Abstract
A heat exchanger, by which the entire ironing surface of a commercial laundry flatwork finisher is uniformly heated, includes a chest ironing surface backed by a fluid cavity that is in turn externally heated by a gas burner. A temperature control element is immersed in the heat transfer fluid and reduces temperature differential across the entire ironing surface allowing the machine to be operated continuously and more efficiently.
