Waterbath for aerosol cans
Made in 2001 by Comes, Maschinenbau AG Switzerland.
Type: Eco 50-R.
The waterbath is used to ensure that the seals of the cans are airtight. In the waterbath the cans are immersed into warm water and thus checked for leakages.
Pamasol Willi Mäder AG is a Swiss aerosol company founded in 1965 by Willi Mäder. The firm specializes in filling and sealing machines for aerosols and spray systems.
Taerosol Oy is a Finnish firm manufacturing technical aerosols for electronics and industries. They have three aerosol series, PRF, CarEvi and First1 - product families for industry and professionals but also for consumer usage.
The sounds come from manufacturing cleaning sprays. The process includes 7 phases. At first, the valve feeding machine feeds the valves to empty cans that move with a transport belt to the aerosol filling machine. Since the cleaning spray doesn’t need any active gases, only chosen propellant is added. The aerosol filling machine adds the valves and the gases and secures the valves at the same machine. After that, the cans move to the waterbath for checking and then to the cap fitting. The labels are taped, the extra straws are added, and then the cans are packed to boxes and the boxes are taped shut.
There are strict security measurements in aerosol production and, for example, the warehouses need to be explosion proof spaces.
Max. dB. is 67.9.
