EGRD Air Dryers

ELGi Global Refrigerated Air Dryers (EGRD) are suitable for all applications that require constant dew point. The EGRD Series air dryers provide the customer best overall value proposition with excellent performance. ELGi’s industrial air dryers are manufactured in compliance with applicable international standards (UL, CE, CRN) and designed as per the international quality standards.

ADVANTAGES OF ELGi REFRIGERATED AIR DRYERS?

High Reliability

The advanced design features and superior build quality of the EGRD air dryers ensure high reliability during operations. These air compressor air dryers are also equipped with internal thermal overload switch for enhanced product safety.

Ease of Maintenance

The metal access panels in the EGRD air dryers for compressors can be easily removed to offer immediate access to all parts of the dryer system. The advanced DCM24 controller also provides service warning in case the service time has expired or if there is a probe failure.

Superior Insulation

Every component of the refrigerant circuit which is in low pressure/cold side is insulated, to avoid condensation. The material used for insulation in the EGRD refrigerated air dryer is Antimicrobial Nitrile Rubber, which provides active protection against microbes such as bacteria and fungi/mould/mildew and promotes better air quality. This also results in Increased long term thermal efficiency and a lifelong built-in product anti-microbial protection.

Energy-Efficiency

The EGRD air dryers provide best-in-class power consumption. Various features are included to ensure superior energy efficiency, such as auto switching off the fan motors when not required. The operation of fan is decided by the condensing temperature or the condensing pressure.

Low Cost of Ownership

The EGRD refrigerated air dryers have the lowest pressure drop of 0.11 bar at rated capacity, that is 40% lower than average competition. This along with the best-in-class power consumption provides the low cost of ownership for the users.

Environmentally Friendly

ELGi EGRD compressor dryers use environmentally friendly R134a and R407C refrigerants that have zero Ozone Depletion Potential (ODP). The dryers also meet the F-Gas regulations and have one of the lowest Global Warming Potential (GWP).

HOW DO ELGi EGRD DRYERS WORK?
EXPERIENCE THE ELGi ADVANTAGE

ELGi is an air dryer manufacturer with over 60 years of experience in design and manufacture of air compressors and compressed air dryer systems.

BENEFITS OF EGRD AIR DRYERS FOR COMPRESSORS

High-efficiency copper-tubed aluminium finned condenser : The hot, high-pressure refrigerant enters the condenser of the air compressor air dryer in a gaseous state, gets cooled through the forced circulation of cold air using a fan, and flows to the capillary tube in a liquid state. The condenser fan switches off/reduces speed based on the condensing pressure & dryer temperature.

High-efficiency aluminium-plated heat exchangers : The air to air, and air to refrigerant heat exchanger design of the EGRD refrigerated air dryer ensures cross flow between coolant and hot air thus minimising pressure drop and maximising thermal efficiency. The heat exchanger in the air dryer is insulated with environment-friendly material for high degree of insulation and efficiency with minimum impact on the environment.

Pressure-operated, 100% modulating mechanical type hot gas bypass valves : The advanced bypass valves in the air dryer ensure quicker and reliable response to changes in load conditions, maintaining optimum dew point at any load conditions. The bypass valves also prevent freezing phenomenon in the heat exchangers of the compressor dryer and ensures smoother and reliable operation due to complete mechanical system.

Full-feature dryer controller with remote monitoring : The advanced DMC24 controller in the EGRD refrigerated air dryer displays pressure dew point temperature, condensing pressure, total operation hours, and hours until next service. The EGRD compressor dryer controller also provides a failure prevention alarm and service warning and can stop of compressor in conditions of low refrigerant pressure/high discharge temperature. It can also automatically stop or reduce fan speed according to the condensing pressure and dryer temperature.

High-quality build design : The refrigeration compressor is hermetically sealed for high energy-efficiency. This also reduces the vibration and reduces noise in the refrigerated air dryer. A refrigerant filter ensures the humidity that enters the refrigerant system during refrigerant replacement does not clog the system. High-quality copper tubes ensure that the refrigerant flows into the heat exchanger in the liquid state and reduced temperature.

Condensate-sensing drains : A level-sensing zero loss drain in the EGRD air dryer for compressor removes the condensate from the system with no air loss.

FREQUENTLY ASKED QUESTIONS (FAQs)

What are the different types of air dryers?

There are wide range of industrial air dryer for compressors. Desiccant air dryers and refrigerated air dryers are two different air compressor dryers types that are used for removing moisture from compressed air and operate on distinct principles. Desiccant air dryers use a desiccant material, typically a special type of drying agent like silica gel or activated alumina, to absorb moisture from the compressed air. Refrigerated air dryers or a heatless dryer works by cooling the compressed air to lower its dew point using refrigeration compressor, causing moisture to condense into liquid form.

What is the best air dryer for air compressor?

There are various types of industrial air dryers available. The choice of the air compressor dryer type that is best-suited for your needs depends on the specific requirements of the application, the desired level of air dryness, and energy efficiency considerations. There are different types of heatless dryers, cool air dryers and membrane dryers that can be selected based on the application.

Can you oversize a refrigerated air dryer to get lower pressure drop?

No, ELGi air dryers have the lowest pressure drop. In general, it is not recommended beyond a certain point to oversize as dryer could malfunction and consume higher power.

Does ELGi air dryer have on off control of condenser fan for energy saving?

Yes, automatic condenser fan on/off is available in ELGi air dryers for energy saving.

Do air compressor air dryers need ducting when installed in a compressor room where compressors are ducted?

Small size compressed air dryer systems (up to 10kW rating) do not need ducting as heat dissipated/heat load is less. For larger size, ducting can be done based on ventilation of room.

What is the meant by dew point and pressure dew point temperature of a compressed air dryer system?

The temperature at which water vapour in the air starts to condense or change from vapour to a liquid or a solid state in a compressor dryer is called its dew point. When the dew point is measured at elevated pressures more than atmospheric pressure, it is called pressure dew point.

What is the minimum load percentage required and minimum pressure required for an ELGi air dryer?

There is no minimum load percentage required, and the minimum pressure required is 4 bar for the dryer.

How do I know the air dryer price for an air dryer manufactured by ELGi?

ELGi’s industrial air dryers are available through the vast network of ELGi distributors across the world.
