• 30-, 40-, 50-, or 60-ton modules available, with a minimum of three modules needed for multi-pipe operation. Therefore, system cooling capacity ranges from 90 to 480 tons and system heating capacity ranges from 1350 to 7200 MBh.
• Any module can operate in either cooling mode, heating mode, or simultaneous heating and cooling mode to meet real-time system demands.
• Six-pipe design features three independent loops, eliminating the need for extra heat exchangers and pumps and reducing the overall system volume of glycol and/or chemical treatment.
• Year-round system efficiency enhancement of chilled water and hot water loops by eliminating glycol mixing.
• Compact module size fits through standard doors and elevators for ease of rigging into tight equipment rooms.
• While in simultaneous heating and cooling mode, combined heating and cooling efficiencies up to 28 EER can be achieved.
• Can provide up to 135°F hot water, depending on source water temperatures.

Employing multi-pipe technology in systems

The most recognizable benefit of this multi-pipe technology is its ability to serve both the chilled-water and hot-water needs of a building simultaneously, which can allow for the design of highly-flexible thermal distribution systems. And the third heat exchanger allows for the three water loops to be completely independent, which eliminates the need for intermediate heat exchangers and extra pumps, minimizes the use of glycol and/or chemical treatment agents, and easily allows for the addition of supplemental equipment to one or more of the loops (e.g., a chiller on the chilled-water loop, a boiler or air-source heat pump on the hot-water loop, or a cooling tower or fluid cooler on the geothermal loop).

In addition, several multi-pipe units can be assembled together, forming a multi-pipe bank, to provide even greater flexibility since each circuit can operate in different modes, maximizing overall system efficiency.
