These systems typically produce air with a dew point no lower than 5☌ (41☏). Systems with refrigerant dryers pass the compressed air through a cooled heat exchanger, causing water to condense out of the air stream. Compressed air systems without air drying capabilities tend to produce compressed air that is saturated at ambient temperature. Pressure dew point is referred to when measuring the dew point temperature of gases at pressures higher than atmospheric pressure.ĭew point temperatures in compressed air range from ambient down to -80☌ (-112☏) in special cases. The dew point at the measurement point will be different from the dew point in the process.ĭew point relates to non-pressurized, atmospheric air (atmospheric dew point). This is important because changing the pressure of a gas changes the dew point temperature of the gas.īecause water vapor pressure and dew point are increased by air compression, it is critical to take this into consideration if you are bleeding the air to atmosphere before taking a measurement.

It refers to the dew point temperature of a gas under pressure.

The term “pressure dew point” is encountered when measuring the dew point temperature of gases at pressures higher than atmospheric pressure. So, before we continue, it is necessary to distinguish between “dew point” and “pressure dew point.”ĭew point is related to non-pressurized, atmospheric air (atmospheric dew point). However, that same point of saturation is affected by the pressure. When you’re drying plastics to make soda bottles, excessive moisture can result in brittle bottles with a cloudy finish.Īir quality is critically important to the end result of the process.ĭew point is focused primarily on temperature and relative humidity. When air is pressurized, humid air condenses and forms water droplets, which can lead to rust – and this can end up in with the food. For example, if you’re using a filling gas to fill up packs of ham, you don’t want anything in there that isn’t supposed to be there. On packing lines in the food and drinks industry, clean, dry air is an absolute must to maintain hygiene and preserve end-product quality. In semiconductor production, wet gases in compressed air systems can lead to problems such as low yield and poor reliability, while dust in the air can cause the products to short circuit. Poor-quality air – i.e., air that contains dust, other particles, or water – will result in a poor-quality paint finish, and therefore a wasted product that can’t be sold. The quality of the air you use is critically important to the end result of the process. The use of a pressure dew point monitoring system allows you to be sure you are reliably maintaining the desired moisture level in a compressed air system. Modern facilities using compressed air can identify and avoid those problems simply by keeping an eye on dew point.ĭew point monitoring can be achieved by installing high-quality dew point sensors and monitors in the compressed air system. If more water vapor is added beyond this point, it will result in condensation.Ĭondensation in pressurized air is a big problem because it causes blockages in pipes, machinery breakdowns, contamination and freezing. This maximum amount is called the water vapor saturation pressure. At any temperature, there is a maximum amount of water vapor that the air can hold. Quality Air Critical to Production and Productsĭew point is simply the temperature to which air must be cooled for the water vapor within to condense into dew or frost. What follows is a review of dew point and methods for measuring it with compressed air systems.ĭew point measurement ensures energy efficiency and helps lower the cost of ownership of compressed air systems. For compressed air systems, nothing offers a better return on investment than dew point measurement for ensuring energy efficiency and lowering the cost of ownership. Compressed air is one of the largest consumers of energy, which accounts for approximately 75% of the lifetime cost of a compressed air system.įortunately, energy saving opportunities are also everywhere, it just takes a little effort to recognize them. Think of it like electricity – a power source that drives conveyers, packaging lines, spray-painting equipment, metal presses – the list goes on and on.

In industry, compressed air is everywhere.
