Developed by MAPSEC, EQUILOG is a new generation hydraulic balancing suitcase, integrating a method based on the actual thermal behaviour of installations. Rooted in field practice proven since the 2000s, this approach is now structured within a high-performance digital tool, designed for heating and balancing professionals. EQUILOG allows for complete balancing of an installation by overcoming the uncertainties related to theoretical data, by directly relying on the analysis of return temperatures. It is compatible with all balancing components (balancing unions, balancing valves with or without pressure tappings, etc.) and guides the user step-by-step in the field, up to the generation of a report compliant with the requirements of the CEE (Certificats d'Économies d'Énergie) schemes.
