Always know your laundry room is safe and efficient. The LintAlert® connects via Wi-Fi and monitors the dryer exhaust system for problems. As lint naturally builds up over time, LED indicators progressively illuminate to show how efficiently your dryer is operating. When restriction becomes dangerous, an alarm is triggered. While it may be obvious that maintaining an efficient exhaust system can save money on utility bills, it’s important to know that airflow restriction can create a very real fire hazard.
Clean and efficient dryer ducts improve cycle times and reduce utility costs. By monitoring the dryer’s performance, you can maximize efficiency and know when additional service is needed.
With the LintAlert, you’ll know when your laundry is done, how much energy you are saving, and you’ll get alerts before problems become a danger.
Airflow Restriction Causes Dryer Fires
While it may be obvious that dryer exhaust problems will increase your utility bills, it’s important to know they also create a very real fire hazard. The U.S. Fire Administration reports more than 15,000 dryer fires every year. Today, you can protect your home and family from that threat.
Detect Laundry Room Flooding
Your Wi-Fi enabled LintAlert PRO Plus can double as a leak detector to mitigate the risks and damages associated with washing machine floods. The Leak Sensor is a valuable add-on that simply plugs into the bottom of the LintAlert and gets placed near the washing machine. As soon as moisture is detected, an alarm will sound. With this important warning, immediate action can be taken to prevent property damage, long cleanup times, and large insurance claims.
How Does it Work?
Back pressure in the dryer’s exhaust system is always changing. Over time, it increases because of lint buildup, crushed hoses, damaged vent hoods and—surprisingly often—animal nests. The LintAlert® works to protect you by continually monitoring airflow and showing the exact pressure in the exhaust system. Armed with this information, you can save energy and be certain the dryer is operating at safe levels.
Air Pressure Sensor
The LintAlert gathers this information through a highly discriminating digital pressure sensor. It detects extremely small changes in water column inch (WCI) pressure by sampling minute amounts of airflow. Because of the very small volume of air sampled, there is zero impact to air pressure in the duct.
The air pressure samples are then analyzed by a programmable integrated circuit. This small onboard computer evaluates data to know whether the dryer is on and how the exhaust system is performing. Most importantly, it learns each unique system (click here to learn more about computer calibration) so it can compare current airflow to optimal, then report changes over time.
These changes are shown through a simple to understand LED interface where green indicators, turn to yellow, and then red as pressure becomes more problematic.
Optimal performance is shown with a single green indicator glowing. As airflow naturally becomes restricted over time, the second, then third green indicator will illuminate. This is a good time to clean the dryer and duct system for best energy efficiency and safety. In the event the system is not cleaned at that point, the yellow and red indicators will eventually illuminate. Once pressure becomes dangerous (or there is a sudden obstruction) all LEDs flash in unison and an audio alarm sounds.
Dryer Duct Connection
For the sensor to sample pressure in the system, a self-tapping fitting, the SmartTap™, attaches to the transition hose behind the dryer. This fitting is connected to the alarm module by a 1/8″ tube and provides flexibility to plug the alarm module into the nearest power outlet (to conserve available power sources, the LintAlert includes a pass through terminal into which other electronic devices can be plugged).
