What Made with by Disait does

PTD Companies (Pressure Thermal Dynamics) is a privately held Dutch industrial group headquartered in Moerdijk, Netherlands, that designs, engineers, and manufactures custom mission-critical process and handling equipment from special and exotic alloys. The company operates through four core subsidiaries — Schelde Exotech (Vlissingen, NL), Verolme BV (Moerdijk, NL), Logan Industries (Hempstead, Houston, New Iberia, AL, US), and Nordic Custom (Jõelähtme, Estonia) — supplemented by EXOTECH HEERENVEEN, a sales unit established in 2025 targeting energy-transition markets. Across these entities PTD runs seven production facilities spanning the Netherlands, the United States, and Estonia, totaling 328,500 sq/ft of manufacturing space, approximately 250+ staff, and 2,500+ qualified welding procedures covering stainless steels, titanium, Alloy 800H, duplex and super duplex, nickel-based alloys (Alloy 600, 602CA, 617, 625), Hastelloy, Zirconium, Inconel, Monel, Tantalum, aluminium, and magnesium. The product portfolio spans pressure vessels, heat exchangers (all TEMA types), chemical/nuclear/fusion reactors, vacuum systems, hydraulic cylinders, winches/reelers/spoolers, BOP repair, piping and spooling, scrubbers, and special projects, supported by 2D/3D design, HTRI simulation, PV Elite pressure-vessel software, and high-pressure testing infrastructure including quayside access for 300+ ton loads.

The company sells project-by-project via direct enterprise engagement, with dedicated sales teams at each subsidiary and consultative co-design with customers. Revenue is generated through one-time equipment sales combined with recurring aftermarket services (installation, commissioning, on-site technicians, preventive maintenance, spares, and re-conditioning). The group is multi-certified across API (Q1, 6A, 8C, 16AR), ASME (U, R, VIII Div. 1 & 2), DNV, ABS, ISO 9001/14001/45001/3834, Lloyds, AD2000, PED, AQAP 2110, National Board R-Stamp, China D-level, EN 1090-1, DIN 2303 BK1-Class Q2 (defence welding), and EcoVadis Platinum (top 1% global). PTD was formally incorporated in 2018 under Bencis Capital Partners ownership following acquisitions of Verolme (2015), Logan Industries (2018), and Schelde Exotech (2019), with Nordic Custom added in 2020 and is led by CEO Juul Ijzermans, who joined as CEO and shareholder in 2016.

PTD serves blue-chip clients in process industries where high corrosion, extreme pressure, and high temperature are non-negotiable, including polysilicon/solar (FBR, hydrogenation reactors, polysilicon columns), nuclear and fusion (mission-critical pressure equipment), petrochemical (high-alloy heat exchangers, gasification burners), oil and gas exploration (BOP repair, hydraulic systems, offshore handling), defence (submarine hull support, DIN 2303-qualified welding), space (vacuum systems, aeronautical components), hydrogen (liquid ammonia-to-hydrogen reactors), and light-weight batteries (silicon anode process equipment). Pricing is not publicly disclosed and is quote-based per project, reflecting the custom-engineered nature of every order.
