PART 2 - PRODUCTS
2.01 ACCEPTABLE MANUFACTURERS
A. Multistack LLC B. (Approved Equal)
All wiring utilizes spring capture technology to prevent loose connections or wires from falling out. Dedicated Ethernet communication at a communication rate of 50 microseconds to all compressors and I/O. MagLev hubs feature dedicated inputs for high pressure switch, low pressure switch, dedicated compressor interlocks, and dedicated compressor communications. This allows for each compressor to be handled independently by itself without affecting the rest of the system. Software Controller shall control one (1) refrigerant circuit. HMI interface is user definable including: points list, tag names, and functions without special software. With this feature, end user can scale on all inputs and outputs, change what controls it, change the functionality, the name of it etc. Control system can be field reconfigured through HMI to remap I/O to change functionality on the fly. This allows for customized integration into the end users system. Control system can trend graph up to two (2) years of data, without overwriting or decreasing data acquisition time. Control System features easy to use web interface. This allows the user to do anything remotely that could be done on site. Advanced trend graphing available on the market. Over 100 data points are recorded in five (5) second intervals. Data can be analyzed with zoom feature. Data stored on separate 32 GB drive. Trend graph images can be exported. Trend graphs can be exported to CSV files as well. Advanced Fault Logging featuring calendar capability for ease of use. Data can be recalled up to two (2) years. Data can be sorted by alarm type, time stamp, or compressor. Color coded data: Green data means good, yellow means alarm, red means fault or off. Controller logs when user makes any type of change. Controller has onboard maintenance log to store system information. Controller offers real time capacity and efficiency data. Native BAS Interfaces included with controller are: Modbus RTU Modbus TCP/IP Optional BAS Interfaces thru interface module include: BAC Net IP BACNET MSTP Lonworks BAS interface dashboard shown on HMI. This allows the user to view what data is being written to the BAS system. Also shows if there is an error, last com, and how many times the data was sent or received. Control system uses proprietary optimization logic to perform accurate energy balance on all systems for maximum system performance. Control System features an optimum start function to ensure initial lift is always made. This prevents nuisance check valve flutter and compressor faults. E. Chiller Power 1. Chiller shall have a unit mounted through the door disconnect. Chiller shall also include a master breaker. 2. Unit shall also have through the door disconnects for the compressor and for the fans. This will allow power to be separately shut off to either or both components without the need to open the access door. 3. All enclosures shall be built to NEMA 3R specifications, ETL listed, fully vented, louvered and feature cooling fans controlled by FlexSys Lite for maximum energy efficiency.

Originators
Multistack invented the modular water chiller. It started with a radically simple idea: chiller modules that could be brought into the equipment room one at a time, through standard doorways and down elevators, to form a fully integrated chiller system. The idea launched a revolution and transformed Multistack into a leader in the commercial water-chiller industry. Multistack perfected the modular chiller and leads the industry in innovative and environmentally friendly modular solutions. Since founding in the late 1980s, Multistack has engineered, manufactured, and distributed an impressive array of modular air conditioning firsts: the first on-board strainer, the first modular automatic blow-down device, the first modular chiller for variable flow, the first modular chiller-heater (heat pump), the first modular heat-recovery chiller, the first modular air-to-water heat pump, the first modular chiller to utilize MagLev compressor technology, and the first modular chiller to utilize R-134a. Multistack sets the standard in the industry for superior customer service, fast and on time shipment, superior product quality, and new product development. Our pioneering leadership in environmental issues is well documented. If you want the best, be sure to specify the original Multistack.
