How does it compare with vacuum extractor?
It works due to the suction created by millions of micro-capillary pores in the material. LAXMI HELEXTRA rolls can squeeze out 30% more liquid than traditional rubber rolls. Improved liquid removal enables energy saving or attainment of higher speeds of drying. The roll can be used either singly next to hard roll, or in pairs for maximum expression. LAXMI HELEXTRA rolls are effective at high machine speeds (30-50m/min), where vacuum extraction equipment cannot be used. LAXMI HELEXTRA does not require any additional power to operate. Hence, considerable amount of power can be saved if substituted to vacuum extractor.
