Combined cooling, heating, humidification and dehumidification for rooms that must hold both temperature and humidity.
- Cooling, heating, humidification and dehumidification in one cabinet
- Stable temperature and humidity band for test rooms and laboratories
- Configured per project with the required control tolerance
Model range and capacity are confirmed per project. Ask for the current specification sheet.
This range is not a menu of sizes: each frame changes the working surface, the airflow and the volume of water the unit has to handle, so the moisture load picks the frame rather than the floor area. The frames are configured per project, so capacity follows the room rather than a catalogue step. 3 models are published in the range, and each one is quoted against the condition it will actually see rather than the headline figure.
The tolerance is agreed before the cabinet is configured, because it decides how the cooling, heating and humidification stages are sized. A tighter band is a different machine, not a setting on the same one.
If the answer is a different platform, the selection check says so, with the calculation that led there.
Test chambers and room-level control
A constant temperature and humidity unit is often specified as a test chamber condition: a fixed temperature, a fixed humidity and a tolerance that the test method requires. The cabinet is configured to that band, with cooling, heating, humidification and dehumidification sized together rather than added one at a time.
For a room rather than a chamber, the same platform holds a production or storage band, and the tolerance is agreed per project because it depends on the room, the load profile and the sensors. Where only humidity has to follow a process, a dehumidifier platform is usually simpler to run.
Where constant temperature and humidity units are used
A constant temperature and humidity unit holds both values at once, because cooling, heating, humidification and dehumidification sit in one cabinet. The DVH platform is built in three frame sizes and configured per project for test rooms, laboratories, museums and production halls where the band matters in both directions.
Constant T&H dehumidifier questions
What tolerance can the unit hold?
The tolerance is agreed per project and depends on the room, the load profile and the sensors chosen. It is stated in the specification sheet rather than promised as a fixed figure.
Can it be used for humidity only?
The cabinet is always configured to the project. Where only humidity has to be controlled and the temperature follows the process, a dehumidifier platform is usually simpler and cheaper to run.
How is capacity selected?
From the simultaneous cooling, heating and moisture loads at the design condition, together with the internal gains of the equipment in the room; room volume alone is not enough.
Can the unit serve a museum or archive store?
Yes. Archive and museum stores are usually held in a narrow band for both temperature and humidity; a DVH cabinet is configured to that band and the tolerance is stated on the project specification sheet.
