Frequently Asked Questions
Yes. An example of this layout can be viewed in the current Hot Pak Product page. This layout is also available in a duplex option with two Hot-Paks on one frame. Drawings and dimensions are available upon request.
Yes. Thrush does stock some heat exchangers. All of the standard model Straitube heat exchangers are in stock. Models of popular u-tubes are also stocked in standard design construction.
Yes. Thrush can build to virtually any customer's needs and dimensions. We can design and build complete drop-in replacements for most u-tube and fixed tube applications. As standard, we build to ASME section VIII, Division 1 standards, and can also accommodate TEMA standards as well. Keep in mind that some dimensions or requirements may conflict with ASME codes and some compromises may be required.
Yes. Thrush can manufacture replacement tube bundles for virtually any type or brand of u-tube heat exchanger. In some cases field measurements are required to insure proper fitment.(Download the replacement tube bundle dimension and data sheet.) Thrush offers various material and tube options to meet the most demanding operating requirements. Contact your local Thrush representative today to learn more.
It depends on whether it is a u-tube or a stock Straitube. The u-tube gaskets are based on the nominal diameter of the heat exchanger and not the diameter of the gasket. For example, a 12" u-tube uses a 12" heat exchanger gasket. This gasket is the same diameter as the raised face of an ANSI flange. A Straitube gasket is model specific and should be chosen based on the actual model of the heat exchanger. For example, a model 320 Straitube uses model 260, 320, and 380 replacement gaskets. Straitubes also have front and rear-specific gaskets. Be sure to specify if it is for the front or the return head.

Double wall heat exchangers are design to keep the working fluids from cross contaminating if a tube wears or fails. Each tube is actually a tube within a tube and there are two tubesheets. The tubes are sealed to the tubesheet that it is in contact with and a gap between the tubesheets lets a leaking tube drip between the tubesheets to signal a tube failure. Many plumbing codes require this for heat exchangers being used to heat domestic water. Check your local codes to see if it affects your application.
It depends on the type of circulator and bearing used in the circulator bracket assembly. All sleeve bearing circulators require oil lubrication. Sleeve bearing bracket assemblies have a flip up oil fill cap on them. Check the operating instructions for your specific pump model to be sure. Don't forget to check the motor as well. Sleeve bearing motors have similar oil cups located on top of them as well. (Place instructions or link to the location on the website of operation and maintenance manuals here).
Only if it is a vertical circulator or pump. All Thrush circulators or pumps that may be installed with the shaft in a vertical position have a "V" for "Vertical" in their model designation. Example models: V, 22V, GTV, TV2g, etc.
