With Multistack, you can add capacity next week, next month, or next year – with no cost penalty and no extra hassle. Not sure what your total building load will work out to? Multistack’s scalable design lets you be conservative today without limiting your choices tomorrow. Planning to grow your operation in the future? No need to blow your budget with the capacity you don’t need right away. Install what you need and incorporate new modules when the timing is right!
N+1 redundancy in a conventional system usually entails the installation of a second chiller of equal capacity or three chillers at 50% capacity. Multistack’s modular design means that we can achieve the same level of redundancy at a much lower cost. A single backup module is all it takes to provide the critical protection you need to ensure continuity in the event of an interruption. An important consideration in modular redundancy is having controls sophisticated enough to avoid the loss of cooling even if the master module fails; we’ve got that covered too with our “Fail-To-Run Mode” controls.
Multistack was originally designed as a solution for problem chiller change-outs, which required costly and cumbersome dismantling and reassembly. Our modular approach means that new equipment can be delivered and the chiller built module by module. They can easily fit through doorways and into elevators and can even be installed around obsolete equipment if necessary. A space-efficient Multistack module can provide as much as 70 tons in as little as 9 square feet.
Because Multistack modular systems are more straightforward in their design than conventional chiller systems, they are generally easier and more economical to service. Modular units require no oil changes and no eddy current analysis. Simply keep the water clean and treated – and your job is done!
Multistack modular chillers are inherently quieter than conventional systems and, if necessary, we can use a variety of techniques to attenuate sound levels, including specially selected compressors and our trademark panel system. Less noise makes Multistack the perfect choice for critical medical and business applications, as well as discerning homeowners.
Multistack modular chillers are virtually always compliant with ASHRAE 15 and CSA B52 standards, which means you can do without auxiliary ventilation, monitoring, and SCBA equipment. The result? Big savings in terms of cost and installation time, not to mention an operational advantage when it comes to obtaining LEED certification.
