Conversely, a system that is poorly maintained and prone to leaks or operational issues not only poses a significant safety risk but also suffers from degraded performance and increased energy consumption. Regular, professional maintenance and a proactive approach to safety are the cornerstones of a high-performing system.
• Essential Maintenance Points: To ensure both safety and efficiency, the following maintenance tasks are crucial:
  • Leak Detection: Even a small refrigerant leak can dramatically reduce system efficiency. Regular and precise leak detection using advanced sensors is essential to prevent both safety hazards and energy waste.
  • Pipe and Component Cleaning: Accumulations of oil, scale, and other contaminants within the system's pipes and heat exchangers reduce heat transfer efficiency, forcing the compressor to work harder and consume more power. Regular cleaning and flushing are non-negotiable for maintaining peak performance.
  • Pressure Calibration: Maintaining optimal operating pressures is vital. Incorrectly calibrated gauges or controls can lead to the system working outside its most efficient range. Regular calibration checks ensure the system operates within its designed parameters, preserving both safety and energy performance.
  • Ventilation System Check: Proper ventilation is a critical safety feature of any ammonia plant. Ensuring that emergency ventilation systems are in perfect working order not only mitigates safety risks but also indirectly supports efficiency by ensuring the system is not hindered by environmental factors.

The contrast between a system with and without dedicated safety maintenance reveals a clear picture of performance.
