Commercial dehumidifiers are mainly divided into condenser type (compressor type), low-temperature condenser type (LGR), and desiccant type. Condenser type is suitable for general warm environments, while desiccant type is suitable for low-temperature or special applications (such as pharmaceuticals, food production, etc.).

Dehumidification capacity is the primary consideration, usually measured by the amount of water (liters) that can be removed per day.Choose the appropriate dehumidification capacity based on the size and humidity of the space. For example, large spaces or high-humidity environments (such as coastal areas) require models with higher dehumidification capacities.Based on a 3-meter ceiling height and a target relative humidity of 60% , the following suggestions are provided for each type of space:space sizeArea (m²)Volume range (m³)Recommended dehumidification capacity (L/day)small space50 - 100150 - 30040 - 80medium-sized space100 - 200300 - 60080 - 170large space200 - 300600 - 900170 - 260Tip:If the environment is well-sealed or has few moisture sources, the requirement can be slightly reduced; conversely, if there are obvious moisture sources and many ventilation openings, it is recommended to choose a value close to or higher than the upper limit listed in the table.Pay attention to the water tank capacity and drainage method; for larger spaces, a continuous drainage design is more convenient.

因為「換氣次數」不同。 辦公室或商舖人流多、門窗頻繁開啟，濕氣會不斷補充進來。商業空間建議選擇比實際面積「大一級」的規格，以應付高流動性的濕氣負荷。

有。 抽濕機處理的是「空氣體積」而非平面面積。如果你的單位是高樓底（超過 3 米）或工廈空間，計算面積後應額外增加 20-30% 的抽濕量需求。

在18°C 至 30°C 之間，抽濕效果最好。 壓縮式原理是利用冷凝排水，如果環境太冷（低於 15°C），內部容易結霜，抽濕效能會明顯下降。 在低溫（5°C - 15°C）環境下，具備LGR技術的壓縮型抽濕機，表現比一般壓縮型抽濕機效果會更穩定。 如果是針對酒窖或低溫倉庫，則需要具備「自動除霜」功能的專業機型。

Many commercial dehumidifiers now come equipped with features such as automatic humidity control, timer switching, and air filtration. Automatic humidity control can automatically start or stop the machine according to settings, improving energy efficiency and ease of operation.

There are two common types: water tank type and drain pipe type. The water tank type requires periodic emptying and is suitable for short-term or manual occasions; the drain pipe type can drain automatically and is suitable for commercial environments that require long-term operation or where it is inconvenient to empty the water frequently.

If you need to move the machine frequently, it is recommended to choose a model with casters or handles for easy and flexible movement to different areas.

我們不建議抽濕機在無人看管地長時間連續運行（例如: 數天不關機），因為長時間運轉時，進氣口濾網與內部冷凝器會積聚塵埃與雜物。若風道受阻，馬達及壓縮機會持續處於高溫狀態。

The XPOWER and TX-5 dehumidifiers do not have a "timed on" function, but they can be set to "timed off".The XPOWER XD-125L model can be set to automatically shut down after a preset number of hours (the setting range is 1–23 hours).After startup, the TX-5 can be set to run for a set time and will automatically shut down after the preset number of hours (the setting range is 1–24 hours).In addition, the XPOWER and TX-5 dehumidifiers do not support external socket-type timers. These timers are suitable for appliances that use mechanical power switches (such as traditional knob fans) and can automatically start when the power is restored.Because the XPOWER and TX-5 dehumidifiers are designed with electronic button controls, they need to be restarted by pressing the button after being turned off. Therefore, even if the timer is turned back on, the dehumidifier will not run automatically.

Regular maintenance and cleaning can maintain the dehumidifier's operating efficiency, reduce energy consumption, extend the machine's lifespan, and prevent the growth of mold and bacteria, ensuring indoor air quality.If used frequently, it is recommended to clean it every three weeks to one month, especially during the humid spring and summer seasons.After removing the filter, use a vacuum cleaner or soft brush to remove dust. For stubborn dirt, rinse with water, let it air dry, and then reinstall it. Keeping the filter clean can improve dehumidification efficiency and air quality.Regularly clean the dust from the condenser and evaporator surfaces with a soft brush or vacuum cleaner. In severe cases, use a specialized cleaning agent. Be gentle when cleaning to avoid damaging the parts.When not in use, unplug the power cord and cover the dehumidifier with a dust cover to prevent dust accumulation and exposure to sun and rain.
