When to Consider Adding a Commercial Dehumidification System to Your Present HVAC System

When a project calls for a constant, specific room dew point above 50°F in its operation, normally the addition of a commercial A/C system is the first step. Room air conditioning will remove a certain amount of moisture while adding cool air to the space for comfort.

If the desired dew point is not met with the addition of an A/C system the best solution is to add a commercial DCA mechanical dehumidification system to achieve the desired result. Unwanted moisture can come from many sources, such as moisture released through a specific process that has to be addressed. Moisture from outdoor air being introduced into a room along with a dedicated exhaust fan is also a major factor that has to be considered, especially in wet climates. For example, moisture can enter a room through building walls and ceilings without a vapor barrier, leaky windows and doors, or doors being intermintally opened to a space. These are some of the most obvious examples but other less obvious examples may also be a factor.

Commercial indoor swimming pools and hot tubs used in motels, hotels, YMCAs, Boys and Girls Clubs, high schools, nursing homes, therapy pools, and others are always best served by DCA dehumidification systems because of the large moist load present that must be controlled.

Rooms that require a dew point of less than 50°F rely on desiccant dehumidifiers to maintain the desired dewpoint. While DCA does not carry desiccant dehumidifiers, we can supply a mechanical dehumidifier that removes the largest amount of the moisture to reliably work with a desiccant dehumidifier. The mechanical dehumidifier removes the majority of the moisture load from the room so the desiccant dehumidifier can lower the dew point to a precise range below 50°F.

Does Your Commercial Space Need Dehumidification?

Dehumidification is a vital consideration for projects that require maintaining a constant specific dew point. It can help remove large moisture loads and lower dew points that ordinary A/C systems cannot. Some typical commercial settings that use DCA dehumidification, other than indoor pools mentioned above, are the printing industry to control registry, the indoor grow industry for clean vegetable and medical marijuana growth, rooms for assembly work, warehousing, the grinding industry using water-based coolant to cool tooling, fresh and waste water treatment plants, the packaging industry for packing material that will naturally take on moisture and negatively compromise the end product.

In general terms, any industry that is negatively compromised by uncontrolled moisture will enjoy the benefits of dehumidification. At DCA, our sales engineers help facility operators determine the ideal dehumidification solution for their projects.

Benefits of Adding a Dehumidifier to Your HVAC System:

Conventional central air conditioning is the first step to reducing the moisture in a room. If a central air conditioning unit does not deliver the dew point required, a commercial dehumidification solution will solve the problem.

Hot and humid air requires more energy to cool. A dehumidifier can reduce the cost of cooling a space by reducing stress on the air conditioner and energy consumption. Reduced humidity can also improve air quality, preventing the prevalence of mold, bacteria, viruses, and dust mites.

Selecting the Appropriate Dehumidifier Options That Best Suit Your Needs

When selecting a dehumidification option that is suitable for an application, the following considerations are to be considered:

  • A vertical or horizontal configuration
  • A standard end discharge or an optional bottom or top configuration
  • Rooftop, indoor, or outdoor installation
  • Single or three-phase power
  • Electric or gas heating
  • BMS control with BACnet
  • Custom controls for integration into existing BMS
  • Provisions for outdoor air introduction to the space through the dehumidifier
  • Water cooling or remote condenser
  • Class 1 Division 2 rating to meet explosion-proof requirements
  • Increased or decreased airflow deviation from our standard catalog of dehumidifiers
  • Various other custom options to suit any specifications

Various projects require maintaining a consistent dew point for performance and function. A dehumidifier is an ideal solution when a process or environmental factor is creating high humidity that a commercial air conditioner alone cannot eliminate. We can add a dehumidifier to an HVAC system to reduce stress on the air conditioner and help you maintain the desired dewpoint in a space that would be too humid without it.

When selecting an HVAC dehumidifier for your space, there are various considerations, including the position and configuration of the dehumidifier, BMS integration, airflow, and custom options to enhance performance. At DCA, we specialize in mechanical dehumidifiers for commercial HVAC applications. Our specialists have the knowledge and experience to help you find a solution that suits your needs.

Selecting the Best Commercial Dehumidifier for Your Needs

High humidity poses a serious problem for many facilities. Not only does excess moisture make occupants uncomfortable, but it can render a room less safe, encouraging mold growth and interfering with electrical devices. Similarly, in a warehouse or factory setting, uncontrolled humidity can damage products or even interrupt processing.

Maintaining a relatively dry atmosphere is essential to preventing these outcomes. However, residential dehumidifiers are not powerful enough for large spaces or high-volume requirements. Instead, facilities can turn to commercial dehumidifiers, which can remove anywhere from a few pounds to several hundred pounds of water each day. These systems make it simple to regulate air quality specifications, no matter the size of the space.

Commercial dehumidifiers can be split into two groups based on their mechanism of action. Desiccant units use materials like silica gel to extract moisture, while mechanical ones rely on refrigeration to condense water and remove it from the air. At DCA, we specialize in powerful mechanical dehumidifiers that perform well in diverse environments. These systems ensure consistent ventilation and optimal moisture management to keep interiors healthy and comfortable.

Where To Use a Commercial Dehumidifier?

Mechanical dehumidifiers are best suited for environments with dew points over 50° F and temperatures between 60° and 90° F. This range makes them effective for many types of buildings, ranging from fitness centers to factories. They work well for even high-volume needs and can help facilities comply with strict health and safety regulations.

Some of the many applications of commercial dehumidifiers include, but are not limited to:

  • Indoor swimming pool rooms of any size
  • Therapeutic pools, whirlpools, spas, and hydrotherapy centers
  • Hotels, motels, fitness centers, gyms, and retirement homes
  • Retirement homes, residential care homes, hospitals, schools and universities
  • Processing and blendings facilities where hygroscopic material are being used
  • Wastewater and freshwater management facilities
  • Climate and humidity controlled warehousing
  • Grow rooms, aquaculture, and vertical farming
  • Machining and grinding operations where water-based coolant is used to cool tooling
  • Custom applications where a desired specific dew point is critical
  • High moisture load applications housed in small volume spaces
  • 100% outdoor air applications

Many other applications are possible, and custom units are available to accommodate unique demands.
