![]() LLDPE can also withstand environmental stresses that affect how long the tubing lasts. A blended form of the polymer called linear low-density polyethylene (LLDPE) offers even greater flexibility and conformability. It offers increased tensile strength, stability and uniformity. Used widely for pneumatic equipment, polyethylene is semi-rigid, which allows it to work with push-to-connect fittings that have no clamps. For example, nylon should not be used with barbed fittings, as this will result in leaks, while nylon should be used for car wash tubing exposed to direct sunlight, as polyethylene breaks down more quickly when exposed to UV radiation. Tubing exposed to direct sunlight should also be made from materials resistant to ultraviolet (UV) radiation. It’s also necessary that they work with the specific fittings used to attach them to other equipment and other tubing throughout the car wash. Materials & Applications for Car Wash TubingĪll car wash tubing must be able to withstand the cleaning agents they carry. Wraparound brushes for cleaning the front, sides and rear.įittings connect car wash tubing and hoses to all this equipment.Water treatment systems that recycle water.Undercarriage wash applicators that apply a large amount of water (and sometimes rust inhibitors) to remove dirt and salt to the car’s underbody.Tunnel controllers that regulate the timing and application of cleaning equipment and agents.Top brushes that descend to scrub the vehicle’s top.Mitter curtains that oscillate to clean top surfaces.Low side washers that clean the rocker panel along the side of a car. ![]() High pressure sprayers that use pressurized water to remove dirt from places brushes and other scrubbing equipment cannot reach.Dryers that blow water off of vehicles at the end of the wash cycle. ![]() Conveyors that pull or push a car through the tunnel.Car wash doors, which are often made from polycarbonate or vinyl.Arches that dispense water and cleaning solutions as cars pass under them.Air compressors that deliver pressurized air to pneumatic tools and equipment.While hoses are reinforced and used for high-pressure applications, tubing generally transports gases or liquids at lower pressures.Įquipment that makes up a modern automated car washes includes: While many people use “tubes” and “hoses” or “tubing” and “hosing” interchangeably, they are not the same. These systems are made up of machinery connected by car wash tubing and hoses, which are attached via fittings. Today’s car washes use a variety of equipment that works together in harmony to clean a vehicle. As new services were added, car wash tubing and hoses needed to become increasingly chemical-resistant to withstand the treated water, soap, wax and other cleaning agents that move throughout the system. Modern car washes now offer even more flexibility, including full-service, express, flexible and self-serve tunnels, with each offering different price points. The 1980s saw a resurgence of car washes that gave the consumer choice as to the extent of the wash their cars received. Though the 1970s saw a decline in the automatic car wash industry due to soaring gas prices, both automated wheel cleaners and polish-and-wax buffers appeared during this decade. ![]() Progress continued during the 1960s, as recirculating water systems, roller on-demand conveyors, soft cloth friction washing and wraparound brushes were introduced. By 1959, more efficient equipment made the whole process quicker. Nozzles slathered soap onto vehicles while automatic scrubbing brushes replaced manual ones. A fifty-horsepower air blower then finished the job by drying most of the water off.Īs car wash technology advanced during the 1950s, fully automated car washes came into being. As the car passed through the tunnel, three sets of manually-operated brushes scrubbed the car clean. Using a conveyor belt that hooked to the car’s bumper, they moved vehicles through a tunnel while an overhead sprinkler system sprayed water down on them. Automatic car washes got their start in Hollywood in 1946, taking most of the manual labor out of washing cars. ![]()
