Coils--Continuous-tube down-draft fin-coils are still first choice for meat coolers, or other products requiring high humidity and gentle air circulation. Ceiling Diffuser--Ceiling diffusers distribute the cooled air across the ceiling, so the draft does not strike the products stored or occupants. C. F. Coils--Continuous nn coils for unit coolers, blast heaters, air conditioning and condensers. Shell Condenser Evaporative Condensers Floor Units Air Conditioning--Air Conditioning units of ceiling or floor type in all capacities, for cooling, heating, or both. Shell Condenser--Shell and tube, also shell and fin coil condensers. Evaporative Condensers--Evaporative condensers from 2 to 100 tons. Brine spray cooling to 25 tons.
