Industrial condenser dryer DH 310

Versatile dehumidifier for continuous commercial and industrial dry keeping applications

Simply brilliant: Trotec's DH 310
DH310 with the housing open: Equally maintenance-friendly and powerful
A guarantor for keeping large areas dry

The perfect format for maximum dry keeping

The industrial condenser dryer DH 310 which can also be supplied in a stainless steel housing is characterized by a high dehumidification capacity, reliable continuous operation properties and practice-oriented equipment options alike. Designed for the operation whilst positioned on the floor, the device – given on-site preparation – can also easily be used when mounted to the wall or ceiling. Also it can be connected to existing ducted air systems.

The dehumidifier DH 310 comes with a smoothly running scroll compressor for constant, pulsation-free pressure to ensure an energy-efficient refrigeration. Combined with its self-regulating EC radial fan this robust industrial dryer allows for a constantly high dehumidification performance during continuous operation even at low temperatures.

Simple installation and start-up

The DH 310 is an effective dry keeping solution which can be installed immediately without the need for additional construction measures. It can also be subsequently installed to assist existing air treatment systems. Simply set it up, connect it to the power supply and install the condensate discharge hose – all done.

Unlike competition models of the same class the DH 310 has a condensate pump integrated as standard. As a result, the condensate can easily be discharged – even to elevated areas.

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 radial fan and the high-performance compression refrigeration system of the DH 310.

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 3 the DH 310 is able to generate 3 kW of heat output from every kilowatt used during dehumidification.

In addition, the DH 310 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 310 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. The robust design, high dehumidification performance and simple installation render the DH 310 an effective all-rounder for various fields of application:

Adjustment options

Due to the galvanized, powder-coated steel construction even the standard version of the DH 310 is highly resistant to corrosion and environmental influences. Furthermore, it can be adjusted to meet special requirements:

  • Stainless steel version
    Ideal for the application in areas with special hygienic requirements or particularly reactive air environments. The AISI 316 stainless steel housing can easily be cleaned, it is especially resistant to various chemical solutions like sulphuric acid or iodides. Furthermore, AISI 316 has a very high corrosion resistance – especially with regard to chlorides.
  • Heat exchanger with CDC coating
    Ideal for the application in especially reactive air environments. Due to the cathodic dip coating (CDC) the coating of the heat exchangers is resistant to solvents and corrosion as well as to acids and alkalis.
  • High-pressure fan
    For a greater volumetric flow the fan is available with a static pressure increase (200 Pa), which enables longer air transport distances e.g. when connecting the device to existing ducted air systems.
  • Defrosting below 0 °C
    To lower the dew point in particularly cold environments such as cold stores the operating temperature range of the DH 310 can be enhanced to between -0.5 °C and +42 °C.
For the application in particularly hygiene-sensitive areas the DH 310 is optionally also available with a stainless steel housing as per AISI 316
Can optionally also be supplied in a stainless steel housing
In addition to the free discharge of dry air into the room the rectangular duct connection also permits an integration into existing ventilation systems or the attachment of air transport hoses using the optionally available hose adapter.
Connection facility for duct systems or fan hoses

All operational settings can be made via the central control panel which has been recessed to protect the operating elements from impact and consequential maloperation.

The double-flow radial fan of the DH 310 impresses with a high efficiency level and simultaneously minimized energy consumption. Its EC motor automatically controls itself in accordance with the specified parameters and therefore consumes clearly less power than permanent motors of the same performance category.

The integrated MID-compliant energy consumption meter comes equipped with and additional service menu providing information for maintenance.

Owing to the condensate pump integrated as standard the condensate may also be discharged to a higher level instead of through a downward sloping drain. Simply fasten the discharge hose to the desired connection and activate the pump.

The control panel further accommodates the power button for the on-demand condensate pump and a DIN socket for external switchings to which e.g. an external hygrostat can be connected or facilities for remote switching of the DH 310.

For the direct attachment of air transport hoses to the dry air outlet of the DH 310 we offer an optionally available hose adapter which can be mounted to the rectangular duct connection of the device.

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.
