Industrial condenser dryer DH 15

The perfect solution for commercial dry keeping applications and ideally suited for rooms open to the public or with staff coming and going

The DH 15 keeps equipment rooms and storage facilities reliably dry
The DH 15 creates ideal ideal storage atmosphere for moisture-sensitive goods
DH 15 – a high-quality dehumidifier "made in Germany"

Easily outdries the competition with their back to the wall

Characterizing features of the DH 15 include not only its distinctive German industrial design, stylish, minimalist, for maximum solidity, but also a high dehumidification performance even to low temperature ranges, technically brought to perfection for continuous operation with minimum maintenance effort.

A professional industrial dehumidifier to the core, originally produced by Trotec, having been developed and manufactured according to the highest of quality standards in Germany.

The DH 15 is a cost-effective solution for fully automatic humidity control in small and unheated business rooms by means of hygrostat control. It further impresses with its extremely stable design and a professional hot gas automatic defrost system enabling the DH 15's operation to temperatures of approximately 5 °C.

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 heat exchanger block that comes provided with protective coating it renders the professional dehumidifier DH 15 particularly resistant to environmental influences.

The combination of high efficiency level and low-maintenance design predestines the DH 15 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

The DH 15 automatically regulates the humidity to an ideal level at which corrosion, condensation and mould stand no chance. In 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 smoothly running AC axial fan and the high-performance compression refrigeration system of the DH 15.

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 reduced.

In addition, the DH 15 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 15 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 15 can be used for very different fields of application including:

Well-orchestrated components

The DH 15 exclusively houses high-quality components that are particularly well-matched to work together, all guaranteeing durability and a long lifetime.

The high-performance refrigerant compression system of the DH 15 is provided with an efficient protective coating ensuring a high resistance to corrosion and environmental influences.

The air flow rate of the axial fan, designed for a long lifetime, driven by a robust AC motor and equipped with solid metal blades for continuous low-maintenance operations, is optimally geared to the dehumidification capacity of this heat exchanger block.

Owing to the horizontally conducted recirculation air flow and its compact design the ready-for-use DH 15 is particularly well suited for the assembly above doors.

The operating elements of this industrial dryer are tamper-proof and protected against unauthorized access, which makes it also an ideal dehumidifier for public buildings, changing and staff rooms or museums.

The sophisticated complete equipment of the DH 15 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. Furthermore, a kit for rear panel installation is available upon request.

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.
