The HT 901 commercial dehumidifier is designed for the Southeast Asia market. The climate in Southeast Asia is generally tropical, characterized by high temperatures, high humidity, and significant rainfall. However, the specifics can vary by country and region. Generally, the temperature is between 25°C and 35°C year-round, and the humidity is often over 80%, especially during the rainy season. As a result, the dehumidifier is very necessary for the local living and working environment. Preair HT series dehumidifiers are perfectly working in the 5~35℃ and 10%-90%RH.



With a massive 90-liter daily extraction rate, the HT901 commercial dehumidifier efficiently removes excess moisture from the air, providing fast relief in areas where large amounts of humidity need to be managed. Based on its capacity, the HT901 is suitable for a 100-120 square meter space. The power supply of the dehumidifier is 220V/50Hz, which is suitable for use in Southeast Asia countries, Indonesia, Thailand, Vietnam, Malaysia, Philippines, Singapore, Cambodia, Laos, Myanmar. It adopts R32 refrigerant and direct drain. The net weight of the machine is 41.5kg, and the dimension is 409*427.5*826.4mm. Preair is sincerely looking for reliable retailers, dealers and bulk buyers. If you are interested in our products, please feel free to email us to discuss cooperation details.
