Chandigarh, 29th May, 2025 – Sintex by Welspun, India’s leading and trusted manufacturer of quality water storage solutions, is expanding the reach of Sintex Trupuf — the India’s first ‘truly’ insulated water tank — as temperatures soar due to heat wave across India this summer. Designed to endure extreme weather conditions, the 50 mm polyurethane foam serves as an effective insulator, maintaining the stored water’s temperature close to its original state. The tank is made from 100% virgin food-grade plastic ensuring better health thereby eliminating health risks caused by recycled plastic. It also has anti-bacterial, anti-fungal, anti-algae, and anti-viral properties — making it a safer and healthier choice for families. Designed to perform in both intense heat and freezing cold, Trupuf is fast becoming a preferred choice amid evolving customer needs and preferences. While the product is especially relevant in peak summer, Trupuf’s insulation also makes it suitable for extreme winters — offering an effective alternative to heavy steel tanks.
Prolonged sun exposure significantly heats stored water and creates an ideal environment for algae formation and bacterial growth. The resulting unpleasant odor impacts daily water usage and hygiene. Trupuf is designed to function like a thermos — maintaining the water’s original temperature regardless of the climatic conditions. With a thicker make and UV-stabilised outer shell, Trupuf deflects sunlight and prevents algae formation. The tank is equipped with unique self-Locking lid with ‘Hexa Bolts’ that secure the top from external interference. The central insulation layer reduces heat transfer, allowing the tank to maintain the water at its original filling temperature. Internal testing shows that the water temperature fluctuates by no more than 0.5°C from its original filling temperature, even in extreme climatic conditions.
Trupuf comes with a 15-year warranty, reflecting the quality and durability that Sintex has consistently delivered to its customers. A preferred choice for institutions, educational facilities, corporates, bungalows, and individual homes across regions, Trupuf meets the everyday demands of a wide base. Backed by Sintex’s trusted quality, wide distribution and oplumber network, and legacy of product innovation, the product continues to gain relevance in regions where climate conditions are reshaping everyday essentials.
Yashovardhan Agarwal, Managing Director, Welspun BAPL Ltd and Director at Sintex – “The Sintex Trupuf was created to solve a very real, everyday problem — water that becomes too hot and uncomfortable to use during peak summer. With heatwaves across the country, our focus is on making water storage safer, more comfortable, and more dependable for families and businesses alike. Trupuf brings together durability, hygiene, and thermal insulation in a way that genuinely improves how people experience stored water in extreme weather conditions. For us, smarter water storage is the first step toward healthier homes and communities.”

Each region presents unique summer challenges — from rooftop exposure in Delhi and UP to extreme heat in Rajasthan, Trupuf effectively addresses these conditions through its thicker make and enhanced insulation design.
