About the DEH-K Series

The DanVex DEH-K Series is a range of stationary industrial dehumidifiers for permanent installation in spaces where humidity control is part of the building or process specification: manufacturing facilities, large warehouses and logistics centres, food and pharmaceutical production, plant-growing facilities and infrastructure environments where humidity threatens equipment.

The four models cover capacities from 240 to 1 000 litres per day and share the full premium specification: a Full Inverter compressor with a Smart-Inverter EC fan and EEV valve, an E-Coating heat exchanger, 5-in-1 sensor, UV sterilisation lamp, anion generator, Wi-Fi + Modbus RTU RS-485 connectivity and Hot Gas Defrost. The DEH-2K runs on single-phase 220–230 V — for sites without a three-phase supply; the DEH-3K, DEH-5K and DEH-10K run on three-phase 380–415 V.

Every DEH-K unit is built around a vertical top-discharge airflow: air is drawn through the front filter panel and discharged upward through the top of the cabinet. This format eliminates short-circuiting of the unit recirculating its own dry air, distributes air into the upper volume of the room where moisture accumulates by convection, and connects directly to overhead ductwork without additional plenums. All models use R-32 refrigerant with IPX4 protection.

Coverage figures are indicative for typical industrial conditions (moderate load, 4–6 m ceilings, ordinary air exchange). The actual choice depends on starting and target humidity, ceiling height, infiltration, process moisture sources and whether the unit runs standalone or ducted. For food production with active wet cycles, grow rooms with active transpiration and large open spaces — contact us for precise project selection: choosing the higher capacities benefits from a moisture-load calculation rather than a rule of thumb.

Application guide

ApplicationWhy DEH-K is the right choiceRecommended model
Food production — cured meats, cheeses, confectionery, spices, fish dryingMeat-curing chambers, cheese-ripening rooms, confectionery production, spice processing and fish drying require RH held within tight ranges — humidity drift directly affects product quality, shelf life and weight-loss profile. Full Inverter regulation holds RH stable where fixed-speed equipment overshoots. E-Coating resists organic acids, salt solutions and chlorine-laden cleaning agents. UV sterilisation with the anion generator reduces microbial load between wash-down cycles.Typically DEH-3K / DEH-5K · DEH-10K for large facilities
Pharmaceutical production and cleanroom supportPharmaceutical processes are sensitive to humidity drift — tablet hardness, capsule integrity, the hygroscopic behaviour of powders and the stability of active ingredients depend on steady RH. Full Inverter holds the set-point without cyclic jumps. Modbus RTU RS-485 integrates with BMS and validated facility monitoring. UV + anions + the 5-in-1 sensor support strict hygiene protocols. Solvent-free electrochemical E-Coating is appropriate in environments with strict material-contact restrictions.Typically DEH-3K / DEH-5K · DEH-10K at facility level
Manufacturing — furniture, paint shops, electronics, printingFurniture and joinery (wood stability), paint shops (coating adhesion and curing), electronics assembly (moisture in boards and static humidity windows), printing (paper dimensional stability and ink behaviour) — all depend on controlled humidity. Top discharge distributes dry air to high ceilings; Full Inverter handles the cyclic loads of production schedules without short cycling.DEH-3K / DEH-5K per zone · DEH-10K for the whole hall
Large warehouses and logistics centresSeasonal humidity causes condensation on packaging, cardboard collapse, label damage and corrosion of metal goods (steel, machine parts, tools). Static pressure of 200–300 Pa across the range supports ducted distribution in multi-zone facilities, including Class A logistics centres. Permanent installation on Modbus RTU RS-485 integrates with site management systems.DEH-2K / DEH-3K for moderate loads · DEH-5K / DEH-10K for large halls
Plant growing and licensed medical-cannabis facilitiesIndoor cultivation of vegetables, herbs, ornamentals and licensed medical cannabis requires tight humidity control by vegetative, flowering and drying phase — targets change with the stage, and deviations produce grey mould, powdery mildew and crop loss. Active transpiration adds a substantial moisture load (often 1–2 litres per plant per day in flowering). Full Inverter regulates to the plant load curve; UV and anions reduce airborne pathogens; Modbus integrates with grow-management systems. Top discharge distributes dry air above the canopy without disturbing the plants.DEH-3K per grow room · DEH-5K / DEH-10K for commercial facilities
Infrastructure — pumping stations, water utilities, server rooms, switchroomsPumping stations, water-treatment facilities, telecom shelters, server rooms and switchrooms suffer condensation on cold equipment surfaces — corrosion, insulation degradation, short-circuit risk. Permanent stationary dehumidification on Modbus RTU RS-485 integrates with site SCADA. The DEH-2K covers typical infrastructure rooms; the larger models — bigger equipment halls.Typically DEH-2K / DEH-3K

Why does top-discharge airflow matter?

Most condensation dehumidifiers on the industrial market discharge air horizontally — from the front or side — because it is the simplest layout. In a high-ceilinged industrial space this creates two problems.

First, dehumidified air discharged at floor level immediately sinks back toward the unit inlet (it is colder and denser than room air after passing the evaporator) — the unit recirculates its own dry air without affecting the room as a whole: short-circuiting. Capacity figures fall and humidity stays high. Second, water vapour is lighter than dry air; it rises and accumulates near the ceiling by natural convection — often showing as condensation on overhead pipes, structural steel and exposed beams. A horizontal dehumidifier never reaches that air mass.

