DanVex DEH-K Series — Industrial Stationary Dehumidifiers, 200–1000 L/day
Stationary industrial dehumidifiers from 200 to 1000 L/day for manufacturing, large warehouses, food and pharmaceutical production, plant cultivation, and logistics centres. Full Inverter, E-Coating, top-discharge airflow, BMS-ready.
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 cultivation facilities, and infrastructure environments where humidity threatens equipment.
The four model designations cover dehumidification capacities from 200 to 1000 litres per day. The DEH-3K, DEH-5K, and DEH-10K share a full premium specification — Inverter compressor, E-Coating-protected heat exchanger, 5-in-1 air quality sensor, UV sterilisation lamp, anion generator, Wi-Fi + Modbus RTU RS-485 connectivity, Hot Gas Defrost, and three-phase 380–415 V power. The DEH-2K is offered in two configurations differentiated by electrical supply: a three-phase 380–415 V version, and a single-phase 220–230 V version — both detailed in the Models section below.
Every DEH-K unit is built around vertical top-discharge airflow: air is drawn through the front filter panel and discharged upward through the cabinet top. This format eliminates short-circuit recirculation in the unit’s own air, distributes dry air toward the upper room volume where moisture accumulates by convection, and connects directly to overhead ductwork without additional plenums. All models use R-32 refrigerant and meet IPX4 ingress protection.

Coverage figures are indicative for typical industrial conditions (medium humidity load, ceilings around 4–6 m, normal air-change rates). Actual sizing depends on initial RH, target RH, ceiling height, infiltration, process moisture sources, and whether the unit operates standalone or via ductwork. For food production with active wet cycles, plant cultivation rooms with active transpiration, or large open spans, contact us for project-specific sizing — high-capacity selection benefits from a moisture load calculation rather than a rule-of-thumb.

Where Is the DEH-K Series Used?
Stationary industrial dehumidifiers are designed for permanent installation in spaces where moisture control is a continuous requirement — not a temporary fix. Typical environments:
Application Guide
| Application | Why DEH-K is the right fit | Recommended model |
|---|---|---|
| Food production — meat and cured meats, cheese, confectionery, spices, fish drying | Curing chambers for cured meats, cheese maturation rooms, confectionery production, spice processing, and fish drying all require precise RH held within narrow bands — humidity drift directly affects product quality, shelf life, and weight loss profiles. Full Inverter modulation holds RH steady where fixed-speed equipment overshoots. E-Coating resists organic acids, brines, and chlorinated cleaning agents typical of food processing. UV sterilisation and anion generator reduce airborne microbial load between cleaning cycles. | DEH-3K / DEH-5K typical DEH-10K for large facilities |
| Pharmaceutical production & cleanroom support | Pharmaceutical processes are sensitive to humidity drift — tablet hardness, capsule integrity, powder hygroscopic behaviour, and active-ingredient stability all depend on stable RH. Full Inverter holds setpoint without cycling spikes. Modbus RTU RS-485 integrates with BMS and validated facility monitoring. UV + ion + 5-in-1 sensor support strict hygiene protocols. Solvent-free electrochemical E-Coating is suitable for environments with stringent material-contact restrictions. | DEH-3K / DEH-5K typical DEH-10K for facility-wide |
| Manufacturing — furniture, paint shops, electronics, printing | Furniture and woodworking (timber stability), paint shops (paint adhesion and curing), electronics assembly (PCB moisture, ESD-related humidity windows), and printing/typography (paper dimensional stability, ink behaviour) all rely on controlled humidity. Top-discharge airflow distributes dry air toward high ceilings; Full Inverter handles cyclical loads from production schedules without short-cycling. | DEH-3K / DEH-5K per zone DEH-10K for whole-hall |
| Large warehouses & logistics centres | Seasonal humidity in warehouses 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 duct distribution to multi-zone facilities, including class A logistics centres. Permanent installation on Modbus RTU RS-485 integrates with site facility management systems. | DEH-2K / DEH-3K for moderate loads DEH-5K / DEH-10K for large halls |
| Plant cultivation & medicinal cannabis facilities | Indoor cultivation of vegetables, herbs, ornamentals, and licensed medicinal cannabis requires tight humidity control across vegetative, flowering, and drying phases — humidity targets shift by stage, and excursions cause mould (botrytis), powdery mildew, and yield loss. Active plant transpiration adds significant moisture load (often 1–2 L per plant per day at flowering). Full Inverter modulates against the plant load curve; UV sterilisation and anion generator reduce airborne pathogen load; Modbus RTU RS-485 integrates with cultivation control systems. Top-discharge airflow distributes dry air above the canopy without disturbing plants. | DEH-3K per grow room DEH-5K / DEH-10K for commercial facilities |
| Infrastructure — pumping stations, water utilities, server rooms, electrical switchgear | Pumping stations, water treatment facilities, telecommunications shelters, server rooms, and electrical switchgear rooms all suffer condensation on cold equipment surfaces. Condensation causes corrosion, insulation breakdown, and short-circuit risk. Permanent stationary dehumidification on Modbus RTU RS-485 integrates with site SCADA. The DEH-2K is a cost-effective solution for infrastructure spaces; upper models cover larger plant rooms and multi-cabinet halls. | DEH-2K / DEH-3K typical |
Why Top-Discharge Airflow Matters
Most condensation-type dehumidifiers on the industrial market discharge air horizontally — either out the front or out the side — because that is the simplest layout. In an industrial space with high ceilings, this creates two problems.
First, dehumidified air discharged at floor level immediately falls back toward the unit’s intake (it is colder and denser than room air after passing through the evaporator). This causes the dehumidifier to recirculate its own dry air without affecting the room as a whole — the so-called short-circuit effect. Capacity numbers drop, room RH stays high.
Second, water vapour is lighter than dry air. Moisture rises and accumulates near the ceiling by natural convection — often visible as condensation on overhead pipework, structural steel, or exposed rafters. A horizontal-discharge dehumidifier never reaches that air mass.
The DEH-K Series uses vertical top-discharge: dry air is pushed upward through the cabinet top, mixes with the upper room volume where moisture concentrates, and the resulting circulation carries it back down through the front intake at floor level. The unit dehumidifies the whole room volume, not just the air immediately around it. Top-discharge also connects directly to overhead ductwork without additional plenums, which is the practical reason it is the standard format for commercial and industrial installations.
How Does DEH-K Compare to the Market?
The European market for high-capacity stationary dehumidifiers spans three tiers: industrial-grade equipment from major specialist manufacturers (full feature set, premium price), mid-range commercial-industrial units (selected features, mainstream price), and entry-level commercial dehumidifiers (basic feature set). The table below positions the DEH-K Series — specifically the Full Inverter models DEH-3K, DEH-5K, and DEH-10K — against typical mid-range and entry-level specifications in the industrial segment.
About this comparison: ‘Mid-range market industrial dehumidifier’ refers to typical specifications of stationary commercial-industrial dehumidifiers in the mid-price segment from established European manufacturers. ‘Entry-level’ refers to the lower price segment. Feature availability is based on currently published specifications.

