Project Overview

Customer: Compressor Package Supplier
Location: South Africa
Equipment: Evaporative Condenser
Refrigerant: R717 Ammonia
Quantity: 2 Units

A South African refrigeration system supplier required evaporative condensers for a large livestock cold storage facility utilizing an R717 ammonia refrigeration system. The project demanded a highly reliable solution capable of operating safely under hot, dry African climate conditions while meeting strict ammonia refrigeration safety standards.

Challenge

The customer supplies complete compressor packages to cold storage operators across South Africa.

Key project challenges included:

• High summer temperatures reaching 35°C and above

• Strict ammonia refrigeration safety requirements

• Corrosion risks associated with ammonia exposure

• Stable condensing pressure requirements for large cold storage facilities

• Compliance with local refrigeration safety regulations

Conventional condensers designed for fluorocarbon refrigerants were unsuitable for long-term ammonia service.

Solution

CASEN supplied two Evaporative Condensers specifically engineered for R717 ammonia refrigeration systems.

Ammonia-Compatible Construction

• Stainless steel coils and headers designed for ammonia service

• Reinforced welding and sealing technology

• Enhanced corrosion resistance

Explosion-Protected Components

• Explosion-proof motors and electrical components

• Suitable for ammonia refrigeration environments

High-Efficiency Heat Rejection

• Expanded heat transfer surface area

• Optimized performance under hot and dry climatic conditions

• Stable condensing pressure control

Compliance Support

• Comprehensive English ammonia safety documentation

• Technical assistance for local regulatory submissions

Leak-Free Verification

• Factory pressure testing and leak detection procedures

• Zero-leak certification before shipment

Results

The condensers integrated seamlessly with the customer's compressor packages.

Project benefits included:

• Stable condensing pressure throughout annual operation

• Zero ammonia leakage incidents during the first 12 months

• Zero corrosion-related failures

• 21% improvement in refrigeration heat rejection efficiency

• 16% reduction in overall refrigeration power consumption

• Successful completion of local safety inspections

The customer subsequently standardized the KEG Series as part of its preferred refrigeration equipment portfolio.
