Why the need for a Dehumidifier?

Dehumidifiers are required wherever there is a need to lower the humidity level to prevent corrosion, mould growth and condensation or maintain a low humidity condition during manufacture, packaging or storing of hygroscopic products.

Methods of Dehumidification

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. 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.

Why Choose EIPL?

EIPL is Europe’s leading manufacturer of dehumidifiers and is a name you can rely on. No matter how extreme the conditions EIPL’s efficiency copes comfortably even at the coldest temperatures.

Every dehumidifier is designed for efficiency and ruggedness, and built to last. The popularity of EIP Ltd’s dehumidifiers with the plant hire trade speaks for their reliability, portability and outstanding durability

DD700

The DD700 desiccant dehumidifier is an upright, compact design, which makes it easily accommodated within space restricted areas. The unit incorporates a PTC Heater ensuring maximum drying is immediately reached, and constantly maintained while the unit is running. The DD700 incorporates two EC fans with variable speed allowing the unit to be easily installed and commissioned in a wide range of applications.

An electronic thermostat allows and fully variable EC fans, allows the user to select the desired drying preference , ie High Efficiency, Deep Drying, or High Extraction.

The following table provides an example of capacities

27°C 60% - EXAMPLE SETTINGS
High Extraction High Efficency Deep Drying
Process Airflow (m3/hr) 530 412 294
Regen Airflow (m3/hr) 118 94 118
Regen Temperature Rise (K) 110 90 110
Extraction (l/d) 231 184 205
Dry Air Off (%) 18 18 8

Facility for an external humidistat allows the humidity level to be maintained at a preset condition. The EIPL range of desiccant dehumidifiers incorporate a rotors with a 82% active Silica Gel, thereby ensuring optimum performance over the equipments wide operating range
