ZL-2 steam air heater is consists of 7 parts: steel-aluminum radiator fin tube + electric steam valve + drain valve + insulation box + fan+ Fresh air damper + electric control system.

It is specially designed to support the left and right circulation drying room. For example, the 100,000 kcal model drying room, it is equipped with 6 fans, three on the left and three on the right.

When the three fans on the left rotate clockwise, the three fans on the right rotate counterclockwise in a cyclic alternating manner, forming a relay, the left and right sides serve as air inlets and outlets alternately, taking out all the heat generated by steam heater.

It is equipped with an electric fresh air damper to supplement fresh air in coordination with the dehumidification system in the drying room/drying place.
