Model AWG 60 is a 60 ton refrigeration unit, which closely resembles the DPI 4-6 machine. This model has two independent refrigeration circuits utilizing two 15 ton compressors in tandem per independent circuit. Low temperature (33F) or low humidity (30%) will also initiate temporary system shutdown and are programmable to not unduly waste power. When temperature or humidity improves, the machine will automatically restart. The system is designed to initiate startup for each of the two independent staged systems on a timed basis. If a power failure occurs, the system will start-up automatically when the power returns. The system is configured with all the safety over temperature and over current protection. As an option it can have internet monitoring and in many cases be reprogrammed remotely. Individual compressor failure will only shutdown 50% of the entire system. Only a blower motor failure will cause complete system shut down.

The AWG 60 is programmed to read dew point at any temperature and automatically adjust air flow to maintain optimal operation to produce water. High temperature and humidity demand a high Cubic Foot per Minute (CFM) air flow while low temperature and humidity require lower CFM air flow. Patented technology allows automatic de-icing when the evaporator goes below freezing. At approximately 55 - 60°F outside ambient air or 32°F evaporator coil fin temperature, both circuits continue to operate down to 33°F outside ambient air utilizing Air to Water Technologies aka The Water Company's patented hot-gas by-pass system to avoid icing. No other refrigeration technology allows for the independent operation in this temperature range.

Operating Ambient Temperatures:33°F to 110°F (Changes are programmable within these temperatures)
Compressors & Peripherals:Four 15 ton Scroll Trane Compressors, Heatcraft Coils, Standard Accumulators and Receivers, and Parker/Sporlin Valves
Power
  • 460 VAC, 60 Hz 3 phase - 85 amps low,
    140 amps high temperatures - kWh: 57.5 to 95.8
  • 400 VAC, 50 Hz 3 phase - 80 amps low,
    135 amps high temperatures - kWh: 47 to 79.4
  • 380 VAC, 50 Hz 3 phase - 86 amps low,
    141 amps high temperatures - kWh: 48 to 78.8
  • 220 VAC, 50 HZ 3 phase - 145 amps low,
    244 amps high temperatures - kWh: 47 to 78.9
On-Site Monitoring:
  1. Compressor head pressure
  2. Pressure drop across the inlet air filters
  3. Temperature of the suction gas
  4. Ambient air temperature and humidity
  5. Dew point of the ambient air
  6. Total gallons produced
Remote Monitoring (extra fees apply):With this option all of the above components can be monitored remotely via the internet. A static IP address is required. With remote monitoring emails can be sent out to alert of a warning or alarm level for any safety. Data such as gallons produced and dew point trended and can be down loaded from the local controller to a PC via the internet. If necessary the local controller can be modified or completely reprogrammed remotely via the internet. The programming engineer can optimize the logic if necessary to produce the maximum water.
General Controller Features:
  1. Monitor head pressure and suction temperature of each circuit. Airflow can be adjusted to keep both within specifications.
  2. Prove airflow via the Delta Pressure (DP) transducer across the inlet air filters. This same sensor can detect a high pressure drop across the filters and email a notification to clean (if remote monitoring option is purchased).
  3. Suction temperatures are kept above freezing by use of the patented hot gas by-pass system.
  4. Dew point will be calculated and used to optimize the water production. Dew point will also be used to determine if the machine should be shut down due to no moisture in the air.
