Standard tanks are made of stainless-steel, and are designed to handle up to a 5 liter bottle or a fluid cartridge. Bottles or cartridges are placed directly inside the tanks and pressurized with a controlled and constant pressure to feed the fluid out of the top fluid port. The bottles or cartridges can be easily replaced and the time for cleaning can be drastically reduced as the dispensed fluids never wet the inside of the tank.
This type of tank is also made of stainless-steel and can hold up to a 10 liter bottle. The tank is pressurized so that fluids can be fed out of the bottom port. Highly polished inner and outer surfaces of the tank minimize the build-up of residue, which results in clean dispensing stations.
