The glass fiber reinforced plastic cooling tower is corrosion resistant, high compressive strength, light weight, small size, small footprint, beautiful appearance, strong and durable, and convenient transportation, installation and after-sales maintenance. Therefore, it is widely used in various social and economic units, and is especially suitable for cooling water circulation equipment such as central air conditioning, refrigeration, air compressor stations, heat treatment furnaces and cooling processing techniques.
The circular counter-flow glass fiber reinforced plastic cooling tower is based on the counter-current gas heat exchange technology, and the filling material is based on the first-class modified polyvinyl chloride wave plate to spread the area of the water; according to the method of rotating water distribution, the water distribution is more uniform and improved Cooling function. Our factory has made partial adjustments to the styling concept of this product type to make it reliable in operation, strong and durable, and convenient to equip.
The main purpose of FRP cooling tower
(1) DBNL3 series product low-noise glass fiber reinforced plastic cooling tower-mainly used for basic cooling places such as central air-conditioning refrigeration units where the water temperature drops by 3-8 degrees.
(2) CDBNL3 series of ultra-low noise FRP cooling towers-mainly used in hotels, hospitals, public buildings and places close to residential areas that have stricter noise regulations.
(3) Medium and high temperature industrial glass fiber reinforced plastic cooling towers of GBNL3 series products-mainly used for industrial water circulation refrigeration systems with a temperature drop of 10-25 degrees.
FRP cooling tower model specification composition
There are several series of products for the circular counter-flow FRP cooling tower: DBNL3, CDBNL3, GBNL3
FRP cooling tower characteristics and selection
1. Ideation parameters:
1) The standard stipulates the working conditions: the inlet water temperature t1=37℃, the outlet water temperature t2=32℃, the conceived wet bulb temperature τ=28℃, that is, the water temperature Δt=5℃, the high cooling range t2-τ=5℃
2) Medium-temperature working conditions: inlet water temperature t1=43°C, outlet water temperature t2=33°C, conceived wet bulb temperature τ=28°C, that is, water temperature Δt=10°C and high cooling range t2-τ=6°C
3) High temperature working conditions: inlet water temperature t1=60°C, outlet water temperature t2=35°C, conceived wet bulb temperature τ=28°C, that is, water temperature Δt=25°C and high cooling range t2-τ=8°C
2. Precautions when using water flow Q, water inlet temperature t1, outlet water temperature t2 and conceptual wet bulb temperature τ, and then clarify the model specifications based on the thermal energy characteristic line. See attached table 1 and attached table 2 for thermal energy characteristic lines. For working conditions other than the line chart, it can be calculated based on thermal energy, and the volumetric mass index of the filling material is below β×ν:
When 1.2 times the nominal flow rate: β×ν=18600 When 1.0 times the nominal flow rate: β×ν=17800 When 0.8 times the nominal flow rate: β×ν=17000
3. The running net weight is measured by pressing the tower body to store more than half of the water. If it is full, it should be multiplied by 1.5.
4. The cooling towers of this series of products are used in areas where the average temperature of the coldest month is not less than -10℃. Customers whose average temperature is too low should clearly put forward regulations to prevent freezing and clean, so as to facilitate the installation of sprinkler pipe rings and prevent water from flowing. On the blinds. During the interruption of operation in winter, a heating pipe can be added to the drain.

During the interruption of operation in winter, a heating pipe can be added to the drain.
5. The turbidity of the circulating water should not exceed 50mg/liter, and should not exceed 100mg/liter in a short time. It should not contain oily dirt and mechanical debris. If necessary, adopt measures to kill algae and stabilize the water quality.
6. It is suitable for water temperature not exceeding 60℃. If it exceeds 60℃, it can be indicated when ordering. Our factory will solve it from the choice of materials. If you need a flame-retardant cooling tower, please indicate when ordering that our factory can meet the needs
If you need to know how much a 50-ton glass fiber reinforced plastic cooling tower manufacturer costs, we also need a specific analysis of the specific situation, so you have to call us for consultation.
