RBNV-I Vertical Package Dyeing System AIR PAD PRESSURIZATION RBNV-I, as all Loris Bellini dyeing machines, is Air Padded since the beginning of the 50’s. RBNV-I dyeing machine can be pressurized at 5 Bar at low liquor temperature. The relevant advantages to this solution are: Ecology and environment: Lower Consumption. Only pump and carrier volumes are flooded, with reduction of liquor ratio to a minimum water, steam and power consumption. Substantial savings are realized in term of cooling water, steam and electric power. Low Emissions. The air pad operates as a double chamber to reduce heat emissions in the dye-house. NO external Expansion Tank means no emission of chemical vapours. NO external Expansion Tank means no continuous external circulation, thus liquor expansion volume realized directly into the autoclave. Dyestuff exhaustion is perfectly equalized. Air pad pressurization allows to inject dyestuffs and chemicals directly into the main liquor circuit by means of single tank or a multi tank colour-kitchen. Air Pad Pressurization allows the machine to be standard equipped with dynamic HYDRO-EXTRACTION DEVICE by compressed air. VAT DYEING: During cotton dyeing with VAT dyestuffs the dyeing liquor is not subject to a continuous oxidation by external air.
