( Brand: Evapco ), ( Manufacturer Part Number: ATW91B )
The ATW91B GPM closed-circuit cooling tower, manufactured by Evapco in 1993, is a highly efficient and reliable cooling system designed for industrial applications with a cooling capacity of 145 tons and a heat load of 440 tons. This cooling tower features a closed-loop design, which is ideal for applications where water conservation is a priority due to the recirculation of water within the system.
This cooling tower operates on the wet-fill, induced draft natural circulation principle. It features a vertical design and stands at approximately 50 feet in height, making it a compact yet effective solution for cooling industrial processes. The basin size measures 8 feet by 15 feet, providing enough space for the recirculating water to evenly distribute heat and promote effective cooling.
The ATW91B GPM cooling tower is constructed primarily of fiberglass reinforced plastic (FRP) material. This high-quality material ensures durability, resistance to corrosion, and low maintenance requirements. The tower is built with a modular design, allowing for easy installation, dismantling, and transportation.
The cooling tower's fans are mounted on top of the tower and are driven by a 50 horsepower motor. This design provides for optimal airflow and promotes efficient cooling. The fans are equipped with weather protection and adjustable pitch for optimal performance under varying weather and load conditions.
The cooling tower's system also includes a makeup water feed and blowdown system. This ensures that the system maintains a consistent water level and remains free of minerals and impurities that could negatively impact the cooling process. The blowdown system effectively removes these impurities from the recirculating water to maintain a high-quality cooling water supply.
Additionally, the tower is equipped with a drum type fill, which provides efficient water distribution and evenly distributes hydraulic forces on the fill. This results in minimal water splashing and noise, promoting a quiet and efficient cooling environment. Furthermore, the design of the fill allows for quick and easy access to the mechanical equipment, simplifying maintenance and inspection.
The ATW91B GPM closed-circuit cooling tower is a reliable and effective solution for industrial applications requiring high cooling capacities and water conservation. Its durable design, easy maintenance features, and efficient cooling performance make it an economical choice for businesses and industrial processes alike. With a history of proven performance and reliability, the Evapco ATW91B GPM closed-circuit cooling tower continues to be a trusted and innovative solution for industrial cooling applications.
Buying a used 145-ton Evapco loop cooling tower (ATW91B GPM model, closed basin design from 1993) comes with several pros and cons that potential buyers should consider.
Pros:1. Cost-effective: Buying a used cooling tower can be a cost-effective solution compared to purchasing a new one. The significant price difference can help save a substantial amount of capital upfront.
2. Reliability: Evapco cooling towers are widely recognized for their robust design and reliability. The loop design, in particular, is known for its efficiency and low maintenance requirements. A used cooling tower from a reputable manufacturer like Evapco may still offer reliable performance.
3. Quick installation: Since used cooling towers have already been manufactured and tested, they can be installed more quickly compared to a new one. This can help save time and potentially reduce labor costs, making the overall project more efficient.
4. Reduced lead time: That being said, buyers must keep in mind that finding a used cooling tower that precisely matches their specifications and requirements might take longer than ordering a new one. However, the quicker installation process once the tower is found can make up for the additional lead time.
Cons:1. Limited customization: Since used cooling towers are typically sold as is, buyers might not be able to make customizations to meet their specific application needs. This could potentially impact system performance and overall efficiency.
2. Maintenance costs: Older used cooling towers may require more frequent repairs and maintenance, potentially increasing operational costs. Although the initial cost savings might be substantial, these additional maintenance costs should be weighed against the savings from purchasing a new cooling tower.
3. Energy efficiency: Used cooling towers may not meet the latest energy efficiency standards. Although the loop design of the Evapco cooling tower is known for its efficiency, buyers should be prepared to offset any energy savings that might be gained by investing in upgrades or improvements to increase the cooling tower's efficiency.
4. Unknown history: Buying a used cooling tower means taking on the previous usage history and any potential wear and tear. Buyers should conduct thorough inspections and consider investing in third-party evaluations to assess the condition of the tower before making the purchase.
Conclusion:When considering purchasing a used 145-ton Evapco loop cooling tower, it is crucial to weigh the potential benefits against the drawbacks. While this used cooling tower comes with cost savings and quicker installation, these advantages must be balanced against factors like limited customization, increased maintenance costs, potentially lower energy efficiency, and the unknown history of the tower.
Before making a decision, potential buyers should inspect the cooling tower thoroughly and consider the upfront savings against the potential long-term costs. If the cooling tower is found to be in good condition and meets the application requirements, this used cooling tower can provide a cost-effective solution to cooling needs. In contrast, if the required maintenance and potential energy upgrades outweigh the initial price savings, a new cooling tower might be a better investment.
