Industrial dehumidifiers · Two series

Industrial dehumidifiers — mobile and stationary, 59–1000 L/day

DanVex industrial dehumidifiers form a professional range in two complementary series: the mobile DEH-i (59–180 L/day, single-phase) for construction sites, water-damage restoration, food and pharmaceutical production support, plant growing, drying rooms and industrial workshops; and the stationary DEH-K (240–1000 L/day, single- and three-phase) for manufacturing facilities, large warehouses, logistics centres and infrastructure. Standard across the whole range: E-Coating, Hot Gas Defrost, a high-pressure centrifugal blower, low-GWP refrigerants (R-290 mobile, R-32 stationary) and Modbus RTU RS-485 connectivity for direct BMS integration.

About the range

Industrial dehumidification is a technical process whose purpose is to protect production cycles, equipment and stored materials from excess moisture. DanVex industrial units are built for continuous operation in demanding conditions and are organised in two complementary lines: the mobile DEH-i Series and the stationary DEH-K Series. Mobile units give flexibility to construction sites, restoration projects and temporary storage; stationary systems with capacities up to 1000 L/day become permanent building services in factories and logistics centres.

The two series share one engineering platform — designed for aggressive atmospheres and temperature swings. Heat exchangers across the range carry electro-deposited E-Coating anti-corrosion protection; Hot Gas Defrost preserves performance at low temperature; high-pressure centrifugal blowers develop the static pressure needed to move air through large volumes or extended ductwork. Modbus RTU RS-485 connectivity is standard on both series for direct integration with building management systems. Low-GWP refrigerants — R-290 on the mobile units and R-32 on the stationary ones — deliver environmentally responsible operation. The result is a complete industrial range, from stationary inverter efficiency to mobile field ruggedness, with stable precise climate control and predictable return on investment for professional installations.

Engineering standards across the range

What makes a DanVex dehumidifier "industrial" is not the size of the cabinet but a set of design decisions shared by both lines — technologies that set this equipment apart from consumer dehumidifiers carrying an "industrial" label:

E-Coating heat exchanger

An electrochemical anti-corrosion layer on the aluminium fins and copper tubes. Resists construction dust, organic acids, salt solutions, chlorine-laden cleaning agents and salt vapour typical of industrial environments. Standard across the DanVex industrial range.

High-pressure centrifugal blower

An industrial-grade centrifugal design delivers the static pressure required for large-scale installations. Holds airflow against loaded G4 filters, long duct runs and aggressive industrial conditions. Two motor implementations across the range: Smart-Inverter EC (variable 0–100%) and Step-Control AC (multi-speed).

Hot Gas Defrost

A fast defrost cycle by routing hot compressor gas directly into the coil. Operation is preserved from +10 °C (DEH-i Series) or +5 °C (DEH-K Series). Conventional defrost methods — passive (compressor stopped, fan running) or electric heater — take 20–30 minutes, during which dehumidification stops completely.

Modbus RTU RS-485

Standard on every model in both series. Direct integration with BMS, SCADA and facility monitoring. Centralised supervision of several units from one screen replaces field inspection rounds — a tangible labour-cost reduction in multi-unit installations.

Environmentally responsible refrigerants

R-290 on the mobile DEH-i Series; R-32 on the stationary DEH-K Series. Low-GWP refrigerants with high thermodynamic efficiency at industrial-dehumidifier capacities.

Pre-configured for installation (DEH-K)

Stationary units ship ready to connect: built-in sensors, digital controller, 5-in-1 sensor, UV + Anion modules, G4 filter and pre-charged refrigerant. Final commissioning is limited to the electrical connection (certified electrician) and the condensate drain — with no separate add-on modules to buy for standard operation.

