| Advantages |
- Lowest-cost cooling system design.
- Clean process water environment.
|
- Closed-loop clean water environment minimizes risk of fouling, decreasing water treatment and equipment maintenance costs
- Componentized system design facilitates maintenance.
|
- Most effective cooling at the lowest cost.
- With a remote pump/tank station, prevents freezing of tower in cold climates.
|
- For cold climates: prevents freezing of tower cell fill.
- Improved temperature stability.
- Process flow rates can differ from tower flow rates
|
- Closed-loop design minimizes risk of water fouling, decreasing direct water,
water treatment and equipment maintenance costs
- Improved heat transfer capacity lowers energy costs by as much as 30%.
|
| Disadvantages |
- Temperature fluctuations.
|
- Temperature stability.
- Evaporative cooler design is higher-cost.
- Costs related to sewage disposal, equipment maintenance and water usage
|
- Open loop design is susceptible to water fouling
- Requires regular monitoring and treatment of water supply
- Costs related to sewage disposal, equipment maintenance and water usage
|
- Costs more than traditional cooling tower system.
|
- Although the CT-CL requires a greater initial investment than traditional cooling tower systems, the total cost of ownership is lower than any other system.
|
| Cooling Technology Standard Enhancements |
- Indoor pump/tank station to eliminate risk of freezing.
- Accurate process control achieved with modulating diverting valve with PID controller.
- Can be designed to incorporate an air separator, expansion pump/tank station and electrical control panel for a hydronically sealed system.
|
- Can be designed to incorporate an air separator, expansion pump/tank station and electrical control panel for a hydronically sealed system.
|
- Cooling tower is elevated and drain is switched from the side to the bottom to minimize sediment and water fouling. Heavy water drains off automatically.
- Ensuring total water turnover, pump suction ends are extended into the tank and are cut at a 45° angle to prevent vortexing and cavitation.
- Water reservoir is located indoors to eliminate need for external heater.
|
- All of the CT Series enhancements plus …
- Water reservoir is baffled to inhibit mixing of tower and process water.
- Recirculation pump designed to pump only when cooling is necessary.
|
- All of the CT Series enhancements plus …
- High-efficiency stainless steel and plate & frame heat exchangers separates process water from tower water.
- Separation of system components reduces maintenance and repair.
