ZL-20T 20 Ton Industrial FRP Counter Flow Cooling Tower - Data Center
The ZL-20T 5°C wet-bulb approach at design WB 27°C is critical for data center chiller integration:
Chiller performance: 5°C approach delivers 32°C condenser water at design conditions. Water-cooled chillers achieve rated capacity at this temperature. Each 1°C reduction in approach saves 2-3% chiller compressor power.
PUE impact: For a 100 kW data center load, the ZL-20T enables chiller COP of 4.5 at design conditions, supporting PUE 1.3-1.4 when combined with efficient UPS and IT equipment.
Approach degradation tolerance: ZL-20T maintains 5°C approach up to WB 30°C. Beyond this, supplementary cooling or hybrid configurations maintain chiller performance.
Annual energy impact: Maintaining approach within 1°C of design saves approximately USD 1,500-2,000 per ZL-20T annually in reduced chiller compressor power.
The ZL-20T 70 kW heat rejection capacity covers the following data center configurations:
Single rack (10 kW): ZL-20T covers 7 racks at full load. Typical high-density pod deployments.
Medium-density deployment (5 kW/rack): ZL-20T covers 14 racks. Standard enterprise data center room configuration.
Mixed-density (3-15 kW/rack): ZL-20T covers 5-20 racks depending on actual IT load profile. Common in hybrid cloud and HPC environments.
Modular deployment scaling: Adding ZL-20T units scales cooling capacity linearly. For 200 kW data center, 3 ZL-20T units provide N+1 redundancy at 100% capacity with one tower offline.
Edge data center: Single ZL-20T supports 50-100 kW edge deployments with appropriate containment and redundancy.
For Tier-rated data center cooling, the ZL-20T supports N+1 redundancy configurations:
Tier III: Multiple ZL-20T units with concurrent maintainability. Each tower rated for 70 kW; N+1 configuration supports 140 kW nominal with one tower in maintenance.
Tier IV: 2N redundancy with fault tolerance. Two independent ZL-20T cooling loops, each rated for full data center load. Loss of one loop leaves full capacity on the second.
Reliability metrics: ZL-20T MTBF >50,000 hours per unit. MTTR 4-8 hours for major component replacement. Annual availability >99.9% with standard maintenance.
Spare parts strategy: For Tier III/IV facilities, on-site critical spares (fan motor, eliminator section, float valve) ensure rapid MTTR.
The ZL-20T reliability profile meets Tier-rated data center cooling requirements with appropriate redundancy design.
Data center facility engineers integrate ZL-20T into BMS for continuous monitoring:
Monitored parameters: Fan motor amp draw (1.5 A nominal), leaving water temperature (32°C target), basin water level (float valve status), basin water temperature (5-50°C range).
Alarm thresholds: Amp draw >1.8 A (bearing wear alert), leaving water >35°C (capacity exceeded), basin level low (makeup water failure), basin temperature <4°C (freezing risk in cold climates).
Trending data: 1-minute resolution data logged for capacity planning, efficiency trending, and predictive maintenance.
Control integration: Optional VFD enables fan speed modulation for partial load operation. Modbus RTU or BACnet protocol support for BMS integration.
For high-availability data centers, BMS integration enables remote operation and reduces on-site staffing requirements.
The ZL-20T supports data center hot aisle/cold aisle configurations through ZL-20T heat rejection capacity:
Hot aisle containment: Server exhaust air at 35-40°C is captured and returned to air handlers. Air handlers chill air to 18-22°C supply temperature using chilled water from chillers, which reject heat via ZL-20T.
Cold aisle delivery: 18-22°C supply air is delivered to server intakes. Chilled water flow rate 16 m³/h per ZL-20T matches the heat load profile.
Air-side economizer integration: When ambient conditions permit, free cooling bypasses mechanical chilling. ZL-20T supports hybrid configurations where the cooling tower pre-cools condenser water to enable free cooling at higher ambient temperatures.
Density optimization: ZL-20T supports data center PUE 1.2-1.4 with proper hot/cold aisle design and optimal chilled water delta-T.
For new data center design, ZL-20T capacity supports 10-30 kW per rack high-density configurations.
The ZL-20T cooling tower supports data center compliance with industry standards:
ASHRAE TC 9.9: Thermal Guidelines for Data Processing Environments. ZL-20T 5°C approach at design WB 27°C enables chiller performance within ASHRAE recommended envelope for class A1-A4 environments.
Uptime Institute Tier Standard: Topology and operational sustainability requirements. ZL-20T reliability profile supports Tier I-IV classifications with appropriate redundancy design.
Energy Star for Data Centers: ZL-20T 0.55 kW fan power contributes to PUE calculations for Energy Star certification.
LEED for Data Centers: FRP shell recyclability and IE3 motor efficiency support LEED v4 BD+C: Data Centers credits.
For data center facilities pursuing certification, the ZL-20T documentation package includes compliance verification data.

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.