Frequently asked questions

What is an industrial dehumidifier?
An industrial dehumidifier is a heavy-duty dehumidification system designed for continuous operation in production, storage and infrastructure environments where humidity affects product quality, equipment preservation or building condition. Industrial units differ from residential and light-commercial ones in five practical ways: higher capacity (up to 1000 L/day per unit), anti-corrosion-protected heat exchangers, high-pressure centrifugal fans, professional control interfaces (Modbus and BMS integration) and structural ruggedness for continuous duty. Typical applications: warehouses, production halls, food and pharmaceutical facilities, plant growing, flood restoration.
How does an industrial dehumidifier differ from a commercial or residential one?
Residential and light-commercial dehumidifiers (typical capacity 10–30 L/day) are designed for occasional use in occupied rooms — basements, bedrooms, small offices. They use simple axial fans, basic on/off control and consumer-grade refrigeration components. Industrial dehumidifiers (typically 59–1000 L/day) are built for continuous heavy duty in production environments. The technical differences: high-pressure centrifugal fans, anti-corrosion-protected heat exchangers, three-phase supply on the higher capacities, BMS integration over Modbus RTU RS-485, IP22–IPX4 protection and refrigeration circuits designed for years of continuous operation rather than intermittent use.
How do I choose between a mobile and a stationary industrial dehumidifier?
The nature of the humidity problem drives the choice, not the capacity. Choose mobile (DanVex DEH-i Series) when the problem is temporary, spread across several sites or a fixed installation is impractical — construction sites, flood restoration, drying tasks, rotation between facilities, food and pharmaceutical production support during wash-downs. Mobile units run on standard single-phase 220–230 V, on wheels, with a built-in tank or direct drain. Choose stationary (DanVex DEH-K Series) when humidity control is a permanent building or process requirement: factories, large warehouses, food and pharmaceutical production, plant growing. Stationary units are usually on three-phase 380–415 V, with permanent installation, top-discharge airflow and optional ducted distribution. The DEH-2K bridges the two categories: a stationary unit with the full premium feature set on standard single-phase supply for sites without a three-phase supply.
How is industrial dehumidifier capacity measured?
Industrial dehumidifier capacity is usually quoted in litres per day (L/day) at 30 °C / 80% RH — the international industry-standard test condition that allows direct comparison between manufacturers. Some datasheets quote capacity in kilograms per hour (kg/h) — the same physical quantity expressed differently: a kilogram of water equals a litre. To convert: kg/h × 24 = L/day. Actual capacity depends on ambient and operating conditions. For precise sizing in colder or drier conditions, request a project capacity calculation rather than relying on the nameplate alone.
Do industrial dehumidifiers need professional installation?
Mobile industrial dehumidifiers (DanVex DEH-i Series) are deployed by the operator — a standard single-phase 220–230 V socket, wheels for positioning, direct drain to a floor drain or a tank; no specialist is needed. Stationary units (DanVex DEH-K Series) usually require professional installation: a three-phase electrical connection by a certified electrician, condensate-drain plumbing and (for ducted operation) HVAC-contractor work on the duct connections. The unit itself ships pre-configured — all sensors, controller, UV + Anion modules, G4 filter and refrigerant are installed and set at the factory; final commissioning comes down to the electrical connection and the drain. DanVex provides installers with full technical documentation, wiring diagrams and BMS integration notes; for complex projects the dealer network — including the UAE with the Dubai warehouse — provides on-site engineering assistance.
What industrial dehumidifier capacity do I need for my space?
A practical starting point for typical industrial 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 warehouse needs around 150–200 L/day; a 1000 m² facility around 500–700 L/day. This rule covers steady-state dehumidification of a closed space with ordinary occupancy. Requirements rise further for pool halls (continuous water evaporation), food production with active wet cycles, grow rooms (active transpiration) and high-infiltration spaces (open doors, gaps in external walls) — where 2–3 times the rule may be needed. For precise sizing, contact us with room dimensions, target humidity, moisture source and operating temperature — we provide free project calculations.
Why does refrigerant choice matter in industrial dehumidifiers?
Refrigerant choice has two practical consequences for the industrial buyer: environmental compliance and energy efficiency. The DanVex industrial range uses low-global-warming-potential refrigerants by default: R-290 (propane) on the mobile DEH-i Series and R-32 on the stationary DEH-K Series. Both are thermodynamically more efficient than legacy alternatives at industrial-dehumidifier capacities — meaning less energy consumed per litre of water removed.
