Superheated refrigerant vapor enters the inlet header connections. Heat from the refrigerant dissipates through the coil tubes surface and out to the fins. The adiabatic air pre-cooling system involves fully wetting a fibrous pad located on the air-on side of the coil. Ambient air is drawn through the adiabatic pre-cooling pads by the fans located on top of the unit. The air saturates as it passes through the adiabatic pad, decreasing the ambient dry bulb temperature to within a few degrees of the ambient wet bulb temperature. This new air temperature is referred to as the depressed dry bulb. The pre-cooled air is then drawn through the tube and fin surface, providing a substantial increase in heat rejection capability. Heat from the refrigerant transfers to the air which is then discharged to the atmosphere. Cooled CO2 Gas exits the unit through the outlet connections.
Adiabatic Pre-cooling System
- Wetted pads can be utilized for pre-cooling entering air, resulting in greater energy savings, and increased capacity, with minimal water use
- Great for high ambient dry bulb climates or high temperature applications
- Once-through design
- No water treatment required
- No cold water basin or pump
- No drift
Reduced or Eliminated Water Consumption
Compared to traditional evaporative systems, the eco-Air series will either eliminate or dramatically reduce water consumption. Adiabatic models only use water when the ambient conditions and load require it. Reducing water consumption also reduces the ongoing expenses related with the cooling equipment such as purchasing, treating, and disposing of water. When the eco-Air adiabatic models are used in conjunction with the EVAPCO controls package, water conservation is maximized based on proprietary PLC logic.
Scaling, corrosion, and water born bacteria concerns are minimized or eliminated with dry and adiabatic cooling equipment. The eco-Air Series reduces the maintenance traditionally associated with fully evaporative systems. The eco-Air adiabatic condenser is designed as a once through system, meaning it has no pump and no basin to hold water, which further reduces the time required for maintenance. Additionally, the adiabatic pads filter the air before reaching the coil, limiting the exposure of dirt and debris to the tube and fin heat transfer surface. Both NEMA and EC motor options require zero routine maintenance. There are no bearings to grease, belts to adjust, or fans to pitch and balance.
Advanced Motor Technology
Available with Electronically Commutated (EC) or NEMA fan motor designs.
The motors on the eco-Air series are pre-wired at the factory to UL standards, reducing costs associated with field wiring. As standard, all units are wired to a common terminal box. Adding the EVAPCO controls package allows for both single point power supply and complete capacity control.
- Premium efficient direct drive
- Zero maintenance sealed bearings
- VFD ready
- Severe Duty
EC motors are the latest development in energy savings and speed control.
The high efficiency wing tip fans operate up to 3 dB less than conventional blade fans with improved part speed energy consumption.
- Zero maintenance
- Integrated speed control
Superior Stainless Steel Technology
- Constructed with high-grade Type 304L stainless steel tubing as standard
- Meets ASME B31.5 refrigerant piping code
- Available in 5/8-inch OD
Through the use of computational fluid dynamics (CFD) modeling software, finite element heat transfer analysis, and proprietary coil performance calculation methods, EVAPCO engineers have identified significant design elements to improve the finned coil performance. The extensive computer modeling has been refined and verified through coil performance evaluation in EVAPCO's state of the art research laboratories.
