Direct answer Lithium cells are chemically incompatible with water. Lithium reacts with moisture to form lithium hydroxide and hydrogen, and the electrolyte salt reacts to form hydrofluoric acid, so dry rooms are held at a −40 °C dew point or lower, around 1% RH at 22 °C. Only adsorption reaches that level; a refrigerant coil stops near +5 °C dew point and ices below it. −40 °CStandard dry-roo...

Direct answer A single desiccant rotor typically reaches 1–10% RH, corresponding to a dew point of about −40 °C, or roughly 0.08 g of water per kilogram of dry air. Putting two rotors in series pushes the supply dew point towards −60 to −70 °C. What you actually achieve depends on regeneration temperature, rotor speed, air sealing and how much moisture is leaking into the room. 1–10% RHSingle ...

Direct answer Below about 45–50% RH only the desiccant rotor keeps working. A condensing machine hits a physical wall: it has to cool air to reach its dew point, and once the coil approaches freezing it ices instead of draining. The rotor adsorbs water directly, so it keeps removing moisture down to 1–10% RH and to dew points of −40 °C and lower, at the cost of higher energy per kilogram remove...

Direct answer A desiccant rotor dehumidifier dries air by adsorption rather than condensation. Process air passes through a slowly rotating wheel coated with silica gel or zeolite, which holds the water vapour; a separate heated stream regenerates the wheel and carries the moisture outside. It is required when the target is below roughly 45–50% RH, when the space runs below about 5 °C, or when ...

Direct answer A split dehumidifier runs two independent control loops. The refrigeration circuit removes moisture by cooling air below its dew point, then a reheat stage restores the temperature the room actually needs. Because the reheat section is part of the same machine, the unit can dry without cooling the space, cool without over-drying, or hold temperature steady and move only the humidi...

Direct answer A split heating cooling dehumidifier is a two-part climate system: an indoor unit conditions the air and an outdoor unit rejects or absorbs heat through a refrigerant circuit. The same machine dehumidifies, heats, cools and ventilates, and it holds temperature and humidity to independent setpoints. Because the compressor sits outside, indoor noise and compressor heat stay out of t...

Direct answer For a permanent, year-round requirement a fixed installation is cheaper per litre of water removed and per square metre covered. For a temporary, seasonal or multi-site need, hand push units win on capital and flexibility. The crossover sits at roughly 18–30 months of continuous duty: shorter than that and mobile units usually cost less in total. 18–30 monthsCrossover point for f...

Direct answer A hand push dehumidifier is a self-contained condensing unit built into a wheeled trolley chassis, so one person can move it between rooms or sites without tools. Typical industrial units remove 60–360 litres per day at 30 °C / 80% RH, move 500–1,200 m³/h of air and weigh 35–160 kg. It is used wherever the moisture problem moves: construction drying, flood restoration, temporary s...

Direct answer Choose a ceiling mounted dehumidifier when at least one of three conditions is true: the floor has no spare space, the space is tall enough that dry air needs to be delivered from height, or humidity control is permanent and should be ducted into the building. If the need is temporary, the layout keeps changing, or the moisture load is very heavy, a floor standing unit remains the...

Direct answer A ceiling mounted unit saves the floor: it uses zero square metres of working area, while a floor standing machine occupies 0.35–0.7 m² plus service clearance. The trade-off is installation. Ceiling units need structure, drainage and a power feed at height; floor units plug in and can be moved. Choose ceiling when floor area is scarce or ducted distribution is needed, and floor st...

Direct answer Size a floor standing dehumidifier on real removal capacity, not the nameplate figure. Work out the moisture load from room volume, the humidity change you need and the infiltration from doors and people, then divide by 0.6–0.7 to convert that real requirement into the nameplate capacity you should buy. 0.6–0.7Real / nameplate conversion factor 1.1–1.2Safety factor on calculated...

Direct answer A floor stand dehumidifier is a self-contained, ground-mounted unit that you position wherever the moisture problem is. It is best used in warehouses, basements, logistics halls, food and textile stores, indoor pools and production areas — anywhere the space runs at normal ambient temperature, the target is 45–60% RH, and you want capacity you can move or add without building wor...

Direct answer For a 500 m² warehouse with a 4 m ceiling held at 27 °C / 60% RH, budget roughly 200–270 litres per day of real removal capacity. Because nameplate capacity is measured at 30 °C / 80% RH, that means buying nameplate capacity in the 350–450 L/day band — typically two 240 L/day units rather than one large machine. 200–270 L/dayReal capacity needed 350–450 L/dayNameplate capacity t...

Direct answer Choose a condensing dehumidifier if your warehouse stays above about 15 °C and you only need to hold 45–60% RH — it costs less to buy and roughly half as much to run. Choose a desiccant rotor dehumidifier if you need below 40% RH, if the space runs below 10 °C, or if your spec is written as a dew point rather than a relative-humidity figure. 40% RHPractical crossover point 15 °C...

Direct answer A condensing dehumidifier removes moisture by pulling room air over a refrigerated coil, cooling it below its dew point so water vapour condenses into liquid, and draining that water away. The dried air is then warmed a few degrees before it returns to the room. It is the most energy-efficient dehumidification technology whenever the space stays above roughly 15 °C and the target...

Its better not. Because if the door or windows open, the wet air will go inside room and seriously affect the dehumidifying efficiency.

Yes, there are ducts on the inlet and outlet of ceiling mounted dehumidifiers. You can connect them to your HVAC system.

Yes, it need to bigger quantity and tell us what kind of controlling mode or program you need?

Yes, you can. Please take off the original wire from controller panel and electrical box. And use six core shielding wire to connect on the port of PBC and controller panel. (More information please confirm with our sales department.)

The fan will still work for around 3~5 minutes to cool down the evaporate after turning off.

The dehumidifier will stop working automatically once room humidity meet the desired humidity setting on the controlling panel. So please confirm if your room humidity meet the humidity setting on controlling panel?

No, you don’t need. The refrigerant circulates inside the coil pipe and compresssor. It will not disappear or reduce if the refrigeration syste is in good condition.

Yes, please confirm us your controlling program format and connecting port.

Yes, right now we have DDP service in US to send machines to your door.
