Cooling Tower Water Treatment
BHD Series Square Cross-flow GRP Cooling Towers – Advanced Industrial Cooling Solutions
The BHD Series Square Cross-flow GRP Cooling Tower represents a significant leap in industrial cooling technology. By optimizing traditional structural designs with state-of-the-art mechanized processes, BHD towers deliver a perfect combination of high efficiency, lightweight durability, and stable operation. Every component is strictly tested to ensure reliable performance in the most demanding environments.
Core Technical Innovations & Quality Engineering
Our commitment to "Special Design, Special Quality" is reflected in our advanced manufacturing processes:
Seamless Spray Water Tray: Crafted using a one-time molding process, our water trays are completely seamless, effectively eliminating drips and splashing leaks.
Reinforced Frame Structure: The frame is constructed from hot-dip galvanized steel plates with a C-shaped groove reinforcement design, ensuring long-term structural integrity.
Vacuum Infusion GRP Air Ducts: Utilizing advanced vacuum introduction technology, our air ducts boast a strength and toughness increase of over 50% compared to traditional hand lay-up methods.
Precision Molded Components: We have transitioned from hand-crafting to mechanized precision. Panels are pultruded, and water tanks/corners are molded, resulting in a superior aesthetic finish and better structural consistency.
Intelligent Energy Saving & Noise Reduction
The BHD Series is designed for modern sustainability requirements:
VFD Integration: Units can be equipped with a Frequency Conversion Device, allowing the fan speed to automatically adjust based on water temperature and load conditions.
Operational Cost Savings: This intelligent regulation significantly reduces energy consumption and operating noise, lowering the total cost of ownership for the end-user.
Durability & System Protection
Anti-Algae & Bacterial Control: The semi-enclosed water chamber blocks debris and prevents direct sunlight from entering the system, inhibiting the growth of algae and bacteria to maintain water quality.
UV & Aging Resistance: The tower body features GRP protective plates coated with high-quality imported gel coat, providing excellent resistance to ultraviolet rays and extending the equipment's service life.
Modular & Scalable Design: With capacities ranging from 100 to 700 m³/h per cell, our modular design allows for multiple towers to be connected seamlessly, occupying a minimal footprint while maintaining an elegant appearance.
Pre-assembled Steel Blocks: Critical steel components are pre-welded before leaving the factory, reducing on-site welding time and ensuring safer, faster installation.
