Colasit

What Colasit does

Colasit AG is a privately held Swiss specialty industrial manufacturer, founded in 1945 and headquartered in Spiez, Switzerland. The company designs, develops, and manufactures chemically resistant plastic systems and components for handling aggressive gases, exhaust air, and corrosive liquids. Its product portfolio spans seven core categories: plastic ventilators, exhaust air purification systems, ventilation ducting, process and shut-off flaps, process plants and tank storage, custom apparatus and housings, and fibre composite molded parts (GFK/CFK/AFK), with a secondary offering in aquaculture systems. Manufacturing is centralized in Switzerland and the Netherlands, and the company supports its hardware with two engineering software tools, ColaVent (ventilator sizing) and SIMCHEM (chemical process simulation).

The company sells exclusively into B2B industrial channels through direct enterprise sales and a network of 15 partner representations providing local installation, service, and maintenance. It operates five wholly-owned branches across Europe (Switzerland, Netherlands, Germany, Sweden) and Asia (Singapore, India), giving it a multi-continental footprint. Customer segments are horizontal within industrial processing: chemical plants, manufacturing facilities, environmental technology, and aquaculture operators all require corrosion-resistant equipment that conventional metals cannot economically provide. Pricing is quote-based, project-driven, and structured around multi-year contracts for custom-engineered systems, and certifications include ISO 9001, ISO 14001, and ATEX compliance for explosive atmospheres. The company is privately held with no disclosed parent company, no external funding, and no publicly traded equity, operating as an apparently independent industrial business since its founding over 80 years ago.

Revenue mechanics are entirely hardware-driven: custom-engineered plastic systems are designed to customer specifications, manufactured in Switzerland or the Netherlands, and delivered with associated installation and after-sales services through the partner network. Colasit positions itself as a sustainability-aligned manufacturer using recyclable plastics and adhering to UN Sustainable Development Goals, differentiating on long equipment lifespan, corrosion resistance, and the ability to specify custom geometry for chemically aggressive service environments.

Core offering

Colasit designs, develops, and manufactures custom-built chemical-resistant plastic equipment and systems for handling aggressive gases, exhaust air, and corrosive liquids. The portfolio spans plastic ventilators, exhaust air purification systems, ventilation systems (square and round), process and ventilation flaps, process plants with tank storage, custom apparatus and housings, fibre composite molded parts, and aquaculture systems, complemented by proprietary ColaVent sizing software and SIMCHEM process simulation tools.

Product overview

Colasit is a single-product-line manufacturer offering a comprehensive portfolio of chemically resistant plastic systems and components for aggressive gases, exhaust air, and corrosive liquids. The product range centers on industrial-grade plastic construction across seven core product categories: Kunststoffventilatoren (plastic ventilators), Abluftreinigungsanlagen (exhaust purification systems), Lüftungen (ventilation systems in square and round configurations), Prozess- und Lüftungsklappen (process and ventilation flaps), Prozessanlagen (process plants and tank storage), Apparatebau (apparatus and housings), and Faserverbundformteile (fibre composite materials including GFK/CFK/AFK). The company also offers specialized software tools including ColaVent for ventilator sizing and SIMCHEM for chemical process simulation. Development and manufacturing occur in Switzerland and the Netherlands. All products are designed for chemically aggressive environments and are made from recyclable plastics, with the company adhering to UN Sustainable Development Goals.
