i Product Overview

Alorair HD55P dehumidifier showcases enhanced energy efficiency compared to its forerunner, the Sentinel HD55, all while running at a rated power of 402W. Featuring a notable 17% boost in airflow, it is tailored for areas spanning up to 1500 sq. ft., encompassing spaces like attics, bungalows, and basements.

Product Description


【Energy-Efficient Dehumidification】 ALORAIR's Energy Star Dehumidifier efficiently removes 55 pints per day under AHAM conditions and 120 pints at saturation, effectively covering areas up to 1,500 sq. ft. Suitable for diverse spaces including basements, crawl spaces, garages, large rooms, or commercial settings, it reduces moisture while consuming less energy compared to conventional models, resulting in reduced energy costs.

【Automatic Defrost】 Our advanced auto-defrosting system continuously monitors the ambient temperature using built-in sensors. When the temperature is detected to be low, the unit initiates an automatic defrost cycle to prevent frost buildup and related issues. During this process, the compressor temporarily stops while the fan continues to operate, allowing the frost to thaw. Once the defrost cycle is complete, the dehumidifier resumes normal operation. This feature conserves energy and helps extend the lifespan of the unit

【Internal Corrosion Protection】 Employing advanced technology, ALORAIR's dehumidifier minimizes corrosion and freon leakage. This innovative feature shields the coils from oxide, hydroxide, or sulfide, common culprits of corrosion and freon leakage in dehumidifiers. By preserving the coil's heat transferability, it extends the unit's lifespan and ensures consistent efficiency over time.

【Modern Home Design】 Tailored for modern homes, this dehumidifier boasts features such as an auto defrosting system, optional remote control, MERV-1 filter, and low-temperature operation. Additionally, it is C-ETL listed for safety, making it suitable for use in crawl spaces, basements, and commercial environments.

【5-Year Warranty & Safety Assurance】 ALORAIR's Sentinel HD55P dehumidifier fully complies with electrical safety standards (ETL). Each unit is backed by a 5-year warranty, and a dedicated customer support team is available to assist users at any time.

AlorAir Sentinel HD55P Crawl Space Dehumidifier

AlorAir crawlspace dehumidifiers play a crucial role in mitigating excess moisture and safeguarding your home. Opting for an ENERGY STAR-certified dehumidifier not only yields savings on energy bills but also ensures top-notch performance, features, and comfort, all while contributing to environmental preservation by curbing greenhouse gas emissions.

Alorair is dedicated to advancing its technology to improve the energy efficiency of dehumidifiers. The Sentinel HD55P exemplifies this dedication, capable of extracting up to 55 liters of moisture per day under AHAM conditions and up to 120 pints per day at full saturation. 

This dehumidifier features a GPP mode, accurately detecting the volume of moisture vapor in the air to help maintain optimal humidity levels in your surroundings. Offering both gravity and pump drainage options, it eliminates concerns about rust from standing water, ensuring practical and efficient dehumidification.
