SLDS Series Chilled Water Precision CRAH Unit

SLDS Series Chilled Water Precision CRAH Unit

High-precision Constant Temperature & Humidity Solution for Campus-scale Data Centers

1. Product Overview

      Our SLDS series chilled water precision CRAH unit is engineered for medium-to-large campus-level server rooms and data facilities, which relies on chilled water supplied by centralized chiller plants for heat exchange cooling. 

      Integrated with electric heating modules and electrode humidifiers, it delivers highly accurate linked temperature and humidity regulation. The unit comes fully assembled with heat exchanger, heater bank, fan array, intelligent controller, humidifier, water flow control valve, G4-grade air filter and differential pressure switch. 

      The full set of hydraulic, airflow and control components guarantees stable round-the-clock operation and outstanding energy efficiency. With cooling capacity ranging from 28.5kW to 185.3kW and support for parallel multi-unit deployment, it fits centralized cooling projects including large IDC parks, telecom core hubs and precision laboratories. It can connect seamlessly with UPS systems and site monitoring platforms to unify power protection, cooling and environment management.

2. Core Technical Advantages

2.1 Central Chilled Water Architecture for Campus-scale Cooling

      It works with on-site central chiller plants, removing the need for individual outdoor condensing units for each CRAH. This design cuts capital cost for scattered piping and outdoor unit installation, making it highly cost-effective for multi-building data campuses and large colocation IDCs while lowering long-term O&M workload.

2.2 Integrated Precision Temperature & Humidity Regulation

      Built-in electric heating compensation and electrode humidifiers offset ambient changes caused by seasonal climate shift and variable IT load, maintaining strict indoor climate benchmarks for core server rooms and metrology-grade laboratories.

2.3 Pre-integrated Components with Proactive Fault Alert

      The water flow valve dynamically adjusts chilled water flux; the G4 air filter pairs with a differential pressure switch to trigger clogging reminders for timely replacement. The central controller coordinates all sub-systems steadily for 24/7 continuous operation.

2.4 Full Sensible Cooling to Lower Data Center PUE

      Total cooling capacity equals sensible cooling capacity across all models, perfectly matching the sensible-heat-dominated heat output of servers and UPS equipment. It reduces unnecessary dehumidification loss, cuts overall power consumption and helps facilities meet global green data center energy compliance standards.

2.5 Wide Capacity Range & Scalable Parallel Deployment

      Two model tiers cover cooling output from 28.5kW up to 185.3kW. Units can be run in parallel to add cooling capacity gradually alongside server rack expansion, easing upfront capital pressure for phased data center construction.

2.6 Open Communication for Centralized O&M

      Standard communication ports are reserved for integration with environment monitoring systems, enabling remote parameter setup, real-time operation tracking and instant alerts for hydraulic faults, filter blockage and climate anomalies to support unattended operation.

      All operation logs of every deployed SLDS series chilled water precision CRAH unit can be aggregated into your unified data center management dashboard.

5. Key Commercial Benefits for Operators

     1.Central plant cooling drastically reduces CAPEX on outdoor units and piping, and cuts labor cost for routine decentralized maintenance

    2 .Stable climate control slows performance degradation of servers and UPS batteries caused by temperature & humidity fluctuation

     3.Filter clogging alarm and automatic hydraulic adjustment predict risks in advance and lower unplanned downtime

     4.Multiple capacity options plus parallel layout support phased expansion and optimize initial project investment

     5.High sensible cooling improves PUE performance to satisfy international energy audit and green data center certification requirements

      For cross-border large data park construction projects, the standardized SLDS series chilled water precision CRAH unit unifies cooling architecture and O&M standards across distributed global sites.

6. FAQ

Q1: Can these CRAH units connect to third-party central chiller control systems and UPS monitoring platforms?

A: Standard industrial communication interfaces are available for integration with mainstream chiller management systems, UPS brands and data center O&M platforms when you deploy the SLDS series chilled water precision CRAH unit.

Q2: Can multiple units be installed in parallel for future capacity expansion?

A: Yes, parallel operation is fully supported. You may add extra units gradually as your server load grows without revamping the whole chilled water piping system.

Q3: How does the filter clogging alert function work?

A: The differential pressure switch monitors pressure difference across the G4 filter and sends remote alerts once dust buildup exceeds the preset threshold for scheduled maintenance.

Q4: Is this solution suitable for overseas campus colocation data centers?

A: This centralized chilled water CRAH design is a mainstream option for large colocation parks, fully aligned with international data center construction norms.
