ZL-15T 15 Ton Industrial FRP Counter Flow Cooling Tower - Data Center
The ZL-15T FRP counter flow cooling tower delivers 52.75 kW heat rejection at 15 refrigeration tons with 11.7 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-15T.
The ZL-15T 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 52.75 kW heat rejection supports approximately 15 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-15T can be deployed in twin-tower configurations where each tower provides 50% capacity with full redundancy. The tower's compact 1180mm × 1760mm footprint minimizes data center mechanical room space requirements.
Data center capacity planning with the ZL-15T cooling tower requires matching tower capacity to peak IT load plus redundancy margin. For a 1 MW data center (18 ZL-15T 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-15T provides 52.75 kW of heat rejection, requiring only 11.7 m3/h of makeup water per tower. The tower's small footprint (1180mm × 1760mm) 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-15T's standardized design simplifies maintenance training and spare parts inventory across all cooling installations.
Data center cooling requires mission-critical reliability to ensure 99.999% uptime. The ZL-15T 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-15T provides 52.75 kW heat rejection at design conditions; for N+1 redundancy, two towers provide 105.5 kW combined capacity with single-tower failure tolerance. For 2N redundancy (full duplication), four towers provide 211.0 kW capacity with no single-point-of-failure. The ZL-15T's MTBF (Mean Time Between Failures) exceeds 50,000 hours for the 0.37 kW fan motor, providing high reliability with scheduled bearing replacement every 7-8 years.
Data center cooling infrastructure requires continuous monitoring to detect performance degradation and prevent unplanned downtime. The ZL-15T 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-15T to facilitate seamless integration with Schneider Electric, Honeywell, Johnson Controls, and Siemens BMS platforms.
The ZL-15T 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-15T condenser water) to maintain supply air temperature. This configuration reduces energy consumption by 30% compared to traditional perimeter cooling. The ZL-15T provides 52.75 kW condenser water cooling capacity sufficient for 5 typical CRAC units operating at full load.
The ZL-15T 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-15T cooling tower.

Quick Specs: ZL-CT factory-direct industrial cooling tower with multiple types and capacities, high-efficiency design, CE certified. Best for industrial cooling applications and large-scale manufacturing. A cooling tower dissipates heat from industrial or air - conditioning systems. Its working principle involves spraying hot water onto packing to form a water film, while air flow carries away heat from the water to lower its temperature. The cooled water is recyclable, saving water resources and reducing costs. There are various types, such as open and closed cooling towers. Open ones contact outside air directly, making water prone to contamination but with lower costs. Closed ones have water circulating in sealed pipes, ensuring cleaner water but usually at a higher price. Cooling towers play a key role in fields like power plants, chemical plants, and data centers, helping maintain system operation and improve energy utilization efficiency.
