In 1976, Mihir Engineers gave India its first Round Bottle Shaped Counterflow FRP Cooling Tower — the RB Series — making us the pioneer of this design in the country. It was also part of our broader first: Mihir was the first company in India to develop and manufacture FRP cooling towers in place of conventional wooden towers, a shift the rest of the industry soon followed.
The RB Series is a counterflow tower specially designed in a round shape for installations facing high wind velocity, with a corrosion-resistant, fire-retardant FRP casing and basin. It's engineered for cooling capacities from 10 TR to 450 TR per cell.
Benefit of Service
Round shape specially designed for high wind velocity installations
Casing and basin in corrosion-resistant, fire-retardant FRP
Hot-dip galvanized supporting structure for long-term durability
Corrosion-Resistant Structure
Structural supports in Pultruded FRP with MSHDG hardware (stainless steel optional) — built for highly corrosive applications.
Faster Execution
Minimum site activities and low operating weight mean quicker installation with less on-site work.
Energy Efficient
Aerofoil-shaped, hollow FRP fan blades on an induced-draft counterflow design for optimum airflow efficiency.
High Cooling Capacity
Engineered to cool up to 4,000 m³/hr/cell, with a continuously formed casing for a smooth finish on both sides.
More information
Corrosion & Fire-Retardant FRP Casing
Casing and basin are built in corrosion-resistant, fire-retardant FRP for long-term reliability in demanding conditions.
Hot-Dip Galvanized Supporting Structure
The supporting structure is hot-dip galvanized, protecting against corrosion and extending the tower's operational life.
Designed for High Wind Velocity
The round shape is specially engineered for installations exposed to high wind velocity, offering added structural stability.
Cooling Capacity Range
Available from 10 TR to 450 TR per cell, making the RB Series suitable for a wide range of application sizes.
