Thermocylinders from Hoerbiger-Origa, Glendale Heights, Ill. (hoerbigeroriga.com), are rodless pneumatic cylinders (OSP Series) designed for extreme-temperature applications. Generally, rodless cylinders have a maximum operating temperature of approximately 150°F. This new version handles temperatures to 500°F.

The unit's unique barrel design lets coolant pass through the entire length of the cylinder. The barrel functions similar to a water jacket, keeping heat away from internal plastic and rubber parts. To prevent leakage, special high-temperature gaskets seal between the endcaps and cylinder barrel. To distribute coolant evenly through the cylinder, a special manifold attaches to the face of the endcap. It divides coolant into five separate flow paths, and combines them back to one path upon exiting.

High-temperature coolant leaves the cylinder and enters a heat exchanger with an attached blower. Low-temperature fluid returns to the cylinder. The unit removes approximately 9,240 Btu/hr for a 40-mm bore cylinder with a 65-in. stroke. A chiller can also be used to control coolant temperature and flow.

The Thermocylinder permits rodless cylinders in high-temperature applications, such as glass-foundry oven doors, hot-roller-press applications, and bakery ovens.
