Industrial dehumidifiers

The industrial dehumidifier is essential equipment for controlling excessive humidity in professional environments. At Climatik, we support construction, industrial, agricultural, and post-disaster restoration professionals in selecting dehumidification systems adapted to the constraints of construction sites, warehouses, workshops, and industrial buildings.

Our range includes industrial dehumidifiers from 20 to 400 liters per day, equipped with condensation or desiccant technologies depending on the operating conditions. These professional pieces of equipment maintain optimal humidity levels between 40 and 60%, protecting structures, equipment, and goods from humidity-related damage.

Professional dehumidification technologies

Condensation dehumidifiers are the most common solution for temperate environments (15-35°C). A compressor cools an evaporator where air humidity condenses; the collected water is drained by gravity or a lift pump. Extraction capacity ranges from 20 to 150 liters per day depending on the model, with electrical consumption from 300 to 1,500 watts. Maximum efficiency between 15 and 30°C with humidity >50%.
Desiccant dehumidifiers use an absorbent rotor (silica gel) that captures moisture, then continuously regenerates with hot air. This technology works effectively at low temperatures (down to -10°C) and low humidity (<40%), conditions where condensation becomes ineffective. Capacity ranges from 30 to 400 liters per day, with power consumption from 600 to 3,000 watts. Essential for winter construction sites, cold rooms, and unheated areas.

The choice between the two technologies strictly depends on operating conditions: ambient temperature, initial humidity level, and desired performance. A condensation dehumidifier is ample for 80% of temperate professional applications. Desiccation is only necessary for extreme conditions (cold, very low target humidity).

Industrial vs. domestic dehumidifiers

Industrial dehumidifiers are distinguished by their robustness, high extraction capacity, and continuous operation 24/7 for several weeks or months. They feature reinforced metal construction, professional rotary compressors, high-pressure centrifugal fans, and adjustable air ducts. Capacity ranges from 30 to 400 L/day for volumes from 100 to 2,000 m³.

Domestic models extract 10 to 25 L/day maximum, have plastic construction, and operate 8 to 12 hours daily. They are unsuitable for construction sites and professional environments: rapid overheating in continuous use, insufficient capacity for large volumes, and no ducts for targeted extraction.

Industrial dehumidifiers also integrate professional functionalities: precise digital humidistats (±2%), hourly programming, automatic full tank shut-off, integrated lift pump for automatic drainage, robust wheeled chassis, and ergonomic handles. Some models offer Ø100-200 mm duct connections for targeted extraction or insufflation into adjacent rooms.

Professional applications

The construction sector extensively uses dehumidifiers for drying new constructions (concrete slabs, screeds, renders), drying after water damage, and facilitating painting and coating work by eliminating residual moisture. Accelerated drying helps meet delivery deadlines and allows trades to follow one another without waiting for natural drying.
Industry and logistics protect corrosion-sensitive equipment, preserve stored goods (paper, cardboard, textiles, electronics), and maintain optimal conditions for certain manufacturing processes. Refrigerated warehouses use desiccation to prevent frost and maintain controlled humidity despite low temperatures.
Agriculture dries livestock buildings to limit bacterial development and improve animal comfort, dries stored grains and forages, and maintains optimal conditions in greenhouses and mushroom farms. Humidity control reduces fungal diseases and improves yields.
Post-disaster restoration is a critical application: intensive dehumidification after flooding, water damage, or major infiltration. Drying professionals install several high-capacity units (80-150 L/day) to quickly remove water absorbed in walls, floors, and ceilings, preventing mold development and structural damage.

Sizing and selection

Sizing an industrial dehumidifier requires calculating the volume to be treated and assessing the initial humidity level. The approximate rule: for a room of 200 m² × 3 m high = 600 m³, with moderate humidity (70-80%), a dehumidifier of 50 to 80 liters per day is sufficient. For very high humidity (>80%) or rapid drying after a disaster, double the capacity: 100 to 150 L/day.

Aggravating factors require an increase: significant air renewal (frequently open doors), continuous humidity input (industrial processes, washing), low temperature (<15°C), presence of porous materials saturated with water (plaster, wood). In these conditions, prefer an oversized model by 30-50% to ensure efficiency.

For temporary installations (construction site, disaster), choose mobile models on wheels with an integrated tank. For permanent installations (warehouse, workshop), select models with continuous drainage via a hose and automated operation via a humidistat.

Questions about Industrial dehumidifiers?

Our experts answer your questions.

What is the difference between a desiccant dehumidifier and a condenser dehumidifier?

The distinction is based on the physical principle and operating conditions.

Condensation dehumidifier: A compressor cools an evaporator to about 5-10°C. Humid air passes over this cold evaporator, and the moisture condenses into droplets that drain into a tank or drain. Maximum efficiency between 15 and 35°C with humidity >50%. Capacity 20-150 L/day, consumption 300-1,500W. Quiet models (45-55 dB), low maintenance, affordable purchase cost (€500-€3,000). Covers 80% of standard professional needs.

Desiccant dehumidifier: A silica gel absorption rotor captures moisture through chemical adsorption. The rotor rotates slowly, part of it is continuously regenerated by hot air (120-140°C), and the moisture is expelled to the outside. Works efficiently down to -10°C and extracts moisture even at <30% humidity. Capacity 30-400 L/day, consumption 600-3,000W. Louder (60-70 dB), higher investment (€2,000-€8,000).

Selection criterion: Temperate site >15°C = condensation is sufficient. Winter site, cold room, or need to reach <35% humidity = desiccation is mandatory.

What dehumidifier capacity for my professional volume?

Sizing depends on volume, humidity level, and drying urgency.

Basic rule: 1 liter extracted per day for 10-12 m³ of volume under standard conditions. A 400 m² × 3 m = 1,200 m³ space requires a 100-120 L/day dehumidifier. For rapid drying (damage, urgent construction site), double the capacity: 200-240 L/day.

Practical examples: Small workshop 100 m² (300 m³) with moderate humidity 70% → 30-40 L/day is sufficient. Warehouse 500 m² (1,500 m³) humidity 75-80% → 120-150 L/day recommended. Water damage in a 150 m² house with saturated walls → 2-3 units of 80 L/day for 3-6 weeks.

Increase factors: Frequent air changes (open doors) +30%. Temperature <15°C +40%. Saturated porous materials (plaster, wood) +50%. Presence of wet processes (washing, steam) +60%.

Multiple units: above 1,000 m³, prioritize several medium-sized dehumidifiers (60-80 L/day) strategically distributed rather than a single large unit. Better air circulation, more homogeneous drying, redundancy in case of breakdown.
