A place to learn about Multistack Modular Chiller Products. Multistack, Originators...Innovators...Never the Imitators!

Originators…
The modular water chiller was invented by Multistack. It started with a radically simple idea: water chillers made up of modules that could be brought into the equipment room one at a time, through standard doorways and down elevators, to form a fully integrated water chiller system. The modular chiller idea launched a revolution and transformed Multistack into a leader in the commercial water-chiller industry.

Innovators…
Multistack perfected the modular chiller and leads the industry in innovative and environmentally friendly modular solutions. Since founding in the late 1980’s, 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-410A.

Never the Imitators…
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.

Who Is Multistack?

Founders
In early 1989, three former Trane Company executives—Bill Bast, Dick Campbell and Monte Holman— partnered to form Multistack Inc., taking over the North American sales, marketing, engineering, and product support of an Australian-invented modular water chiller.

History
Throughout 1989 and the early 1990’s, Multistack LLC established an extensive North American distribution network, redesigned the Australian product for North American distribution, established a manufacturing process in West Salem, Wisconsin, and began a revolution in the commercial water chiller industry.

As with any new idea, skepticism was common. In a mature industry like cooling and refrigeration, new ideas are not accepted without being put to the test. But year after year, Multistack saw its sales grow at an annual rate in excess of 15 percent. In fact, in six of the last seven years Multistack has experienced annual growth in excess of 35 percent!

Since the early 90's, control of Multistack has shifted to succession management. Mr. Mark Platt and Mr. Charles Kenyon joined Multistack in 1995 and 1996 respectively and have been controlling the day-to-day operation of the business since that time. In June of 2002 Messrs. Platt and Kenyon, along with a small group of private investors successfully executed a Management Buyout of Multistack. This transaction insured the company’s independence and a continued focus on its primary market of modular water chillers.

Today, Multistack is touching the world in many ways most don’t realize. Our chillers are used by major US companies like CBS, Paramount Studios, PPG, Gillette, GE, Ford, GM, and many others. We provide the cooled water used to produce toothbrushes, to cool the crash test facility for a major US automobile manufacturer, to handle the critical cooling needs of the United States Department of State overseas, and recently secured a contract to provide critical cooling to the proving grounds for the US Global Missile Defense System (formerly SDI or “Star Wars”).

Modern Facility
In April 2006 Multistack took occupancy of its new 70,000 square foot facility in Sparta, Wisconsin. This new state-of-the-art facility combined all development, testing, manufacturing, and administration under one roof. In the winter of 2007, a major office expansion was completed. A major plant expansion was completed in July of 2008 that nearly doubled its manufacturing capacity. Today, Multistack occupies a total of 120,000 square feet and is the fastest growing chiller company in North America. We celebrated our 20th anniversary in 2009 and continue to grow at an astounding rate.

Multistack continues to distinguish itself by putting its customers first, by providing flexibility of design, and providing quick, on-time shipments – every time. In 2009 Multistack was the first modular chiller manufacturer anywhere to become AHRI certified and leads the industry with the most AHRI certified modular products.
