Stainless Steel Coil for A Quite Big Air Handling Unit

In air handling units, Stainless Steel Coils are a common heat exchange element used to regulate the temperature, humidity and quality of air. These coils are typically used to heat, cool or dehumidify air to meet specific comfort or process requirements.

Construction and Principle of Operation

Stainless steel coils are usually made of stainless steel, which gives them excellent resistance to corrosion and high temperatures. The construction can be either a single-layer coil or a multi-layer coil.

The working principle is as follows:

Heating: when the air needs to be heated, hot water or steam flows through the stainless steel coil. At this time, the hot medium inside the coil will transfer heat to the outer wall of the coil, and the air is heated when it passes through the coil.

Cooling: Similarly, when air needs to be cooled, cold water or refrigerant flows through the stainless steel coil. At this point, the cold medium inside the coil transfers cold to the outside of the coil and the air is cooled as it passes through the coil.

Dehumidification: For the dehumidification process, the surface temperature of the cooling coil is lower than the dew point temperature of the air, which causes the water vapour in the air to condense into water droplets, which are removed and reduce the humidity in the air.

Advantages

The advantages of stainless steel coils in air handling units include:

CORROSION RESISTANCE: Stainless steel material has good corrosion resistance and can be used for long periods of time without rusting.

Hygienic: Stainless steel is easy to clean and maintain, making it particularly suitable in environments where high hygiene standards are required.

High temperature performance: stainless steel materials can withstand high temperature conditions and are suitable for applications requiring high temperature heating.

Long life: Due to the nature of its material, stainless steel coils have a long service life, reducing the frequency of replacement and maintenance.
