Dedicated Outdoor Air Systems
Desert Aire's DOAS solutions help overcome the moisture load challenges posed by outdoor ventilation air. Hot and humid, cool and rainy our units don’t care...
Contact UsThe most energy efficient method to remove moisture is through the use of a dedicated outdoor air system (DOAS) that lowers the dew point temperature of supply air to below 55°F (Note: dewpoint is a measurement of absolute moisture in the air). Delivering this dry air also helps absorb existing moisture inside a facility that may come from people, infiltration, or other factors. Desert Aire DOAS options allow you to design the highest energy saving solution for your compliance to ASHRAE 62.1 code ventilation requirements for new construction and renovation projects. These design options let you custom tailor a DOAS solution to fit your facility’s needs, including:
- Brute force or Energy Recovery of exhaust air
- Control Strategies to provide better energy efficiency
- Choice of Condensers
- Air cooled
- Water cooled
- Water Source Heat Pump including Geothermal
- Heating options include:
- Gas heaters
- Electric resistance
- Hot water or Steam Coils
- Heat Pump Mode on Water Source Heat Pump models
Medical Grade Hospital & Healthcare Dehumidification Systems
Desert Aire engineers have long recognized the health and performance imperatives of creating effective and efficient, medical grade dehumidification systems for hospitals.
Our hospital grade dehumidifier solutions attend to your needs as a healthcare provider for indoor environments that help patients heal, and to maintain ideal comfort levels for everyone in the building.
Why Healthcare & Hospital Dehumidification is Necessary.
In addition to protecting building spaces from mold, mildew and moisture, our hospital grade dehumidifier systems also provide many other advantages to hospitals, such as:
- Preventing the growth of bacteria and other microorganisms – Lack of proper dehumidification creates a breeding ground for bacteria, mold, fungi and other harmful microorganisms. This can lead to problems such as odors, allergies, respiratory issues, infections and other health problems.
- Controlling the spread of airborne diseases – High humidity levels make it easier to spread airborne diseases such as influenza and tuberculosis. Our healthcare dehumidification systems can help to reduce humidity levels and make it easier to control the spread of these diseases.
- Creating a more comfortable environment – High humidity environments can be uncomfortable for patients, staff, and visitors. Dehumidification can help to reduce humidity levels and create a happier, more comfortable and healthier environment for everyone in the healthcare facility.
- Preventing damage to buildings and equipment – Problems such as corrosion can occur when areas aren’t properly dehumidified, which causes damage to buildings and equipment. Additionally, because of their strategic application, our medical grade dehumidifier systems also works to protect ductwork surfaces from condensation in building regions separate from regular conditioned spaces.
Make your healthcare facility healthier, safer, more efficient, and save money on operating costs with Desert Aire’s medical grade healthcare and hospital dehumidification systems.
Dehumidification Systems for Grocery Stores, Retails Stores & Supermarkets
High humidity and condensation are the enemies of grocery stores and supermarkets in the refrigeration aisles. Condensation forming on the refrigeration equipment makes the equipment work harder consuming greater amounts of energy and will shorten the life of this equipment.
Desert Aire’s dehumidification solutions for supermarkets, grocery & retail stores will assist in eliminating the humidity problems that lead to fogging on refrigerated display case doors, condensation on the refrigeration equipment and buildup of frost on frozen food packaging.
Our energy-efficient, easy-to-maintain retail store dehumidifier solutions also ensure that your stores have the indoor air quality that meets the season-to-season needs of shoppers and building codes.
Importance of Dehumidification Systems in Stores
When conditions around refrigeration cases in a supermarket, grocery store or mini market exceed 55°F (13°C) dew point (72°F (22°C) dry bulb/55% relative humidity) condensation can begin to form on the cases and doors. When condensation forms on these appliances, this can cause higher electrical consumption, unwanted condensation dripping on the product, poor visibility of the product, and water on the floor that can lead to slip and fall accidents.
Maintaining the dew point in these areas at or below 52°F (11°C) is an acceptable method to control condensation. Desert Aire dehumidifiers can reduce the humidity levels in these areas and therefore improve the product appearance and reduce the risk of accidents in these refrigerated locations.
Library, Museum & Archive Dehumidification Systems
At Desert Aire, we pursue the mission of preserving your permanently valuable records, materials and archives with our dehumidification systems for museums, libraries and any other building storing archives.
Desert Aire’s dehumidification solutions help Libraries, Archives, Museums and Galleries prolong the lives of their records and materials by creating finely tuned indoor environments within buildings and repositories that are the perfect condition for whatever material is being stored.
Conventional air conditioning cools the air temperature, but fails to properly control humidity. Our energy-efficient museum, library and archive dehumidification systems remove excess moisture to protect the contents of libraries and archives from mold, mildew, yellowing, curling and more.
Additionally, when building codes require outside air, Desert Aire’s dehumidifiers remove excess humidity and supply the air at the temperatures and humidity levels you specify.
Materials That Need Proper Dehumidification to be Preserved:
- Wood
- Paper
- Cotton
- Linen
- Wool
- Silk
- Parchment
- Leather
- Fur
- Feathers
- Ivory
- Bone
- Horn
Ideal Humidity Conditions for Items Stored in Libraries & Museums
| Material Type | Relative Humidity |
|---|---|
| Paper | 35-55% |
| Most photographic materials | <15% <35% |
| Plastics | 30-45% |
| Teeth, bone and shell | 30-55% (lower than 30% can result in mechanical damage) |
| Stable pyrite and pyritic specimens Unstable pyritic specimens |
<45% <20% |
| Freeze dried specimens | <40% |
| Unstable or corroding metal Stable Metal |
<15% <35% |
| Naturally mummified animal remains | 15-20% |
The relative humidity for most National Park System collections is 45 – 55% relative humidity, ideally ± 5% from the set point.
What Happens When Materials Aren’t Stored in The Proper Humidity?
Archive environments with excessive relative humidity (above 65%) are subject to mold and/or swelling and deformation of organic materials, metal corrosion and increased pests.
Excessively dry conditions can cause drying of materials that results in shrinking and cracking in materials such as ivory, teeth or wood, and dehydration of some minerals.
Fluctuating humidity causes cycles of shrinking and swelling of organic materials and can potentially result in deformation or/and fractures, causing layered materials to delaminate and/or buckle, and loosening of joints of components.
