New M-Series high-ambient condensing units are designed to provide dependable refrigeration in the hottest environments, the manufacturer says. They are available with most of the company’s new walk-in coolers and freezers, or they can be ordered as a retrofit. Larger fan motors and blades mean greater airflow through the condenser and across the compressor. Large-capacity condensers take advantage of the increased airflow and boost performance. Models range from 1/2 to 6 hp with a variety of temperature ranges and several compressor options.
