How to Maintain Refrigeration and Cooling Systems

Posted by johnpreston on October 26th, 2016

In order to maximize the lifespan of any type of refrigeration or cooling system, preventive maintenance is essential. More often than not, cooling equipment that suddenly breaks down has simply not been maintained properly. Therefore, regular maintaince of cooling systems plays a critical role in keeping repair and replacement costs to a minimum. In general, maintainence of this sort involves examining three major parts of the system: the compressor, condenser, and evaporators.

Maintaining the Compressor

Consider cold plate service Chicago. In order for a business in this industry and this region to keep their operating costs down, maintaining their compressors is paramount. This means checkups every six months, without fail. When examining the system, check all the electrical parts and connections.  Damaged wires should be replaced, and foreign materials must be removed. Any discoloration should also be inspected, as this is usually a sign of a loose wire or worse, an “overcurrent” situation. Likewise, the motor for the defrost timer should be cleaned and lubricated so that it can run smoothly and at the correct speed. Moreover, all pressure controls, especially the ones for high pressure and oil safety, must be checked. Other components that should be inspected are defrost controls, refrigerant line insulation, refrigerant levels, and system superheat. All super hose lines and capillaries should be secure, and missing unit covers and valve caps must be replaced as soon as possible.

Maintaining the Condenser

The condenser is another major component of the process refrigeration service Chicago; it should be cleaned and maintained twice a year. This entails washing and cleaning the condenser coil with either a vacuum cleaner, brush, pressurized water, or coil cleaning foam. Ideally, a combination of those methods will be used to ensure quality results. Additionally, the condenser fans must be inspected for any signs of wear and stress. Each fan should be able to rotate freely, but set screws must remain tightened. If applicable to your particular model, the condensor motors should be lubricated. This is rarely the case, however, as most condensers today are manufactured with their motors permanently sealed. Worn or damaged motors need to be replaced immediately.

Maintaining the Evaporators

Evaporators of cold truck service Chicago must be inspected far more frequently, approximately once every month. This is because when ice accumulates on evaporator coils, it can affect system efficiency, or worse, cause damage to the coil itself. This is especially likely during the lengthy winter season, and as such, means that routine examination is required. Evaporator maintainance hinges on ensuring that all the electrical connections are snug and tightly fastened. Fan blades and motors should also be cleaned regularly; worn blades must be replaced and the set screws tightened. Another important element to check is all defrost heaters. Each must be invidually inspected to confirm that they are in the right configuration; heater terminals should be visually examined to ensure there is no external damage.  Furthermore, the drain pan should be cleaned regularly by flushing all standing water and removing any foreign materials or particulates. Most importantly, the surface of the evaporator coil must be washed and cleaned on this same schedule, to mitigate the risk of any deposits or buildup.

By regularly inspecting, maintaining, and cleaning refrigeration and cooling systems, you extend the efficiency, productivity, and working lifespan of your equipment, and reduce your risk of unplanned costs. In doing so, you maintain your standards of quality and safety in the workplace.
