The PMC-285 285 Evapco evaporative ammonia condenser unit cooling tower, model number 823913, is an advanced engineering solution engineered for industrial applications where the cooling of large quantities of ammonia is required. This particular cooling tower model, developed by Evapco, an industry-leading innovator in evaporative cooling technology, exhibits exceptional performance and efficiency in ammonia cooling systems.
Design and Construction:The PMC-285 285 cooling tower is a forced-draft, natural circulation, crossflow design. This configuration provides improved circulation and better heat transfer performance by utilizing countercurrent flow between the rising water and falling ammonia vapor. The structure is constructed using high-quality materials, including fiberglass-reinforced plastic (FRP) for the tower shell, fill media, and mechanical components to ensure a long-lasting solution. The tower's rugged design can accommodate a wide operating range of ambient temperatures and pressures.
Heat Exchange and Ammonia Cooling:The cooling tower is equipped with a pleated, high-density fill media, specifically designed for ammonia cooling applications. The design increases the tower's water contact area, providing efficient and effective heat exchange between the tower water and the ammonia vapor, resulting in lower discharge temperatures. This crucial feature contributes to the superior cooling performance, maintaining consistent ammonia temperatures for optimal system efficiency and productivity.
Above the fill media, there is a forced-draft fan system which ensures efficient and continued circulation of air over the wet pack during operation. The fan system, operating via a Variable Frequency Drive (VFD), provides an optimal airflow while minimizing energy consumption. The fan design uses ER/EIS high-efficiency motors, which coupled with the VFD, results in less power usage and reduced energy costs over time.
Additional Features:The PMC-285 285 Evapco evaporative ammonia condenser unit cooling tower (model 823913) also incorporates several essential features for reliable operation. These features include:
- Easy access to internal components for maintenance via hinged access doors
- Fill media inspection access ports
- Removable passenger car battery-type moisture eliminator
- Drain nozzles for easy cleanout and water sample access
- Structural supports for adding optional fume scrubbers or deaerators
- Galvanized steel inlet and outlet connections
- Modular design for ease of transport and quick installation
