Master-Bilt’s Glycol Parallel Rack System

Master-Bilt’s Glycol Parallel Rack System has multiple compressors that only run when necessary, maximizing efficiency and saving on energy costs. When the system determines that another compressor is needed to handle higher workload, another compressor kicks in. Many times, only one compressor is needed for off-peak hours, while still maintaining proper food safe temperatures for all your refrigeration equipment. When performance is needed during peak hours, more compressors turn on to keep up with the demand for extra cooling capacity.

The use of ethylene glycol is circulated through a loop, typically copper or ABS piping, to cool refrigeration equipment. Return lines carry heated glycol from each piece of equipment back to the remotely mounted rack system for re-cooling.

Along with energy savings, is a reduced refrigerant charge which is completely contained within the wall of the parallel rack system. This means that only the chilled glycol is distributed to the kitchen. Less refrigerant and piping mean less chance of refrigerant leaks. Further, ethylene glycol is nontoxic and deemed a “greener” more environmentally friendly solution.

The most unique feature of the Master-Bilt Glycol System is its floating heat pressure technology that lowers the energy consumption of the refrigeration system by as much as 25%. The system also uses full digital controls vs. mechanical controls in competitive equipment. These state-of-the-art digital controls provide greater precision, diagnostics, data logging and monitoring capability.
