Optimal shaped windshield washer tanks

Typically, in passenger cars, the windshield washer tanks are three to five litres. For buses and coaches, however, the volume of these tanks is much larger. Often, they contain 30 litres or more. This gives the designers a challenge because the highest priority is to get as much space as possible for the passengers and their luggage. Because of that, a washer fluid tank must often be oft fitted in an odd-shaped space that is left at the final stage. The unique advantages of rotomoulding come in handy here. The design freedom with this technology is huge. It creates the opportunity to utilize the available space and create the desired large volume windshield washer tanks.

Freeze-resistant windshield washer reservoirs

Normally a windshield wiper fluid container is filled with water and anti-freeze. This is called an ethylene glycol water mixture. Polyethylene has an excellent chemical resistance against ethylene glycol water mixtures. When no anti-freeze is added by accident, the tank content may freeze, and the ice will expand. The extreme tough polyethylene material will withstand this and will not crack.

A one-piece multi-function washer fluid tank

To pump the anti-freeze to the windscreen or head lights, a pump is mounted on the windshield washer reservoirs. To create space for the pump a recess is moulded in the tank where the pump fits in exactly. With some simple snap nocks no additional assembly parts are needed. In the bottom of the recessed area a hole is drilled, where the suction foot of the pump is mounted with a watertight rubber collar.

Furthermore, a filling neck with screw thread for a screw cap is also formed at the top of the tank, or a hose tail over which a filling hose can be mounted. Mounting feet are also formed to be able to mount the tank in the bus. In short, we create a one-piece tank with all necessary functions integrated.
