What Unit Birwelco Group does
Unit Birwelco Group is a privately held UK-headquartered engineering group formed by bringing together Birwelco (Halesowen, West Midlands), UnitBirwelco IISP Thermal Equipment Private Limited (Noida, India), and UnitBirwelco Middle East under unified control. Tracing its operating heritage to Birwelco's 1920 founding (with Unit Superheater Engineering established in Swansea in the 1970s), the group markets itself with over 100 years of combined experience in thermal equipment design, fabrication, and installation. It operates an in-house engineering, design, fabrication, and installation model with facilities and offices in the UK, India, the Netherlands, and the Kingdom of Saudi Arabia, and reports achieving carbon negative status in 2020.
The group's product portfolio centres on heat-intensive industrial equipment: fired heaters, flares and Flare Gas Recovery systems, shell-and-tube and air-cooled heat exchangers, superheaters, process skids, ASME-certified pressure vessels, and storage tanks, complemented by on-site heat exchanger repair services using techniques such as the Curtiss-Wright Pop-A-Plug tube-leak system. Marquee project references include an 85MW HVAC back-up heater for the Yamal LNG plant in Sabetta, Northern Russia, a Vacuum Column Heater Package executed with Toyo Engineering India for Indian Oil Corporation, a green diesel and jet fuel plant in Sweden, and Esso Fawley refinery work, demonstrating delivery capability at the multi-megawatt and multi-unit project scale.
Revenue is generated through a mix of bespoke one-off capital equipment contracts, professional engineering and consultancy services, on-site repair and maintenance work, and aftermarket spares and upgrades. Pricing is quote-based and not publicly disclosed, consistent with the project-driven, enterprise-only sales motion across end markets including oil and gas (primary), power generation, petrochemicals and chemicals, hydrogen, pharmaceuticals and food, marine, and energy-from-waste. The group is privately held with no public listing, no disclosed external investors, and no funding rounds in the source material; ownership is described as founder or management-owned, with specific shareholdings undisclosed.
