This D4.9E4.5 cold room evaporator is engineered with premium internally threaded copper coils in staggered arrangement, which effectively expands the internal heat exchange area and reduces oil film coefficient, maximizing heat transfer efficiency and cooling output. The fins adopt louvered double sine wave design with corrugated edges, further optimizing air flow and heat exchange effect.
With 4.5mm fin spacing optimized for medium-high temperature working conditions, it maintains stable cooling performance while slowing down frost formation, reducing defrost frequency and energy consumption. Each unit undergoes a 2.8MPa pressure test with clean air before delivery, guaranteeing leak-free and reliable long-term operation.
Equipped with a low-temperature resistant external rotor motor with 180W power, this evaporator delivers large air volume of 3900m³/h with high operating efficiency and low noise, suitable for various commercial and industrial cold room environments.
The motor features IP55 waterproof rating and F-class insulation, with an operating temperature range of -40℃ to 60℃, ensuring stable performance even in harsh cold storage conditions. It adopts electric defrost with stainless steel heating tubes, matched with insulated joints and ultra-low temperature epoxy resin wires. A separate defrost heating tube is installed on the water tray to ensure thorough defrosting and smooth drainage, avoiding ice accumulation and maintaining consistent cooling efficiency.
The evaporator shell is made of high-quality flat galvanized steel sheet with high-grade plastic-sprayed surface, providing excellent corrosion resistance and long service life in humid cold room environments. The middle tube sheet adopts high-quality aluminum material, with compact structure between copper tubes and tube sheets, reducing the overall installation space.
With ceiling mounted design, it saves valuable floor storage space inside the cold room, especially suitable for cold storage with limited space. The product also supports material options including 304/316 stainless steel and aluzinc sheet, to meet different application requirements of food processing, pharmaceutical and other industries.

Ruifujie is a professional refrigeration equipment manufacturer with more than 20 years of experience in the global cold chain industry. We specialize in producing a full range of refrigeration products, including scroll, piston, rotor, semi-hermetic and screw refrigeration compressors, as well as complete cold room systems, quick-freezing equipment and ice making machines.
Our products are widely exported to the United States, Australia, Germany and many other countries and regions. With strong R&D capability, strict quality control and competitive pricing, we have established long-term stable cooperative relationships with customers worldwide and won widespread recognition and trust.
This model is designed for medium-high temperature cold rooms with 0℃ room temperature, widely used for fresh-keeping storage of fruits, vegetables, beverages, dairy products and other food materials. It is ideal for small and medium-sized commercial cold rooms in supermarkets, catering businesses, fresh food stores and food processing workshops.
This evaporator supports multiple common refrigerants, including R507A, R404A, R23, R134a and R22, which can flexibly match different types of condensing units. You can inform us of your refrigerant requirements when ordering, and we can make corresponding adjustments according to your needs.
In our product naming system, "E" represents electric defrost method, and "4.5" represents 4.5mm fin spacing, which is specially optimized for medium-high temperature cold storage conditions. We also provide other defrost methods (air, water, hot gas) and fin spacing options for different temperature requirements.
Yes, we can provide complete cold room refrigeration solutions, including matching condensing units, evaporators and all supporting accessories. You just need to provide your cold room size, required storage temperature and cargo type, and our professional team will recommend the most suitable configuration for you.
All our cold room evaporators come with a standard quality warranty. We provide comprehensive after-sales support, including technical guidance for installation and use, and spare parts supply. For bulk purchase customers, we also offer exclusive after-sales service and preferential policies.
We support both sample trial orders and bulk wholesale purchases for this D4.9E4.5 cold room evaporator, with competitive factory direct prices. For engineering contractors, chain store operators and cold storage equipment dealers, we provide exclusive wholesale discounts and customized services including material selection, voltage customization and logo printing.
