Capable of heavy-duty operation, this machine comes with several great features that ensure that you have no humidity problems once you’ve employed it.

Before you set your heart on it, however, have a look at the features that this dehumidifier offers. 

Special Features : Compact Design, Energy Star certification, Auto- Operation, Heavy-duty condensate pump, Optional Remote Control, Automatic Defrost, Memory Restart, and more. 

Sentinel HDi90 has a well-constructed, compact design, and it is smaller than many other basement models with similar specifications. The compact design (23.2″ (W) x 15.2″ (D) x 17.7″ (H)) and adjustable feet allow users ease of transportation, placement, and storage when not in use. The dehumidifier can effectively cover up to 2600 Sq. Ft. and has a functioning range between 35-90% (Humidity) and 35- 104 degree Fahrenheit (Temperature). 

The model is easy to work with, and thanks to its automatic functioning, you don’t have to worry about a whole lot. Its smart functioning cuts the operating and maintenance time by a lot, and you can do your work without worrying about how everything’s going with your Sentinel HDi90. 

  • The unit turns on and off automatically, and there’s a minimal sound disturbance (Sound Pressure Level: <58 dB(A)). 
  • Users can use the optional remote monitoring system for convenience and control the dehumidifier from afar. It is a helpful feature for hectic workdays. 
  • The machine has a Memory Restart option. In case there’s a power outage, the unit automatically restarts and retains the settings from the previous session. 

Sentinel HDi90 is a breeze to manage

The unit can quickly and effectively remove a lot of moisture. It can remove up to 90 Pints per day in AHAM conditions and around 190 Pints on saturation, making it fit for heavy-duty applications. Sentinel HDi90 is Energy Star Certified product(verified by Underwriters Laboratories on 2020-1-1) and is an efficient dehumidifier. It effectively removes an impressive amount, consuming less energy than conventional dehumidifiers, improving your energy saving (save approx. $250 per year).

There’s also a heavy-duty condensate pump, which makes continuous removal of moisture possible. The unit can continue to function, and there’s no need to stop occasionally to empty the condensate. The pump takes care of that, and the dehumidifier can operate smoothly and efficiently. 

Sentinel HDi90 is a safe option as well

  • The unit is fully compliant with the electrical safety ETL. 
  • To solve the freon leakage problem, a concern in many dehumidifiers, Alorair has introduced a Rare earth alloy tube evaporator. It safeguards the coils and extends their work lives by maintaining the coil’s heat transferability. 
  • Sentinel HDi90 features the MERV-1 Filter that safeguards the internal components from dust or any other harmful particles, ensuring durability. The Filter can be washed every 2-3 months and replaced timely to maintain its effectiveness. 

The unit also has the automatic- defrost option for user convenience. Thanks to the quick and efficient defrosting process, low- temperatures (36 degrees Fahrenheit) operation becomes possible. Whenever the unit detects frost on the coil, it initiates the defrost cycle and prevents the formation. 

What this means is, you don’t have to stop the unit now and then to defrost. Instead, the dehumidifier takes care of the process automatically, making the unit work continuously and efficiently.
