The Problem: Metal Corrosion During stopages, turbines tackle very severe corrosion risks. If appropriate measures are not taken, corrosion can cause a lot of damage to many different system components, and can result in major disruptions to the restart.  Rate of corrosion accelerates, when Relative Humidity crosses a critical level. Above this level industrial pollutants, like Sulphur-Di-Oxide, also, enhance the corrosion rate as the corrosion is faster when surfaces are exposed to polluted air in combination with high relative humidity.   Why is Corrosion a Problem? Corrosion cause ..read more

Humidity can be measured in several ways: either by relative humidity, absolute humidity or dew point.  Below we try to explain the different ways of measuring humidity.    Absolute Humidity: Relative humidity is the most common measurement, However, in order to understand relative humidity, it is helpful to first understand absolute humidity. Absolute humidity is the water content of air. In other words, the mass of water vapor divided by the mass of dry air in a volume of air.  It does not take temperature into consideration. Absolute humidit ..read more

Many manufacturers struggle to maintain consistent humidity levels in their facilities during the hot summer months. 2021 forecast to very extremely humid it is time to ensure your manufacturing process is not disturbed. In a number of factories, steam and humidity are everyday byproducts of various industrial processes; if not properly maintained, excess humidity levels can cause a number of issues, resulting in delays, safety risks, and additional expenditures. Even reliable air conditioning may not be enough to achieve the relative humidity needed as the percent relative humidity rises as ..read more

It is commonly acknowledged by preservation experts, that inappropriate water vapour in the air are a real threat to the preservation of documents, artifacts and relics.  Humidity can lead to moisture damage, bacterial growth and corrosion of the object to be preserved. Once, this has occurred the object will probably never return to its former condition. NEWS: World's Oldest Mummies damaged by humidity In an recent article posted in the Guardian, the world's oldest mummies are degrading at a rapid rate due to higher than normal humidity levels in the atmosphere.  Ralph Mitchell, a H ..read more

Your HVAC system is a breeding ground for mould and bacteria that can cause sickness, increased labor costs and energy inefficiency. Harmful biofilm builds up in HVAC coils and drain pans, where the cool, wet conditions are ideal breeding grounds for mold and bacteria. This gluey matrix degrades both performance and IAQ, circulating microorganisms implicated in allergies, asthma and disease. Once a Steril-Aire solution is installed, biofilm is eliminated. Our high-output lamps deliver the UVC intensity required to sustain this germicidal action over time. Savings on operating costs alone can d ..read more

Ice build up is caused when moist air enters the cold store. Sometimes there can be thin layers of ice which has the appearance of snow. When the moist air comes in to contact with cold surfaces such as floors, walls and evaporator coils, the water vapour in the air condenses to form water and then freezes to form ice. Moisture typically enters the cold store or freezer during door opening times. As the doors open warmer, more moist air in naturally drawn into the cold store, which in turn causes fog, condensation, ice and snow. Most cold stores require constant opening and closing of doors to ..read more

Maintaining optimal climate for a museum collection can be complicated. There are many things to take into consideration: general climate, comfort of the visitors and types of items in the collection. Conservation of historical items is vital. Natural history specimens, textiles, paper, books, manuscripts, print or any other ethnographic material are subject to a natural process of decay. They are all organically based, and therefore susceptible to mould growth and rapid deterioration, particularly in a warm, moist environment. By removing the moisture from the environment the damaging effec ..read more

Ever wondered why high humidity in winter isn't uncomfortable, but high summer humidity makes the air feel sticky?   The reason: Temperature   In Auckland it is currently hot, muggy and wet. It rains a lot in winter but why is the air uncomfortable when it is humid in summer?  The reason is temperature. Warmer temperatures can hold more moisture than colder temperatures.  Thus. it is temperature that makes all the difference; cold winter air, even when saturated, contains far less moisture than warm summer air. Relative humidity, a common measure of atmospheric mo ..read more

Sports facilities are at a greater risk of high humidity. This is due to their warm temperature and the high number of people often in a compact area. Uncontrolled humidity in these environments can cause many issues, including fog, mould, odours, bad ice (Ice Skating) or structural degradation. Not to mention the high energy costs. This is why dehumidifiers have become essential in sports facilities. The principle operation of a desiccant dehumidifier is very simple, in that moisture is absorbed onto a desiccant wheel as air passes through and the air leaves as d ..read more
