Industrial condenser dryer DH 30
Robust, efficient, powerful – a professional dehumidifier with air circulating EC radial fan
Brings versatile dry keeping applications to your own four walls
Installing this dehumidifier that comes prepared for wall mounting is as simple as its fully automatic operation for the permanent dry keeping of staff rooms, productions halls or storage facilities. The DH 30 automatically regulates the humidity via hygrostat control to an ideal level at which corrosion, condensation and mould stand no chance.
The robust dehumidifier impresses with a high dehumidification performance even at low temperatures without exception. Its professional hot gas automatic defrost system, which operates based on the bypass procedure, permits the application to a range of 5 °C – ideally suitable for use in cold halls or storage facilities.
Low in maintenance, yet highly effective – ideal for continuous operation
Consistently designed with a close focus on preserving values, this corrosion-protected construction made of powder-coated, galvanized sheet steel accommodates an industrial condenser dryer of maximum durability. Combined with its CDC-coated heat exchanger it renders the high-quality dehumidifier DH 30, manufactured in Germany, extremely resistant to environmental influences – even in especially reactive air environments containing a high percentage of solvents, chlorine or salt.
The combination of high efficiency level and low-maintenance design predestines the DH 30 for fully automatic, hygrostat-controlled permanent drying applications in numerous fields of application. Due to the autonomous recirculation operation the device can even be subsequently integrated in virtually any working environment.
An effective procedure for maximum profitability
In high-volume recirculation operation this industrial dryer withdraws the major part of the humidity from the air in keeping with the target humidity level preselected via the hygrostat. A high level of efficiency is ensured by the double-flow EC radial fan and the high-performance compression refrigeration system of the DH 30.
The dry air supplied to the room is simultaneously heated by the process with the result that the input of conventional heat and ventilation energy can be substantially reduced. Owing to a coefficient of performance (COP) of 2.5 the DH 30 is able to generate 2.5 kW of heat output from every kilowatt used during dehumidification.
In addition, the DH 30 comes equipped with an automatic hot gas defrost system operating based on the bypass procedure. To make sure the evaporator is protected from frost and kept clear of ice, a special solenoid valve opens briefly and redirects the hot refrigerant from the compressor directly to the evaporator (instead of to the condenser) via a bypass.
For this reason, the DH 30 requires only very short defrost phases – ideal for an effective dehumidification in low-temperature surroundings such as unheated rooms. Furthermore, it improves the performance level and thus increases the net overall equipment effectiveness of this dehumidifier.
Diverse application possibilities
Unless effectively controlled, humidity can lead to manifold problems for production processes, furniture and equipment or stored goods. An ideal humidity regulation does not just prevent rust, rot, material decomposition or a reduced quality in processing and storing goods, its also a reliable protection against mould growth. When mounted to the wall the DH 30 can be used for very different fields of application including:
- Humidity regulation in staff rooms, changing rooms, recreation and break rooms
- Dry keeping of changing rooms, fitness studios and store rooms for biker gear or skiing equipment
- Constant humidity levels in car pools, workshops, on test stands or in production halls
- Dehumidification in archives, libraries or for your collections
- Dehumidification of water processing facilities and pump stations to prevent condensate formation on pipes and pumps
- Humidity regulation when storing natural products, for the quality assurance in timber yards or when storing raw tobacco
- Preventing corrosion in electric control centres, boiler plants, turbines and pipe systems in power plants or when storing car body shells and metal components
- Humidity regulation in computer centres, control rooms etc. Humidity regulation in the food industry, e.g. in cheese dairies or for the production of confectionery
The DH 30 exclusively houses high-quality components that are particularly well-matched to work together, all guaranteeing durability and a long lifetime.
Evaporator and condenser of the DH 30, for instance, are provided with a cathodic dip coating (CDC) that is resistant to solvents and corrosion as well as to acids and alkalis.
Accordingly, the high-performance refrigerant compression system is extremely resistant to environmental influences and guarantees a high dehumidification performance in continuous operation – even in cold surroundings.
The DH 30'S powerful, air circulating radial fan certainly makes for a good match. This double-flow fan is driven by a smoothly running, durable EC motor that operates in a particularly energy-efficient manner and through speed control ensures an optimum air flow rate at all times. By means of a selector switch the fan can be set to run in continuous operation ensuring maximum air flow rates or be activated or deactivated via hygrostat control as an additional option to save energy.
The sophisticated complete equipment of the DH 30 renders additional equipment options virtually obsolete. However, should you want to discharge the accumulating condensate to an elevated area, the device can also be supplied with an integrated condensate pump as order option.
In the DH 30 H version also available with heating function
For operational environments without heating, the air in which is not only to be kept dry but also warm, the industrial condenser dryer DH 30 is also available as DH 30 H version with an integrated additional heating in thermostat operation. Thanks to a heating capacity of 2.8 kW, the dry air blown out into the room can also be heated at the same time on a large-volume basis in this way.
Apart from the integrated hygrostat for humidity control, the DH 30 H version is equipped with an additional thermostat for this purpose, allowing for the variable preselection of the desired room temperatures between 0 and 40 °C. Heating then takes place automatically.
In contrast to the CEE-7/7 connector variant of the DH 30 standard version, the power connection of the DH 30 H is implemented via plug-in terminal.
Make use of our best practice industrial services
Since every industrial undertaking has characteristic process flows, installations and facilities, every air treatment solution demands case-specific device configurations. All in all, the combined effects of air currents, humidity conditions and temperature fluctuations are often hard to calculate on a purely theoretical basis, e.g. in airlock areas or on conveying paths. The consequence: Unnecessary additional costs due to an overestimated demand or – even worse – solutions not working sufficiently in real life.
You can count on our experts
In order to precisely calculate the demand in the industry and to develop tailor-made concepts for climate conditioning experienced climate specialists are needed. Rely on our team of experts as well as the industrial services: We analyse the individual requirement situation with you present on site, determine the specific demand for devices and develop a tailor-made project solution right up to the exact positioning of the devices.
Before the planned stationary units are installed, our service team first works with mobile versions of the drying units as part of a trial run. These can be put up without any difficulty or the need for structural changes.
During this validation phase we document all relevant climate parameters such as air temperature, relative humidity, dew point or flow rate for a final optimization of the requirement calculation.
