ZL-60T 60 Ton Industrial FRP Counter Flow Cooling Tower - Data Center
The ZL-60T FRP counter flow cooling tower delivers 210.97 kW heat rejection at 60 refrigeration tons with 46.8 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-60T.
The ZL-60T cooling tower's 5 deg C wet-bulb approach at 27 deg C design wet-bulb provides 32 deg C leaving water, which is ideal for water-cooled chiller integration in large data center applications. The 210.97 kW heat rejection supports approximately 60 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-60T can be deployed in twin-tower configurations where each tower provides 50 percent capacity with full redundancy.
Hyperscale data center capacity planning with the ZL-60T cooling tower requires matching tower capacity to peak IT load plus redundancy margin. For a 5 MW data center (23 ZL-60T units operating in parallel), the cooling infrastructure provides 7 MW total cooling capacity at design conditions, with N+1 redundancy leaving 6 MW available for IT load. The ZL-60T's compact footprint (2100mm x 2160mm) allows outdoor installation adjacent to the data center, freeing valuable indoor white space for IT equipment.
Hyperscale data center cooling requires mission-critical reliability. The ZL-60T cooling tower supports both N+1 and 2N redundancy configurations. For N+1: two towers provide 421.94 kW combined capacity with single-tower failure tolerance. For 2N: four towers provide 843.88 kW capacity with no single-point-of-failure. The ZL-60T's MTBF exceeds 50,000 hours for the 1.5 kW fan motor, providing high reliability with scheduled bearing replacement every 7-8 years.
Hyperscale data center cooling infrastructure requires continuous monitoring through Data Center Infrastructure Management (DCIM) platforms. The ZL-60T integrates with DCIM systems 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. ZILLION provides DCIM integration documentation including register maps and BACnet PICS.
At hyperscale, the ZL-60T cooling tower's 32 deg C leaving water supports hot aisle / cold aisle data center configurations through water-cooled CRAC units. The ZL-60T provides 210.97 kW condenser water cooling capacity sufficient for 21 typical CRAC units operating at full load. For hyperscale deployments with thousands of CRAC units, the ZL-60T's standardized design simplifies maintenance training and spare parts inventory across all cooling installations.
The ZL-60T cooling tower is designed to comply with ASHRAE TC 9.9 and Uptime Institute Tier IV standards for hyperscale data centers. ASHRAE TC 9.9 compliance: leaving water temperature within Class A1 recommended range, fan motor efficiency meeting IE3 premium efficiency standard, noise emission below 70 dB(A) at 5 meters. Uptime Institute Tier IV: concurrent maintainability, fault tolerance, and 99.995 percent availability through predictive maintenance.
