FRP Round Counterflow Tower
Rotomolded fiberglass shell, low noise fan, ideal for rooftops and tight plant rooms.

Cooling tower manufacturer · Est. 2003
Cooling towers built for continuous duty, not mild weather.
Counterflow, crossflow, closed-circuit and large industrial towers from 5 to 5,000 m³/h. Each unit is thermally selected against your wet-bulb, flow rate and approach — then molded, assembled and tested in our own works before it ships.

Product range
Six tower families, one selection standard
From a single rooftop unit to a field-erected industrial tower — same thermal calculations, same material traceability, same after-sales file.
Square Crossflow Tower
Modular FRP panels, easy site assembly, generous access for fill cleaning and inspection.
50–1,500 m³/hFlow rate
3–5 °CApproach
Closed Circuit Tower
Sealed coil loop keeps process water clean — for chillers, furnaces and heat exchangers.
30–1,200 m³/hFlow rate
Zero driftProcess side
Open Cooling Tower
High-efficiency film fill and low-pressure spray nozzles for general industrial cooling.

Why ZHOUNENG
Engineering first, catalogue second
Most tower failures are selection errors, not manufacturing errors. We start with your duty point and work backwards.
01
Thermal selection, not guesswork
Every quotation carries a calculation sheet: wet-bulb, range, approach, flow and fan power — signed by an engineer.
02
In-house FRP molding
We mold our own shells and basins. No outsourced panels, no mismatched resin batches, no waiting on a third party.
03
Tested before it ships
Hydrostatic leak test at 1.5× design pressure, fan vibration check, and a full run-in on every assembled unit.
04
Spares for 15 years
Fill, nozzles, drift eliminators and drive components stay available long after the warranty window closes.

Applications
Where our towers run
Six industries, six different duty profiles. Selection rules change with them — ours are built around the application, not a single catalogue page.

How we work
From duty point to commissioning
Four stages, one engineer responsible for your file from first email to final handover.
Site data & consultation
You send flow, inlet/outlet temperature, wet-bulb, altitude and layout constraints. We flag anything that will hurt performance.
Thermal selection
Selection report with tower size, fan power, pressure drop, water volume and a dimensioned general arrangement drawing.
Manufacturing & FAT
Production schedule with weekly photo reports. Factory acceptance test with your inspector welcome on site.
Shipment & commissioning
Export packing, container loading plan, and remote or on-site commissioning support for the first start-up.

Quality control
Every unit leaves with a test file
Six inspection hold points are signed off between raw material intake and container loading. You get the complete record — not a certificate that says “trust us”.
- Resin and glass batch traceability for every molded shell
- Hydrostatic test at 1.5× design pressure, 30-minute hold
- Fan balance and vibration check under load
- Fill and drift eliminator sampling per ASTM test methods
- Dimensional check against approved GA drawing
- Pre-shipment photo report with serial numbers
