Engine Generator cooling encompasses many options and methods. Typically, you'll find and engine radiator mounted on the engine frame rails or mounted remotely, with custom designed piping running back to the engine inlet and outlet. Depending on the engine and fuel burned, we can design jacket-water cooling, charge-air aftercooling, fuel cooling for your application. The cooling of an engine generator can be designed in a multitude of ways and setups.
The most economical cooling method is the "on engine" package, meaning the jacket water and aftercooler loop are cooled in a stacked core radiator assembly directly in front of the engine. Stacked core simply means, two cores, one behind the other. Another option is to have two cores side-by-side if the fan is having a hard time getting to the required static pressure across the cores.
Many applications that Thermal Products is involved with require the radiator to be in an entirely different location from the engine that is in the basement of a building. This requires custom piping runs between the remote radiator and engine. This arrangement can increase the head pressure on after coolers at the engine and on the engine jacket water loop. A typical radiator, aftercooler and engine, have a maximum pressure rating of 20-30 psi depending on design. Thermal Products can design into the cooling package intermediate plate & frame heat exchangers, that can remove the over pressurization risk to the equipment. In these scenarios the engine room will contain the equipment below:
Thermal Products, with our partners at API Basco, API Schmidt Bretten, IEA Radiators and FloFab Pumps, know that every project is different and can design the right cooling package for each project.
Our Scott Robinson had a recent application requiring a retrofit of an existing aluminum aftercooler (above) to two shell and tube aftercoolers (below) designed with stainless steel tubes for use with cooling tower water. Thermal Products designed an API Basco Pipeline Aftercooler or "PLAC" heat exchanger with custom tube side connections. The PLAC includes a floating back-end, allowing the tube bundle room to expand and contract, as needed.
The original aluminum Aftercooler had failed. When the engine was not in use, the treated cooling water was stagnant in the aftercooler. Over a period of time it simply corroded the aluminum welds, which lead to leaking.

Allows troubleshooting and isolation of a failed heating element.
Construction utilizes alternating half baffles spaced closely to cause increased flow velocity across the heating elements to allow better heat transfer from the elements to the fluid.
Pickle and Passivate
A chemical treatment in nitric acid can be performed to remove free iron from the outer surface of stainless steel for applications sensitive to contaminants.
Is a process similar to plating using cathode and anode reactions but material is removed rather than added to the heater surfaces in order to provide a clean and bright finish. This is very common with the pharmaceutical, biotech and food industries.

When speaking of Shell & Tube Exchangers, we tend to break them into "standard" and "custom" shell and tube exchangers. When we talk of tolerances of flow nozzles and support locations, those manufacturers that belong to TEMA (Tubular Exchanger Manufacturers Association) are expected to build each heat exchangers to within those accepted tolerance called out in TEMA.
See link below for TEMA Tolerances brochure.
Having published tolerances is most important for both the customer and the manufacturer, especially when speaking of "custom" heat exchangers as they are built to a fabrication drawing, without the use of a manufacturing "jig" or "fixture". Without the use of a jig or fixture, the skilled welder relies on measuring tools, which is fairly precise to the naked eye, but when measured exactly, the dimensions will not exact each time that part is manufactured. Building shell & tube exchangers with nozzle tolerances of +/- ¼” don’t tend to be an issue for process plant or system integrator customer’s as long as it is not more than the noted tolerance. In that instance it would need to be corrected, especially, for a TEMA Shop.
“Standard” heat exchangers tend to be built for OEM customers that rely on exacting dimensions for each delivery of the same shell & tube exchanger. In order to maintain quality assurance of each unit, the use of a jig or fixture to assist the skilled welder is a must. This will ensure each and every part, that is welded together, to make a shell & tube exchanger will have the very same dimension each time it is made. This allows customers to use a Thermal Products heat exchanger, with precision and speed in their product.
Having shell & tube exchanger's built to precise measurements is also import when looking to replace a heat exchanger in kind. In this case a Drop In Replacement tube bundle or complete heat exchanger is easiest for plant maintenance personal, hospital or school facility engineers, to install. It assures them that they will not need to make any required piping modifications on either the tube side or shell side.
Thermal Products offers Drop in Replacement heat exchanger and tube bundles for a wide range of heat exchanger manufactures. In most cases, Thermal Products will have the needed equipment to manufacturer a NEW heat exchanger or tube bundle that will fit right into place of the old heat exchanger you are removing. If we don’t, we will advise you during the quoting phase and include freight, in our proposal, for you to ship your old heat exchanger to us for duplicating.
If your heat exchanger is custom and can’t ship it to our facility for duplicating, but have a fabrication drawing, we can offer and build a NEW heat exchanger to your fabrication drawing. Please see our latest Drop In Replacement heat exchanger shipment below.
A New England Food company approached Thermal Products, Scott Robinson and our partner Advantage Engineering to assist them in designing a new process cooling system to cool a new low protein food being manufactured and then packaged.
At first review the (3) process cooling loads were deemed to be in the neighborhood of 100 tons total, depending on product batch temperatures. The initial design fell well above the customers budget for this project and forced us to review other avenues.
During the site visit, Thermal Product’s Scott Robinson, noted that the incoming city water temperature was within a temperature range to handle two of the three processes and recommended using the city water to send to the existing Plate and Frame heat exchangers that were isolating the cooling water from the process food, affording Thermal Products and Advantage Engineering to offer a revised proposal to handle 80% less cooling load. This not only reduces the capital costs of the chiller, substantially, but also lowered the operating costs significantly from what was originally thought.
Scott determined the remaining third process, did require 6.5 gpm of 36°F cooling water to be supplied prompting a revised proposal for a 20 Ton Advantage Engineering Air Cooled Chiller Model OACS-20 with a close approach Plate and Frame exchanger, again to isolate a 30% Propylene Glycol and Water mixture from water heading to an existing heat exchanger with process food on the other side. Scott needed to “de-rate” the chiller to the 9.75 ton load thereby needing 20 tons. The industry design standard for chillers has been a base design of 50°F chilled water temperature @ 95°F ambient temperature. When a lower cooling temperature is required, as Scott did in this application, a higher nominal ton capacity is needed to reach 36°F. The final chiller included some of the equipment below.
• Air Cooled Condensed R407c refrigerant circuit
• Scroll compressors with hot gas bypass capacity control
• Crankcase heater for cold start-ups
• Discharge check valve
• Brazed Plate Heat Exchanger as the evaporator
• 3HP process pump
• NEMA 4 Control Cabinet
• Advantage Proprietary MI Microprocessor control instrument
• Plate and Frame Heat Exchanger, shipped loose for installation indoors
Thermal Products was able to further assist our customer’s tight delivery needs by doing a small customization of a stock chiller in order to have the chiller onsite in Massachusetts in 1 week from order.
The next step Scott says is to consider storing the approximately 10,000 gallons of elevated hot discharge water used daily by trimming those BTU’s off in one large insulated poly tank.
“I have a design in the works to recirculate and cool daily water by preventing it from costly one time use then down the drain”.
“Q3 and Q4 is the timeframe to look at this”

