Difference Between Top and Bottom Mounted Cabinet

Choosing between a commercial refrigerator with the compressor located on top or at the bottom goes beyond just the placement. It has a significant impact on the functionality, utilization of space, and maintenance. Understanding these differences is key to making a decision for your business.

All of its refrigeration system mounted above the internal storage area.

PROS

Efficiency – In a top-mounted system, the heat that the compressor generates is expelled outside the unit rather than into the box. This can lead to better cooling performance and energy efficiency.

Less Susceptible to Dirt – Being elevated, top-mounted systems are less prone to drawing in dirt and debris from the floor, potentially improving the system's cleanliness and longevity.

Long-lasting – The safety of your bottom mounted unit during cleaning may be compromised if your cleaning crew does not exercise proper care. In contrast, The top mounted unit remains safely unaffected and out of harm's way.

Space Utilization – A top mount unit provides more interior space since there is no need for accommodation of refrigerant lines or insulation above the condenser.

CONS

Maintenance Difficulty  - Despite being accessible for service, some maintenance tasks might be more challenging due to the height. Technicians might need ladders or other equipment to reach the top-mounted unit, potentially increasing the labor and time required for repairs or maintenance.

Heat Accumulation  - While top-mounted units utilize rising heat for dissipation, in spaces where there's a lot of heat already present (like hot kitchens), it might add to the overall heat load, potentially affecting the system's efficiency.

Ceiling Height Consideration  - In areas with low ceilings, a top-mounted system might not be practical due to clearance requirements, limiting installation options.  

All of its refrigeration system mounted on the bottom with the internal storage area sitting on top.

PROS:

Efficiency  - In a hot kitchen, the floor tends to be the coolest area than the hot zone near the ceiling which a bottom-mounted unit would work more efficiently. In addition, there might less impact on the ambient temperature, especially in areas where additional heat accumulation can be a concern.

Maintenance Accessibility  - Technicians are able to service or maintain the refrigeration components easier without the need for ladders or specialized equipment to reach high spaces.

Less Cleaning – Airborne grease and steam cannot infiltrate your refrigerator, leading to less frequent coil cleaning and improved operational efficiency.

Ease of Access for Refrigerated Items  - Bottom-mounted systems place the refrigerated compartments at eye level or within easier reach, making it more convenient for users to access frequently used items without bending or stooping. 

CONS:

Potential Dust and Debris Accumulation – Being closer to the floor, these systems might draw in more dust, dirt, and debris, potentially impacting the cleanliness and maintenance requirements.

Space Constraints – The bottom-mounted compressor and condenser units might occupy space that could have been used for storage or other purposes in some configurations.

Temperature Fluctuations – The mechanical components of the refrigerator can generate heat that rises into the cabinet, which ultimately reduces the amount of energy required to maintain the temperature.
