Why are there so many models of eyewash?

Eyewash was widely used in most factories, laboratories and hospitals in developed industrial countries (the United States, Britain, etc.) as early as the 1980s. Its purpose is to reduce the damage to the body caused by toxic and harmful substances at work, and it is widely used in petroleum, chemical, semiconductor industry, pharmaceutical manufacturing and places where hazardous materials are exposed.
The eyewash can be used to clean the eyes, face, hands and other parts. The shower nozzle can clean the whole body.
Eyewash is a necessary equipment for safety and labor protection. It is a necessary emergency and protection facility for occasions contacting acid, alkali, organic matter and other toxic and corrosive substances. When accidents occur, use rapid spraying. Rinse to minimize the damage.
At present, except in South China, other regions will have weather below 0°C in winter, so there will be water in the eyewash, which will freeze the normal use of the eyewash.

To solve the problem of water accumulation in the eyewash, it is necessary to use an antifreeze eyewash, an electric heating eyewash or an electric heating eyewash.
Electric heating eyewash should be used in areas that not only prevent freezing but also increase the water temperature. The electrically heated eyewash device heats the water in the eyewash device by heating the eyewash device with tropical electric heating, so that the water accumulated in the eyewash device will not freeze. It can increase the temperature of the eyewash water to a certain extent, but it cannot increase the temperature of the spray at all. (Note: The flow rate of the eyewash is 12-18 liters/min; the spray rate is 120-180 liters/min.) The electrically heated eyewash is heated by the electric heating system, so that the water accumulated in the eyewash will not freeze and can be increased The temperature of the eye wash and spray.
