From the food industry to general water and structure cooling, refrigeration and chillers are available for a wide market of purposes and uses. Since these are such prevalent pieces of equipment in both commercial and industrial construction, several types of models exist for prospective buyers to consider.When considering modes of refrigeration and chillers, consider your business' needs and purposes. Food services and other small- to moderate-scale businesses needing refrigeration services should buy commercial refrigerators and freezers or small chillers. Large-scale uses, such as water or air conditioning for large areas, require the capabilities of HVAC chillers. When shopping for units, determine which of the following usages is best for your needs:1. Preserve food in commercial fridges and large refrigeration and freezer units.2. Purchase HVAC chillers from suppliers of industrial chillers.3. Fix broken units by replacing the refrigeration compressor component. Store food supplies for your business with heavy duty refrigeration and chillers The food service industry relies heavily on the capabilities of commercial refrigeration services. Common food storage units include large-scale refrigeration and chillers for food storage, as well as deep freezers for long-term preservation. Cool large spaces or amounts of water with an industrial chiller Industrial chillers, including the HVAC chiller, use compressed water or air to cool an output supply of air or water at normal pressure conditions. Businesses generally use high-caliber industrial chillers for large-scale purposes only. Such applications range from air conditioning to water cooling systems. Replace the refrigeration compressor in your cooling unit Industrial chillers are large units which use compressed gases as a cooling agent. Ammonia is a common gas associated with the purposes of industrial chillers. If your chiller's systems are operating fine but no cool air is exiting the unit, you may need to replace your refrigeration compressor. Save on equipment costs with used fridges and industrial chillers Used refrigeration services cost considerably less than new models. The technology of refrigeration changes sparingly, so you can purchase relatively older units without missing important features or safety concerns. When buying new or used commercial chillers or compact refrigerators, purchase an extended warranty if possible. Don't risk losing out on a large investment if the unit is faulty or a lemon. If you purchase a used unit, be sure it complies with emissions standards. Some older models emit ozone-depleting models which severely harm the environment if not kept up-to-date.
