The globally patented ATMOS Water Production System, integrated with the Caterpillar Power System, is a fully autonomous, mobile, and scalable atmospheric water generator that can produce large quantities of potable water in various climatic conditions. The system has been designed to simultaneously provide 35 ekW of auxiliary electrical power to further support field operations when utility or alternate external power sources are not available. The unit is highly adaptable and can also be integrated with renewable energy sources.
ATMOS has been specifically designed for rapid deployment in support of humanitarian aid, disaster response, contingency operations, and temporary environments where mobility and sustainability are critical drivers for mission success.

Two Models - Non-Powered or Integrated Power Units
The technology comes with or without an integrated power system. Depending on the application, and the clients requirements, the system can be configured to operate from a commercial power source or it can be configured with an integrated Caterpillar Power System. The non-powered unit is ideal for applications where mobility is not a primary concern and where the technology will be permanently installed. The non-powered unit is also idealy suited for rooftop applications providing distributed water resources without the need for expensive infrastructure investments to support drinking water needs.
The unit is composed of the following components and sub- assemblies that will be discussed in more detail in the following sections:

• Desiccant Regeneration
• Water Collection and Delivery
• Siemens Controls & Automation
• PROFINET Communication Protocol
Electrical Power System - (Powered System Only)
• Caterpillar Prime Rated Diesel Generator Set
• Caterpillar Service Entrance Rated Automatic Transfer Switch
• Customer Auxiliary Power Output
• Commercial Power Input
• Exhaust Heat Recovery
• Fuel Supply
Water Production System Overview
The Water Production System uses the thermodynamic principles of mechanical vapor compression in a traditional refrigeration cycle to create a cold surface in the form of an evaporator coil. The process condenses suspended water vapor into liquid as warm, humid air passes over the evaporator coils. The condensation, or water production capacity of the system, is significantly enhanced with the addition of a desiccant dehydration package. The dehydration technology allows for the extraction of large quantities of moisture from the air, drawing it into the desiccant structure as ambient air passes through three quarters of the surface area of the wheel. The dehydration process operates in a continuous cycle of moisture collection and regeneration. By applying heat in a separate air flow across the remaining one quarter of the wheels surface area, the captured moisture is released, and the process continues. The dehydration package effectively concentrates the moisture available for condensation and greatly improves the machines overall performance. The refrigeration systems evaporator coil is placed directly at the output of the dehydration systems regeneration air stream, where hot, humid air is passed over it and the suspended water vapor is condensed into potable water. This allows the machine to operate in climatic conditions where traditional evaporative technologies fail to perform.
Water Collection System Overview
Condensate is collected from the evaporator in the Evaporator Catch Basin. As warm moist air from the desiccant regeneration output is passed over the evaporator coils, the air is cooled and forced to dew point. The water vapor changes state from vapor to liquid and falls directly into the catch basin.

Water Filtration System Overview
The water supply system incorporates a two-stage water filter and an ultraviolet light to maintain water purity. When water is called for from the main storage tank, it passes through a 5-micron poly-spun sediment filter, an activated charcoal filter and then through an Ultraviolet (UV) disinfection chamber which destroys 99.9% of harmful pathogens, viruses and bacteria as an added precaution. Potable water is provided on demand using parallel constant pressure pumps for a maximum flow rate of 9 GPM. The system can be set up to run continuiously, supplying potable water to an external storage tank, or the system will cycle on and off based on the level of the onboard storage capacity. Once the main storage tank is full the water production stops until the tank level is reduced.
Electrical Power System Overview - (Powered System Only)
The electrical power system consists of the following components and subassemblies:
1. Caterpillar 158 ekW Prime Rated Generator set 60 HZ, 480 VAC or 50 HZ, 380 VAC
2. Caterpillar Service Entrance Rated Automatic Transfer Switch - 400 Amp, 4 Pole, NEMA 3R
3. Utility Power Input – 400 Amp
4. 50 KVA, 480VAC Delta to 208/120 VAC Wye Transformer (not required for 50 HZ models)
5. 40 KVA power connection point for customer power use
6. 2800-gallon UL 142 double wall diesel fuel storage tank -Accomodates a 14 day run time before refueling
The ATMOS units power system is designed to work on a primary electrical input from an alternate power source to the utility side of the automatic transfer switch with the generator set in standby. However, the unit will operate on generator set only in the absence or failure of the primary electrical power source.
