No. Is this supposed to be an alternative to sizing or rating? It does neither and seems redundant to be honest. 

If all you care about are inlet and outlet temperatures just let a supplier do the job as a paid quotation or for free if theyre being nice. 

If you've already used a design software on the other hand, then what's the point of this?

Sure, you can size it yourself or let a supplier do it. But then what? You’re still waiting days or weeks for a quote, with zero way to compare across vendors. I don’t have the patience for that – do you? I see that solved al in one.

You dont have patience to do your job?

Procurement takes some time, and its our job to ensure it is done well. There are other aspects to involving suppliers like getting valuable design input. You can always send out quotations to multiple vendors.

Does your tool do the entire design in one material or does it automatically assume the utility side is carbon steel to save cost? Does it handle stronger alloys like hastelloy?

I have the patience for my job but not the patience waiting for offers. It handles auto selection and calculates all possible variations in sizing. It is for bespoken shell and tube. For now only carbon steel and stainless steel. I like the generated 3D File.

How is it for bespoke hx design if all it does is look at temperature curves? If anything it feels like a tool for generic, off-the-shelf exchangers in which case I can see some usefulness.

It still feels like youre trying to solve a non-issue. If all you need is off-the-shelf exchangers, just look in a catalog.

The 3d file is cool and all but wouldnt you already have a model if you have a 3d model of your plant?

I think it's more than that. It generates individual solutions every time and calculates the thermal length to the millimeter. The speed is awesome. I often have the problem when I request an application I get different offers and they differ in type, heating surface and pressure loss and of course in price. The 3D helps because it is the heat exchanger that I end up with. So I can complete my planning and am also done with the technical clarification.

What do you mean differ in area and pressure drop.. that's your job as a process engineer to specify.

I'm a bit confused too. You're talking as if the tool can design a completely new heat exchanger but does it even take in fluid properties? It looks more like a glorified calculator rather than a real design tool to me.

When I create inquiries, I just describe my process in an email and then receive my offers from manufacturers who can interpret them themselves and these then differ.

It is a real design tool and not a calculator. There's a machine in there with a unique algorithm that lays out everything super quickly and you should just try it.

So you're not a process engineer then?

A real design tool would give you accurate areas, pressure drops and heat transfer as a function of fouling. There is no way that workflow would work in industry,

How does it use a unique algorithm when heat exchanger equations have remained fundamentally the same. Everybody says their algorithms are unique but they really aren't.

Not a good one like you. It has all your topics mentioned included. Fluid Property, Fouling, pressure drop etc. In every software else you have to be clear of the type of heat exchanger before. Here it is not about the type, there is a autoselection running all possible variations regarding to the application. Tube diameter, shell diameter, baffles, pitches and so on. I never have seen something like this before. And then including price, delivery time and so on.

I wouldnt call myself a good process engineer. I'm okay at best but know what's expected of me.

The website says fluid properties are coming but you make it sound like it already exists. How does it do its property calcs?

Have you used it in an actual procurement? How accurate was the cost and delivery times considering fabrication.