Key Technologies — at a Glance
- Inverter compressor (DEH-3K / 5K / 10K and DEH-2K Inverter) — varies speed continuously to match real demand; up to 40% energy saving vs fixed-speed, no humidity spikes, longer compressor life
- E-Coating on the heat exchanger — electrochemical anti-corrosion layer; resists organic acids, chlorinated cleaning agents, salt vapours, brines, and aggressive industrial atmospheres
- Top-discharge airflow — vertical dry-air discharge eliminates short-circuit recirculation, reaches the upper room volume where moisture concentrates, and connects directly to overhead ductwork
- High-pressure centrifugal blower — two motor implementations: Smart-Inverter EC System (high-efficiency EC motor, variable 0–100%, soft start) on the DEH-2K Inverter, DEH-3K, DEH-5K, and DEH-10K; Step-Control AC (heavy-duty AC motor, multi-speed Low/Med/High) on the DEH-2K.
- 5-in-1 air quality sensor — CO₂, PM2.5, TVOC, relative humidity, and temperature monitored continuously; readings available locally and via Wi-Fi/Modbus. Built-in monitoring eliminates the need for external hygrostats, transducers, and BMS air-quality sensors — reducing installation cost and integration complexity
- Built-in temperature and humidity sensors with automatic setpoint control — standard on every model; the unit holds humidity to the set value automatically, no external hygrostats or controllers required for typical installation
- Pre-Configured for installation — every unit ships ready for connection with built-in sensors, digital controller, 5-in-1 air sensor, UV + Anion modules, G4 filter, Antifungus treatment, and pre-charged R-32 refrigerant. Final commissioning is limited to electrical connection (by certified electrician) and condensate drain — no separate purchases of sensors, hygrostats, or accessory modules required
- UV sterilisation lamp + Anion Generator — standard on all models; reduces airborne bacteria, mould spores, and pathogens without additional chemical dosing
- Hot Gas Defrost — 3-minute defrost cycle. Operation maintained from +5°C
- Antifungus internal treatment — cabinet interior is treated to suppress mould and bacterial growth, supporting hygiene-sensitive applications
- Tool-free G4 filter access — filter is removable from the front panel without dismantling the cabinet, washable, and replaceable in seconds; reduces maintenance downtime in dusty industrial environments where filter loading is rapid
- Wi-Fi + Modbus RTU RS-485 — both protocols active simultaneously on every model; remote app control alongside BMS/SCADA integration. Centralised monitoring of multiple units across a facility means one facility manager sees all dehumidifier status from a single screen, without physical inspection rounds — direct labour cost reduction in multi-unit installations
- Three-phase 380–415 V power on most models; 220–230 V single-phase available on DEH-2K Inverter for sites without three-phase supply
