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

When a local Biodiesel company decided to grow their process, there were several capacity challenges that they faced. Thermal Products Inc. was consulted to help address the process cooling system utilized during the reclamation of methanol from the vegatable oil recycling process. We designed a cooling tower and pump skid from Advantage Engineering and condensers from API Heat Transfer's Plate Heat Exchanger and Shell and Tube Exchanger groups.
The collected vegetable oil waste from area commercial kitchens and food process plants is heated, broken down, and cleaned with an alcohol based fluid. One of the results of this process is the by-product, Methanol. Reclaiming methanol is both environmentally sound and cost effective. The cooling challenge was that both vegetable oil and methanol reach high temperatures of 260F during the process. Once separated, the methanol vapor must be condensed back to a liquid, stored, and readied for reuse.
Thermal Products designed and offered an Advantage Engineering 45 ton evaporative cooling tower to provide a top end of 85F cooling water to an API Heat Transfer Shell and Tube exchanger that was designed to condense the Methanol to an inital 100F. This was achieved by the steady year round 85F water temperature that the tower could provide to a pump tank station combination.
The Methanol at 100F still needed to be at a final temperature of 60F. Due to limitation of a cooling tower to provide 85F water during the summer months, a "trim" 15 ton water cooled chiller from Advantage Engineering, was provided to supply 50F chilled water to the API Heat Transfer plate and frame exchanger to reach the desired Methanol temperature of 60F.
With high energy costs being a real challenge to process plants and their ability to be competitve, Thermal Products designed a hydrid process cooling system to have the majority of the heat load handled by an inexpensive open cooling tower and pump skid system. Thermal Products then designed the "trim" cooling system for summer operation with the use of a small water cooled chiller.
Employing the provided hydrid process cooling system not only cut capital costs for the equipment, but the operation costs were much lower than they would have been if just employing a refrigerant chiller for the entire heat load.
An Evaporative Water Tower is an energy efficient way to dissipate heat from your process. It is common for people to think a chiller is needed anytime something needs to be cooled but we should do the exercise to find out if an evaporative tower can do the job. The major question is this… Can your process be cooled by 85F water? If unsure, check with operating personnel or the equipment manufacturer of the process. If the answer is yes, then you’re on the road to an efficient way to cool your process. We say 85F, because on average summer days, a properly sized evaporative water tower can provide cooling water at 85F and even lower during cooler times of the year. A Cooling Tower Ton is 15,000 btu’s of energy vs 12,000 btu’s for a refrigerant ton, making a cooling tower more efficient. An evaporative water tower that is placed on the roof or elevated by legs and bracing provides a self-draining method into an indoor pump tank station where its water is then pumped to your processes providing year round operation. Thermal Products can work with you on the few technical pieces of data needed to size one properly.
A Chiller and it’s terminology in the industrial world denotes below ambient cooling with fluid temperatures mainly between 40F to 60F to your process. Many processes truly need these colder temperatures in which the heat removal through refrigeration is achieved. Most process applications can circulate process water through a loop in the building that is kept cool by a refrigerant chiller.
This can be accomplished by installing either an “air cooled” or “water cooled” chiller. Air cooled chillers are most popular as they are easy to install and use. Both air & water cooled chillers can be placed outdoors or indoors. If placing an air cooled chiller indoors you need to be aware of the heat being rejected into your room. Thermal Products can assist you with that calculation.
Pump Tank Stations are an integral part of an evaporative water tower including tremendous thermal storage in the chiller process as well. Water has excellent characteristics to absorb heat quickly and then let it go. Incorporated in the use of an evaporative water tower means a large sum of 85F water in a 400 to 1500 gallon tank size retains this water while one or more pumps send this water to and from your process. It returns back warmer in many cases pre designed at 10 degrees higher. The same water mixes with a dedicated pump to the evaporative water tower, heat is removed in the tower or chiller, then is returned back to the tank.
While chillers, in most cases, have a smaller reserve of water on board, a pump tank station is used for “batch cooling”. You might have a process in which you only need to cool it a few times a day or maybe once a day such as quenching of parts. In this case, large amounts of cold water and a little chiller is the answer. Calculated properly a small chiller needs to only cool a large volume of water in a pump tank station. The chiller might, for example, have 4 hrs to cool a pump tank station, bring it down to 50F and await the next process. Once again, designed properly by Thermal Products this large volume of water might only raise 15 to 20 degrees higher, achievable for a chiller of moderate size.
