RST—B series heat exchanger is made of copper tube or stainless steel tube with aluminum fin
or copper fin, it adopts the advanced mechanical tube expansion technology, and double
flanging edges structure, mechanical tube expansion made the tubes and aluminum fin edges
tight to improve the high heat transmission coefficient. The reasonable water recycling, tube pitch,
and pitch of fins has made the heat exchanger small air resistance, light and compact structure .
It is widely used in air conditioners, cooling, dehumidification ,and heating projects.
