- supplying Ebac Dehumidifiers since 2002
Dehumidification is possible using two possible principles, Condensation with refrigeration style dehumidifiers and Adsorption with desiccant dehumidifiers. Desiccant dehumidifiers perform exceptionally well when used in cooler climates, or when a low dew-point, deep drying or low humidity levels are required. Since desiccant dehumidifiers do not produce water, they will work effectively down to sub zero temperatures. We offer a range of Commercial Ebac Desiccant Dehumidifiers including models DD200, DD300, DD400.
Depending on the environment Ebac Desiccant Dehumidifiers can lower humidity to 4%rh. We also supply a Remote Humidistat for accurate control.
Their operation is simplistic yet extremely effective and reliable. Air (Process Air) is drawn into the dehumidifier, where is passes over a wheel impregnated with Silica Gel. As the air passes over this wheel, any moisture present in the air, is absorbed into the Silica Gel wheel before leaving the dehumidifier as warm dry air. The Silica Gel wheel is continually, slowly rotating, typically at three revolutions per hour. As the wheel rotates a small portion passes through the regeneration segment. During this phase a second air stream (Regeneration Air) is heated to a high temperature before passing over the wheel. Any moisture present in the wheel is released into this air stream, this hot wet air is then exhausted outside the area being dried.
Ducting - Circular spigots on the machines allow for easy connection of flexible or rigid ducting. Ducting should be as short as possible for maximum efficiency.
Manual / Automatic control is a standard feature within the DD range of desiccant dehumidifiers, and a remote humidistat can quickly and easily be connected for automatic operation and control The Ebac range of DD desiccant dehumidifiers are all manufactured from a high grade stainless steel, ensuring a rust free product when used in the most sever of applications The spigot connectors allow quick and easy installation All models incorporate a high efficiency patented PPS Rotor. This design incorporates a 82% active Silica Gel to ensure optimum performance over the equipments wide operating range of environments. All desiccant rotors supplied by EIPL are washable, and designed for high performance / long life.
Explanation of inlets & outlets on the DD200, 300 & 400
The simple installation is to only have one hose and that is to get rid of the hot wet air externally. However if you want to increase efficiency (this is an option on the DD400), in other words to have a quicker rate of dehumidification and therefore reduce running costs you could fit a hose to the regeneration air inlet which requires the adaptor plate. In doing this it does mean cutting/drilling 2 holes through a wall, one to take the 70 or 102mm wet air out hose depending on model and another to take the 127mm inlet hose. This is a matter of choice only on the DD400 as the regeneration air inlet for external air into the unit is not essential but an option.
In mounting the humidistat I would recommend that it needs to be located away from the dry air air-stream leaving the dehumidifier otherwise it will give a false room humidity level.
