YWCT can offer our customers two alternatives for field-erected cooling towers (~1,000 m³hr-100,000 m³hr):

Pultruded FRP structure
Fiberglass field-erected cooling towers are high-quality cooling towers with powerful cooling capacity, designed to serve the heavy-duty heat removal demands of various industrial sectors.
Pultruded fiberglass structure is ideal for the wet, corrosive environments typical of cooling towers: It is strong yet light, doesn’t corrode when exposed to moisture or chemicals, and due to its UV resistance, won’t deteriorate when exposed to sunlight. Whether counterflow or crossflow design, they are structured of continuous composite fiberglass-pultruded sections that comply with CTI’s STD 37 and conform to ASTM E84D with a flame spread rating below 25.

YWCT provides our customers with scale drawings of the concrete cement basin, including locations and production drawings of all pipe fittings in 2D or 3D. The size of a single cell ranges from 6mx6m to 16mx16m. When the concrete basin is ready on site, YWCT sends one of its site managers to supervise erection (usually conducted using local teams).

Pultruded FRP cooling towers have become an alternative solution to traditional concrete cooling towers, as in many cases they cost less and their erection time is much shorter than that of cooling towers made entirely of concrete. In addition, pultruded FRP towers in many cases offer superior corrosion resistance.

Concrete structure
Concrete cement cooling towers are designed for heavy industrial applications such as power plants; petrochemical and chemicals plants; and refineries of various kinds. YWCT provides our customers with scale drawings of the concrete cement structure, including locations and production drawings of all pipe fittings in 2D or 3D. The size of a single cell ranges from 6mx6m to 16mx16m. In most cases, our customers (who are familiar with the local market and regulations) choose to take over the civil engineering and the concrete work. Our engineering department guides the concrete construction process from beginning to completion, ensuring that on-site work meets all requirements. While construction is taking place, all relevant parts of the cooling tower are purchased or manufactured and delivered to the job site. When the structure is ready, YWCT sends one of its site managers to supervise the final stage of the cooling tower erection, which includes fitting of the cooling towers with fill, louvers, fan, motor unit, and fan stack (the work is usually conducted using local teams) until the cooling tower is operational.

Choosing a concrete structure ensures the end user long product life for the cooling tower, and may be the least costly solution for certain customers who already work with a concrete contractor, particularly in locations where labor is less costly.

As an option, YWCT can offer additional features for its field-erected cooling towers:

• Low-noise fans
• Complementary subsystems: filtration system, I&C, circulation pumps, water treatment systems, heat exchangers, VFD, and more
• Elevated basin for optimal use of space
• Rainfall attenuating
• Solutions for low-quality water
• Additional veil layers for increased corrosion resistance (for pultruded FRP structure)
