WesternFlag – ZL3 Steam Hot Air Heat Exchanger (Top air outlet & bottom air inlet)
Product Overview
Heat source : Steam
Airflow direction: Top Outlet & Bottom Inlet
Matching Drying Room ： XG Series Hanging Type Drying Rooms
Features： Equipped with dehumidifying fan, fresh air damper & waste heat recovery ｜ High energy efficiency｜ Precise temperature & humidity control
Advantages
1. Uncomplicated design and effortless setup.
2. Substantial air capacity and minimal air temperature variation.
3. Durable stainless steel electric heating fin tube.
4. Steel-aluminum fin tubes with elevated heat exchange efficiency. The base tube is fashioned from seamless tube 8163, which is resilient to pressure and long-lasting.
5. Electrical steam valve governs the intake, automatically shutting off or opening based on the preset temperature, thereby ensuring precise temperature control.
6. Ventilator immune to high temperatures and high humidity, with an IP54 protection rating and H-class insulation rating.
7. Integration of the dehumidification and fresh air system results in remarkably small heat loss through the waste heat regeneration device.
8. Automatic fresh air replenishment.
9. Applications:
- Heating systems for drying rooms, dryers, and drying beds
- Temperature control for vegetable and flower greenhouses
- Warm air supply for livestock breeding houses (chicks, ducklings, piglets, calves, etc.)
- Space heating for factories, shopping malls, and mining sites
- Heat supply for powder coating, sandblasting, and paint baking processes

Working Schematic Diagram
1. ZL3 Series steam hot blast furnace consists of valve group for drainage, return air grille, steam valve group, dehumidification fan, electric air valve, waste heat recovery device, support, steam heat exchanger and outlet.
2. Low‑temperature air enters the unit through the electric air valve and return air grille. It firstly passes through the waste heat recovery device for pre‑heating.
3. Steam is fed into the steam heat exchanger via the steam valve group. Condensed water is discharged by the valve group for drainage.
4. Air is further heated by the steam heat exchanger. High‑temperature air flows out from the outlet for drying process.
5. The dehumidification fan discharges humid exhaust air out of the system.
6. Waste heat recovery device recycles residual heat from exhaust gas to improve overall energy‑saving performance.
