We have multiple branches located throughout the Upper Midwest. We have distributors and branches all over Wisconsin and Northern Illinois, including: Milwaukee, Pewaukee, Green Bay, Madison, Wausau, Eau Claire, Gurnee, and Woodridge. Contact your local or nearest Zorn representative for service, support, equipment needs, or other requests.

Upgrading your compressed air system can help you save money in a variety of ways. For example, your existing compressor controls may not be as efficient as possible, so we can explore other control methods such as variable speed drive technology to increase energy efficiency long-term. We could also look into adding compressed air storage to allow your compressor to run less frequently due to the assistance of buffer storage. We offer data logging and auditing services to provide a clearer picture of your compressed air system that allows us to identify weaknesses or deficiencies in your compressed air system, so that we can make recommendations for increased efficiency.

The type of compressor you have will ultimately determine how often service is recommended.  The most common type of compressor we service, rotary screw compressors, typically have a recommended 2000-hour maintenance interval.  Reach out to your Zorn rep to discuss how often your compressor runs and your company’s hours of operation to determine the maintenance interval that’s right for you.

We size air compressors around the volume and pressure requirements of the facility in question.  In many instances, we’re working off an existing system, which allows us a starting point in future sizing.  In other instances, we can calculate air requirements around the specific equipment running in a given facility and sizing around those parameters.  To go even further, we can data log an existing compressor system by installing loggers on a compressor control panel that actively tracks real time amp draw of the compressor against system pressure to calculate what kind of capacity the compressor is running at in order to maintain system pressure.  This information will allow us to size a new compressor as accurately as possible.

We sell the following air compressor brands:

• Quincy
• Gardner Denver
• Ingersoll Rand
• Powerex
• Rogers KNW Series
• Hydrovane
• Aerzen
• Hycomp
• Sauer

We sell both new and used equipment (when available).

For a standard rotary screw installation with best practices, we normally have the compressor, followed by an air line pre-filter to help protect the air dryer, followed by an air dryer for moisture removal, followed by a post-filter for oil removal downstream, followed by an air receiver for storage before exiting to the plant. Many rotary screw systems <30 HP come in an “airstation” configuration that has the compressor mounted to an air receiver with an integrated air dyer to preserve floor space. Regardless, compressor into dryer and filter with a tank somewhere before or after the compressor is almost always ideal.

We offer air compressors and related parts and equipment, including:

• Air compressors
• Vacuum pumps & blowers
• Air dryers & filters
• Oil & water condensate separators
• Panels & sequencers
• Flow controllers
• Fluid coolers & chillers
• Nitrogen generators
• Filters
• Valves
• Piping
• Lubricants

and more.

Yes, we offer leak detection services.

Zorn Trained Technician will conduct a survey using ultrasonic detection equipment to evaluate for compressed air leaks.

The survey process includes:

• Identifying
• Tagging
• Repairing
• Tracking
• Logging
• Verifying

The inspection analyzes your leak loss and estimates current annual costs of any leaks, based on your current energy costs. After assessing the results, a trained technician can repair tagged leaks in accessible areas such as:

• Pipe fittings
• Poly tubing
• Quick connects
• Hose connections
• Filter regulator lubricators
• Auto drains

We do perform oil quality sampling as part of our air quality testing (AQT) process.  This process allows us to test and monitor the particulate, water, and oil content (PWO) in a customer’s compressed air, as well as microbials.  This testing can help develop air quality standards for customers or even to stay in line with safe quality food (SQF) compliance.

We don't do "contracts," we do custom-tailored management agreements. Our no-contract-required system means you can opt in, opt out, and then back in at any time.

We recognize the necessity for continuous and proper maintenance throughout your system’s life. Each maintenance agreement is a custom-tailored agreement that is based off of your annual running hours, equipment configuration and environment, and your unique system needs. We will continually track hours accumulated on your system throughout the years and service it accordingly and you only pay for the maintenance that is required.

We offer 24/7 emergency service. We also offer customized maintenance agreements tailored to your company's needs.

We provide maintenance agreements, not contracts, so it’s entirely performance based.  When we expect a customer to be due for their next maintenance call, we’ll give them a call or send an email to let them know what kind of PM is expected and we can work on scheduling at that time.  If the customer would like us to come in sooner or later, at whatever interval they prefer, or not at all, no problem.  In some instances, we’ll work on contracts for customers if needed, but typically we just run with the maintenance agreement, which works really well.

Both sales and service departments will get back to you same-day and emergencies are always a priority. At this time we will also schedule either a technician or sales on-site visit to address your needs. For true service emergencies, a technician will be to your site that day, as soon as possible. We have a 24/7 emergency line incase these scenarios happen outside of regular business hours.

All of our local branch locations are equipped to perform service! Service calls will be directed to the closest branch to your business: Pewaukee, Madison, Green Bay, Eau Claire, Wausau, Gurnee, or Woodridge.
