Construction Applications
WET BUILDING MATERIALS
As a contractor, ensuring the moisture content of building materials is one of your top priorities. If not properly managed, water will remain trapped in building materials causing serious bottle necks in the construction process.
WET STRUCTURES
Weather intrusion into the building envelop can happen on any job. This moisture must be removed as quickly as possible to prevent future damage, or mold growth.
MOISTURE CHARGE BACKS
Mold growth can occur within 48 hours. Mold requires high moisture levels which equate to about 70% RH. This is the easiest variable to control and prohibit mold growth. Phoenix dehumidifiers and humidity monitoring systems can provide you with proof that the building environment was kept below the conditions needed to support mold growth.
COLD/DAMP WORK ENVIRONMENTS
Increase employee productivity and morale by controlling the temperature and humidity in the work environment. This can be done while you are also controlling the environment to protect against defects. Desiccant dehumidifiers work in colder temperatures when traditional refrigerant units won’t work. This can help eliminate damp work environments.
Recommended Equipment
ADHESIVE WARRANTIES
The warranty provided by the manufacturers of adhesives typically include specific information about the need to control the moisture content of the floor during the installation of their product. You can eliminate charge-backs due to adhesive failures causing delamination and buckling. Moisture is a byproduct of the construction process. The average new 2000 square foot home contains, on average, five tons of moisture that must evaporate from the structure.
CUPPING AND GAPPING OF HARDWOOD FLOORS
Wood is a hygroscopic material. It responds to humidity levels by expanding and contracting. Wood should be allowed to acclimate to the environment it will be installed in. Wood should be installed in an environment that is kept between 40% and 60% RH. Failure to control the humidity or moisture content while installing hardwoods can result in charge-backs due to cupping and gapping.
PAINT AND DRYWALL PRODUCTIVITY
Paint and drywall drying times can be dramatically reduced by controlling the temperature and humidity level during the construction process. Good joint compound drying can occur in as little as 2 hours. In extreme conditions, it can take two or more days. Paint drying is affected in a similar manner. Ensure there isn’t lost time between coats and finishing.
WET CONCRETE
Surface prep and coating application demand very low dew point air to do the job properly. Phoenix has a full line of desiccant dehumidifiers that are designed to provide very low relative humidity levels which refrigerant dehumidifiers cannot reach.

Recommended Equipment
LEAD/ASBESTOS/MOLD
Recent legislation requires HEPA air scrubbers for asbestos removal and HEPA filtration during lead abatement on all houses built before 1978. “Ventilation of the regulated area to move contaminated air away from the employee’s breathing zone to a filtration or collection device equipped with a HEPA filter.”
HEPA/NEGATIVE AIR REQUIRED
When working on an existing structure such as a hospital, there may be the need for HEPA filtered air and/or a contained work space. Phoenix HEPA air scrubbers and other ductable climate control equipment allow you to finish the job while keeping occupants safe from airborne dust particles.
