what is steam exactly?

Steam is water which has been changed into a gas. Steam cannot be seen for it is colorless. The cloud of vapor that we see beginning about 2 centimeter from the spout of a teakettle is not steam. The real steam is in the space that seems vacant just outside the spout. The cloud we see is the water that the cooler air has changed from a gas form back into tiny water particles.

Steam is formed by boiling or by evaporation. At sea level water boils when it is heated to 100° C. Water also evaporates at lower temperatures. The steam caused by boiling is as hot as the boiling water. The steam caused by evaporation is not hot. Usually, the word steam refers to hot steam. When water reaches the boiling point, bubbles of the steam begin to rise through it and escape into the air. The temperature will remain at the boiling point until all the liquid has become gas. It requires 100 calories of heat to raise one gram of water from the freezing point (0°C) to the boiling point.

Steam fills more space than the water from which it comes, at the moment when boiling stops, the gas is 1,67 times as great in volume as the former liquid. At this stage it is called saturated steam, if heated more, it takes up even more space. Then it is known as super heated steam. The steam engine is built on this principle.

our technology

standard boiler

In the basic version of steam generators, the boiler works also as a reservoir for fresh water. With a load of water you can work about 2 hours (depending on the model). The boiler is always made of anticorrosive and anti-scale 304 stainless steel in order to guarantee duration in time of the steam generator.

unlimited autonomy

Steam cleaners with this feature have two water chambers: a pressurized boiler tank and a non-pressurized tank. That allows the operator to add water to the machine while it’s still running. Menikini’s unlimited autonomy steam cleaners are equipped with an electronic level sensor that refills the boiler when the level of water inside it is not enough. As a result, the machines avoid drops in pressure and temperature during use.

continuos fresh water inlet

Some of our industrial steam cleaners include an automatic direct water refill that connects the machine to a water pipe and refills the fresh water tank as needed. Continuos water refill systems can also be refilled manually if a water line is not available.

detergent tanks

These tanks hold and dispense cleaning chemicals. Some of our steam cleaning machines include simple handle controls that allow the operator to control the detergent and steam flow while cleaning.
