Heat Reduction Devices – A Thorough Guide

Cooling towers or heat rejection devices are used everywhere, be it homes or offices. There are various types of heat reduction devices available in the market.

  

What is a heat reduction device? And how does it work? 

A heat reduction device or water tower extracts waste heat from the building to the atmosphere through a cooling water stream to lower temperatures. The type of heat rejection through a wet tower is termed as evaporative. It allows a small portion of the water being cooled to evaporate into a moving air stream, which provides significant cooling to the rest of that water stream. 

The air from the water stream is then transferred to the air that raises the temperature of the air and relative humidity level to 100 percent. The air then gets discharged into the atmosphere. The evaporated heat rejection device or equipment such as wet towers is commonly used to provide significantly lower water temperatures than dry or air cooled heat rejection devices can give. 

In scientific terms, it is almost similar to when you would have seen something hot to get rapidly cooled down by putting water on it. FlowMatrix is a trustworthy company providing its services for over 30 years now; they have everything that is required in the maintenance of a water-based reduction device. 

Here are a few cooling tower components that are required to enable its smooth functioning. 

• Instrumentation 

The instrumentation system found in most cooling towers includes slow down rate, flow meters for wet tower makeup water, thermocouples for cold and hot water measurement of temperature, water level switches for cold and hot water basins, and vibration switches. These are the basic components, which should be checked regularly. 

• Fan motor

The next important part of a heat reduction device is the fan motor. Refinery and petrochemical based heat reduction device applications require explosion proof fan motors. This is due to the potentially leaky heat exchanges. The fan motors should have an overload and earth fault relay protection systems. 

• Nozzles 

Another tool required in wet heat reduction devices is nozzles. These are mostly made out of plastic. The plastics are unusual, as they are made of glass filled nylon, ABS, PVC, and polypropylene plastics. Nozzles allow for uniform distribution of hot water, so maintaining them is very important. 

• Distribution valves

The distribution valves are a part of heat reduction devices, which allows it to regulate the flow of hot water to be evenly distributed in cells. The valve body in the heat reduction device is manufactured withstand corrosive environments, but checking their brittleness and working regularly is a must.

• Driveshafts 

The drive shafts are required to transmit power from the motor's output shaft to the gear reduction unit's input shaft. This task makes the drive shaft an integral part of the system thus, you should check it almost daily.  

FlowMatrix provides all the required parts as well as maintenance of a cooling tower that would help in its smooth functioning. They offer you the best solution when it comes to cooling tower refurbishment.
