Multistack Chillers utilize innovative technologies to create modular chiller systems that provide elegant solutions for the difficult problems of today's marketplace. Multistack offers both Air-Cooled Packaged Chillers and Water-Cooled Chillers.
Airstack Air-Cooled Packaged Chillers
Scroll Chiller Modules
Modules are available in 10-, 15-, 20-, 30- and 60-ton packages, each with dual scroll tandem compressor sets. Modules
may be mix-matched and combined to form chillers from 10- to 600-tons. Units are available with high-static condenser fans for ducted applications.
Medical Chillers
Modules are available in 3-, 5-, 71/2 -, and 10-ton packages, utilizing advanced digital scroll compressor technology. This completely packaged chiller is designed specifically for dedicated cooling of sensitive medical equipment and includes integrated pumps and tanks.
Airstack Accessory Modules
A complete line of accessory modules is available for integration into the Packaged Air-Cooled Chiller. These accessory modules include packaged pumping modules, free-cooling modules, and expansion-tank/glycol feeder modules.
Water-Cooled Condensing Units
All of Multistack's Packaged Water- Cooled Chillers are available in a Water-Cooled Condensing Unit version. Most required refrigerant specialties are factory mounted within the module. Units are designed to interconnect to a fieldsupplied evaporator.
Air Cooled Split-System Chillers
All of Multistack's Packaged Water-Cooled Chillers are available in an Airstack Split- System Air-Cooled version. All required refrigerant specialties (for standard ambient) are factory mounted within the indoor module. Multistack provides matching remote air-cooled condensers. Chiller systems are available from 20- to 720-tons.
Multistack Air-Cooled Chillers
Water-Cooled Chillers
Packaged Scroll Modules
Modules are available in 20-, 30-, 50-, and 70-ton packages, each with dual independent scroll compressors. Modules may be mix-matched and combined to form chillers from 20- to 600-tons utilizing environmentally friendly R-410A.
Large Packaged Screw Modules
Modules are available in 70-, 90- and 130-ton packages, each with a single twin-screw compressor. Modules may be mix-matched and combined to form chillers from 70- to 1,040-tons.
Centrifugal Chiller Modules
Centrifugal chiller modules are available in 80-ton packages utilizing the industry's most advanced magneticbearing, oil-free compressor technology. The compressor shaft levitates in a near-frictionless magnetic field, eliminating metal-to-metal contact. An integral variable-frequency drive controls compressor speed and capacity to precisely match the load, creating the most efficient modular chiller ever devised. Modules utilize R-134A refrigerant and may be assembled to form chillers from 80- to 640-tons.
Environmentally Friendly Refrigerants
R-410A and R-134A
Refrigerant 410A and 134A are widely available, safe, and environmentally friendly refrigerants with no phase-out date. R-410A is available in virtually all Multistack systems with circuits of 35-tons or less. R-134A is available in machines with circuits larger than 35-tons.
Environmental Focus
In addition to providing products to deliver reliable comfort and low operating cost, Multistack's products can also reduce a businesses environmental footprint. We are committed to developing and manufacturing cooling and heating products that can eliminate fossil fuel consumption and operate on the refrigerants designed to protect the environment. Dedicated heat pump boilers, air-to-water heat pumps and efficiency improvements across our product line are the result of this focus.
