Industrial condenser dryer DH 30

Robust, efficient, powerful – a professional dehumidifier with air circulating EC radial fan

The DH 30 ensures a constant storage atmosphere
The DH 30 is ideally suited for the dehumidification of staff rooms or fitness areas
DH 30 – a high-quality dehumidifier "made in Germany"

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 0 °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:

Well-orchestrated components

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.

Make use of Trotec's 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.

Trotec is the only provider of this advantage:

Thanks to the unique option of non-binding trial operation you will invest solely in solutions which have verifiably proven their worth in everyday operation meeting your individual on-site requirements. The stationary units will not be ordered until you are fully satisfied with our concept. The only costs incurred consist of an inexpensive hiring flat rate for the time of test operation.

Just give us a call at +49 2452 963-777 – our industry consultants will be pleased to help you personally and provide information regarding our best practice industrial services. Or send a request indicating your personal requirements directly to our industry experts. We will answer promptly!
