What TIO does

TIO B.V. is a Dutch family-owned industrial manufacturer founded in 1934 and headquartered in Krimpen a/d IJssel, near Rotterdam. The company designs, engineers, and produces silencers, exhaust systems, blow-off silencers, spark arresters, pressure vessels, after-treatment systems (including integrated SCR), and complementary piping accessories for industrial noise control and emissions management. Core technology combines acoustic engineering (absorption, resonance, and combination silencer principles) with pressure equipment design compliant with PED 2014/68/EU, supported by in-house vessel calculation software, robot welding, and large-format glass bead blasting finishing. TIO operates a sister brand, TIO Yacht Exhaust Systems, for marine wet-exhaust applications, including TIER III-compliant superyacht and navy vessels.

The company sells exclusively through direct enterprise engagement with in-house sales engineers; no public pricing is offered and every solution is custom-quoted. Standard silencers are available from stock for same-day shipment, while custom projects are engineered against customer specifications for noise reduction, backpressure, materials, and certifications. Customers include Shell, Esso, DSM, ABB Lummus, Atlas Copco, HUG Engineering (datacenter emergency power), Zwart Techniek (marine/yacht power), an unnamed Dutch power company (35+ years), and project clients in the USA, Morocco, UK, Belgium, France, Canada, and the UAE. End markets are power generation and CHP, marine/yacht, industrial and compressor manufacturers, petrochemical/chemical plants, and data centers. Geographic reach spans Europe, North America, the Middle East, and Africa.

Operationally, TIO has run a single production facility in Krimpen a/d IJssel since 1957 and opened a second site, TIO II, in autumn 2025 to absorb growing order intake in the larger silencer segment after local Dutch permitting constraints (electricity grid, NOx limits) limited expansion of the original site. The company emphasizes long-tenured staff, multi-decade customer relationships, and direct engineering consultation as its primary commercial differentiators. Ownership remains private with no disclosed external investors or parent company.
