Description
ELGi Airmate EGRD 1100 Refrigerated Air Dryer
The ELGi Airmate EGRD 1100 is a refrigerated air dryer built to reduce moisture in compressed air for general industrial applications. By condensing and separating water, refrigerated drying helps prevent corrosion, line freezing, and contamination in downstream tools, controls, and equipment.
The EGRD platform uses a fully modulating hot‑gas bypass valve to respond to changing load conditions and maintain a stable pressure dew point. A controller with a 3‑digit display provides dew point visibility, operating hour tracking, service indication, and drain test functionality for easier day‑to‑day monitoring.
Key Features
- Constant dew point drying: Refrigerated drying supports consistent moisture control for most plant air systems.
- 100% modulating hot‑gas bypass: Helps maintain dew point across varying loads and reduces freeze‑up risk in the heat exchanger.
- Operator visibility: 3‑digit controller display shows pressure dew point and operating/service status for faster troubleshooting.
- Efficient heat exchange: Cross‑flow heat exchanger design helps reduce pressure drop while improving thermal efficiency.
- Energy‑efficient refrigeration package: Hermetically sealed compressor design targets low noise and vibration.
- System protection ready: Pairs with a matching pre‑filter (AF 1177P) to help protect the dryer and downstream equipment.

Benefits
- Reduces moisture‑driven downtime: Helps prevent water carryover that can cause sticking valves and tool wear.
- Protects air distribution: Drier air helps limit internal pipe corrosion and water hammer in lines.
- Right‑sized capacity: 1000 scfm capacity supports properly sized compressor packages and point‑of‑use loads.
- Installation flexibility: Air Cooled design and 460 V / 60 Hz / 3 Phase supply support common industrial installs.
Installation & Application Notes
- Rated capacity is typically stated at nominal conditions (100°F ambient, 100°F inlet air, 100 psig) unless otherwise noted.
- Install upstream filtration to remove particulates and oil aerosols; this helps protect the dryer’s heat exchanger and improves downstream air quality.
- Recommended upstream pre‑filter model: AF 1177P (P/N B003308170068) where specified in the system design.
- Connect condensate drain piping to an appropriate collection/management system and verify drain operation during commissioning.
- Allow service clearance for condenser cleaning, electrical access, and routine inspection.
The ELGi Airmate EGRD 1100 is designed for reliable refrigerated drying where stable moisture control and easy monitoring are priorities.
Frequently Asked Questions
ELGi Airmate EGRD 1100 Refrigerated Air Dryer
▶️ Question: What does a 41°F pressure dew point mean for my system?
Answer: A 41°F pressure dew point indicates the moisture level the dryer is designed to deliver under rated conditions. In practical terms, it helps reduce condensation in piping and at points of use in most indoor plant environments.
▶️ Question: Why does the dryer use a hot‑gas bypass valve?
Answer: A fully modulating hot‑gas bypass valve helps the refrigeration system respond to changing air demand. This supports stable dew point control and helps reduce the chance of evaporator freeze‑up during low‑load operation.
▶️ Question: How do I choose the right dryer size?
Answer: Start with your true compressed air demand at operating pressure and temperature. Choose a dryer with rated flow capacity at or above that demand (1000 scfm for this model), then apply correction factors if your inlet conditions differ from nominal.
▶️ Question: Do I need a pre‑filter ahead of the dryer?
Answer: A pre‑filter is strongly recommended to keep solids and oil aerosols from entering the dryer. Cleaner inlet air helps reduce pressure drop increase, protects the heat exchanger, and supports longer service intervals.
▶️ Question: What maintenance items should I plan for?
Answer: Plan periodic condenser cleaning, verification of drain operation, and filter element changes (where installed). Maintenance frequency depends on ambient conditions, inlet air quality, and run hours.
