A line of ammonia industrial refrigeration packages ranges from motor-compressor combinations on rails to complete rotary screw compressor packages. The NH3 screw compressors are available in 20-300 hp. They have energy-efficient rotor profiles with advanced geometry and stability. The NH3 reciprocating compressors are available in 5-60 hp (direct drive or belt drive). Water-cooled heads are standard. Both compressors are optimized for parallel operation and have high-quality shaft seals.
