Crawl Space System of Products
ATMOX delivers a system of products that combines controls, sensors, circulating fans, intake/exhaust fans and dehumidifiers to provide a long-term approach to mitigating moisture while optimizing air quality in a home’s crawl space.
Crawl Space Control Center
The ATMOX control center is the “brain” of your crawl space system, continuously measuring humidity and temperature from inside and outside sensors. It efficiently manages operations to reduce moisture, improve conditions, and provides real-time status updates and alerts.
- Manages moisture in the crawl space with technology
- Measures temperature and humidity to determine most efficient operation
- Provides information on conditions in crawl space
ATMOX ACE 2.0 Crawl Space Control Set
The ATMOX ACE 2.0 Control Set is the intelligent crawl space moisture control system directing operation of components through dehumidification, ventilation, and circulation. The controller uses temperature and humidity sensors both inside the crawl space and outside to determine the best operation to improve conditions in the crawl space.
Ventilation Products
Exhaust fans and intake fans bring dry fresh air in and out of the crawl space when it will improve conditions. The control center directs this operation based on dew point calculations and comparisons.
- Improve conditions with intake and exhaust fans only when outside air is beneficial
- Use dew point comparison for effective moisture control
- Dispel odors, toxins and material off-gasses to improve air quality
- Decrease energy consumption by reducing use of dehumidifier
ATMOX Exhaust Fan – Multi-Mount with Louver – 225 CFM – Crawl Space
The ATMOX 225 CFM Exhaust Fan with Louver is used for ventilation of the crawl space. Under the direction of the ATMOX crawl space controller, this exhaust fan will operate when outside conditions and an exchange of air are beneficial to the crawl space.
ATMOX Intake Fan – Multi-Mount with Louver – 225CFM
The ATMOX 225 CFM Intake Fan with Louver is used for ventilation of the crawl space. Under the direction of the ATMOX crawl space controller, this intake fan will operate when outside conditions and an exchange of air are beneficial to the crawl space.
Circulation Products
Internal joist-mounted fans circulate air evenly throughout the crawl space, ensuring airflow reaches areas not captured by ventilation fans and extends reach of dehumidifier. The control center directs this operation based on high humidity inside crawl space and when ventilation fans are running.
- Distributes airflow and balances the drying process
- Allow dehumidifiers to function more efficiently
- Move air between tight, low or sectioned spaces
ATMOX Internal Fan – Joist Mount – 165 CFM
The ATMOX 165 CFM Joist-Mounted Internal Fan is used for circulation of air within the crawl space. Under the direction of the ATMOX crawl space controller, this internal fan will circulate air when inside humidity is elevated.
ATMOX Internal Fan – Joist Mount – 145 CFM
The ATMOX 145 CFM Joist-Mounted Internal Fan is used for circulation of air within the crawl space. Under the direction of the ATMOX crawl space controller, this internal fan will circulate air when inside humidity is elevated. These fans assist the cross flow of ventilation, extend the reach of the dehumidifier, and work to balance temperature and humidity levels within the crawl space.
Dehumidification Products
ATMOX system integrates with most major brands of dehumidifiers through the use of a relay. This external control allows for efficient operation of the dehumidifier. The control center directs the operation of the dehumidifier based on high humidity inside crawl space.
- Extend life of dehumidifier by limiting temperature operation and on/off cycling
- Use highly accurate humidity sensor separate from dehumidifier unit
- Control the use of one or more dehumidifiers
ATMOX Dehumidifier Relay
The ATMOX Dehumidifier Relay allows an ATMOX crawl space controller to control the operation of a dehumidifier.
Add-Ons
ATMOX LED String Light
The ATMOX LED String Light provides bright, energy-efficient lighting for crawl spaces or attics.
ATMOX Sensor – Wood Moisture
This ATMOX Wood Moisture Sensor works with an ATMOX controller to provide information on corresponding wood moisture content in the wood of the crawl space or attic.
ATMOX Sensor – Water Alert
The ATMOX Water Alert Sensor works with an ATMOX controller to provide a notification of a potential water issue in the location of the sensor.
ATMOX Internal Mount Solid Plates – 5 pack
The ATMOX Crawl Space Vent Cover mounts from inside the crawl space behind an opening. The covers keep air flow blocked from the outside.
