The D3.6E9 is a high-capacity, ceiling-suspended industrial evaporator designed specifically for deep-freeze storage facilities maintaining temperatures around -35 °C. Equipped with dual 400 mm low-temperature external rotor fans, this unit delivers an impressive air volume of 7800 m³/h (2*3900 m³/h) with a powerful 10-meter air throw. The dual-fan design is ideal for rectangular or deeply packed cold rooms, driving consistent air circulation across all storage racks to eliminate temperature layering and ensure rapid pull-down.
Operating at deep sub-zero evaporating temperatures (down to -42 °C) creates a high-humidity environment prone to rapid frost formulation. To maximize operational uptime, the D3.6E9 features an extra-wide 9.0 mm fin spacing (3 FPI). This wide gap allows substantial frost buildup without blocking critical airflow channels, keeping your refrigeration cycle active longer. The inner-grooved copper tubes are mechanically expanded into double-sine wave aluminum fins, ensuring 100% tight metal-to-metal thermal contact for maximum heat transfer.
To handle aggressive moisture levels, the evaporator housing is fabricated from high-durability prepainted steel sheets, supported by aluminum internal tube sheets for long-term corrosion resistance. A heavy-duty 4.2 kW electric defrost system features stainless steel heating elements distributed through both the coil block and the drain pan, ensuring complete ice clearing with a rapid cycle time. Every unit is subjected to a rigorous 2.8 MPa dry-air pressure test at the factory to guarantee leak-free field operations with low-temperature refrigerants.

Ruifujie has built an international reputation as a specialized manufacturer of cold chain thermal management systems and heavy-duty refrigeration machinery. Operating modern production workshops, we develop and fabricate high-efficiency industrial air coolers, evaporators, condensers, and commercial compressor units. Our technical engineering team works continuously to integrate cutting-edge thermodynamic designs with rugged mechanical construction. By prioritizing strict material selection, advanced tube-expansion technologies, and thorough safety testing, we ensure long-term, trouble-free operation for global engineering contractors, cold storage builders, and refrigeration distributors.
In-line layouts allow a portion of the passing air to slide straight through the coil without touching the cold tubes, which results in thermal bypass and lost efficiency. The staggered tube layout in the D3.6E9 acts as a physical barrier, forcing the air into a winding path. This ensures continuous, direct physical contact with the copper pipes, maximizing the heat extraction rate.
In deep-freeze systems, compressor oil naturally migrates into the evaporator and coats the inside of smooth tubes with an insulating oil film, reducing heat transfer. The internal micro-grooves inside our copper tubes create high-speed refrigerant turbulence that continuously strips this oil film away. Additionally, the grooved structure multiplies the internal surface area, allowing more refrigerant to evaporate per second.
Refrigeration systems undergo severe thermal expansion and contraction as they cycle between cooling (down to -42°C evaporating temperature) and electric defrosting. This continuous expansion can cause joint fatigue and micro-leaks over time. Testing every single evaporator at 2.8 MPa using clean, dry air ensures the ultimate integrity of every copper bend and tube-to-sheet joint. This test pressure is significantly higher than the standard operating pressures of low-temperature refrigerants like R507, guaranteeing years of leak-free performance.
We do not enforce any minimum order quantity (MOQ) for in-stock inventory, allowing you to order single replacement units. For mass-production orders, the MOQ is fully negotiable.
Yes. We provide comprehensive OEM customization services, including the production of custom logos and multilingual nameplates tailored directly to your local regional requirements.
Ruifujie offers competitive, tiered pricing for cold room contractors, engineering firms, and commercial refrigeration distributors. If you are designing a low-temperature storage project and need technical layouts or bulk pricing, send over your room dimensions and local voltage standards. Our technical sales team will provide a tailored hardware match and an official commercial quote within 8 hours.
