What Enervent Zehnder does

Enervent Zehnder Oy is a Finnish manufacturer of mechanical ventilation units with energy recovery, founded in 1983 and headquartered in Porvoo, Finland, where it operates a single manufacturing plant producing the full product portfolio. The company has been a wholly-owned subsidiary of the Swiss-based Zehnder Group since 2018, and from 2026 its products will be marketed internationally under the Zehnder brand while retaining the Enervent Zehnder Oy legal name. It employs roughly 80–82 staff, with broader firmographic listings placing headcount in the 101–250 range.

The core technology is a proprietary rotating heat exchanger (pyörivä lämmönsiirrin) that transfers both heat and humidity between exhaust and supply air streams, achieving annual heat recovery efficiency above 90% and supporting the highest EU ecoDesign energy classifications (A to A+). The portfolio spans residential units (Pinion, Salla Compact, Pingvin XL, Svea, Svea Cooler, Pelican Z, Alta, and the horizontal LTR-3, LTR-5 Z, LTR-5 Z Cooler for renovation), commercial and industrial units (Pegasos Z, Pallas, LTR-7 Z), and a complementary ecosystem of Zehnder air-distribution ducts (with RapidLock connections), Enervent CHG geothermal pre-heating/cooling coils, eAir and eWind control systems, the iSLa mobile application, and Zehnder Care service agreements.

The business model is predominantly indirect, relying on a network of authorized resellers and service partners across Finland, plus wholly-owned distribution in Norway through Noram Produkter AS (selling under the Exvent brand) and independent distributors in Sweden, the Baltics, Poland, Ukraine, Germany, and France. Revenue streams comprise hardware sales of ventilation units, project-based direct sales for large commercial and industrial deployments, e-commerce sales of filters and spare parts through webshop.enervent.com, and recurring managed-services revenue via Zehnder Care maintenance agreements. Pricing is quote-based through the channel for full systems, with unit pricing published only for consumables online.
