How to choose a dehumidifier: two steps

Choosing the right DanVex dehumidifier comes down to two decisions: the drying technology your environment needs, and your installation layout. Settle both and only capacity sizing remains.

1. Technology — condensation or adsorption. Ambient conditions decide the drying method:

  • Condensation (refrigerant cycle) — the efficient choice in practice from +15 °C upwards with a target above 35–40% RH; covers most pools, warehouses, production halls and occupied spaces.
  • Adsorption (desiccant) — the right choice below +15 °C or below 35% RH, where condensation loses efficiency. The AD range dries with a silica-gel rotor down to −20 °C and below 20% RH.

2. Installation — how the unit enters the building. DD, DD-F and DD-FX disappear into the building through ductwork, with DD-FX adding heating, cooling and humidification; wall/floor DEH-WP takes pool and commercial installations inside the room; mobile industrial DEH-i and stationary DEH-K cover field work and permanent duty; the compact DEH-1000P covers plug-and-play mobile tasks. Capacity runs in a continuous ladder up to 1000 L/day across these lines, and the AD adsorption range (up to 36 kg/h) covers the cold, low-humidity edge. The lines differ by technology and installation form; once a line is chosen, two or three models usually remain, decided by the required capacity. Pick the line below, then size it on its page.

Condensation capacities are measured at 30 °C / 80% RH and adsorption capacities at 20 °C / 60% RH (the industry-standard test conditions); actual capacity depends on ambient and operating conditions.

Frequently asked questions

What is the difference between condensation and adsorption dehumidifiers?
Both remove moisture, but by different physics, and each has its operating window. Condensation dehumidifiers (refrigerant cycle) — DanVex DEH-WP, DEH-1000P, DEH-i, DEH-K, DD, DD-F and DD-FX — cool air below its dew point; water condenses and drains away. They are efficient and cheapest to run at +15…+35 °C with a target above 35–40% RH; below +5 °C or below 35% RH their efficiency drops sharply. Adsorption dehumidifiers — the DanVex AD range — bind water vapour on a silica-gel rotor and work down to −20 °C with targets below 20% RH. Choose condensation for pools, warehouses, production and occupied spaces at room temperature; choose adsorption for cold storage, ice rinks, low-dew-point drying and dry pharmaceutical rooms.
How do I choose the right type of dehumidifier for my space?
Start with operating conditions and installation, not capacity. If the space is at normal temperature and needs a target of around 40–65% RH — pools, warehouses, production, museums, homes — a condensation unit is the efficient choice: DEH-WP for wall/floor installation inside the room, DEH-i for temporary or multi-site work, DEH-K for permanent industrial installation, and the ducted DD range for concealed or multi-room distribution (DD-FX adds heating, cooling and humidification). If the space is cold (below +15 °C) or needs very low humidity (below 35% RH) — cold storage, ice rinks, dry rooms — choose the AD adsorption range. Once the product line is set, size the capacity within it.
How is dehumidifier capacity measured — L/day or kg/h?
Condensation dehumidifier capacity is quoted in litres per day (L/day) at 30 °C / 80% RH — the international standard test condition that allows direct comparison between manufacturers. Adsorption dehumidifiers are usually rated in kilograms per hour (kg/h) — the same physical quantity expressed differently: one kilogram of water equals one litre, and kg/h × 24 = L/day. Actual capacity depends on ambient and operating conditions. For precise sizing in real conditions, request a project calculation rather than relying on the nameplate figure alone.
What size of dehumidifier do I need for my space?
A practical starting point for normal conditions (moderate moisture load, 4–6 m ceilings, ordinary air exchange): one litre per day of capacity for every 1.5–2 m² of floor area — a 300 m² room needs around 150–200 L/day, a 1000 m² site around 500–700 L/day. Requirements rise further for pool halls, food production with wet cycles, plant growing and high-infiltration spaces, where 2–3 times the rule may be needed. Area rules are useful for first screening only; correct sizing is driven by the total moisture load — starting and target humidity, air volume, air-change rate and moisture sources. For precise sizing, contact us with room dimensions, target, moisture sources and operating temperature.
