Project Overview

Customer: EPC Contractor
Location: Pakistan
Equipment: Counterflow Cooling Tower
Cooling Medium: Clean Water
Quntity: 2 Units

A leading contractor in northern Pakistan required a reliable cooling solution for a building materials manufacturing plant. The cooling towers were designed to support the plant’s recirculating water system under challenging environmental conditions characterized by heavy seasonal dust storms and significant day-to-night temperature fluctuations.

Challenge

The project site experiences frequent dust storms during spring and temperature variations of up to 25°C between day and night.

Previous cooling systems suffered from:

• Dust accumulation inside fill packs

• High fan failure rates

• Increased maintenance requirements

• Unstable process water temperatures

• Project delays caused by equipment reliability issues

As the EPC contractor was responsible for overall project delivery, equipment reliability and on-time installation were critical requirements.

Solution

CASEN supplied Counterflow Cooling Towers customized for Pakistan's harsh industrial environment.

Advanced Dust Protection

• Multi-stage removable air inlet filtration system

• Reduced dust ingress into critical heat exchange components

• Simplified cleaning and maintenance procedures

Wide Ambient Temperature Adaptability

• Heavy-duty fan motors designed for both high- and low-temperature operation

• Stable performance across ambient temperatures ranging from 5°C to 42°C

Optimized Fill Design

• Counterflow fill configuration engineered to minimize dust accumulation

• Extended maintenance intervals

Accelerated Project Delivery

• Priority production scheduling

• Direct container shipment to Karachi Port

• Complete English technical documentation and simplified Urdu maintenance instructions

Factory Validation

• Simulated dust-load performance testing

• Full operational verification before shipment

Results

The cooling towers were delivered on schedule and successfully commissioned at the first startup.

Project outcomes included:

• 90% reduction in fan-related failures during dust storm seasons

• Stable process water temperature maintained within ±1°C

• Zero production losses caused by cooling system instability

• Project completion without equipment-related rework

• Long-term cooperation established with the EPC contractor
