Industrial condenser dryer DH 310
Versatile dehumidifier for continuous commercial and industrial dry keeping applications
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:
- Dry keeping of production facilities and storerooms with specific humidity requirements
- Corrosion protection in engine rooms of ships and optimum storage atmosphere during transport for goods that are sensitive to moisture
- Dehumidification of water processing facilities and pump stations to prevent condensate formation on pipes and pumps
- Prevention of corrosion in electrical control centres, boiler plants, turbines and pipe systems in power plants
- Humidity regulation in computer centres, control rooms etc.
- Climate conditioning in the field of shipbuilding, on shipyards or in cargo areas
- Humidity regulation in the food industry, for example in the dairy or in confectionery production
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.
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.
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.
