Closed-Circuit Cooling Towers

Baltimore Aircoil Co. added new models to its induced-draft FXV product line, expanding its closed-circuit cooling tower offerings. Originally consisting of all single-air-inlet cells, the line now includes larger, higher capacity dual-air-inlet models. The thermal performance of all are independently certified by the Cooling Technology Institute (CTI), eliminating the need for onsite field tests. The company's Combined Flow Technology employs a combination of coil and wet-deck heat transfer surfaces to increase performance.

Counterflow/Crossflow Cooling Towers

Ecodyne designs and builds counterflow/crossflow cooling towers for utilities and process industries. Complete cooling tower services also are offered, including reconstruction, upgrade, inspection, testing and replacement parts.

Cooling Tower

Marley Cooling Technologies' rotomolded polyethylene hot and cold water UniBasin technology has a leak-proof, corrosion-proof 10-year warranty. Available in gear or belt drive, the NC cooling tower is available up to 1,812 tons in a single cell, which is reported to be the largest factory assembled tower on the market.

Modular Cooling Tower

Tower Tech Inc. builds evaporative water cooling towers for power and process cooling applications. The modular design allows the tower to accommodate any heat load from 5,000 to 500,000 gal/min. Features include built-in redundancy, low emissions and low maintenance requirements and operating costs. Towers contain the company's Variable-Flow rotary spray nozzle, which delivers a square spray pattern and adjusts automatically to varying water flows and pressures. A water collection system allows all mechanical equipment to be installed beneath the tower, which prolongs motor life and eases maintenance access.

Crossflow Cooling Tower

Tecumseh Cool Products offers corrosion-resistant, galvanized steel units in 5- to 125-ton capacities. Designed to ease maintenance and provide maximum efficiency, the tower's PVC nozzles ensure that water entering the tower is distributed uniformly over thermoplastic media material. Field-erectable, the tower has a structural steel base ready for rooftop, elevated or ground-level installations. Its small footprint makes it suitable for applications with limited space.

Fiberglass Cooling Towers

Dura-Lite is designed for a long service life with minimal maintenance. Offered by U.S. Cooling, the tower is built to eliminate leaks, provide good UV protection and withstand seismic and hurricane winds. Its exterior can be custom-colored to match any surrounding. Interior components can be tailored to meet abrasive water chemistries or water that may foul other towers. Unit is lightweight and can be hoisted in one piece to the top of roofs or field-assembled where hoisting is not practical.
