Time flies when you’re having fun – it is all too easy to allow certain routine tasks to slip past your radar.  There are many reasons why your plant’s Piping & Instrumentation Diagram (P&ID) may no longer be up to date, but don’t worry, KOSS can help if you have neither the time nor the inclination to revise your Plant P&ID.  Maybe your sanitary process piping no longer appears to be so sanitary…  Whether you want your piping mapped out, brought up to code, re-sized, or re-routed – Koss Industrial’s talented Road Crew & Engineering Team can help you on-site.

“KOSS-Quality” – Innovation You Can Trust.

There’s “high-quality”, and then there’s “KOSS-Quality” – superior products & services.  Utilizing our skilled Engineering Team’s Services to update your Plant P&ID provides an excellent opportunity to go over any future plans or concepts (for future projects, you’ll know that we’re familiar with your plant).  We provide custom solutions that complement individual applications.  By having a KOSS team member update your Plant P&ID you also benefit from having another set of eyes on your process layout and plant design.  We love it when we’re given the opportunity to help customer processes experience higher-efficiencies with lower complexity & maintenance.

Koss Industrial, Inc. offers a broad range of services beyond Process/Mechanical Design & Engineering.  Consider our Road Crew – we’ve been working on-site at customer facilities from the very beginning.  Did you know that KOSS worked in local customer plants before we had our own manufacturing plant?  Customer-centric,  Koss Industrial was founded by brothers Joe & John Koss, who started out working on-site in Wisconsin cheese plants – so you can trust that KOSS understands the idiosyncrasies of the Dairy Industry.

Discover Smaller Footprint Production Lines (For Custom Block & Barrel Handling)

Need to reduce the size of your blocks & barrels, without sacrificing all of your floor space?  KOSS Sanitary, Custom Grinders can help with that.  Other lines can be bulky, involving multiple steps and machines…KOSS Grinders can extrude barrels, directly into cookers or onto conveyors if desired.

Sick of harping?

Sick of harping on the same old issues when cutting your cheese barrels?  Cutting barrels can pose an enormous safety risk.  All of those moving parts can be an accident waiting to happen, and securing the area surrounding cutting machinery takes up a significant amount of space.  Instead of cutting product to reduce size, try a KOSS Grinder, or view some of our equipment tests in our Green Bay, WI manufacturing plant.  We’ve tested a variety of cheeses, in Grinders ranging from lab- to production-sized.  View some of our videos in the playlist below.  Can you see your product in a KOSS Custom Grinder?

Free up floor space!

Koss Industrial, Inc. believes your space is valuable, so why waste it?  Our production lines are custom designed to suit your space – whether you have limited floor space, or a height restriction, KOSS will find a way if there’s one to be found.

Sized to suit you, the biggest constraint on time for KOSS Grinders is load (feed) time…the standard “speed problem” is that our machines grind faster than they can be loaded.

Strong & sanitary, innovation is the name of our game – call us at 1.800.844.6261 and find out more about the Custom Grinder KOSS would recommend for your application!

Need A Sanitary Trolley? KOSS Does Custom Overhead Conveyors.


High quality, Overhead Conveyor Systems by Koss Industrial, Inc. are available in many styles & configurations…because they’re custom.  KOSS even designs & fabricates Sanitary Stainless Steel Trolley / Track Systems!

Design – Movement

Custom Overhead Conveyor Trolleys are available in styles that either:

  • Trolleys Ride Atop a track (sanitary designs possible, as the trolley wheels glide atop a diagonally mounted square tube), or
  • Trolleys Ride Inside a track (non-sanitary design, trolley wheels glide inside a c-channel / rectangular enclosed track).

Direction – Route

We’re able to help you convey your materials overhead along the necessary path.

  • Straight Track
  • Curved Track

Motion – Power

  • Free Systems (manual, moving the trolley along the track by hand)
  • Power Systems (mechanical, not moving the trolley along the track by hand)
    • Fully Automated:  improves efficiency and drastically reduces the risks of human error (automation helps reduce the risk of potential injury by minimizing exposure/human contact)
    • Power Assisted:  reduces physical strain on personnel, allowing the operator to safely manually handle a larger and/or heavier load (via mechanical assistance)

Get Trolley/Track Systems On Other Machines

Integrate-able Feature

KOSS even integrates custom Trolley/Track Systems as optional “adder” features for other equipment and systems!

Why integrate a Trolley/Track System?  Safety first!  Reduce physical strain on personnel.  Help eliminate the risk of an employee dropping a heavy, sharp, or otherwise-potentially-hazardous item.  Plus, an integrated trolley is typically beneficial to preserving the longevity of the machine it is on.

What would a Trolley/Track System get integrated onto?  Across COP Tanks (possibly with integrated hoist/lifting mechanism), onto Grinders as a swinging Trolley Arm (hinged to allow safe face plate disassembly for auger removal), …there are innumerable ways to integrate .

When should I consider integrating a Trolley/Track System?  Integrate it anywhere you need to move anything that is either heavy and/or awkward to either grasp or maneuver. Stay safer by limiting and controlling movement with trolley/track systems.

Start Conveying Your Sanitary Product SAFER

Now that it’s installed, are you worried your New Sanitary Conveyor  isn’t as compliant as you ordered?  It happens:  the design & fabrication company assured you they’d build what you needed, but they didn’t have the industry experience – their “sanitary” conveyor’s weld-quality doesn’t come close to matching your other equipment. Their conveyor has crevices and corners that you know won’t stay clean; perhaps you even find areas that aren’t drainable… you ordered sanitary, but didn’t receive it. Consider calling Koss Industrial, Inc. for help, we can save non-compliant components, equipment & systems. Whether your non-compliant issue requires a touch-up, refinishing, or a complete re-design, KOSS can help.

Hot Water Sets – Safer Thermal Energy Systems

Regulate & maintain temperature with KOSS Hot Water Sets – wall-mounted and skidded designs are fully customizable. Koss Industrial, Inc. designs and manufactures a Hot Water Set to best complement your application and unique specifications.  We also provide high quality Process Piping Services, along with many others!

Why Hot Water?

Hot water offers advantages such as precise temperature control with even heat distribution, eliminating hot spots and providing quality control and ease of cleaning. Not only is the system easier to regulate, but a Hot Water Set is also easier to operate than a steam system.

Functioning at lower pressure, a KOSS Hot Water Set doesn’t require special jacketing and provides a safer environment (by not needing high-pressure steam runs throughout the plant).  Regulating & maintaining temperature is a breeze with Hot Water Sets – KOSS’ hot water systems are fabricated to USDA & WDA Sanitary Standards and are constructed from durable stainless steel.  We can design/fabricate hot water sets to meet your specific needs and requirements.

Hot Water Offers:

  • Precise Temperature Control
  • Even Heat Distribution
    -eliminates hot spots
    -quality control/ease of cleaning
  • Lower Pressure
    -doesn’t require special jacketing
  • A Safer Environment
    -as opposed to having high pressure steam runs throughout the plant

Hot Water Sets - skidded design

When would I NOT use Hot Water Sets?  Heat transfer in a steam system is higher than a hot water system, so you wouldn’t consider using hot water if your process includes UHT treatment.  Find out more about KOSS Culinary Steam and Heating & Cooling solutions online, or call 1.800.844.6261.

What Are My Options?

We provide solutions to meet and exceed standards.  Some examples of available options for Hot Water Systems include:

  • Various Material Finishes
  • Controls (various systems)
  • Skid or Wall Mounted
    • Layout / Design
