Hot stuff, coming through!

Why do you need a Shell & Tube U-Tube Heat Exchanger by Koss Industrial?

  • Sized for efficiency
  • Custom configured to individual applications
  • Longer lifespan with superior construction and corrosion resistance
  • ASME certified, models >6″ diameter (8, 10, 12 inch U-Tube Heat Exchangers operating above 15 psig mawp will be ASME stamped)
  • Built in-house in our Green Bay, WI facility

KOSS custom U-Tube Heat Exchangers for heating or cooling (ASME certification available!) provide superior corrosion resistance, their construction results in less weld fatigue (providing a longer lifespan than straight Shell & Tube models). Excellent longevity – tubes are suspended from one end, better allowing expansion and contraction with temperature fluctuations.

Configure a custom U-Tube HX today – 316L stainless steel construction, clamp or weld body connections, various end connections, optional insulation (with SS welded covering), 4″ or 6″ body diameters (8″, 10″, 12″ dia. available), body lengths from 2-20 ft!

For a longer lasting solution, call Koss Industrial, Inc. today 1-800-844-6261!

Notes for all Heat Exchangers:

We recommend placing a Strainer prior to the Heat Exchanger (to prevent blockages & optimize performance, check out our Wedge Wire Strainers).

Always avoid hydraulic shock.

Ensure your Heat Exchanger is sized & configured for your application (consider current & future operating parameters, to ensure long-lasting optimal performance).

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
  • Different Styles of Expansion Tanks
  • Insulation
  • Stainless Motors
  • Heat Exchangers
    • -ASME U-Tube
    • -8, 10, 12″ U-Tube Heat Exchangers operating above 15 psig mawp will be ASME stamped

But honestly?  Virtually anything is your option.  KOSS is uniquely qualified to provide custom sanitary solutions because we have a strong history serving cheesemakers (since 1978) and many others throughout the sanitary industries (we now serve applications from industrial to pharmaceutical).Hot Water Set - skidded design

Shell and Tube Heat Exchanger

Simply put, a shell and tube heat exchanger is used to cool fluids on a large scale, such as in an oil refinery. The device consists of a pressure shell that contains tubes. Fluid is directed around the tubes using baffles.

To function, two fluids of different temperatures are fed into the exchanger. One flows through the tubes and the other flows outside the pressure shell. As the second fluid passes over the tubes the heat of the two liquids are exchanged. Tubes come in one-pass and two-pass forms.

Hot Water Sets

Regulating & maintaining temperature is a breeze with Hot Water Sets!

  • Precise Temperature Control
  • Even Heat Distribution (eliminates hot spots;  offers 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)

Koss Industrial’s hot water sets are designed & fabricated to USDA & WDA Sanitary Standards and are constructed from durable stainless. Heat Exchanger has 3A symbol. We design & fabricate hot water sets to meet the customer’s unique needs.

Available Options include: various material finishes, controls for hot water set, skid/wall mounting, different styles of expansion tanks, insulation, heat exchangers (ASME or U-Tube; 8, 10, 12 in. U-Tube Heat Exchangers operating above 15 psig mawp will be ASME stamped)

Koss Heat Exchangers

  • Plate
  • Scraped Surface
  • Double Tube
  • Triple Tube
  • U-Tube (4-12″) *150psi standard

Our ASME certified 304 & 316L U-Tube Heat Exchangers provide superior corrosion resistance over carbon steel. Also, the U-Tubes’ construction results in less weld fatigue, giving it a longer lifespan than straight shell & tube models.

What is a Heat Exchanger?

What is a Heat Exchanger?

Simply put, a heat exchanger is a device that facilitates the transfer of heat from one medium to another in an efficient way. Heat exchangers can be used to move heat between either devices that are touching or those that aren’t even in the same room. This technology is utilized in everything from heating and refrigeration to petroleum refinement and sewage treatment. If you’re having trouble grasping the concept, the radiator in your car is a good example of a heat exchanger.

There are several different types of heat exchangers, with shell and tube being one of the most common. Comprised of a series of tubes, these heat exchangers contain multiple fluids which are used to transfer heat and regulate temperatures. Another one of the more common designs is the plate heat exchanger. These units are made of several plates that are connected together with a small space left in-between each one. Thanks to advancements in technology, these more simplistic heat exchangers are now viable options for HVAC, refrigeration and other common uses.
