Benefits

CXV

Low Energy Consumption z

Evaporative Cooling Equipment minimizes the energy consumption of the entire system because it provides lower operating temperatures. The owner saves money while conserving natural resources and reducing environmental impact.

z

Evaporative Condensers provide lower condensing temperatures and can offer significant horsepower savings over conventional air-cooled and water-cooled condensing systems.

z

CXV provides heat rejection at the lowest possible energy input and maintenance requirements via: - High efficiency, low kW axial fans - Patented combined flow technology, which reduces evaporation directly off the coil, minimizing the potential for scaling and fouling - Parallel flow of air and spray water, which eliminates scale-promoting dry spots - Multiple Fan Motor System: independent fan motor and drive assembly per fan, which allows for extra steps of capacity control.

Easy Maintenance z

Access - Hinged access doors provide easy access to the unit interior. In addition, all CXV models are provided with an internal walkway as standard. An internal walkway is available as an option on CXV-D models.

z

Spacious Interior – Provides easy access to the cold water basin, drift eliminators, fan drive system and condensing coil.

Combined Inlet Shield Technology Combined Inlet shields prevent biological growth from sunlight, act as a filter for air borne impurities and debris and eliminate water splash out.

CXV

Remote Sump Execution The use of an auxiliary sump within a heated space is the most satisfactory way to protect sump water from freezing. When the circulating pump is shut off, all the water in the water distribution, in suspension and in the sump will drain freely to the auxiliary sump. Note: For detailed information on the calculation of the remote sump tank, please refer to the section "Technical Resources, Selection of Remote Sump Tank".

Combined Inlet Shields

Removable Bundled Fill (only CXVmodels) For installations where it is necessary or recommended to remove the wet deck surface for more thorough cleaning and disinfection, removable bundled fill is available. The fill bundles can be easily lifted and handled by one person and therefore provide a simple and secure method of removing and installing. The bundles can be dismantled and sheet by sheet can be removed for inspection and cleaning of both sides. After cleaning the sheets can be rebundled and re-installed.

General Notes CXV Models 1. Standard refrigerant in- and outlet connection sizes are ND100. Consult your local BAC Balticare representative for size and location. Refrigerant connections are standard bevelled for welding. 2. Unit height is indicative, for precise value refer to certified print. 3. Shipping/operating weights indicated are for units without accessories such as sound attenuators, discharge hoods, etc. Consult factory certified prints to obtain weight additions and the heaviest section to be lifted. Operating weight shown in the tables is based on total unit weight, weight of refrigerant operating charge and basin filled to overflow level.

4. Refrigerant charge listed is R717 operating charge. To determine operating charge of R22 refrigerants, multiply by: 1,93. For R134A, multiply by: 1,98. 5. The standard right hand arrangement as shown has the horizontal air inlet side on the right when facing the coil connection side. Left hand can be furnished by special order. Water and refrigerant connections are always located on the opposite ends of the unit. 6. All CXV models will be shipped in two sections. 7. Units have standard Low Noise fans. For units with Whisper Quiet fans a “W” is added at the end of the model name.
