Established as a premier global supplier, Shandong Linru Import & Export Trading Co., Ltd. (also operating with production excellence via Feijin Import & Export) represents over 15 years of industry-leading research, manufacturing, and distribution of commercial kitchen solutions. Starting from custom kitchen stoves, our growth trajectory is built upon strict adherence to engineering standards. We firmly reject the race-to-the-bottom pricing models that compromise unit longevity. Instead, we implement complex refrigeration system layouts, heavy-duty structural designs, and strict compliance tests for major international markets.
Our products, from electrical stoves to commercial cooling components, carry full-range CCC (China Compulsory Certification). Our pressurized boilers and jacketed kettles hold the respected National Pressure Vessel Manufacturing License.
Feijin’s stainless-steel preparation equipment is built using high-grade 304 or 201 stainless steel, ensuring excellent resistance to pitting corrosion and acid erosion while offering outstanding load-bearing capacity.
We match technical parameters—including capillary sizing, evaporator coil surface areas, and compressor capacities—to your exact geographical climate zones and local code specifications.
In commercial refrigeration, a Sandwich Preparation Table is much more than a refrigerated storage box with a cutting board. It is a highly engineered thermodynamic workstation. Its primary engineering challenge is maintaining uniform cold storage temperatures (between 33°F and 40°F / 0.5°C and 4.4°C) in two distinct zones simultaneously: the enclosed lower cabinet and the open-top ingredient pans exposed to ambient kitchen heat.
Most cheap prep tables struggle with "temperature stratification"—where warm air rises, leaving the top pans vulnerable to food safety violations, while the lower shelves freeze delicate leafy greens. Feijin engineers address this by designing customized forced-air cooling circuits. By creating an insulated cold air barrier, or "air curtain," across the open top, warm ambient air is deflected. At the same time, high-density cyclopentane-blown polyurethane foam insulation (at least 2 inches thick) isolates the internal cabinet from extreme external kitchen heat, which can exceed 100°F (37.8°C) near fryers and ovens.
In fast-casual QSRs (Quick Service Restaurants), delicatessens, and institutional salad bars, speed and food safety are key. A poorly designed sandwich prep table slows operations and compromises sanitation. Our macro-level solutions focus on three main design requirements:
Traditional static cooling systems fail under heavy, continuous use. Our forced-air system uses high-speed, energy-efficient EC (Electronically Commutated) fans to circulate cold air through engineered duct paths. This ensures fast temperature recovery even during busy lunch rushes when the pan lids are constantly open.
We locate our condensing units either on the side or rear, using removable front grilles. This design prevents flour and cooking grease from clogging the condenser coils, reducing compressor strain and extending the table's service life.
Exporting refrigeration equipment worldwide requires compliance with varying local standards. As a leading manufacturer in China, Shandong Linru ensures that each wholesale prep table is certified and configured for the specific destination country:
Units destined for North America are built to meet NSF/ANSI Standard 7 for open-top prep tables, which requires maintaining safe temperatures in ambient conditions of up to 86°F. Electrical configurations are designed to meet UL 471 standards (115V/60Hz/1Ph) and feature NEMA 5-15P plugs.
Our European models feature environment-friendly hydrocarbon refrigerants like R290 (Propane) to comply with F-Gas regulations. Electrical components are CE and UKCA certified, operating at 230V/50Hz with standard Schuko or UK plugs.
For hot, humid climates, we configure systems with heavy-duty, tropicalized compressors (climate class 5, capable of operating in ambient temperatures up to 43°C/109°F) and oversized condenser coils to ensure reliable cooling.
To back up this international support, Shandong Linru maintains a robust supply network for replacement parts, including digital controllers, fans, and replacement gaskets. We partner with local distributors and commercial refrigeration technicians worldwide, providing detailed wiring diagrams, troubleshooting guides, and quick dispatch of warranty components to minimize downtime.
Commercial refrigeration is shifting rapidly toward sustainability, precise digital control, and smart diagnostic monitoring. Shandong Linru is leading this transition by integrating advanced technologies into our manufacturing pipeline:
Transitioning away from high-GWP HFCs (like R404A) to R290 hydrocarbon refrigerant. This natural refrigerant has a Global Warming Potential (GWP) of just 3 and improves thermodynamic efficiency by up to 15%.
Optional smart modules with Bluetooth and Wi-Fi connectivity. Kitchen operators can track temperatures in real time, log HACCP compliance data automatically, and receive instant alerts for system issues.
Instead of using basic timed defrosts, our system monitors evaporator coil temperatures and runs defrost cycles only when frost build-up is detected, saving energy and maintaining stable storage temperatures.
Magnetic, press-in drawer and door gaskets that can be replaced without tools. This ensures a tight seal is maintained over time, reducing energy loss and simplifying routine maintenance.
