Our Software & E-Tools

We have a number of different software applications available to help you select and specify air distribution solutions more efficiently. All items, including those featured below, can be found under the "Software" menu.

K-SELECT: This program allows you to select and specify Krueger grilles, registers, diffusers, terminal units, and fan coil products.

K-HIT: This program allows you to select and specify Krueger chilled beams and displacent diffusers. Features include a room view with air distribution patterns to aid in the design of the space.

COMFORT TOOL: This program is based on the ASHRAE Comfort Standard (55-2004) and can help you determine the acceptable limits of temperature, airspeed, and humidity for building occupants in both mechanically and naturally conditioned spaces.

AHRI 885 CALCULATOR: Based on your inputs, this program will provide you with discharge, radiated, and room sound values. Features include graphical representations of data.

ROOM SOUND CALCULATOR: This program computes NC, RC, and dBA values from known room sound pressure levels. Features include graphical representation of data.

REVIT BIM BLOCKS: Krueger has a large library of blocks that can be downloaded individually or in groups.

AutoCAD FOOTPRINTS: Download all terminal unit files at once or individually, as needed.

Our History

1948 - Krueger is founded by Leo Krueger

Leo Krueger emigrated from Latvia, where he had been trained as a machinist and mechanic. After living in Detroit, MI for a period of time, he settled in Tucson, AZ, where he went to work for one of the largest sheet metal contractors in the area. He designed the tooling for a line of residential grilles for use with evaporative coolers, which was a regionally new product at that time.

After two years, Leo’s employer offered him the tooling and equipment used to make the residential products for $500. It was this investment that allowed him to start his own company out of his garage, then called Krueger Manufacturing Co.

1950's - Entrance into the Commercial Marketplace

Introduced in the late 1950’s, Leo Krueger’s first foray into the commercial market began with the predecessor of what is known today as the model 800 series grille. During that same time, the SH diffuser was released to the marketplace. Both products have remained incredibly popular in today’s engineering specifications.

1960's - First Test Lab & Performance Data Gathering

A new line of 4200/4500 series perforated diffusers were introduced in the mid 1960’s that were designed in part with the engineering department at the University of Arizona. It was during this time that Krueger began to establish credibility through the development of the first test lab and production of genuine product performance data.

Krueger went on to purchase Thermotank and soon introduced the Con-VolMatic (CVM), which was Krueger’s first terminal unit, featuring constant volume and variable temperature.

1970's - Defining Operating Room Air Distribution

Early in the 1970’s, Krueger developed the Sterilflo®, which is the only operating room particulate control system to have ever been tested and certified during live surgeries. As an advanced product for its time, it is still a leading air distribution solution for critical surgical spaces today.

Also developed in the 1970’s was the Con-Vol (CV), which was Krueger’s first variable air volume (VAV) terminal unit and predecessor of today’s series of LMH terminal units.

1980's - New Found Manufacturing Efficiencies

In 1984, through a joint operation of Krueger and TSI of Minneapolis, the Omni Directional Anemometer was invented. Omni probes used in labs today continue to be a direct descendent of this development and are the industry standard.

Throughout the 1980’s, Krueger continued to grow their product offering, introducing the Total Air Diffuser (TAD) in 1985, which was later featured in Krueger’s first electronic Product Catalog that same year.

After the acquisition in 1986 by Philips, Krueger enjoyed increased manufacturing efficiencies and investment capital, which was not only a springboard to additional brand growth, but allowed them to remodel their test lab two decades after its inception in 1989.

1990's - Investment for Expansion and Brand Visibility

Tomkins, a global engineering and manufacturing group in the United Kingdom, acquired Philips in 1990, placing Krueger under the care of Air System Components (ASC). With the additional support and resources available, Krueger was given the opportunity to renovate their lab and construct their first in-situ and critical rooms in 1996.

During the late 1990’s, Krueger released the DesignFlo®. This architectural linear slot diffuser still remains in high demand today with a wide variety of options.

2000's - Increase in Development & Product Breadth

As Krueger moved into the next millennia, they released several new products, beginning with the KQFS and KQFP in 2000, which were the quietest fan terminal units in the industry. In 2002, the Prism™ diffuser was introduced, allowing architects to coordinate air distribution with a building’s decor. Then in 2004, LineaHeat™ (now patented) for terminal units was launched as the only true proportional electronic heat option available in the marketplace. Towards the end of the decade in 2009, Krueger expanded their product offering with the CRFF fan filter unit.

2010's - The Evolution of Air Distribution

Beginning in 2010, Krueger embarked on a major evolution of their product portfolio, entering into new product segments, such as Chilled Beams and Displacement Ventilation. That same year, they introduced the environmentally friendly KLPS-D and KQFS-FA terminal units.

By late 2011, they added Fan Coils to their offering while underway with the relocation of their engineering department and development of a new state-of-the-art test lab and training facility from Tucson, AZ to Richardson, TX.

Formal agreements were solidified in late 2012 that dissolved Tomkins and created Air Distribution Technologies, Inc., (ADTI) under which ASC and its brands reside.

2020's - Joining the Johnson Controls Family of Brands

Krueger, as a part of ADTI, was acquired and sold by different Canadian investment organizations after 2012. In 2016, ADTI was acquired by Johnson Controls, a multi-billion dollar international company that offers the world's largest portfolio of building products, technologies, software, and services. Today, Krueger continues to establish their roots and grow within the Global Building Products division.
