Even when incorrectly loaded, the Joos presses offer maximum operational safety. With its unique design the pistons are not bolted to the press table. Instead they dynamically act on a milled contact surface under the pressing table. A column guide prevents the platen from tilting or being displaced. Synchronous operation of the platen is provided by a high-precision toothed rack parallel guidance system. This technique provides the platen with a full range for expansion in all directions. The Ökotherm is also equipped with an A.B.S. Safety System to prevent damage to the heating plates and/or platen caused by closing the press onto forgotten or incorrectly positioned objects on the platen. In such a case, the press will automatically open before there is time for any damage to occur. It eliminates most of the problems caused by uneven or mis-loading of the press.

The Joos Ökotherm can be equipped with a patented heating system which takes hot water as the heat source and uses it in the Ökotherm heating platen. The combination of different NE-profile systems with specific heat conductor profiles results in an extremely light heating platen. To reach the same temperatures as conventional heating platens, this small mass consumes up to 60% less energy. The water permanently circulates throughout the heating platen and in doing so, regulates the optimum temperature spread across the surface of the anodized cover plates.
