ZL-30T 30 Ton Industrial FRP Counter Flow Cooling Tower - Data Center

30 Ton Cooling Tower Technical Specifications and Application Details

The ZL-30T FRP counter flow cooling tower delivers 105.51 kW heat rejection at 30 refrigeration tons with 23.4 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-30T.

5 deg C Wet-Bulb Approach: Chiller Integration for Server Room Cooling

The ZL-30T cooling tower's 5°C wet-bulb approach at 27°C design wet-bulb provides 32°C leaving water, which is ideal for water-cooled chiller integration in data center applications. This leaving water temperature enables chiller operation at 0.55-0.65 kW/ton efficiency, significantly better than air-cooled chillers (1.0-1.2 kW/ton) at the same cooling capacity. The 105.51 kW heat rejection supports approximately 30 kW of IT equipment load when paired with a high-efficiency chiller. For Tier III and Tier IV data centers requiring N+1 redundancy, the ZL-30T can be deployed in twin-tower configurations where each tower provides 50% capacity with full redundancy. The tower's compact 1650mm × 2000mm footprint minimizes data center mechanical room space requirements.

105.51 kW Heat Duty: Server Room Capacity Planning for ZL-30T

Data center capacity planning with the ZL-30T cooling tower requires matching tower capacity to peak IT load plus redundancy margin. For a 1 MW data center (9 ZL-30T units operating in parallel), the cooling infrastructure provides 1.4 MW total cooling capacity at design conditions, with N+1 redundancy leaving 1.2 MW available for IT load. Each ZL-30T provides 105.51 kW of heat rejection, requiring only 23.4 m3/h of makeup water per tower. The tower's small footprint (1650mm × 2000mm) allows outdoor installation adjacent to the data center, freeing valuable indoor white space for IT equipment. For hyperscale data centers with multiple MW cooling requirements, the ZL-30T's standardized design simplifies maintenance training and spare parts inventory across all cooling installations.

Mission Critical Reliability: N+1 Redundancy with ZL-30T

Data center cooling requires mission-critical reliability to ensure 99.999% uptime. The ZL-30T cooling tower supports N+1 redundancy configurations where multiple towers operate in parallel, allowing one tower to be taken offline for maintenance without impacting cooling capacity. Each ZL-30T provides 105.51 kW heat rejection at design conditions; for N+1 redundancy, two towers provide 211.02 kW combined capacity with single-tower failure tolerance. For 2N redundancy (full duplication), four towers provide 422.04 kW capacity with no single-point-of-failure. The ZL-30T's MTBF (Mean Time Between Failures) exceeds 50,000 hours for the 0.75 kW fan motor, providing high reliability with scheduled bearing replacement every 7-8 years.

24/7 Monitoring and BMS Integration for ZL-30T in Data Centers

Data center cooling infrastructure requires continuous monitoring to detect performance degradation and prevent unplanned downtime. The ZL-30T integrates with Building Management Systems (BMS) and Data Center Infrastructure Management (DCIM) platforms through standard protocols: Modbus RTU/TCP, BACnet MS-TP/IP, and LonWorks. Monitored parameters: leaving water temperature, water flow rate, fan motor current, fan vibration, basin water level, basin water temperature, makeup water flow, and conductivity (cycles of concentration). Alarm thresholds: high leaving water temperature (>35°C), low water flow (<80% design), high vibration (>10 mm/s RMS), low basin water level (below pump suction). ZILLION provides BMS integration documentation including register maps and BACnet PICS for the ZL-30T to facilitate seamless integration with Schneider Electric, Honeywell, Johnson Controls, and Siemens BMS platforms.

Hot Aisle Cold Aisle Configuration with ZL-30T Condenser Water

The ZL-30T cooling tower's 32°C leaving water supports modern hot aisle / cold aisle data center configurations through water-cooled CRAC (Computer Room Air Conditioning) units. Server racks are arranged in alternating hot aisle and cold aisle rows; cold aisles supply 20-25°C air to server intakes while hot aisles collect 35-40°C exhaust air. CRAC units in the cold aisles use chilled water from the chiller (cooled by ZL-30T condenser water) to maintain supply air temperature. This configuration reduces energy consumption by 30% compared to traditional perimeter cooling. The ZL-30T provides 105.51 kW condenser water cooling capacity sufficient for 10 typical CRAC units operating at full load.

ASHRAE TC 9.9 and Uptime Institute Standards Compliance

The ZL-30T cooling tower is designed and tested to comply with ASHRAE Thermal Guidelines (TC 9.9) for data center cooling and Uptime Institute Tier classification requirements. ASHRAE TC 9.9 compliance: leaving water temperature within Class A1 recommended range (18-27°C wet-bulb + 5°C approach), fan motor efficiency meeting IE3 premium efficiency standard, and noise emission below 65 dB(A) at 5 meters. Uptime Institute Tier III/IV compliance: concurrent maintainability (N+1 redundancy supported), fault tolerance (2N redundancy configurations available), and 99.999% availability through predictive maintenance. ZILLION provides documentation for ASHRAE 90.1 baseline modeling and Uptime Institute Sustainability assessment (UI SEAP) certification submissions involving the ZL-30T cooling tower.
