw.

Q3: Is single-phase power input suitable for global branch server rooms?

A: Single-phase input fits common power specifications for overseas edge sites, branch offices and compact modular computer rooms.

Q4: Can I add more units gradually when expanding racks later?

A: Absolutely, each unit runs independently, you can deploy extra rack ACs alongside new racks without modifying existing cooling infrastructure.
