8 Maintenance & Renovation Carrier Commercial Without proper service procedures, even the highest quality technology equipment cannot be guaranteed to work in a continually optimal state. In addition to standard service contracts Carrier can deliver specific maintenance, system enhancements, and modernization in accordance to customer requirements. Carrier Commercial Refrigeration Call Center Refrigerant leak detection Leaking units dramatically increase a system s power requirement, and therefore energy consumption. If the refrigerant partly escapes due to a leak, optimal temperatures cannot be reached even if the energy use is increased. In line with European laws the Carrier service package includes regular leak detection tests to reduce the emission of greenhouse gases. Heat exchangers service Layers of dirt on evaporators and condensers prevent effective heat transfer. Heat transfer efficiency falls and energy consumption increases. Dirty refrigerated display cases are not only unhygienic and inefficient; they also cause operating faults impacting the refrigeration system s proper operation. Cleaning services are highly recommended Energy enhancements in Carrier cabinets: insulated glass doors, LED lighting, improved evaporator and fan efficiency to keep your refrigeration system operating at peak performance. Maintaining the quality of oil Constant operation of a food retail refrigeration system places the highest demands on the properties of the lubricants. If the oil and filters are not replaced regularly, dirt and particle friction will cause damage. Oil sample analysis enables accurate detection of degrading lubricants. Carrier maintenance not only provides proper exchange cycles for oil and filters, but also ensures that the best possible machine oil is used. Energy optimization Using data collected online with e*services, Carrier can analyze the energy efficiency of your refrigeration system and make recommendations for improvements.
