Product Description

Product Description

Closed-Loop Design: The closed-circuit design ensures that the process fluid remains isolated from the external environment. This prevents contamination of the process fluid, making it ideal for applications where fluid purity is crucial, such as in the pharmaceutical, food and beverage, and electronics industries.

High-Efficiency Heat Transfer: Equipped with high-performance heat exchangers, our cooling tower efficiently transfers heat rapidly. The optimized design of the heat transfer surfaces maximizes the contact area between the process fluid and the cooling medium, resulting in excellent cooling performance even under high-load conditions.

Robust Construction: Built with durable materials, the cooling tower is designed to withstand harsh operating environments. The tower body is made of corrosion-resistant materials, ensuring long-term reliability and minimizing maintenance requirements.

Variable-Speed Fan Control: Our cooling tower features variable-speed fan control, enabling precise adjustment of cooling capacity to meet actual cooling demands. This not only improves energy efficiency but also helps to reduce noise levels during operation.

Easy Installation and Maintenance: The cooling tower's modular design facilitates easy installation and maintenance. The components are designed for quick and easy access, simplifying routine maintenance tasks such as cleaning and inspection.

Cooling Tanks Parameter Table Charts

 

Parameter	Square Counter Flow Cooling Tower	Round Counter Flow Cooling Tower	Round Closed - Circuit Counter Flow Cooling Tower
Cooling Capacity	Varies widely based on size, typically from 50 to 3000 tons of refrigeration (TR). Smaller units may be around 50 - 200 TR, while large - scale ones can reach up to 3000 TR.	Similar to square counter - flow, ranging from 50 to 3000 TR. Compact models may start at 50 TR, and large industrial versions can go up to 3000 TR.	Usually in the range of 100 to 2000 TR. The closed - circuit design may limit the upper capacity due to space and heat - transfer considerations.
Water Flow Rate	Depends on the cooling capacity. For a 100 - TR unit, it may be around 200 - 300 cubic meters per hour (m³/h). For a 1000 - TR unit, it can be 2000 - 3000 m³/h.	Similar to square counter - flow. A 100 - TR unit may have a water flow rate of 200 - 300 m³/h, and a 1000 - TR unit can reach 2000 - 3000 m³/h.	For a 100 - TR closed - circuit tower, the water flow rate may be 150 - 250 m³/h. For a 1000 - TR unit, it can be 1500 - 2500 m³/h. The closed - circuit design may have a slightly lower water flow rate compared to open - circuit towers.
Approach Temperature	Usually in the range of 2 - 5°C. A well - designed tower can achieve an approach temperature of around 2 - 3°C, while standard units may have an approach of 3 - 5°C.	Similar to square counter - flow, with an approach temperature typically between 2 - 5°C. High - efficiency models can reach 2 - 3°C.	Can achieve relatively low approach temperatures, often in the range of 1 - 4°C. The closed - circuit design may allow for better temperature control and a lower approach.
Range Temperature	Typically from 5 - 10°C. For example, in a common application, the range temperature may be around 8°C.	Similar to square counter - flow, with a range temperature usually between 5 - 10°C.	Can have a range temperature of 6 - 12°C. The closed - circuit design may have a different heat - transfer mechanism, resulting in a slightly different range.
Noise Level	Can be in the range of 55 - 75 decibels (dB(A)). Smaller units may be on the lower end of the range, while larger towers with more powerful fans can reach up to 75 dB(A).	Similar noise levels to square counter - flow, ranging from 55 - 75 dB(A). The round shape may have some minor effects on noise dispersion.	Generally, closed - circuit towers can be a bit quieter, with noise levels in the range of 50 - 70 dB(A). The closed - circuit design may help in reducing noise.
Fan Power	For a 100 - TR square counter - flow tower, the fan power may be around 5 - 10 kilowatts (kW). For a 1000 - TR unit, it can be 50 - 100 kW.	Similar to square counter - flow. A 100 - TR round counter - flow tower may have a fan power of 5 - 10 kW, and a 1000 - TR unit can have 50 - 100 kW.	For a 100 - TR closed - circuit round counter - flow tower, the fan power may be 6 - 12 kW. For a 1000 - TR unit, it can be 60 - 120 kW. The closed - circuit design may require slightly more power for the fan due to the additional heat - exchanger resistance.
Material of Construction	The shell is often made of fiberglass - reinforced plastic (FRP), which provides good corrosion resistance. The fill material can be PVC or other heat - transfer - efficient materials. The frame may be made of steel with proper coating for corrosion protection.	Similar to square counter - flow. The shell is usually FRP, the fill is PVC or similar, and the frame is coated steel.	The outer shell is typically FRP. The closed - circuit heat exchanger can be made of copper, stainless steel, or other corrosion - resistant metals. The frame is steel with anti - corrosion treatment.
Dimensions	Dimensions vary based on the cooling capacity. A small 50 - TR square counter - flow tower may have dimensions of around 2m x 2m x 3m (length x width x height). A large 3000 - TR tower can be 20m x 20m x 10m or larger.	For a 50 - TR round counter - flow tower, the diameter may be around 2 - 3m and the height around 3 - 4m. A 3000 - TR round tower can have a diameter of 15 - 20m and a height of 8 - 12m.	A 100 - TR round closed - circuit counter - flow tower may have a diameter of 3 - 4m and a height of 4 - 5m. A 2000 - TR tower can have a diameter of 12 - 15m and a height of 8 - 10m.
Drift Loss	Usually less than 0.01% of the circulating water flow rate. Well - designed towers can achieve even lower drift losses, around 0.005%.	Similar to square counter - flow, with drift losses typically less than 0.01% of the water flow rate.	In closed - circuit towers, drift loss is almost negligible as the water is contained within the closed loop.
Make - up Water Requirement	Depends on the evaporation rate, drift loss, and blow - down. For a 100 - TR tower, the make - up water requirement may be around 1 - 3 m³/h. For a 1000 - TR tower, it can be 10 - 30 m³/h.	Similar to square counter - flow. A 100 - TR round counter - flow tower may require 1 - 3 m³/h of make - up water, and a 1000 - TR tower can need 10 - 30 m³/h.	The make - up water requirement for a closed - circuit tower is relatively low, mainly due to small leakage losses. For a 100 - TR tower, it may be 0.1 - 0.5 m³/h, and for a 1000 - TR tower, it can be 1 - 5 m³/h.
