What SEM does
SEM srl is an Italian private limited company founded in 1985 and headquartered in Termoli (CB), Italy, that designs and manufactures high-efficiency Air Handling Units (AHUs) for Heating, Ventilating and Air Conditioning (HVAC) applications. The company produces three core product lines under the MYH family — MYHA (pentapost aluminium-and-nylon-corner construction, 70 sizes, 1,000–180,000 m3/h), MYHB (pentapost with thermal-break inserts, certified T2/TB2 EN1886, aimed at hygienic applications), and MYHC (frameless panel-to-panel connection, 30 sizes, 1,000–60,000 m3/h, for high-hygiene requirements) — all of which carry Eurovent (EN1882/EN13053), VDI 6022, DIN 1946, ISO 9001:2015, IQNET, CE, and ErP 2018 certifications. SEM holds three registered patents covering its pentapost casing, its frameless panel-to-panel connection, and its thermal-break insert, and runs CAD-CAM / 3D / EFM tooling on a 4,000 sqm production site backed by a 120 kWp rooftop photovoltaic installation.
The company's commercial model combines direct enterprise field sales through its own worldwide commercial network with a layer of authorized distributors across at least nine European countries (Belgium, Serbia, Poland, Portugal, Ukraine, Spain, Romania, Kosovo, and Hungary), and includes an OEM relationship with a primary worldwide HVAC company. Pricing is quote-based and project-specific, with units configured in monoblock or modular layouts and available in multiple physical configurations (single or double fans, in line, L or U shaped, double decker or side by side, vertical). Revenue is generated primarily through hardware sales of customized AHU units supplemented by professional design support and after-sales service, with end-customer segments split across commercial buildings (offices, hotels, retail), healthcare and hygienic environments (hospitals, clean rooms, pharmaceutical and food facilities), and industrial/process applications. SEM employs approximately 60 workers and staff at its Termoli facility and operates as an independent, privately held Italian srl with no disclosed parent company, institutional investors, or public listing.
