Adsorption dryer
CSrental has a wide range of adsorption dryers in its assortment that are suitable to rent. The MDC adsorption dryer offers a temporary or stationary solution to a moisture problem in the construction, shipping, industrial, pharmaceutical and food industries, petrochemicals and in the office or warehouse. An MDC adsorption dehumidifier takes the humidity out of the room. The consequence of rooms that are too wet is that mold can develop and, in some cases, result in a loss of quality. Renting an adsorption dryer can help maintain quality and create a better working environment.

Adsorption dryer deployment
Â
An adsorption dryer is mainly used when the following conditions occur:
- A very low relative humidity of less than 35% must be achieved, for example in munitions warehouses and the pharmaceutical and chemical industries;
- Work is only carried out at lower temperatures than 8°C, for example in cold storage;
- Low temperatures are necessary or climatically present, for example tank coating and ship restoration.
CSrental has several variants of the adsorption dryer in its product range. MDC’s adsorption dryers have capacities from 160 m³/h to 5,000 m³/h. A steel frame and a protective tarp make the adsorption dryer suitable for rental. The adsorption dryers are equipped with monitoring, so air temperature and relative humidity can be consulted at any time.
The operation of an adsorption dryer
The adsorption dehumidifier uses the moisture-absorbing ability of substances such as silica gel and lithium chloride. These two substances are impregnated on a rotating ceramic wheel. As a result, the moist air is blown out of the room. The moisture is absorbed by the hygroscopic material contained in the adsorption dehumidifier, resulting in dry air. The adsorption dryer then blows the dry air into the room. With the MDC adsorption dryer, a process takes place over two separate air ducts.
Water quality requirements of the adsorption dehumidifier
Note: Before operating the adsorption dehumidifier, inventory the room and take any measures as necessary. The adsorption dehumidifier should not be used in:
- Environments where particles, gas, smoke and the like may be drawn in due to created negative pressure, which may adversely affect chimneys, furnaces or other similar equipment;
- In areas with a potentially explosive atmosphere;
- In areas with an aggressive atmosphere (caused, for example, by chemicals);
- In areas containing water with a pH lower than 7.0 or higher than 7.4;
- In areas with salt or liquids with a salt content > 1% e.g. salt baths;
- In humid areas of indoor swimming pools;
- In areas with ozone treated air, high solvent concentrations or high dust load.
Frequently Asked Questions about Adsorption Dryers
What is an adsorption dryer and when should you choose one?
An adsorption dryer reduces humidity via adsorption on a hygroscopic rotor (e.g. silica gel / lithium chloride). Choose this principle for low temperatures (< 8 °C), very low target RH, or whenever condenser dryers are insufficient (cold storage, pharma, chemical, marine, industrial).
How does an MDC adsorption dryer work?
MDC units use a rotating ceramic sorption wheel with two separated airstreams: a process air stream that is dried and a regeneration air stream that dries the wheel again. This delivers a continuous flow of dry air back into the room.
What capacities are available?
The range spans MDC-160 (≈160 m³/h) up to MDC-5000 (≈5,000 m³/h). Selection depends on room volume, target RH, temperature, infiltration and process load. CSrental calculates the required dry air volume (m³/h) and regeneration air for an optimal setup.
How does energy use compare to conventional adsorption dryers?
The MDC line is engineered for efficient drying. In practical use, MDC-5000 consumes around 40 kW/h where conventional alternatives are ~80 kW/h (≈ 50%), subject to conditions and configuration.
In which sectors are adsorption dryers used?
Typical applications include construction/renovation, marine, pharmaceutical & food, petrochemical, munitions storage, and offices/warehouses where stable low RH and product quality are critical.
Can performance be monitored?
Yes. Optional (remote) monitoring provides real-time air temperature and relative humidity insights via PC or remote access, supporting quality assurance and planning.
Are there limitations or precautions for use?
Do not use in areas with potentially explosive atmospheres (ATEX), aggressive/chemical atmospheres, high dust load, ozone-treated air, or where created negative pressure could impact chimneys/furnaces. Also avoid environments with water pH < 7.0 or > 7.4 or salt content > 1% (e.g. salt baths).
How quickly can CSrental deliver and install?
With ample stock and rental-ready designs, CSrental can often deliver and commission the same day (incl. hoses/couplings). Feel free to contact us for Customised Advice.
