Coil is a kind of heat ex changer that is used to cool or heat forcibly flowing air with water, glycol solution, steam or heat conduction oil as the medium. It is extensively applied in hot air heating, drying, cooling, dehumidifying and other works in such industries as light industry, building, chemical engineering, machinery, textile, printing & dyeing, electronics, food, starch, medication, metallurgy and painting. Different models of heat ex changer should be selected according to the actual working conditions.
Heat exchange tubes use various forms. Commonly used are carbon steel hot-dip galvanized tubes (also divided into round tubes and oval tubes), aluminum alloy tubes, and stainless steel tubes (also divided into 314/316 round tubes and wave tubes); aluminum alloy type evaporation Type condenser is a new type of energy-saving new generation product suitable for ice machine refrigerant condensation, the applicable pressure range is 0-5MPa; stainless steel tube evaporator condenser is mainly used in the corrosive gas cooling and condensation process of some chemical plants.
The shell of the refrigerated evaporator condenser is generally spray-coated with galvanized sheet. Later, because it is not resistant to corrosion, aluminum zinc-plated sheet is gradually sprayed. The latest used on the market is aluminum magnesium-zinc sheet. This sheet has the characteristics of stainless steel.
