ASE 200-300-400 Portable Adsorption Dehumidification

PORTABLE ADSORPTION DEHUMIDIFICATION
ASE 200-300-400
IDEAL FOR DRYING AT LOW TEMPERATURES IN CONSTRUCTION, WATER DAMAGE AND WATERWORKS INDUSTRIES 
PORTABLE ADSORPTION DEHUMIDIFIERS – INTRODUCTION
ENSURING DRY CONDITIONS AT LOW TEMPERATURES
Adsorption dehumidification ensures dry conditions at low temperatures. This makes the ASE portable range the obvious choice for drying out new buildings or water damage during the winter season and for maintaining low levels of relative humidity at facilities with a low ambient temperature.
Humidity problems are most often associated with hot and damp environments, and usually a condense drying dehumidifier is applied. However, at ambient temperatures below 10°C condensation is not very easily achieved, whereas humid air and moisture from materials, open water surfaces, and production processes can cause serious damage at even very low temperatures.
The ASE portable range offers reliable control of the relative humidity of the air, and drying out water damage or newly constructed buildings even at winter temperatures. After all, accidents happen regardless of the seasons, and construction work goes on all the year round.
Sturdy and compact design
The portable units have been designed for easy handling and transportation. The sturdy stainless steel cabinets are surprisingly compact and low weight compared to capacity. The countersunk control panel is well protected and folding handles for carrying make the units easy to stack during transportation and storage.
Key features
- Ensures dry conditions at low temperatures
- Reliable control of the relative humidity of the air
- Sturdy and compact design
- Cabinet in stainless steel/hot galvanized powder coated steel
- Designed for easy handling and transportation
- Low weight
- Easy to stack during transportation and storage

Easy installation and service
The portable units are fast and easy to install. Just connect one or two hoses to the dry air and one hose to the regeneration air outlet and lead it to the outside. The cabinet provides easy access for internal cleaning and service, and the air filter can be changed without opening the cabinet.
High-performance operations
The built-in hour and energy counter shows the accumulated hour and energy consumption. The energy counter of the ASE 200/ASE 300 is very precise and has the MID approval which is highest marked standard. The portable range offers reliable high-performance operations at low temperatures and easy installation ensure fast results in drying out constructions and emergency situations minimizing the long-term damage caused by flooding. The portable units can run continuously, or they can be controlled by internal hygrostat with the ASE 200/ASE 300 or external hygrostat with the ASE 400.
How the dehumidifier works
An adsorption dehumidifier is divided into two zones. In the drying zone humid air from the air inlet passes through a silica gel rotor that adsorbs the moisture and the dry air is returned to the room. In the regeneration zone hot air is blown through the rotor drying out the silica gel and carrying the moisture through the connected hose to the outside.

Applications

PORTABLE ADSORPTION DEHUMIDIFIERS
ASE 200
The ASE 200 is a robust compact adsorption dehumidifier with a silica gel rotor as standard. Process air is drawn into the dehumidifier and through the rotor, which slowly turns between two sections in the dehumidifier. The silica gel rotor adsorbs the moisture from the air in the drying section. This moisture is removed again by blowing hot air through the rotor in the regeneration section. The process air leaves the dehumidifier as dry air, and the moisture is led out of the room through the regenerated air outlet. 
- MID approved energy counter
- Hour counter
- Internal humidistat
- One common fan for process air and regeneration air
- Cabinet in stainless steel / hot galvanized powder coated steel
- Low weight
- PTC regeneration heater
- Robust and compact metal construction
- Carrying handle
- Easy internal access for service and maintenance
- Four rubber bumpers to fix the unit in place
- Flexible dry air outlet
