Lab Refrigerators with top-mounted compressors vs. bottom mounted compressors
Lab and pharmacy refrigerators with top-mounted compressors are commonplace in the market today. We make both top and bottom mounted versions in cabinet sizes we offer, but for quiet operation and energy efficiency, bottom mounted models are the best choice. Placing the compressor under the cabinet storage area insulates its running noise from the ears of those nearby, while top-mounting it puts it at ear level and bounces noise off the ceiling, as well. Bottom mounting takes advantage of gravity to drain condensation from the cooling coils inside the chamber to the evaporative compressor, while electricity must be used to pump or evaporate condensate when the compressor is on top. With concern for energy efficiency driving lab equipment purchases, these are important distinctions.
