The ironer is one of the oldest implements for drying and pressing used in laundries. Over the years of its historical development, it has been continuously perfected technically while retaining its basic operational principles of removing moisture by transferring the linen between rolls and chests under pressure and heat.
The name SETRA denotes a design feature derived from the German acronym for "self supporting", meaning that the rolls are supported on the chests and form one functional unit. This new design ensures uniform ironing pressure throughout the whole chest, reduction in heat loss, improvements in heat transfer of about 10%, and a significantly improved operating process. Furthermore, the life of the spring padding is increased and the clothing wear is reduced because of the even ironing pressure.
Chest and Rolls
- The Chest - The chests of the Setra are designed to provide strong stable supports for the rolls. They have an extra rigidity and strength do an improved arrangement for the reinforcement ribs. The uniform shape of the chests is unaltered under all types of operating conditions and work loads. The Setra chests are characterized by their clear functional design. In contrast to conventional ironer chests, they have no protruding parts which can cause an unequal heat distribution. The Setra chests are fully insulated to prevent radiant heat loss. The heating pockets have a minimized cross section to obtain the best removal of the condensate due to the high flow rate therefore ensuring a better performance.
- The Rolls - The roll and chest of the Setra form one functional unit. The lever arms for the roll movement are attached directly to the chests. This design feature ensures permanent self centering of the rolls in the chests during all operating conditions. Thus, a completely even ironing pressure from the entry to the exit of the chest is achieved.
