The Airmate EGRD Series 200-500 models are designed for Australian conditions and built to increase performance while maintaining the same benefits as single phase versions such as energy efficiency, high reliability and low cost of ownership.
From the food and beverage industry to the printing, plastics, injection molding and chemical industries, wherever compressed air needs to be dried to a low dew point, the ELGi Airmate EGRD range of refrigeration dryers offers the solution.
Running energy efficient compressed air equipment can go a long way in minimizing energy and operating costs. With the Airmate EGRD series of non-circulating refrigeration dryers, customers can be assured of optimal efficiency through a variety of design features.
This includes a sophisticated controller that ensures optimal efficiency by automatically reducing fan speed or stopping fans based on condensing pressure and dryer temperature.
A highly efficient rotary compressor delivers best-in-class specific energy consumption, further contributing to the overall high energy efficiency of these dryers, while a new generation ELGi-based heat exchanger minimizes pressure drop and maximizes thermal efficiency.
These non-circulating dryers are really up to the task with small footprint and constant loading. For maximum efficiency, the 3-stage cold storage heat exchange system allows the units to be turned on and off as needed.
The efficient and ultra-compact heat exchanger is also capable of operating efficiently at high ambient temperatures, making it ideal for Australian conditions.
Energy savings are also achieved by including a zero-loss drain that only drains condensate and no air is lost.
Airmate EGRD 200 to 500 series models include hermetic and energy efficient fixed speed rotary compressors. Key features such as suction separator silencers, internal protection devices, reverse phase protection devices in three-phase versions and run capacitors enhance the overall reliability of these compressors.
There are a number of additional design features that also contribute to the overall high reliability of these dryers, including a hot gas bypass valve to prevent freezing in the heat exchanger, the use of high quality copper capillaries, drains with liquid level sensors and insulation. Each pipe, many safety devices and many fail-safe controller functions.
ELGi specializes in the construction of energy efficient compressed air installations that ensure efficient energy consumption and lower energy costs. While customers benefit from reduced energy costs, ELGi also enables end users to reduce their carbon footprint and reduce their overall environmental impact.
The EGRD series is F-gas compliant and uses ozone-friendly R-134a or R-407c gases, both of which have zero ozone depletion potential (ODP).
Models of the Airmate EGRD series are easy to maintain. The access panel can be easily removed for instant access to all parts of the system. Moreover, all maintenance alarms are clearly displayed on the controller.
The Airmate EGRD range of dehumidifiers meet the highest standards of safety and reliability and are designed and manufactured in accordance with international standards (UL, CE and CRN).
Energy efficient, extremely reliable and competitively priced, the Airmate EGRD series of non-circulating refrigeration air dryers offer customers a low total cost of ownership. Availability of Australia’s most popular models in stock ensures fast order processing.
The entire Airmate EGRD range provides flow rates from 10 to 2900 cfm (0.28 to 75 m3/min) and is suitable for all applications requiring a constant dew point.
