Desiccant Rotor Dehumidifier
Desiccant rotor dehumidifiers for lower dew-point applications and process environments requiring stable dry air.
Compare rotary desiccant models with removal capacity rated at 20°C/60% RH, then confirm process air, reactivation and installation requirements.

Product selection should be confirmed against temperature, target humidity, airflow, drainage, power supply, and installation conditions.
DEFINITION
What is a desiccant rotor dehumidifier?
A desiccant rotor dehumidifier adsorbs moisture from process air with a rotating wheel. A separate heated reactivation air stream regenerates the rotor and carries moisture away. This range is reviewed for lower-temperature or lower-humidity duties using both air paths and the required outlet condition.
Yakeclimate designs and manufactures industrial dehumidification equipment for complex climate applications, with a focus on agriculture and energy projects.

PPD means US pints per day, converted as L/day × 2.113 and rounded to the nearest whole number. L/day retains the original rated precision. Conversion is not an AHAM/DOE test result; ratings at different conditions cannot be ranked directly.
COMPARE RATING CONDITIONS
When to compare desiccant and refrigerant equipment
Compare both routes against entering-air temperature/RH, target humidity or dew point, airflow and the available reactivation arrangements. Lower-temperature or lower-humidity duty can justify a desiccant review. Conventional commercial and industrial duties can also be assessed with refrigerant models. The RY ratings use 20°C/60% RH; the RYCM and RYCF refrigerant ratings use 30°C/80% RH, so dividing their rated L/day values cannot establish an efficiency advantage.
- RY desiccant capacity ratings
- 20°C / 60% RH
- RYCM / RYCF refrigerant capacity ratings
- 30°C / 80% RH
TWO AIR PATHS
Process air and reactivation air: plan both paths
The rotor adsorbs moisture from the process air. A separate reactivation air stream carries the released moisture away. Use both airflow columns in the model table to prepare the installation; confirm inlet boundaries, discharge routes and service access with the selected model.

Process-air path
Entering process air → rotor → dry-air outlet. Provide inlet temperature/RH, required process airflow and the target outlet condition.
Reactivation-air path
Reactivation inlet → heating and rotor regeneration → moisture-laden exhaust. Provide the proposed intake and exhaust routes and the available electrical supply.
Installation review
Keep the two air paths explicit in the layout. Confirm pressure requirements, exhaust discharge location, access and permitted changes to the served space.
PROJECT PERFORMANCE
Confirm low-temperature and low-dew-point duty
The catalogue capacity is tied to 20°C/60% RH; the applicable temperature range is a separate field. Send the actual entering-air condition and the target RH or dew point to confirm removal, outlet temperature, airflow and pressure. These ratings do not establish one guaranteed outlet dew point for every model or installation. A performance curve or a project-specific value requires corresponding model data. Low-temperature performance can be tested in our laboratory against your project conditions; submit your requirements to agree the test scope and request the resulting curve.
- Confirm temperature, RH or dew point
- Inlet → outlet
- Review at the actual duty
- Flow + pressure
POWER & SERVICE
Power, installation and service inputs
Retain the listed 50Hz supply and Rated Power definition when planning electrical service. Rated power is not a measurement of continuous all-day energy use. Confirm the duty cycle, reactivation exhaust path, dimensions and service access. A 60Hz supply or another regeneration configuration requires a project review; the listed models do not establish steam or gas regeneration availability.

SELECTION STEPS
How to select the right configuration
- Step 1 — define the operating conditions. Record the temperature range, current and target relative humidity, moisture load, and the volume of the room or enclosure to be protected.
- Step 2 — confirm the site constraints. Check the available power supply, drainage method, airflow or static-pressure requirement, and installation space; for ceiling, cabinet, or portable mounting confirm the fixing method and service access.
- Step 3 — review the rated data and confirm the configuration. Compare the rated capacity in l/24h and the surrounding specification values in the table against the recorded conditions, then confirm the configuration with Yakeclimate before ordering.
FAQ
Frequently Asked Questions
Is the Desiccant Rotor Dehumidifier capacity rating based on standard testing conditions?
Rated capacity is published under the named condition in the specification table (for example 30°C/80% RH, in l/24h). Actual moisture removal depends on operating temperature, humidity, airflow, and installation conditions.
Which applications can the Desiccant Rotor Dehumidifier support?
The applications listed on this page are evaluation starting points. Final suitability depends on the moisture load, temperature, airflow, and installation limits of the project.
How does Yakeclimate support project configuration?
We co-develop application-specific dehumidification equipment around the operating conditions, interfaces, and integration requirements of the wider project or system.
What is a rotary desiccant dehumidifier?
It uses a rotating desiccant rotor to adsorb moisture from process air and a separate reactivation air path to remove that moisture from the rotor. Compare both airflows and the rated removal condition by model.
How does a desiccant dehumidifier work?
The rotor moves between moisture adsorption and heated regeneration zones, allowing process-air drying and reactivation to continue. The working-principle guide in the related resources explains the two air paths.
Which desiccant model should I buy for a low-dew-point duty?
Submit the entering-air condition, target dew point, process airflow and reactivation arrangements for a model-specific review. A capacity rating at 20°C/60% RH does not guarantee a particular low outlet dew point.
Can I compare desiccant and refrigerant L/day ratings directly?
These ranges use different rating conditions: 20°C/60% RH for the RY desiccant models and 30°C/80% RH for the RYCM/RYCF refrigerant models. Compare performance at the same actual project condition before selecting.
Do these models suit battery manufacturing dry rooms?
Battery manufacturing dry rooms and large central custom dry-room systems are outside the scope of this product range. The listed industrial desiccant ratings do not establish suitability for those processes.
