Refrigeration Condensing Units
Our “D & DD” condensing units are specifically designed commercial and industrial refrigeration duty applications. These units are designed to operate in adverse conditions and meet the needs of the customer with minimal changes to the basic design. These units are designed to operate in high and low ambient conditions. High ambient and high altitudes are not a problem and can be addressed with minimal changes to the basic design to meet your needs. These units come with the components mounted and wired to reduce field installation costs and additional work before installation. Any options to the basic package are mounted and wired as required reducing field labor. The condensing units have vertical air flow with updraft high velocity fans.
Our ‘DM’ Series unit is designed to meet the demands of multiple load applications required for commercial and industrial refrigeration. These multiple compressor units bridge the gap between individual systems and large multiple compressor rack systems for the warehouse industry. The “DM” series allows the compressor rack to be removed from valuable floor space in the facility.
