Our Most Frequently Asked Questions
1. What information is required to prepare a quotation for an Enerquip heat exchanger?
To perform heat transfer calculations, we need the following:
- Thermal properties of the product and utility fluids (density, specific heat, thermal conductivity and viscosity) at a minimum of 2 different temperatures.
Also, we have a database of thermal properties for a wide range of common fluids; in many cases, the name of the fluid will be sufficient for us to find the fluid properties.
Example – my application is for cooling water for injection (WFI) using propylene glycol
- Specific process data – flow rates and inlet and outlet temperatures of product and utility fluids.
We also recommend that further details are provided, such as preferences for material of construction and connection size and type, required pressure and temperature ratings as well as maximum allowable pressure drop.
2. I need a heat exchanger for immediate delivery. Does Enerquip keep any units in stock?
Enerquip stocks a range of standard u-tube exchangers, common for CIP and water heating applications, as well as replacement tube bundles and gaskets for some of our most common exchangers.
3. Does Enerquip build custom heat exchangers? What is a typical lead time?
Enerquip’s team of engineers utilize in-house thermal design and mechanical design software to find custom solutions for our customers. Based on your specific process, we design a heat exchanger to fit your needs. Our project review team manages your order to insure competitive lead times. Depending on material availability and shop capacity, we can build custom equipment in as little as 6 weeks, and offer expedite options when possible.
4. What are the most common materials of construction in Enerquip heat exchangers?
We primarily work with austenitic stainless steels (304L & 316L). When requested, we can quote other alloys, including Hastelloy, AL6XN and Duplex.
5. Are Enerquip heat exchangers recommended for installation in a horizontal or vertical position?
While the heat exchangers can typically work in either position, some processes are better suited for a vertically mounted exchanger; condensers and evaporators, for example, perform more efficiently in a vertical position. Most liquid-to-liquid and steam heating processes will work fine in a horizontal position. Also, for sanitary processes that require enhanced drainability, we can offer designs for a pitched horizontal installation. Our proposal and specification sheet(s) will state the recommended position for your specific process.
6. What software do you use for the design of an Enerquip heat exchanger?
We use HTRI (Heat Transfer Research Inc) and their Xist & Xipe programs to perform the heat transfer calculations and complete the mechanical design using Solidworks 3D modeling software. We also use Compress to perform the calculations required to meet ASME Code.
