Kooiman Apparatenbouw

What Kooiman Apparatenbouw does

Kooiman Apparatenbouw b.v. is a Dutch industrial fabricator founded in 1912 and headquartered at Baanhoek 196, 3361 GN Sliedrecht, the Netherlands, with a workforce of approximately 50 employees. The company designs, engineers and manufactures custom process equipment — shell and tube heat exchangers (Fixed, U-tube, Floating Head, and Kettle TEMA types up to 30 tons), pressure vessels (reactors, incinerators, mixing/storage/buffer/filter vessels up to 4 m diameter, 50 mm wall thickness, 30 tons), and flow cells (specialized pipe spools for ultrasonic flow metering up to 3 m diameter). Manufacturing is supported by separate hangars for stainless/non-ferrous and carbon steel production, an in-house x-ray bunker, hydrostatic testing to 600 barg, and specialized welding techniques (orbital tube-to-tubesheet, weld overlay, submerged arc) across complex materials including duplex/super duplex, Inconel, Hastelloy, Monel, titanium and 254 SMO.

The customer base is concentrated in global oil & gas, petrochemical, chemical and industrial gas majors — including Shell, DuPont, Air Liquide, Fluor, Huntsman, LyondellBasell, Indorama, Chemours, Shin-Etsu and Bluewater — with the company claiming worldwide reach. Revenue is generated primarily through one-time, project-based sales of bespoke engineered equipment priced via quotation against customer specifications and international design codes (ASME VIII, EN 13445, PED, AD Merkblatter, API, ASME B31.3, EN 13480, PD 5500, TEMA), supplemented by replacement parts, retubing/refurbishment services and engineering consultation on code and material selection. Kooiman has been a member of the Rootselaar Group since 2017, sharing engineering resources with sister firm Hadetec and benefiting from cross-Group expertise across cryogenic and tank specialists.

Recent moves6 records

Expansion highlights4 records

Emerging players

• Chart Industries: Specialist in cryogenic and process equipment including heat exchangers and pressure vessels for industrial gas, LNG and petrochemical applications - closely overlaps with Kooiman's flow-cell and pressure-vessel work serving Air Liquide-type industrial gas customers.

Direct peers

• API Heat Transfer: Dedicated heat exchanger manufacturer (shell-and-tube, plate, air-cooled) serving petrochemical, chemical and oil & gas customers worldwide - a direct peer of similar product emphasis to Kooiman's TEMA heat exchanger offering.
• Holtec International: Engineering and fabrication company producing custom pressure vessels, heat exchangers and heavy process equipment for nuclear, petrochemical and industrial customers - directly comparable in custom heavy-fabrication services and exotic-material capability.
• Kelvion Heat Exchangers: Specialist heat exchanger manufacturer (formerly GEA Heat Exchangers) supplying shell-and-tube, plate and air-cooled units to oil & gas, petrochemical and chemical customers - directly comparable to Kooiman's TEMA-range heat exchanger product line and target verticals.

Others

• Cryovat: Sister company within the Rootselaar Group focused on cryogenic vessel manufacturing; shares engineering and certification resources with Kooiman and serves overlapping industrial gas and petrochemical customers - sibling company, not a direct competitor.
• Hadetec: Engineering firm within the Rootselaar Group whose library was combined with Kooiman's; provides complementary design and engineering services on the same heavy process equipment projects - adjacent rather than competing.

Broad incumbents

• Babcock & Wilcox: Long-established supplier of industrial steam and heat-transfer equipment (boilers, heat exchangers, environmental systems) for power, oil & gas and process industries - a broad incumbent with overlapping heat-exchanger and pressure equipment capability.
• SPX Heat Transfer / SPX Technologies: Supplies heat exchangers and process equipment for power, petrochemical and industrial markets through legacy SPX Heat Transfer brands, comparable to Kooiman's custom engineered process-equipment scope but at much greater scale and geographic reach.
• GEA Group: Large German engineering group with a significant process-equipment division (separators, homogenizers, and heat exchangers) serving food, chemical and process industries - a broad incumbent whose heat exchanger and process-equipment lines overlap Kooiman's portfolio.
• Alfa Laval: Global leader in heat transfer, separation and fluid handling with a major presence in plate, brazed and shell-and-tube heat exchangers for O&G, petrochemical and industrial gas customers - a large incumbent whose core heat-transfer portfolio overlaps Kooiman's primary offering.
