MULTISTACK MODULES

Multistack is not just about Modular Chillers--2009 brought the introduction of full-size Flooded Units

•Flooded Units available in 90-540 tons•Built to order in wide or tall designs

Theory of Modular Chillers

•Multiple smaller chillers connected in parallel allow array to meet building demands at peak times, but shut down modules when demand is lower. Modules use screw, scroll and centrifugal compressors

•Modular systems can easily be expanded for future building growth

•Redundancy is built-in. No need for a back-up chiller system when you have multiple compressors in parallel

•Installation is easy—individual units fit through office doorways and on elevators. No need for a crane or demolition

•Small footprint, low sound signature, AHRAE 15 compliance and more

•Dedicated Heat Recovery Chillers and Water-to-Water Heat Pumps integrate into arrays

Aero Thermal Air-to-Water Heat Pump

•Three Times Cost Savings Versus Natural Gas•Economically Friendly Upgrade For Two-Pipe Systems•Available in 10-, 15-, 20- and 30-Ton Modules•Cost Reduction By Eliminating Well Drilling

• Minimal refrigerant charge is safer for the environment and less

costly.

• Significantly quieter operation than a full-sized chiller.

• Oil-free refrigerant system means that oil cannot make its way onto

the heat transfer surfaces and degenerate the efficiency of the

system.

• Required electrical startup current for MagLev compressor is just 2

amps versus a full size compressor requiring 500-600 amps.

• A MagLev compressor’s weight is one-third of what a conventional

compressor of similar capacity would be. It requires significantly less

material and energy to manufacture a MagLev compressor, adding

positively to carbon footprint reduction process.

Magnetic Levitation (MagLev) Compressor Highlights

The heart of a Multistack

MagLev Chiller is the

Magnetic Levitation High

Speed Compressor. Capable

of spinning up to 40,000 rpm,

the Multistack control system

allows the compressor to

offer maximum efficiency at

almost any level of building

demand.

Two stage impeller offers exceptional part load efficiency
