SIPHON SYSTEMS
SIPHONS FOR COOLING SYSTEMS Equally important to consistent heat transfer in the dryer section is uniform heat reduction in the cooling section.The cooling cylinder must reduce the sheet temperature to a specific degree uniformly across the web. An effective cooling system introduces cold water and evacuates the warmer water so that the surface temperature of the cylinder remains constant. The warm water behaves similar to condensate in relation to the cylinder’s speed, and like condensate, it puddles, cascades and rims. It is necessary to introduce a mixture of water and air to provide the required pressure differential to evacuate the cylinder. For these reasons, most of the same siphon systems are equally effective in both heating and cooling applications. Deublin also offers systems designed specially for Pope reels and Press rolls.
