Roll-in refrigerators can be an afterthought, since these units are not as interactive as other types of equipment.
Although equipment like roll-ins require minimal interaction, other than opening and closing the door, these units operate 24/7 and receive heavy usage in foodservice operations.
With its basic construction, the service life of a roll-in depends on how well the compressor is cared for and the environment that it's used in.
There are a number of warning signs that a unit needs replacing.
Compressors producing excessive noise or rattling sounds: If service calls are not taking care of the problem, the compressor may be old and tired. A noisy unit may indicate that the roll-in is ending its service life.
Temperature issues: This can result in food replacement, which is costly. Consequently, if temperatures inside the unit are fluctuating extensively, this could mean the roll-in is beyond repair.
Excessive wear: If door hinges are pulling away from the cabinet, seams or welds are broken and/or insulation is exposed, this may signify that a new unit is needed.
Increased service calls and high repair costs: Roll-in refrigerators can last 10 years at the minimum, or as long as 30 years with proper maintenance. If the unit is older, and service calls are becoming more numerous and costly, replacement most likely is warranted.
