Standard Features |
Benefits |
Dual compressor / Dual circuit chillers |
Reliability; 75% of design capacity available if one compressor down |
Redundant CHW & CW pumps |
Reliability; ease of maintenance |
Variable Primary Flow design |
Energy efficiency; optimized to load; lower first cost |
Integrated component design |
Optimal efficiency of components built into design; not just "assembled" components |
VFD control system |
Optimizes plant efficiency though all load conditions; allows for Low Load and Continuous Economizer features |
Low Load Controller |
Reduces cycling of compressor; allows for continuous operation down to 3% of load |
Continuous Economizer Loop |
Automatically reduces load by any available "free cooling" tons until it can handle the entire load and shuts down the chiller |
Compact footprint |
Saves construction costs; allows for easy retrofit application |
Mounted cooling tower |
Reduces footprint and comes pre-wired and piped to minimize installation costs |
Integrated controls |
Maximum efficiency and integration of design components; easy interface with BAS |
Refrigerant detection and ventilation system |
Safety protection and alarm system meets all code requirements |
I beams for compressor removal |
Ease of maintenance in the event a compressor needs to be removed |
Interior service lights and outlets |
Convenience lighting and outlets available when inside the unit |
ETL labeled and U.L. listed |
Piece of mind and added safety; streamlines the installation and inspection process |
Single point electrical connection |
Reduces installation costs; easy installation to field mounted disconnect switch |
Diamond tread plate floor |
Prevents slipping if floor gets wet; easy to keep clean |
I beam base frame |
Structural integrity for crane movement; stable frame for pad or roof curb mounting |
Victaulic couplings |
Relieves stress of transport allowing some flex in piping; no welds to crack |
Fan coil for cooling interior |
Maintains equipment and space at a comfortable temperature (<80 degF) |
2" double wall acoustical enclosure |
Structural integrity; sound attenuation--very quiet operation |
Pitched roof design |
Keeps water from pooling on the roof |
Data Logger |
Facilitates troubleshooting in the event of an alarm |
Telelink modem |
Remote access and programming |
| Manual-Off-Auto Panel |
Ability to override any alarms and get unit operating in manual mode |
| Touch Pilot touch screen |
Graphical interface for information in unit |
| |
|
| Optional Features |
Benefits |
| Plate & frame heat exchanger |
Waterside economizing in drier climates; allows Continuous Economizing operation |
| Primary / Secondary configuration |
Adds primary pumps to the unit; application specific design; preference of some engineers |
| Chemical feed station |
Pre-piped outside the unit; requires mounting and chemical barrels (by others) |
| Centrifugal water separator |
Reduces CT maintenance by removing solids from basin |
| Dolphin Chem-free water treatment |
Environmental friendly CT maintenance w/o chemicals; guaranteed performance |
| 304S.S. tower sump |
Reduced scaling and maintenance of CT |
| Tower fan sound attenuator |
Reduces tower fan noise |
| Eye wash station |
Safety component; installed outside the unit |
| Compressor removal hoist |
Used to remove a compressor |
| Refrigerant alarm |
Required on most jobs |
| De-mounted cooling tower |
Separate CT frame; allows for easy tower installation; typical option for units larger than 300 tons |
| Extended service warranties |
|
| Comfort View Software |
Graphically monitor system components |
| CCN Web interface |
Internet access to view and/or modify set points (password security levels) |
