Eaton Low Ambient Temperature Kit for Select Server Rack Precision Air Conditioning Systems

Protect mission-critical IT infrastructure with Eaton’s Low Ambient Temperature Kit, a purpose-built accessory for Select SmartRack In-Row Precision Cooling Units. When outdoor ambient temperatures drop below the air conditioning unit’s minimum design temperature, startups can become sluggish or fail outright, risking hot spots and equipment degradation. This kit helps your precision cooling system start reliably and operate smoothly in cold environments, ensuring uninterrupted cooling performance, faster warm-up, and reduced downtime across data centers, server rooms, and edge facilities. Engineered for seamless retrofit, it integrates with existing SR In-Row units to preserve rack space, minimize installation time, and maintain tight control over temperature and humidity in your IT spaces. Designed for rugged field use, the kit combines durable hardware with straightforward installation, so IT teams and facilities engineers can deploy it with confidence and no specialized tooling. By extending the effective operating envelope of SmartRack In-Row precision cooling, the Low Ambient Temperature Kit helps you protect critical loads during winter months, seasonal transitions, and cool ambient conditions without sacrificing efficiency or reliability.

• Compatibility and seamless integration with Select SmartRack In-Row Precision Cooling Units. This kit is designed to align with Eaton’s SR family, preserving system architecture and control logic while providing additional protection against cold-start failure. With a straightforward installation path, data centers can upgrade existing deployments without major downtime or reconfiguration. The result is a more resilient cooling solution that maintains steady IT temperatures even when outside temperatures plunge, helping you meet strict uptime requirements and service-level agreements.
• Reliable low-ambient startup and operation. The kit activates or augments the unit’s controls to facilitate normal start-up when outdoor ambient temperatures fall below the unit’s minimum design temperature. This proactive approach reduces the risk of compressor lockouts,Short cycling, and reduced cooling capacity during cold weather, so racks remain within their target temperature bands and IT equipment experiences fewer thermal excursions. By stabilizing startup behavior, the kit supports consistent humidity management and equipment performance across the data center.
• Engineering-grade components and field-compatibility. Built with rugged materials and sensor-ready interfaces, the Low Ambient Temperature Kit is designed for dependable performance in server rooms and data centers. Its compact form minimizes impact on existing ducting and airflow, while the robust mounting hardware simplifies installation in constrained spaces. The kit’s design also considers maintenance access, enabling technicians to service or replace components without disturbing critical IT equipment.
• Energy efficiency and operational resilience. By enabling reliable operation at colder ambient conditions, the kit helps avoid inefficient startup cycles and short-term thermal inefficiency that can occur when a cooling unit fights to start in low temperatures. The result is a more predictable energy profile and improved overall cooling system reliability, which translates into lower risk of hot spots and more stable IT performance even during winter storms or unseasonal cold snaps.
• Support, warranty, and serviceability. Eaton backs the Low Ambient Temperature Kit with its global support network and warranty programs, ensuring access to technical assistance, installation guidance, and spare parts. The kit is designed for straightforward field service, allowing facilities teams to maintain uptime and quickly address any issues that arise during or after installation. This support ecosystem helps data centers protect their investment in precision cooling and sustain long-term reliability.

How to install Eaton Low Ambient Temperature Kit

• Plan and verify compatibility. Confirm that your server rack cooling unit is part of the Select SmartRack In-Row Precision Cooling family and that the ambient conditions in your facility warrant a low-ambient intervention. Review Eaton installation instructions and safety guidelines before beginning the process.
• Power down and isolate the unit. For safety and to protect IT equipment, power down the affected In-Row unit per established procedures and isolate the work area to prevent interference during installation. Gather the kit components and verify all parts against the packing list.
• Mount the kit components. Use the provided mounting hardware to attach the low-ambient module or sensor assembly to the SR In-Row unit in the designated location per Eaton’s installation diagrams. Ensure secure fastening and adequate clearance for airflow and service access.
• Connect wiring and sensors. Attach the wiring harness to the unit’s control interface, connect sensors as specified, and route cables to maintain clean, unobstructed pathways. Confirm that all connections are tight and that there is no gear or cable interference with moving parts or airflow paths.
• Verify operation and calibrate. Restore power and perform a commissioning test to ensure the unit starts reliably at low ambient conditions and maintains the required temperature setpoints. Calibrate any required sensors or control parameters per the installation guide, and monitor performance to confirm stability across the anticipated cold-weather range.
