Add-Ons & Custom Options of Rinwang Dehumidifier
Custom performance and presentation: enable smart connectivity, choose branded finishes, and specify built-to-order features to fit your environment, compliance needs, and budget.
Critical parts use anti-corrosion materials/coatings to resist salt spray and chemical exposure, extending service life in marine docks and chemical plants under harsh conditions.
Choose a large tank or external drain hose for continuous discharge, reducing manual emptying. Square or round adapters fit ducts; ceiling-mounted or floor-standing installs stay simple.
Automatic defrost prevents icing in winter or low temperatures, keeping the evaporator efficient and dehumidification continuous, while reducing manual maintenance and improving performance in cold environments.
A high-accuracy sensor and smart controller monitor in real time; set a target RH and the unit automatically starts/stops or modulates power to maintain stable humidity.
An upgraded centrifugal fan provides higher airflow and wider coverage for rapid, even distribution—balancing humidity across corners and accelerating dehumidification in large spaces.
Wi-Fi and mobile app control. Monitor status, adjust settings, and schedule on/off from anywhere—keep warehouse humidity on target and integrate with your facility’s IoT.

How to Choose the Right Industrial Dehumidifier
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.
1. Calculate Your Space Volume
Tell us your length × width × height of the area to be dehumidified. Include adjoining spaces if they’re connected.
💡Pro Tip:
Add 20% to your calculation for areas with high air circulation or multiple openings.
Example: 20m × 15m × 4m = 1,200m³ space
2. Consider Operating Temperature
Different models perform optimally at different temperature ranges. Match the dehumidifier to your environment.
💡Pro Tip:
For cold environments below 10°C, choose models with hot gas defrost systems.
Standard: 5-35°C, Low-temp: -10-25°C
3. Determine if the room is airtight
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.
💡Pro Tip:
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%)
4. Determine Current Humidity Levels
Measure existing humidity with a hygrometer. Higher humidity requires more capacity for faster moisture removal.
💡Pro Tip:
Most industrial applications require 40-60% RH for optimal conditions.
80% RH → 50% RH requires higher capacity initially
5. Assess Power Requirements
Check available electrical supply (voltage, phase, amperage). Ensure adequate power capacity for continuous operation.
💡Pro Tip:
Consider power consumption costs - higher efficiency units save money long-term.
Single phase: 220V, Three phase: 380V
6. Evaluate Installation Location
Consider drainage options, ventilation requirements, noise restrictions, and accessibility for maintenance.
💡Pro Tip:
Plan for condensate disposal - gravity drain is most reliable for continuous operation.
Ceiling height minimum 2.5m, floor drain within 3m
