Plate heat exchanger for drying linen in hotels and laundry industry

ホテルやランドリー業界におけるリネン乾燥用プレート式熱交換器

Application principle:
During the washing and drying process of linen, steam or hot water enters one side of the plate heat exchanger as a high-temperature fluid, while the air to be heated (for drying) enters the other side as a low-temperature fluid. Through a plate heat exchanger, the high-temperature fluid transfers heat to the low-temperature fluid, causing the air temperature to rise and achieving the purpose of preheating.
Plate heat exchangers have good thermal conductivity and can effectively transfer the heat of steam to linen, improving thermal efficiency. This means that the drying process of linen can be completed faster or energy consumption can be reduced with the same energy consumption.
