The original Hussmann Protocol units held a maximum of 6 compressors. The new 8 compressor unit will allow you to pack more refrigeration capacity into a single horizontal enclosure. This gives you greater horsepower with less floor space required than with two units. 

Environmental Benefits Compared to Traditional Rack Systems:

• Better energy efficiency reduces use of fossil fuels and air pollution
• Significantly smaller refrigerant charge reduces use of HFCs
• Significantly lower refrigerant leak rate reduces HFCs in the atmosphere

All These Factors Combine for a Lower Carbon Footprint and a Reduction in Global Warming
