The standard designs are splashproof and suited for high traversing speeds. We also offer innovative solutions for special applications. Integral Gutter : The gutter is formed as an integral part of the rear panel of the individual boxes. This version can be manufactured in a cover width of up to approximately 2000 mm with a 2 to 3 mm thick steel sheet. With a slope of at least 5¡, this form ensures an efficient drainage and prevention of coolant entering the boxes. Separate Gutter : On special request, we can manufacture separate gutters for covers more than 2000 mm wide. In this design, a specially developed way wiper diverts the coolant along the inner side of the boxes. Due to its large cross-section, a separate gutter deflects the water optimally and even at a slope of at least 5¡ ensures the drainage of coolants entering the boxes.
