Finding the Best Refrigeration Contractors in San Mateo County
Licensed refrigeration contractors in San Mateo County must have have a C-38 license to legally provide refrigeration repair, new commercial refrigerator or freezer installation, handling of refrigerants, refrigerant leak detection and refrigerant charging. Their work includes commercial refrigerator service, commercial refrigerator repair, refrigerated rooms and insulated refrigerated spaces for temperatures below 50 degrees Fahrenheit (10 degrees Celsius).
In California, any refrigeration work of $500 or more requires a C38 licensed contractor. C38 license holders have worked for others for four years at journeyman-level refrigeration work experience; then have passed two licensing exams and purchased bonding and worker's compensation insurance. They are not legally required to have liability insurance; however, all refrigeration contractors bearing the Prime Buyer's Report Top Ten designation have general liability insurance coverage that reimburses customers in the event of any damages. In addition, these certified companies have passed all other requirements for certification as Prime Buyer's Report Top Ten, including customer reference checks, hiring only documented workers, clean complaint record, and more.
Refrigeration contractors in San Mateo County CA most often service commercial and industrial refrigeration clients such as restaurants, grocery stores, food processors, warehouses, dairies, bakeries, meat processors, and other industries that require cold storage.
Types of refrigeration units they service or sell include ice machines, meat lockers, air doors, bar refrigeration, blast chillers, chef bases, commercial freezers, commercial refrigerators, display cases, drop-in refrigeration units, food prep tables, merchandisers, milk coolers, undercounter freezers, and refrigeration accessories. They are usually also able to repair or replace all the main components of restaurant refrigerators and other commercial refrigeration systems, including but not limited to refrigerator compressor repair and compressor replacement.
Commercial Refrigeration Parts & Components
Commercial refrigeration systems and industrial refrigeration systems have five main components:
Refrigerant (A coolant substance that cycles between gas and liquid states to create and maintain cold temperatures in the refrigeration unit)
Compressor (A mechanical unit that compresses gas refrigerant into liquid)
External exchanging pipes (Refrigeration coils that are located outside the refrigeration unit to let pressured hot gas dissipate heat, which causes it to condense into liquid at high pressure)
Expansion valve (A small hole through which the high-pressure liquid is sucked to a lower pressure chamber on the other side where the lack of atmospheric pressure causes it to boil back to a gas)
Internal exchanging pipes (Pipes wherein liquid refrigerant boils in the low pressure and causes the temperature to drop. This makes and keeps refrigeration units cold)
Types of Commercial Refrigerants
Refrigeration contractors in San Mateo County are experienced working with refrigerants, including refrigerant leaks, and refrigerant charging.
Different types of refrigerants used in commercial refrigeration units include:
• CFCs (Chlorofluorocarbons) such as R-11, R-12, R-114
• HCFCs (Hydrochlorofluorocarbons) such as R-22, R-123
• HFCs (Hydrofluorocarbons), such as R-134a. All these refrigerants are halogenated and contain chlorine, iodine, fluorine, astatine or bromine.
Types of Industrial Refrigerants
Refrigerants more often found in industrial refrigeration systems include the following:
R-717 Ammonia (NH3 ) Ammonia refrigerants are more commonly used in industrial refrigeration systems. Anhydrous ammonia is the most common ammonia refrigerant used in industrial refrigeration. Ammonia has excellent heat transfer properties and is more economically priced compared to other commercial refrigerants, and this low cost is one of the main reasons why ammonia is often used in large refrigeration systems. Ammonia refrigerants do not harm the ozone layer, do not contribute to global warming, and are biodegradable.
Carbon dioxide (CO2 or R-744) Carbon dioxide refrigerants have been extensively used in the past and is growing in popularity today. CO2 refrigerants have a low volume as a vapor which helps reduce the size of the compressor necessary. Because CO2 is a high-pressure refrigerant, it may require measures to contain it in the event of an emergency shut down or power outage. CO2 refrigerants do not add to global warming gasses as they're made from CO2 that was captured from and already present in the atmosphere.
Propane (R-290) or Propylene (R-1270) are two other examples of common refrigerants known as hydrocarbons. These are often used in large chemical processing and refinery facilities. In addition to being refrigerants, these two gases are also flammable, and this restricts their use to places that have safety systems such as explosion-proof electrical devices.
R-125 Pentafluoroethane (CHCF5 ) Pentafluoroethane, R-125, is a blend component used in low- and medium-temperature applications. It is nontoxic, nonflammable, and noncorrosive.
The choice of refrigerant to be used for an industrial refrigeration system should be based on the specific requirements of the cooling process. Additional criteria may include safety considerations, operating temperatures, familiarity with the refrigerant and its specific requirements, and accommodation within existing infrastructure. Experienced refrigeration contractors in San Mateo County should be able to help you choose which system is best for your needs.
Refrigeration contractors in San Mateo County will know that each of these refrigerants have their own unique properties and that you should only charge a refrigeration system with the exact refrigerant specified. Use of an incorrect refrigerant can lead to reduced refrigeration efficiency, mechanical problems leading to costly refrigeration repairs, and dangerous conditions.
Secondary Refrigerants These are substances such as air, water, or brine that are not refrigerants in themselves, but have been cooled by the primary refrigeration system to then pass over and around the areas and substances to be cooled; then return with their heat load to the primary refrigeration system. Secondary refrigerants are used where the cooling effect must be moved over a long distance making it cost prohibitive for gas-tight lines to travel that distance.
