Distributed Scroll System

Reduced Refrigerant Charge. Ease of Installation. Accessibility.The redesigned Distributed Scroll System from Kysor/Warren includes an environmentally friendly design offering reduced refrigerant charge and leak potential. The enhanced space-saving design allows for ease of installation and accessibility in one product solution for supermarkets. This innovative system significantly reduces refrigerant charge when applied near refrigeration loads.

Reduced Refrigerant Charge and Leak Potential

■ Up to a 70% reduction in refrigerant charge as compared to a traditional centralized rack system

■ Features a 35% reduction in brazed joints compared to previous models, drastically reducing the potential for leaks

Ease of Installation and Operation

■ Maximizes merchandising space by eliminating need for a machine room

■ Reduction of field braze joints means easier installation (less brazing and pipe work) and reduced leak potential

■ Additional units can be added to existing facilities

Ease of Accessibility

■ Sliding side doors allow for ease of servicing ■ Hinged front doors provide easy access to compressor and electrical components

■ Easily combined with a Kysor/Warren Condenser Assembly to provide a complete high-side refrigeration system solution

Energy Efficient Design

■ Features energy efficient Scroll compressors ■ Optimal grouping of systems to more closely match suction temperature requirements

The refrigerant reducing Distributed Scroll System is an innovative product solution from Heatcraft that significantly improves the total Life Cycle Climate Performance (LCCP) of refrigeration systems, helping our customers become better environmental stewards.
