ModuSat® Selector

The ModuSat® Heat Interface Unit Online Selector is an intuitive tool that recommends the ideal HIU(s) for any district or communal heat network development, based on project parameters entered by the user.

Evinox created the Selector with M&E consultants in mind, aiming to provide an online tool, which is easy to use and that can help with sizing and selection whilst saving time for the specifier.

In additional to the sizing and selection functionality, the Selector also provides heating and hot water technical performance information specific to the users’ project, complete with Low Temperature Hot Water (LTHW) calculations for the whole heat network, which can act as a useful guide for the design and specification process.

Users can also save unit selections and calculations for each project and come back at any time to access or edit them or to create a new selection, making this a really useful resource for consultants.

“This unique new tool is an extension of the Evinox Heat Network Design Guide that is used by many M&E consultants in the UK. It draws on Evinox’s experience sizing HIU’s for numerous communal heating projects, and also recommendations from the Swedish District Heating Association Technical Provisions F:101, Danish Standard 439 and the CIBSE CP1 – Heat Networks: Code of Practice for the UK, making it a really useful aid for the design and specification process” (Helen Gibbons, Evinox Technical and Design Manager)