The DEH-K Series uses vertical top discharge: dry air is driven upward through the top of the cabinet, mixes with the upper volume where moisture concentrates, and the resulting circulation carries air down through the front inlet at floor level. The unit dries the whole room volume, not just the air around it. Top discharge also connects directly to overhead ductwork without plenums — the practical reason it is the standard format for commercial and industrial installations.

How does DEH-K compare with the market?

The European market for high-capacity stationary dehumidifiers has three tiers: industrial equipment from the large specialist companies (full features, premium price), mid-range commercial-industrial units (selected features) and budget commercial units (basic features). The table positions the series against the typical specifications of the mid-range and budget tiers.

About this comparison: "mid-range" refers to the typical specification of commercial-industrial stationary dehumidifiers in the mid price segment on the European market; "entry-level" — to budget commercial units. The comparison is indicative by feature category, not a claim about any specific manufacturer.

Frequently asked questions

How is a stationary industrial dehumidifier sized for a factory or large warehouse?
Industrial selection rests on a moisture-load calculation, not on an approximate area figure. The inputs: space volume (not floor area alone — ceiling height matters), starting and target humidity, infiltration rate (air changes from doors, ventilation and gaps), process moisture sources (wet processes, cleaning cycles, occupancy load, plant transpiration) and outdoor humidity at design conditions. As a practical starting point: 1 L/day of capacity per ~1.5–2 m² of floor area for typical industrial conditions with 4–6 m ceilings. On that basis the DEH-K Series covers from ~150 m² (DEH-2K) to ~1500 m² (DEH-10K) in typical conditions. For food production with active wet cycles, grow rooms and spaces with high outdoor-air infiltration the requirements are higher. Contact us for a precise calculation for your project.
What is the difference between Full Inverter and fixed-speed industrial dehumidifiers?
A fixed-speed compressor runs at full power until the target humidity is reached and then stops — humidity jumps between cycles, peak consumption at every start and accelerated mechanical wear. A Full Inverter compressor continuously varies its speed to the actual moisture load: low power near the set-point and higher only when needed. The result: up to 40% lower consumption, no humidity drift, less noise and a far longer compressor life. For continuously operating facilities the inverter price difference usually pays for itself within the first seasons on electricity savings alone. In the DEH-K range every model comes with a Full Inverter compressor as standard — from the single-phase DEH-2K to the DEH-10K.
Why does top-discharge airflow matter in industrial applications?
Two physical effects undermine the performance of horizontal-discharge dehumidifiers in high-ceilinged industrial spaces. First, dry air leaving the dehumidifier is colder and denser than room air, so it sinks and is drawn back into the unit — short-circuiting the dehumidification cycle. Second, water vapour is lighter than dry air and accumulates near the ceiling by natural convection — where horizontal units do not reach, and where condensation often appears on overhead pipes and steel structures. Top-Discharge drives dry air upward into the humid upper volume, drives full room circulation, and the same outlet connects directly to overhead ductwork without an extra plenum. It is the standard format for industrial and commercial installations with ceilings above 3–4 m.
Can a stationary industrial dehumidifier be connected to ductwork?
Yes. Stationary dehumidifiers with sufficient static pressure are connected to ductwork to distribute dry air to several zones or specific delivery points. Static pressure determines the maximum duct length and number of connections the unit can handle: in the DEH-K Series the DEH-2K and DEH-3K provide 200 Pa, the DEH-5K 250 Pa and the DEH-10K 300 Pa for long runs or central-HVAC integration. Top discharge makes the duct connection direct — the outlet on top of the cabinet is ready for a vertical duct. Filter access remains from the front panel, so the unit can be installed against a wall.
Does a high-capacity industrial dehumidifier require three-phase supply?
Most high-capacity industrial dehumidifiers require three-phase 380–415 V. The reasons are practical: the peak power of the larger compressor (up to 21 kW on the DEH-10K) exceeds what a single-phase circuit can reasonably deliver; three-phase reduces motor torque pulsation and per-phase current; and most industrial buildings are already equipped with it. The DEH-3K, DEH-5K and DEH-10K run on 380–415 V. For sites without a three-phase supply, the DEH-2K runs on 220–230 V single-phase and delivers up to ~240 L/day with the same full feature set. Below this class the mobile DanVex DEH-i Series covers up to 180 L/day on standard single-phase.
How loud is a stationary industrial dehumidifier?
Modern industrial dehumidifiers produce noise from two sources: the compressor and the fan. Full Inverter compressors are quieter than their fixed-speed equivalents because they avoid start/stop transients. In the DEH-K Series the DEH-3K runs at 36–42 dB(A), the DEH-5K at 38–45 dB(A) and the DEH-10K at 40–47 dB(A) at one metre — the variable range corresponds to inverter modulation between low and full load. For comparison: normal conversation is around 60 dB(A) and a busy office 50–55 dB(A). All models are quiet enough for installation in occupied production areas, equipment rooms and back-of-house spaces.
What built-in air-monitoring and purification features do industrial dehumidifiers have?
Modern industrial dehumidifiers go beyond humidity control to overall air quality. The DEH-K Series includes three built-in systems as standard. The 5-in-1 sensor monitors CO₂ (ventilation adequacy), PM2.5 (fine particles — mould spores, bacterial fragments and dust), TVOC (volatile compounds from chemicals and processes), humidity and temperature — continuously, with readings via the Wi-Fi app and Modbus to the BMS. UV sterilisation lamps in the airflow path destroy bacteria, mould spores and viruses as air passes. The anion generator produces negative ions that bind particles, allergens and pathogens and settle them. Together they reduce microbial load and support hygiene protocols in food production, pharmaceutical manufacturing, plant growing and other contamination-sensitive environments.
