NST Crossflow Open Cooling Tower
Crossflow Design · Low Air Resistance · Easy Maintenance · Ideal for Large-Scale Installation
Product Overview
The NST Series Crossflow Open Cooling Tower utilizes a crossflow design where air flows horizontally through the fill while water flows downward. This crossflow contact ensures high heat exchange efficiency and low air resistance. The tower features a robust structure and is easy to maintain, making it ideal for HVAC systems, industrial refrigeration, process cooling, and various other scenarios.
- High-efficiency PVC fill, large heat dissipation area, and high heat exchange efficiency.
- Crossflow design with low air resistance, effectively reducing fan energy consumption.
- Modular structure for easy transportation and rapid on-site assembly.
- Single unit capacity ranges from 50 to 800 m³/h, scalable in parallel.
- Optional low-noise configuration available to meet urban environmental requirements.

Frequently Asked Questions
Q: What is the difference between crossflow and counterflow cooling towers?
A: Crossflow towers have air flowing horizontally across the falling water, while counterflow towers have air flowing vertically against the water. The NST Series crossflow design offers lower air resistance, reduced fan energy consumption, and easier maintenance access.
Q: How do I select the right NST model for my project?
A: To select the optimal model, you will need to know your design wet-bulb temperature, water flow rate, inlet/outlet water temperatures, and available installation space. Our sales engineers can provide professional selection support based on your specific site conditions. Contact us at sales@newinequipment.com.
Q: What water quality is required for the NST Series?
A: Standard industrial water is suitable for the NST Series. The tower is equipped with large-orifice, non-clogging PP nozzles which significantly reduce blockage risks. For applications with poor water quality, we offer optional high-low variable flow nozzles to ensure uniform water distribution.
Q: Are customized dimensions or materials available?
A: Yes. We offer flexible configuration options to meet specific project requirements, including 304/316 stainless steel construction, all-FRP casing for highly corrosive environments, and customized dimensions to fit site constraints.
