ZL-500T 500 Ton FRP Counter Flow Cooling Tower for Data Center
Hyperscale and colocation data center operators require cooling infrastructure that maintains ASHRAE TC 9.9 recommended thermal envelope conditions for IT equipment while supporting PUE (Power Usage Effectiveness) targets of 1.15-1.25. The ZL-500T 500-ton industrial FRP counter flow cooling tower delivers 1,758.5 kW heat rejection with approach temperatures as low as 3C, supporting chiller water temperatures of 12-18C suitable for cold aisle containment and rear-door heat exchanger configurations. N+1 and 2N redundancy configurations support Uptime Institute Tier III and Tier IV certification requirements, with documented N+1 deployments achieving 99.97% availability and 2N deployments achieving 99.99% availability over multi-year operational periods.
The ZL-500T supports ASHRAE TC 9.9 (2015 and 2021 revisions) recommended thermal envelope conditions for data center IT equipment. Class A1 recommended range: 18-27C dry-bulb, -9 to 17C dew-point, 40-60% relative humidity, supporting 89% of typical IT equipment operating envelopes. Class A2: 18-35C dry-bulb, dew-point up to 21C, supporting 95% of equipment. Class A3: 18-40C dry-bulb, dew-point up to 24C, supporting 99% of equipment. Class A4: 18-45C dry-bulb, dew-point up to 28C, supporting 100% of equipment with degraded performance.
The ZL-500T counter-flow design supports chilled water supply temperatures of 12-18C with approach temperatures as low as 3C, enabling cold aisle containment and rear-door heat exchanger configurations that maintain ASHRAE TC 9.9 Class A1 thermal envelope throughout the data hall. At 1,758.5 kW heat rejection capacity and 392.4 m3/h circulation flow, the ZL-500T supports 8-10 MW IT load configurations when deployed in 4-6 tower N+1 arrangements.
The ZL-500T supports PUE optimization through efficient heat rejection at elevated chilled water supply temperatures. PUE 1.15 corresponds to data hall mechanical cooling being 15% of total facility IT load. At chilled water supply temperature of 18C (versus legacy 6-8C systems), chiller COP improves by 25-35%, translating to proportional PUE improvement. The ZL-500T counter-flow design maintains approach temperatures of 3-5C even at elevated chilled water temperatures, supporting the industry trend toward higher chilled water supply temperatures and corresponding PUE improvement.
PUE measurement and verification: facility-level PUE measured per The Green Grid PUE Category 1 (basic) or Category 2 (intermediate) measurement protocols, with cooling infrastructure contribution tracked through sub-metered fan power consumption. The ZL-500T 7.5 kW fan power at 4,200 operating hours per year contributes 31,500 kWh per tower to facility-level cooling PUE component. Across a 10 MW IT load facility with 8 MW cooling load and 4 ZL-500T towers in N+1 configuration, cooling infrastructure contributes approximately 12.6% of facility total energy consumption, supporting PUE targets of 1.15-1.18.
The ZL-500T supports Uptime Institute Tier III (concurrently maintainable) and Tier IV (fault tolerant) certification requirements. Tier III N+1 redundancy configurations use 4-6 ZL-500T towers supporting 8-10 MW IT load, with full cooling capacity maintained during any single tower service event. Tier IV 2N redundancy configurations use 8-12 ZL-500T towers supporting 8-10 MW IT load, with full cooling capacity maintained during any single tower failure and concurrent maintainability of all supporting infrastructure. Documented availability: N+1 deployments 99.97% uptime, 2N deployments 99.99% uptime over multi-year operational periods.
Tier certification requirements include: Tier III requires capacity redundancy (N+1 minimum), concurrently maintainable infrastructure (planned maintenance without service interruption), and supporting infrastructure redundancy (pumps, piping, electrical). Tier IV adds fault tolerance (single component failure without service interruption) and automated response to faults. The ZL-500T modular component design supports both tiers, with on-site replacement of motor, fan blade, or water distribution nozzle assemblies achievable within 2-4 hours (within Tier IV 96-hour fault tolerance budget).
The ZL-500T integrates with hybrid cooling configurations including adiabatic pre-cooling, free cooling (air-side economizer), and heat-recovery systems. Hybrid configurations with adiabatic pre-cooling reduce ZL-500T operational hours at peak ambient conditions, supporting 15-25% additional energy savings beyond the ZL-500T standalone baseline. Free cooling integration: in climates with 1,500+ hours per year below 10C wet-bulb temperature, dry cooler or plate heat exchanger bypass routes ambient cold air directly to chilled water loop, allowing ZL-500T fans to be de-energized during favorable ambient conditions.
Heat recovery integration: ZL-500T exhaust air at 28-32C saturated temperature can be ducted to building HVAC intake for winter heating or absorption chiller regeneration, supporting 10-15% overall facility energy efficiency improvement. Integrated controls: ZILLION provides BMS integration packages supporting Modbus TCP, BACnet/IP, and LonWorks protocols for integration with data center BMS and DCIM platforms (Schneider Electric StruxureWare, Siemens Navigator, Vertiv Nform).

Operational Performance: After 14 months of operation, mean heat duty across the twelve towers measured 1,758.5 kW plus or minus 2% of nameplate, with mean chilled water supply temperature stable at 12.4C plus or minus 0.3C across diurnal load variation. PUE measured at the facility level averaged 1.18 during the monitoring period, including all supporting infrastructure.
Compliance and Validation: ASHRAE TC 9.9 Class A1 thermal envelope conditions were maintained within plus or minus 0.4C throughout the monitoring period. CTI Standard 201 thermal performance was verified independently for each tower at the 12-month mark. Plant operations reported zero cooling-related downtime events across the 14-month monitoring period, with N+1 redundancy providing graceful capacity reduction during scheduled maintenance activities.

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.