Titanium TEMA Type AET ready for Shipment
Thermal Products was approached by a chemical company to design an Acetic Acid heater using 450 Thermal Oil. Heating Acetic Acid to a precise process temperature is key in the manufacturing insulated boxes.
Thermal Products designed a TEMA Type AET with a titanium tube side, meaning titanium tubes, titanium baffles and bundle supports, titanium tube sheets, titanium channel head, titanium reversing bonnet and titanium tube side connections.
A TEMA Type AET, is designed with a front channel head with channel cover, which enables the tube side of the heat exchanger to be cleaned without breaking or removing any of the piping. See figure "A" below.
The backend or rear bonnet was designed with a pull through floating head. This design takes into account thermal expansion and the ability to have a straight tube design with a removeable tube bundle. See Figure "T" above.
If you have an application that would require higher alloy materials, contact Thermal Products via phone, email, website inquiry form or chat feature on our website.
A local distributor was looking for three replacement tube bundles for Thrush Heat Exchanger Model S1848(2). Thermal Products offered our exact duplicate tube bundle Model TBU-18-48-2 with .049 wall copper tubes.

Above is a before and after picture of an old, tired heat exchanger and a new drop in replacement shell & tube exchanger that Thermal Products Inc designed and supplied as a drop in replacement heat exchanger to replace a modified Taco “E” BEU series heat exchanger. After meeting with the customer, a local state government, Thermal Products was able to offer one of our “Drop In Replacement” Heat Exchangers so piping changes would NOT be necessary. All critical center line dimensions were held.
Thermal Products offered a TPI-BEU-26-84-2, which is a 26” diameter shell, 84” tube length U-tube bundle, 2 pass tube side arrangement for steam to water application. We offered an all carbon steel constructed shell and head with ¾”, .049 wall copper tubes. The heat exchanger was built to ASME Code and stamped for 150 PSIG @ 375F. Higher temperature and pressure available upon request.
Although we supplied standard materials of carbon steel and copper tubing, Thermal Products, can readily supply Stainless steel shells and heads and stainless steel tubing, Cupro-Nickel tubing, admiralty tubing, Hastelloy, Titanium, AL-6XN among more.
If your shell and head or bonnet are in good condition, we can simply offer a replacement tube bundle instead. Replacing your tube bundle only with one of Thermal Products quality Drop In Replacement Tube bundles would make your project far less difficult and time consuming. In most cases, a Thermal Products replacement tube bundle comes with a .049 tube wall thickness, when most OEM tube bundles are supplied with .035 wall tubing, making your Thermal Products tube bundle more forgiving to tube side erosion from particulate in your water. Simply call your local Thermal Products office with your heat exchanger model number or picture of your heat exchanger nameplate and we’ll provide a quote to you, in most cases, the same day. All Thermal Products tube bundles come with gaskets.
All of our “Drop In Replacement” Heat Exchangers and Tube Bundles can fit identically to any of the heat exchangers made by Taco, Armstrong, Bell & Gossett, Thrush, ITT, Basco, Adamson, American Standard, Yula, Patterson-Kelly and many more, saving your company money and man hours.

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.
