Structural principle

This air heater adopts a sleeve type structure of copper tube with aluminum sheet, which is compact in structure, has a large heat exchange area per unit volume, and has high thermal efficiency. It is used in the paper drying process section of paper mills.

An air heater is a heat exchange device that uses steam, hot water, thermal oil, or hot ethylene glycol solution as a heat medium to heat cold air. An air cooler is a heat exchange device that uses cold water or low-temperature ethylene glycol solution as a refrigerant to cool hot air. It generally consists of heat exchange tube bundles, air inlet and outlet tube boxes, and supports.

scope of application

Widely used in various working conditions that require hot and cold air, such as HVAC, electricity, steel, chemical, biopharmaceutical, automotive coating, papermaking, textile, food processing, etc.

Technical Parameter

The commonly used types of heat exchange tubes usually include sleeve type, wound type, rolled type, embedded type, welded type and other structural types. The main materials for base pipes include carbon steel pipes, stainless steel pipes, copper pipes, aluminum pipes, composite pipes, etc; The main materials for fins (ribs) include carbon steel sheets, stainless steel sheets, aluminum sheets, copper sheets, etc. Pipe boxes are generally made of carbon steel or stainless steel materials.
