Customer: Industrial Park Operator

Location: Philippines

Equipment: Closed-Circuit Cooling Tower

Cooling Medium: Recirculating Clean Water

Quantity: 9 Units

A large industrial park located in a tropical coastal region of the Philippines required a reliable circulating water cooling solution for multiple manufacturing facilities. The cooling system serves both central air-conditioning systems and process cooling equipment. Due to the region’s high temperatures, humidity, and salt-laden coastal air, the customer required a corrosion-resistant, low-maintenance solution capable of delivering stable performance year-round.

Challenge

The customer previously operated conventional open cooling towers that suffered from excessive drift loss, unstable outlet water temperatures, and frequent maintenance issues.

Key challenges included:

• High ambient temperatures ranging from 32°C to 38°C year-round

• Severe coastal salt-spray corrosion

• Significant water consumption caused by drift losses

• Unstable cooling performance during peak summer operation

• Need for standardized equipment across multiple workshops

• Limited local maintenance resources

The customer sought a durable and energy-efficient cooling solution that could ensure reliable operation under tropical coastal conditions while minimizing operating costs.

Solution

CASEN supplied nine Closed-Circuit Cooling Towers specifically configured for the local operating environment.

Key design features included:

Enhanced Corrosion Protection

• Magnesium-aluminum-zinc coated heat exchange coils

• Additional anti-corrosion protective coating on the tower casing

• Designed for long-term resistance to coastal salt-spray exposure

Water-Saving Design

• High-efficiency drift eliminators

• Drift loss controlled below 0.001%

• Reduced water consumption and makeup water demand

Intelligent Capacity Control

• Nine towers arranged into three modular operating groups

• Variable Frequency Drive (VFD) fan control

• Automatic cooling capacity adjustment based on thermal load

Simplified Installation & Commissioning

• Containerized export packaging

• Complete English installation manuals and drawings

• Remote commissioning support for local contractors

Reliability Verification

• 48-hour continuous full-load factory performance testing

• Simulated high-temperature and high-humidity operating conditions

Results

All nine cooling towers were successfully commissioned on schedule and entered continuous operation without issue.

After 18 months of operation, the customer achieved:

• 24/7 stable cooling performance throughout the year

• Zero coil corrosion failures or leakage incidents

• 34% reduction in cooling water consumption

• 17% improvement in HVAC cooling efficiency during peak summer operation

• 40% reduction in local maintenance workload

The successful project led to additional discussions regarding cooling equipment supply for future industrial park expansion phases.
