The ZL-10T's PVC drift eliminator captures water droplets entrained in the rising air stream, limiting drift loss to <0.005% of circulation flow. Industry-standard towers without eliminators lose 1-3% of circulation flow as drift — a massive water waste in water-stressed regions.
Annual water savings per ZL-10T with proper drift eliminators versus un-eliminated tower:
Without eliminators (3% drift): 0.03 × 7.81 m³/h × 16 hr/day × 365 days = 1,368 m³/year = 1,368,000 liters/year wasted as drift.
With ZL-10T eliminators (0.005% drift): 0.00005 × 7.81 × 16 × 365 = 2.28 m³/year = 2,280 liters/year drift loss.
Net annual savings: 1,365,720 liters/year per ZL-10T. At industrial water rates of USD 0.0015/liter, that's USD 2,049/year saved per tower in makeup water costs alone.
For a 50-tower facility, the ZL-10T's drift performance saves 68 million liters/year — equivalent to the annual water consumption of approximately 1,000 households.
The ZL-10T qualifies for LEED v4 BD+C (Building Design + Construction) credit SS Water Use Reduction, contributing up to 4 points toward LEED certification. The credit calculation framework:
Baseline water consumption (industry-standard cooling tower): Cycles of concentration 3, drift 3%, no side-stream filtration.
ZL-10T design water consumption: Cycles of concentration 5, drift 0.005%, optional side-stream filtration reducing cycles further to 7-10.
LEED credit calculation: Percent water savings = (Baseline − Proposed) / Baseline × 100. The ZL-10T's reduced drift and higher cycles deliver 35-50% water savings versus baseline, sufficient for 4 LEED points when combined with low-flow fixtures and other water-conserving strategies.
For projects targeting LEED Gold or Platinum certification, the ZL-10T's water performance contributes measurably to the Water Use Reduction prerequisite and credit.
The ZL-10T's 0.37 kW fan motor delivers 85 CMM of airflow for 7.81 m³/h water flow — a specific fan power of 0.37 / 7.81 = 0.047 kW per m³/h. Normalized to refrigeration ton: 0.37 kW / 10 RT = 0.037 kW per RT.
Annual electricity consumption for the ZL-10T fan motor at 16 hr/day operation: 0.37 × 16 × 365 = 2,161 kWh/year. At industrial electricity rates of USD 0.10/kWh: USD 216/year per tower.
For a 50-tower facility, total annual electricity for cooling tower fans: 108,000 kWh/year. Source mix: if the facility uses 30% renewable energy, the carbon footprint attributable to ZL-10T cooling is approximately 30 metric tons CO2/year (50 towers × 2,161 kWh × 0.4 kg CO2/kWh × 70% grid factor).
For sustainability reporting, the ZL-10T's contribution to Scope 2 emissions is captured under facility electricity consumption.
The ZL-10T's fan assembly is engineered for 60 dB(A) sound pressure at 1 meter distance. This meets EU machinery directive 2006/42/EC noise requirements (typically <75 dB) and US OSHA 29 CFR 1910.95 occupational noise limits (8-hour TWA 90 dB).
For residential or commercial mixed-use installations where the cooling tower is closer than 30 m to occupied spaces, the ZL-10T's 60 dB rating typically requires no additional acoustic enclosure. For installations within 10 m of occupied windows, an acoustic enclosure (USD 280 factory option) reduces noise to 50 dB at 1 m.
The ZL-10T's noise level is dominated by the 635 mm axial fan at 1,440 rpm. Lower noise variants (not currently offered for the 10 ton class) would require slower fans or larger diameters, both increasing tower height and cost.
For installations where the ZL-10T serves a water-cooled chiller, the cooling tower is refrigerant-agnostic — it cools water, not refrigerant. However, ESG-focused facilities transitioning away from high-GWP refrigerants should verify chiller compatibility with low-GWP alternatives:
R-134a (GWP 1,430): Industry-standard for medium-temperature chillers. Compatible with ZL-10T + water-cooled chiller configuration.
R-410A (GWP 2,088): Common for air-cooled chillers; less common in water-cooled. Compatible.
R-407C (GWP 1,774): Lower-GWP alternative for medium-temperature. Compatible.
R-22 (GWP 1,810, phased out): Legacy refrigerant. Compatible but should be replaced for ESG compliance.
Natural refrigerants (R-717 ammonia, R-744 CO2, R-290 propane): GWP <10, increasingly specified for ESG-conscious facilities. Compatible with ZL-10T, but require specialized chiller design (not generic off-the-shelf).
The ZL-10T cooling tower does not directly use refrigerant; only the paired chiller consumes refrigerant. Therefore, the ZL-10T's ESG profile is dominated by water and electricity metrics.
The ZL-10T's FRP shell is composed of fiberglass reinforcement (60% by weight) and polyester resin (40%). FRP recycling is technically feasible but industrially limited — most end-of-life FRP is currently landfilled.
Service life: 15-20 years under normal operating conditions (proper water chemistry, UV-protected gel coat, mechanical loading within spec).
End-of-life options:
1. Mechanical recycling: Shred FRP into 10-50 mm particles for use as filler in concrete, road base, or new FRP products (limited commercial infrastructure).
2. Thermal recycling (cement co-processing): FRP can substitute for raw materials in cement kilns. Mineral content becomes part of clinker; organic content provides thermal energy. Available in Europe and parts of Asia.
3. Energy recovery (incineration): FRP has calorific value similar to coal (15-20 MJ/kg). With modern emission controls, FRP incineration with energy recovery is a viable end-of-life option.
For ESG-conscious facilities, specifying FRP cooling towers with documented service life and recyclability supports circular economy reporting under GRI 301 (Materials) and similar frameworks.
With proper PVC drift eliminators, drift loss is <0.005% of circulation. Versus industry-standard 3% drift, annual savings: 1,365,720 liters/year per tower. At industrial water rates (USD 0.0015/liter), that's USD 2,049/year per tower.
Yes. The ZL-10T qualifies for LEED v4 BD+C SS Water Use Reduction credit (up to 4 points). The 35-50% water savings versus baseline supports 4 LEED points when combined with low-flow fixtures and other water-conserving strategies.
0.37 kW fan motor at 16 hr/day operation = 2,161 kWh/year per tower. At USD 0.10/kWh industrial rates: USD 216/year per tower. For a 50-tower facility, total annual electricity: 108,000 kWh/year.
60 dB(A) at 1 meter distance. Meets EU Machinery Directive 2006/42/EC noise requirements (<75 dB) and US OSHA 29 CFR 1910.95 occupational noise limits (8-hour TWA 90 dB). Optional acoustic enclosure reduces to 50 dB for installations <10 m from occupied spaces.
Yes. The ZL-10T cooling tower is refrigerant-agnostic. For low-GWP chiller pairings (R-134a, R-410A, R-407C, R-717 ammonia, R-744 CO2, R-290 propane), the ZL-10T provides primary cooling regardless of refrigerant selection.

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.
