SACOME Heat Exchangers FAQ
Which data are required to prepare a quotation for heat exchangers?
- Thermal properties of the product (density, specific heat, thermal conductivity and viscosity at least at 2 temperatures).
- Thermal balance (inlet temperature, outlet temperature, flowrate both of product and service.
To prepare the quotation it is also recommendable to provide some further details, as: required construction material, available space in the plant, connections of product and service side, or maximum pressure drop.
Which are the most common construction materials in a SACOME heat exchanger?
Are the SACOME heat exchangers suitable for handling corrosive fluids?
You can find further details with regard to intergranular corrosion in austenitic stainless steel by clicking on the following link:
My product is new, and I don’t know its thermal properties. How can we proceed?
And, if needed, we have a close collaboration with specialized laboratories and universities to do tests and determine the real values of the thermal properties for a given sample of product.
Which software do you use for the thermal design of your heat exchangers?
Our R+D+i Department is continuously working on the refining of our thermal calculations methods and, as we are a registered member of HTRI, our technical staff are provided ongoing training and get online support by their experts.
What are the standard performance over-design margins in the SACOME heat exchangers? Do you take account of fouling effects?
Our aim is to offer a reliable and flexible solution to our customer.
I need a heat exchanger for an immediate delivery. Do you have any unit in stock?
You can find further details on our V SERIES Heat Exchangers by clicking on the following link:
Do you build custom-designed heat exchangers? Which is the delivery time?
When it comes to custom-made units, we study case by case and will inform you about our best manufacturing delivery time.
Our Projects Department issues the drawings of the units and when we get the client’s approval we get on with the manufacturing.
If I have connected my heat exchanger in a different way than that suggested by SACOME, will it work properly?
Please check up the nozzle disposition in the drawing and documentation we supply with our equipments.
Are your heat exchangers recommended to work in horizontal or vertical position?
Moreover, a pitched horizontal installation is also a possibility we recommend for applications in which self-drainability is required. In our technical offer we state the recommended position.
How can your corrugated tube heat exchangers be cleaned on site?
What flowrate should I run for CIP?
What is the lifetime of your heat exchangers?
What is the lifetime of your heat exchangers?

How can your heat exchangers be insulated?
My product contains big-size solids. Which configuration do you recommend me?
Please consult our online catalogues for SACOME monotube heat exchangers:
Has SACOME its own manufacturing facilities?
We have been carrying out the engineering and manufacturing of our equipment since 1978:
What % of heat recovery can be reached with the SACOME corrugated heat exchangers?

Can the SACOME heat exchangers do direct (product/product) regeneration?
However, this is something that can be done for certain applications, whilst for others, due to more demanding hygienic requirements, we recommend to do this as indirect regeneration. In the indirect regeneration the heat recovery is done in 2 different heat exchangers by means of an in-between close water loop.
Are your heat exchangers outfitted with baffles in the shellside?
The baffles play different roles, as they support the inner tubes, restricting thus the unsupported span, and they also help to improve the crossflow stream in the shellside, enhancing the heat transfer, what can be especially important for applications handling low conductivity fluids, as mineral or vegetable oils.
The baffle distribution and chosen geometry is also key when it comes to certain applications with high risk of vibrations, i.e. gases and phase changes in the shellside.
It’s worth to mention that the baffle analysis is one of the strengths of our software Xist, edited by HTRI (Heat Transfer Research Inc.), and it even incorporates a specific module for the checking of vibrations.
What is the maximum design pressure and temperature for a SACOME heat exchanger?
Our Technical Department checks the mechanical design according to AD Merkblätter, ASME Section VIII Div. 1, EN 13445, among other design codes. In adidition, Finite Element Analysis for special applications. Special attention must be paid to the choice of the material for high temperature applications, as it occurs for the heat recovery processes for exhaust gases and incineration gases.
