EchTherm™

NeoTherm Consulting est le développeur du logiciel de calcul EchTherm™ dédié aux échangeurs thermiques.

This software is distributed exclusively by GRETh, Groupement pour la Recherche sur les Échangeurs Thermique (French Heat Exchanger Research Group), a reference in the field.

EchTherm (for Heat Exchange) is intended to be easy to use and easy to learn, it integrates a new approach and a new sizing approach via basic engineering tools, this one is more progressive (step by step) and is based on the following theme: "From technology to sizing of exchangers"

This product is to be considered as a real "toolbox" for heat exchanger sizing. Thanks to its user-friendly interface, it is easy to use, didactic and meets the needs of many engineers, both experts and beginners.

Indeed, its "step by step" approach allows an easy and quick understanding of the phenomena involved in heat exchangers, as well as of the different parameters interacting in the sizing of exchangers, starting with the technological choice up to the fine analysis of the choice of empirical correlations and the operation in degraded conditions.

In addition to the calculation of the various parameters essential to the sizing of heat exchangers such as heat exchange coefficients and pressure drops, this software integrates many tools and thus allows :

To help in the choice of an exchanger technology adapted to an industrial process and its constraints: Technology Decision support;
To size or simulate the performance of a heat exchanger using simplified methods: Sizing / Simulation sheets;
To bring an expertise on the methods/correlations for the calculation of the thermo-hydraulic parameters (transfer coefficient and pressure drop): Expertise sheets (Expertise);
To assist in the thermal or mechanical diagnosis of the operation of a heat exchanger in degraded conditions: Mechanical & Thermal Diagnostic sheets;
To have access to additional calculation tools: Tools (TOOLS+) sheets.

RefriHVAC™

NeoTherm Consulting develops a calculation software dedicated to the refrigeration and HVAC industry : RefriHVAC

In this field, refrigeration specialists or business managers often use Excel tools developed internally. These tools are extremely time consuming to create, difficult to use and to maintain (obsolescence of the macro language, loss of knowledge due to the departure of the developer).

Custom-made software

NeoTherm develops your software with a sustainable solution regarding operation, compatibility and maintenance.

We develop custom software for our customer’s thermal applications (heat exchanger, thermodynamic cycle, thermal system). We develop for you specific calculation methods and we can also implement your proprietary business rules. Our development tools allow the creation of advanced, interactive and ergonomic interfacing.

In the field of thermal and energy in the broadest sense, many engineers and project managers often use Excel tools developed internally. These tools are extremely time-consuming to create, difficult to use and to maintain (obsolescence of the macro language, loss of knowledge due to the departure of the developer).

NeoTherm Consulting proposes the development of your calculation tools designed especially for you according to your needs.

Your needs can be clearly defined or NeoTherm can also intervene in the expression phase of the need.
Our software is equipped with ergonomic, advanced and easy to use interfaces for any collaborator.
The results can be displayed as self-generated tables and/or curves, custom specification sheets including your logos, your own diagrams or diagrams designed by us at your request.
The operation is made easy because of the presence of numerous aids (diagrams, explicit buttons) directly on each software tool.
Maintenance is reduced to a minimum and compatibility is assured.
The source code can be blocked, made available (reading) or modifiable according to your wishes.

Example of realization

Software development of heat exchanger design for an OEM based on the customer's proprietary business rules;
Software development of exchanger design for new technology;
Software development for the simulation of the performances of a cold production system (simulation on each component of the cycle, research of the laws of operation, reading of weather file, automatic creation of tables and curves, ...).
