120 â?? value in minutes of eis classification periods (120 minutes resistance). Fä±re damper is a part of fire wall and it must be closed during fire.Fire dampers should have thermal sensors. The damper has special gasket providing tightness between wall and casing, intumescent gasket, 30 mm thick calsium silicate board, high temprature resistant silicone.
70 kg/m3 density, 20 mm thickness fire rated rockwool is used between the blade walls. Fire dampers are used for the purpose of preventing the fire and smoke from diffusing to other places with air ducts in building ventilation systems. The fusible link mechanism that is presented at the damper provides the blade in the damper to close by driving with the return spring when it reaches at 72°C and prevents the fire from diffusing to other places. Also, it can be controlled with servomotor automation system, as well. The fusible link is fixed to the damper on the face where damper handle is presented in such a way that it can be replaced easily.

Air to water heat pipe heat exchanger is mainly to heat water using the hot air from heat recovery, it can be used for domestic water, water for boilers or production process. The exchanger is constructed using a partition in the middle to separate the exchanger, both sides are independently sealed. A single heat pipe can be replaced. While working the hot air flows from one side to the other side, the heat pipe absorbs heat. Meanwhile, cold water flows from the reverse side, the heat pipe releases heat, thus heating the cold water from the reverse side. The outlet temperature is not lower than dew temperature.

The cooling tower fan is located at the top of the cooling tower, which is directly connected with the motor or indirectly connected with the gearbox and pulley. The fan draws the hot air in the cooling tower after heat exchange from the top and guides the low-temperature air to enter from the air inlet of the bottom cooling tower.
As a professional cooling tower manufacturer, we also provide plastic or FRP (fiberglass) cooling tower fans or fan blades at good prices. You can surely pick out what you need from the different types of industrial cooling tower fans below.
Closed Circuit Cooling Tower
Closed circuit cooling tower (also known as an evaporative air cooler or closed cooling tower) is the tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating water heat exchange to ensure the cooling effect.
AUVC not only provides different shapes of cooling towers used in industries, such as round shape cooling towers and square cooling towers, but also offers closed cooling towers and open circuit cooling towers as well. The type of closed circuit cooling tower is widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries.
How do closed circuit cooling towers work?
Closed-circuit cooling towers make it possible to separate the evaporative circuit from the process circuit (customer circuit). A stainless-steel plate heat exchanger attached to the cooling tower, in its dedicated room, allows a glycol-free operation, and a simplified and unequalled ease of maintenance.
The closed circuit cooling tower works as follows
On the process side to be cooled (customer loop), the water to be cooled enters a plate heat exchanger connected to the tower and is cooled and discharged. The primary loop is closed and never comes into contact with air.
On the secondary side of the cooling tower, the water is sucked out of the pool by a pump and circulated through a stainless steel plate heat exchanger. The water leaving the exchanger is piped to the top of the unit. This water is graded and evenly dispersed over the exchange surfaces by dispersers (also known as water distribution nozzles). Air driven by fans (axial or centrifugal) enters from the lower part of the cooling tower, is heated and saturated with water and exits from the upper part, passing between the exchange surfaces.
Under the effect of the surface tension of the filler ladder, the water spreads uniformly and flows away over the entire height of the tower. The exchange surface is thus increased.
The water cooled by forced ventilation falls freely into an inclined pool located at the bottom of the unit.
Cooling Tower Motors
Cooling tower motor is a new type of energy-saving and environmental protection improved motor, with protection grade of IP55, insulation grade of B, and power supply voltage of 380V and 50Hz. Generally, a closed waterproof motor is used in the cooling tower, which can operate for a long time in outdoor humid and high temperature environments. The cooling tower motor material is cast iron and aluminum shell.
Derived from one of the most rugged motor platforms used in the most demanding industrial applications, direct drive motors are the right solution for operation in hot and humid environments in towers. Direct drives are ideally suited for cooling towers, air-cooled condensers and air-cooled heat exchangers.
