BIB systems, by definition, are viewed as "remote", in reference to the product. This terminology indicates that the product is located separately from the primary dispensing equipment, either by a few inches or a few hundred feet. BIB systems fall into two basic categories: gas driven and electrical driven. Gas Driven Most BIB systems use gas pumps, driven by compressed air, to move the concentrates from the BIB to the dispensing equipment. Common sources of compressed air are 1) carbon dioxide (CO2) tanks and 2) air compressors included as part of the overall equipment system. For a schematic of a typical BIB system, click here. Electrical Driven Electric pumps have been available for some time but they have not been as popular as the gas driven pumps. For the task at hand and the working environment, gas driven pumps are generally better. With the introduction of the Wilshire Millennium, the entire industry has access to countertop units that use peristaltic, internally contained, electric pumps. This technology is a great step forward in achieving a quiet, safe and convenient dispensing system. For a schematic of a typical BIB system, click here.
