Don’t let excess moisture cost you time, money, and reputation. Our industrial dehumidifiers provide reliable moisture control solutions across diverse industries and applications.
We’ve successfully provided moisture control solutions for diverse applications. Our engineering team can design a custom solution for your specific requirements.
Founded in 2021 in Weifang, Shandong Ruiwang Industrial Technology designs and manufactures industrial and commercial dehumidifiers, including ceiling-mounted systems. We provide OEM/ODM customization, engineering support, and low MOQs to serve warehouses, greenhouses, pools, basements, and food facilities with dependable humidity control.
Making the wrong choice costs time and money. Follow our 6-step guide to select the perfect dehumidifier for your specific application and avoid costly mistakes.
Measure length × width × height of the area to be dehumidified. Include adjoining spaces if they’re connected.
Add 20% to your calculation for areas with high air circulation or multiple openings.
Example: 20m × 15m × 4m = 1,200m³ space
Different models perform optimally at different temperature ranges. Match the dehumidifier to your environment.
For cold environments below 10°C, choose models with hot gas defrost systems.
Standard: 5-35°C, Low-temp: 2-25°C
Room ventilation will bring extra moisture from outside into the room, causing the humidity in the room to be unstable and affecting the dehumidification effect.
If the room isn’t airtight, reduce infiltration—seal gaps, add vestibules/air curtains, and keep slight positive pressure (+5–12 Pa).
Target +5–12 Pa pressurization; at loading docks, add air curtains (can cut doorway infiltration ~60–80%)
Measure existing humidity with a hygrometer. Higher humidity requires more capacity for faster moisture removal.
Most industrial applications require 40-60% RH for optimal conditions.
80% RH → 50% RH requires higher capacity initially
Check available electrical supply (voltage, phase, amperage). Ensure adequate power capacity for continuous operation.
Consider power consumption costs - higher efficiency units save money long-term.
Single phase: 220V, Three phase: 380V
Consider drainage options, ventilation requirements, noise restrictions, and accessibility for maintenance.
Plan for condensate disposal - gravity drain is most reliable for continuous operation.
Ceiling height minimum 2.5m, floor drain within 3m

Stock units: 1 pc MOQ. Custom builds: 5 pcs MOQ (branding, coil coatings, control protocol, stainless options, etc.). (Made-to-order lead times apply.)
Models are designed to comply with EN/IEC 60335-2-40 for CE marking; UL/ETL listing to UL 60335-2-40 is available on request. Enclosure IP ratings are specified per IEC 60529 (e.g., IP54/IP55), with NEMA 4X options for corrosive sites. Refrigerant selections (e.g., R32, R410A, R290) support ongoing transitions under the U.S. AIM Act HFC phasedown to 85% by 2036 and the EU F-gas 2024/573 framework; statements of conformity or transition plans can be provided for projects.
Cabinets use smooth, cleanable finishes; coils drain to a sloped drain pan and condensate is routed via trapped drain lines to prevent standing water. Design follows industry guidance that drain pans be sloped ≥ 10 mm/m (1/8 in/ft) toward the outlet to reduce microbial growth.
For corrosive environments (natatoriums, coastal sites), we offer e-coated coils (full-immersion electro-deposition) and 304/316L stainless-steel cabinetry options.
At lower entering air temperature or humidity, latent capacity decreases relative to rating conditions; for cold rooms we use hot-gas (bypass) or reverse-cycle four-way-valve defrost, and electric defrost where appropriate. Defrost entry/exit can be time- and/or temperature-based and is field-adjustable to suit the application.
We rate industrial dehumidifier capacity at 30 °C/80% RH in a controlled psychrometric chamber (still-air). AHAM-style ratings at 26.7 °C/60% RH can be provided for comparison on request.
