DX Coil

DX Coil

DX stands for direct expansion cooling. In DX cooling equipment, a refrigerant coil is placed directly in the supply air stream. As the refrigerant evaporates and expands, it removes energy, lowering the temperature of the supply air stream.

Evaporator coils, commonly referred to as DX (direct expansion) coils, are used to cool and/or remove moisture from air streams. A liquid-vapor mixture of refrigerant enters the coil and cools the air as it evaporates, eventually leaving the coil as a gas.

DX Cycle

The refrigerant DX Cycle (also known as Vapor Compression Refrigeration System – VCRS), Is a closed & sealed circuit and has been around for over 200 years. It comprise 4 components: a Compressor, an Evaporator a Condenser and an Expansion Device.

If the user vapes very regularly, the coil will quickly dry out in patches, or completely. When this occurs, it will often burn out. Many vapers unknowingly use the wrong e-liquid with the wrong type of device, leading to frustration when their coils keep burning without clear reason.
