Cooling Towers Spares

What is a “Bottle-Shaped FRP Cooling Tower”? It is a compact, induced-draft, factory-fabricated cooling tower made of Fiber Reinforced Plastic, featuring a cylindrical or slightly tapered “bottle-like” outer casing, usually housing all components in a single, integrated unit.It is NOT a giant hyperbolic...

Bottle-Shaped Cooling Tower (Hyperbolic Natural Draft) Definition & Visual Identity A bottle-shaped cooling tower refers to the iconic, large hyperbolic natural draft cooling tower commonly seen at thermal power plants and large industrial facilities. Its shape resembles a giant bottle or hourglass. Why the Hyperbolic Shape?...

A Forced Draft, Counter Flow Cooling Tower is a mechanical draft cooling tower where air is pushed (forced) into the tower by a fan located at the air inlet, and the flow of air is in the opposite direction to the flow of falling water. . How It Works (Step-by-Step) 2. Key Components 3. Advantages Comparison with Induced Draft Counter Flow...

Material Selection PVC (Polyvinyl Chloride) CPVC (Chlorinated PVC) Polypropylene (PP) Wood Fouling and Maintenance Concerns Common Problems: Prevention: Selection Criteria When choosing fill type, consider:

Cooling Tower Fills/Packing: The Heart of Heat Transfer Cooling tower fills (also called packing or wetdeck) are the core heat exchange medium inside a cooling tower. They create an extensive surface area for air and water to interact, maximizing evaporation and cooling efficiency. Primary Function To increase contact surface...

Applications 1. Water-Scarce Regions 2. Urban/High-Visibility Sites 3. Cold Climate Facilities Facilities with Variable Loads 5. Environmental Sensitive Areas Economic Considerations When to Choose This Design: Condition Recommendation Water cost > $3/1000 gal Strong candidate Strict plume regulations Often required Freezing concerns + high...

Combined Flow Coil/Fill Evaporative Cooling Tower A Combined Flow Coil/Fill Evaporative Cooling Tower (also called a Hybrid Wet/Dry Tower or Two-Stage Tower) is an innovative design that integrates both a closed-circuit coil bundle AND open tower fill media into a single unit, typically in series. This combination...

Common Applications

A Direct-Contact or Open Evaporative Cooling Tower is a heat rejection device where the process water to be cooled is in direct physical contact with the atmospheric air, and cooling is achieved primarily through evaporation. The name breaks down into two key parts: 1. “Direct-Contact” or “Open” This...

To calculate the Blow-down Loss, we need one more critical piece of information: the Evaporation Loss (E). The Blow down is directly derived from the evaporation rate and the Cycles of Concentration. The fundamental formula relating Blow down (B), evaporation (E), and COC is: B=ECOC−1B=COC−1E​ Where: Step-by-Step Calculation with...

1. EVAPORATION LOSS This is the desired and essential process that makes cooling towers work.

Factors Affecting Cooling Tower Performance Cooling tower performance is influenced by a complex interplay of design parameters, operating conditions, and maintenance factors. They can be categorized as follows: I. THERMODYNAMIC & ENVIRONMENTAL FACTORS 1. Ambient Wet-Bulb Temperature (WBT) 2. Ambient Dry-Bulb Temperature &...

The Cooling Tower Nozzle is a small but mission-critical component in the water distribution system. It is responsible for the precise and uniform dispersion of hot water over the fill media, which is fundamental to achieving optimal thermal performance. Core Function To distribute hot return water as evenly as possible...

Film vs. Splash Parameter Film Fill Splash Fill Efficiency Very High. More surface area per unit volume allows for a more compact tower design. Moderate to Good. Requires a larger tower volume for the same cooling duty. Pressure Drop Higher (due to more restrictive, closely spaced channels). Lower (more open structure). Fouling Tendency...

The motor is a critical component of a mechanical draft cooling tower (both field-erected and factory-assembled), acting as the heart of the air movement system. Here’s a comprehensive breakdown of cooling tower motors, with a focus on their application in large  Core Function The motor’s sole purpose is to drive the fan(s) that create...
