Interested respondents must be able to: Provide standard commercial (cataloged) units that have all of the following features to meet design requirements: Nominal 35-ton cooling capacity, with actual discharge meeting specification air in ambient conditions at or exceeding 111 degrees F dry bulb temperature (see table below for specification air requirements). Minimum 1000 lb/hr purge rate at specification air conditions. Up-blast vertical discharge condenser fans. A pre-cooler upstream of the blower to cool bearings in high ambient temperatures. Provide units with a dual refrigeration circuit system. A variable frequency drive (VFD) on the second-stage compressor for efficient
