Marine boilers are critical auxiliary equipment aboard most ocean-going vessels — generating steam for fuel oil heating, cargo heating on tankers, domestic hot water, and deck machinery operation. The three most common marine boiler brands in commercial service are Aalborg Industries (now Alfa Laval Marine), Miura, Sunrod, and Kangrim. As a marine boiler spare parts supplier in India, Marinexa provides genuine and reconditioned boiler components for all major brands — sourced from Bhavnagar, Gujarat, with emergency 24–48 hour global delivery.
Marine Boiler Brands We Supply
Aalborg Industries (Now Alfa Laval Marine Boilers)
Aalborg boilers are the most widely installed marine exhaust gas boilers and composite boilers in the global fleet. The Aalborg brand was acquired by Alfa Laval in 2012 but vessels continue to carry Aalborg-branded units:

- Aalborg AV-6N, AV-8N — vertical oil-fired auxiliary boilers
- Aalborg OC / OL series — exhaust gas economisers; fitted on main engine exhaust systems
- Aalborg OM series — mini boilers for smaller auxiliary steam requirements

- Kangrim KAB, KOB series — Korean-built oil-fired auxiliary boilers; widely fitted on Korean-built bulk carriers and tankers
- Kangrim composite boilers — oil-fired + exhaust gas combination units
Sunrod Marine Boilers
- Sunrod boilers — Swedish-origin brand; commonly found on Scandinavian-built vessels

The Alang Advantage for Marine Boiler Parts
Most vessels broken at Alang carry complete Aalborg and Kangrim boiler systems. Burners, feed pumps, safety valves, level controllers, and control panels are removed and available through Marinexa’s Alang-sourced supply at 40–60% below new OEM cost. For older Aalborg AQ and AV series where OEM parts availability from Alfa Laval can be limited, Alang-sourced components often represent the only practical supply option.
