Pedigree Ovens / The Pound Bakery

Althoff Industries installed a 1.7 Megawatt solar array that will produce 100% of the 200,000SF dog treat production facility’s electrical needs as well as offset over 1400 tons of greenhouse gases.

Designed by SimpleRay, the bone and paw are easily visible to the 90,000+ flights per year that go into and out of O’Hare airport.

Field Heating Systems

Althoff Industries is a skilled veteran in the installation of hydronic field heating systems. We have completed field heating projects for practice and game fields in the US and Canada for teams in the National Football League (NFL), Major League Baseball (MLB) and Major League Soccer (MLS)

Clean Room

Althoff Industries, in the course of reviewing the basis of design for a new clean room for a healthcare products manufacturer, was able to incorporate recirculation fans to maintain the FDA required air changes per hour while reducing the designed HVAC capacity by over 60%.

This resulted in significant savings for the client on both the initial equipment and subsequent energy consumption.


You won’t find a firm in Chicagoland with more experience in heating and cooling than Althoff Industries, Inc.. We’re the top contractor to handle HVAC needs for:

  • Computer rooms and data centers
  • Clean rooms
  • Environmental quality control
  • All air-handling needs (rooftop units, make-up air units, VAV)

We’re known for using the latest technologies and methods to find cost-effective solutions that balance temperature, humidity, and energy consumption. We create custom components for specialty fabrications, customized duct systems, exhaust systems for kitchens, lab hoods, and more. Trust us to handle your industrial HVAC needs on time and on budget: we work on all stages of the process, from design and engineering through installation.

Process Piping

Whatever industrial piping services you need, no matter how unusual, we can handle: installation, maintenance, inspection, retrofitting, upgrading. We are specialists in process piping and have the in-house skills and experience necessary to get any job done to exact client specifications. What we offer clients is a level of peace of mind that the service was completed correctly and with full attention to all details.


In addition to process piping, Althoff Industries, Inc. is top in the field for all aspects of industrial plumbing. Engineers, architects, and building owners know they can call us for the best work, done on time and meeting the most demanding specifications. Our team works on projects of all sizes: water storage, filtering, distribution, ADA compliance updates, relining, backflow certification, and complete new facility services.


We can meet any demand for industrial electrical systems, offering solutions rather than quick repairs or patch-ups. We engineer and execute electrical services for new construction, relocation and expansion, lighting retrofits and upgrades, installation of fiber optics and data cabling, thermal imaging, and industrial electrical equipment installation. No matter your goals, we’ll achieve them on time, under budget, and with an attention to customized detail that’s unsurpassed in the area. You can always count on our 24/7/365 support services.

Building Controls

Our constant dedication to the latest in technology is perhaps most important in our work with building automation systems (BAS). Modern industrial facilities require BAS for energy management and overall effectiveness, and we provide some of the field’s most innovative building control solutions. We have extensive experience with designing, installing, upgrading, and maintaining BAS and take a multi-disciplinary approach to finding the best outcomes for clients. This is one of the most customized services for industrial facilities, and our commitment to continual research, training, and factory certification allows us to deliver the ideal BAS customization for your needs.
