Paharpur Cooling Towers

What Paharpur Cooling Towers does

Paharpur Cooling Towers Ltd. is a privately held, family-controlled (Swarup family) Indian industrial manufacturer founded in 1948 and headquartered in Kolkata, West Bengal. The company designs, engineers, manufactures, and services the complete range of process cooling equipment, spanning wet cooling towers (factory-assembled unitary range, comfort/intermediate series 9/10, 15/18, S-100/120, and large industrial Class 400-1000 plus Natural Draught hyperbolic towers), dry cooling systems (Air-Cooled Steam Condensers with DRH architecture and Air-Cooled Heat Exchangers), and the Infinium Adiabatic Cooler hybrid. Proprietary design elements include Lowproach technology (approach temperatures as low as 1°C), XCEL drift eliminators (water loss to 0.005% of flow), and Uni-flow AQ horizontal-discharge architecture.

Paharpur operates six fully integrated manufacturing plants — three in India (Bhasa, Kolkata-Oil Installation Road, Sahibabad), one in Savli, one in Kandla, and one in Zhangjiakou, China (via subsidiary SPG Dry Cooling Technologies) — producing both factory-assembled and field-erected products. The company reports more than 82,000 cooling towers and heat exchangers sold across 60+ countries since 1948, more than 70% of India's power plants served, and a global installed base delivering over 11,000 billion litres of water per day. Customer-facing offices span 6 Indian metros and 11 international locations across Belgium, China, South Korea, USA, UAE, Spain, Switzerland, Turkey, Italy, Mexico, and Nigeria.

The business model rests on three revenue streams: (1) capital-equipment sales of cooling towers and dry cooling systems to industrial and commercial customers via direct enterprise field sales and customized quotation; (2) original spare parts, where Paharpur emphasizes only its own spares deliver the engineered thermal performance; and (3) service, repair, condition, and reconstruction/upgradation contracts tied to the installed base. Pricing is not publicly disclosed; transactions are negotiated project-by-project. Customers span power generation (primary), HVACR/commercial buildings, chemical & fertilizer, metals, sugar, pharmaceuticals, food & beverage, paper, and oil & gas / cement. Certification credentials include CTI (Cooling Technology Institute) thermal-performance certification and CII Greenpro ecolabelling. Notable reference projects include CTI-certified CF3 towers for L&T at the Statue of Unity, Greenpro-Certified Lowproach towers for IHCL under IFC's TechEmerge program, and seismic-surviving Class-400 towers in Chile.
