Application Spotlight: Batch Process Water Heating

Thermal Products Inc was asked to design a Shell & Tube Heat Exchanger within a certain footprint as it needed to fit within our customer’s packaged heating system. We offered to design and build an all 316 Stainless Steel Shell & Tube Heat Exchanger, but our customer requested 304 Stainless Steel Shell & Tube Heat Exchanger instead. Our customer also requested the tube side connections of our shell & tube heat exchanger to be Tri Clamp connections for ease of cleaning the heat exchanger.

The design parameters for the project were to heat 300 gallons of process water from 60 degrees Celsius to 80 degrees Celsius in 15 minutes or less. Our customer’s control package needed to maintain tight temperature control with a +/- .5 degrees Celsius discharge temperature variance for their exacting process downstream. The circulating process water flow rate for each batch will be 120 gallons per minute (GPM)

The 304 Stainless Steel Shell & Tube Heat Exchanger was designed to be a 08024, Type BEU with 304 stainless steel tubes and a 2-pass tube side design. The thermal duty was achieved using 387 lb/hr of steam and was built to ASME Code Section 8, division 1 and TEMA C.

Thermal Products sales and design engineers can design a fully customized heat exchanger to your exacting specifications or an "off the shelf" design for quick shipment and installation.  Thermal Products can supply the heat exchanger alone or integrate it into a skidded package with controls, valves and pump(s) on a skid enabling a more "plug and play" design, significantly reducing our customers installation costs.

Thermal Products appreciates a challenge and was asked to heat and maintain temperature in a caustic acid process tank. Thermal Products designed dimpled surface heat transfer plates in 316 stainless steel for a regional chemical plant.

Most chemical processing plants have several tanks containing caustic acids for various processes within the process plant. Most of these tanks are glass lined, requiring indirect heating or cooling of the contents. This makes Thermal Products dimpled surface heat transfer plates an ideal solution for these processes.

The original heat transfer plates installed many years ago had developed leaks with little design information to refer to for a redesign. This required Thermal Products to custom design our heat transfer plates to fit existing tank and connection penetrations. Installing Heat Transfer paste between the outer tank wall and inner wall of the heat transfer plate is critical for not only a affixing the plate to the tank, but to increase the heat transfer coefficient between heat transfer plate media and contents of the process tank.

With thermal design points from the customer, site visits and photos, Thermal Products designed and created engineered installation drawings for our customer to review.

From the time of our customer's approval of manufacturing drawings, Thermal Products shipped the heat transfer plates to the customer within 3 weeks, fitting another customer requirement.

Clamp on Heat Transfer Plates are effective and efficient. Thermal Products also can offer our dimpled surface heat transfer plate in the applications below

  • Bayonet Heaters for tanks
  • Heat Recovery 
  • Immersion Plates
