Dehumidifier Solution — Compressor & Semiconductor PCB ODM
SOLUTION DEFINITIONA dehumidifier solution controls compressor-based or semiconductor (TEC) dehumidification cores with precise humidity sensing, smart defrosting, tank-full protection and multi-mode operation (continuous/laundry/sleep). MJX offers production platforms for both routes, covering 12–50L/D home units and compact wardrobe dehumidifiers.
Pain Points We Solve
- Dehumidifier demand is surging with extreme weather, but well-engineered controls are rare
- Poor defrost logic and low-temperature guards on compressor units cause batch compressor failures
- Humidity sensor drift makes users feel the machine "does nothing"
- UL/CE energy requirements for export are hard to pass with generic designs
Key Features
Dual PlatformsCompressor (12–50L/D) and TEC (0.5–1.5L/D compact) fully covered
Precise ControlIndustrial-grade sensing with factory calibration, ±3%RH accuracy
Smart DefrostTime + evaporator-temperature dual-condition defrost; <5°C protection extends compressor life
Multi-scene ModesContinuous / smart / laundry / sleep with < 38dB tuning
Tank-full SafetyFloat switch + firmware double protection, auto shutoff, continuous drain supported
ConnectedWiFi app remote control, humidity history, voice assistants

FAQ
Compressor or semiconductor — which route?
For 20L/D+ home units, compressor (efficient, cost-effective); for wardrobe/bedroom/car (<2L/D), TEC (silent, compact, low cost). We provide production platforms for both.
How do you prevent inflated capacity claims?
Units are rated at standard conditions (27°C/60%RH and 30°C/80%RH) with a factory capacity test fixture and reports delivered — third-party verifiable.
Can it pass UL/ETL?
Power and protection circuits follow UL design rules (compressor protection, flame-retardant specs). We have UL co-certification experience and accompany submissions.
How is sensor drift handled?
Two/three-point factory calibration plus firmware temperature compensation yields ±3%RH整机 accuracy; calibration fixtures included.
Can it double as a laundry dryer?
Yes — laundry mode (high fan + continuous + timer) is standard, and a dedicated dryer line can share the platform.
