Independent CTI-certified performance letter and third-party Witnessed testing available for projects requiring verified performance
The ZL-350T cooling tower delivers 1231.0 kW of heat rejection at design conditions of 37C inlet / 32C outlet / 27C wet-bulb. Capacity is factory tested per CTI Standard 201 (ATC-105) with independent third-party verification available for projects requiring certified performance curves. Off-design performance at higher approach temperatures follows standard psychrometric interpolation with derating curves provided in the submittal package.
The ZL-350T is rated at 27C wet-bulb with 5C approach. For tropical installations with higher wet-bulb (32C+), the cooling tower requires derating of approximately 8-12 percent per 1C wet-bulb increase. ZILLION provides site-specific derating calculations based on ASHRAE Handbook climatic data for the project location.
Counter flow geometry places the air inlet at the bottom and water distribution at the top, creating true counter-current heat transfer. This delivers 15-20 percent higher thermal performance than cross flow designs of equivalent fan power, particularly at high approach temperatures. The ZL-350T counter flow design also reduces plume formation by 30 percent versus cross flow configurations.
At 110 percent of design flow, the approach temperature increases from 5C to approximately 6.5C. At 80 percent of design flow, the approach tightens to 4C with the same range. The pump head loss curve at 16 kPa design point is published in the performance submittal with full 0-150 percent flow characterization.
Yes, ZL-350T thermal performance is factory tested per CTI Standard 201 (ATC-105) with independent verification. Each tower ships with a CTI certification letter showing measured kW, range, and approach at design conditions. Third-party certification is available for projects requiring Witnessed or Field Certified performance per CTI ATP-105.
A chemical processing plant in Eastern China deployed ZL-350T counter flow cooling towers for reactor temperature control in a 200-ton per day polymer line. The engineering team specified ZL-350T after psychrometric analysis confirmed 140.7 kW heat rejection capacity at the 27C design wet-bulb with 5C approach. CTI Standard 201 thermal certification letter supported the EPC contractor submittal package, and the third-party verified performance curve enabled the plant to qualify for energy efficiency rebate from the local utility. Process integration included plate heat exchanger isolation, VFD pump control, and Modbus integration with plant DCS. First-year operating data showed ZL-350T matching design performance within 2 percent tolerance.

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.
