Hoffman H2OMITTER VS DH5-80 Dehumidifier – What’s Difference
The Hoffman H2OMITTER Thermoelectric Dehumidifier and the Blue Jay DH5-80 Cabinet Dehumidifier are both semiconductor refrigeration dehumidifiers that utilize the Peltier effect, primarily designed for use in confined spaces such as electrical cabinets and control cabinets to prevent condensation and corrosion. Although the dehumidification principles are the same, there are significant differences in design concepts, performance emphasis, and target applications.
Hoffman H2OMITTER vs DH5-80 Dehumidifier
| Specification | Hoffman H2OMITTER Dehumidifier | DH5-80 Dehumidifier |
| Voltage | 24V DC, 115V AC, 230V AC | 85V-265VAC/DC |
| Dehumidification Capacity | 230ml/day | 350ml/day |
| Maximum Power Consumption | 84W | 75W |
| Diemension | 150 x 135 x 142mm | 138 x 150 x 70mm |
| Dehumidifier Enclosure Material | ABS | Aluminum Alloy |
| IP Rating | IP54 or IP55 | IP54 |
| Installation | Din rail mounting | |
| Application | Removes moisture from the air within an enclosure (Industrial control cabinets, electrical panels, telecommunication equipment boxes, outdoor cabinets, etc.) | Used for various electrical enclosures including GIS control cabinets, HV/LV control switchgear, Ring network cabinets, Mechanical control cabinets, Box-type substations, and Dry-type substations. |
According above comparison, both of them have their advantages. The DH5-80 cabinet dehumidifier has a 50% higher dehumidification capacity than the Hoffman H2OMITTER. This means that the DH5-80 from Blue Jay is more suitable for electrical enclosures that require higher dehumidification capacity or have larger volumes, while the Hoffman is more suitable for smaller spaces or where humidity issues are less severe. Blue Jay DH5-80 dehumidifier consumes less power than Hoffman H2OMIT. In the long run, Blue Jay may be more energy efficient.
Conclusion
Conclusion
Selecting the right dehumidifier depends on your specific needs. The Blue Jay DH5-80, with its excellent temperature adaptability and compact design, proves to be a more reliable and professional option for electrical cabinets located in extreme temperature conditions (e.g., frigid outdoor winters, high-temperature equipment rooms, or unheated/uncooled areas) or in situations where cabinet space is extremely limited and a high dehumidification capacity is crucial.
