Small Cold Room Evaporator

Product Advantages

Compact Structure & Space-Saving Design

This small cold room evaporator is specially developed for limited-space cold storage scenarios, making it ideal for mini walk-in coolers in convenience stores, small catering back kitchens, and community fresh food shops. Its compact body takes up minimal ceiling space, avoiding occupation of valuable storage area inside the cold room. The shell is made of high-quality galvanized steel sheet with plastic-sprayed surface, which has excellent corrosion resistance and a neat appearance, adapting well to the humid environment inside medium-temperature cold rooms. The smooth surface is not easy to accumulate dust, which facilitates daily cleaning and meets the hygienic requirements of food storage scenarios.

High-Efficiency Heat Exchange Core Technology

Built with industry-leading heat exchange structure, this G6 series evaporator adopts internally threaded copper coils with staggered arrangement, which increases the internal heat exchange area and reduces oil film coefficient, greatly improving overall heat transfer efficiency. The fins use a louvered design with double sine wave shape and corrugated edges, further enhancing heat transfer performance. With 4.5mm fin spacing optimized for medium-high temperature working conditions, it maintains stable heat exchange efficiency while slowing down frost accumulation, reducing the frequency of defrosting cycles. Each unit undergoes a 2.8MPa pressure test with clean air before leaving the factory, ensuring stable and leak-free operation for long-term use.

Reliable Operation & Low-Maintenance Performance

Equipped with a low-temperature resistant external rotor motor, this small cold room evaporator features high operating efficiency, large air volume and low noise, which will not cause noise disturbance to the surrounding working environment. The motor has an IP55 waterproof rating and F-class insulation grade, with an applicable temperature range of -40℃ to 60℃, ensuring stable operation even in fluctuating cold storage environments. It adopts electric defrosting with stainless steel heating tubes, equipped with insulated joints and ultra-low temperature epoxy resin wires, and a separate defrosting heating tube is installed on the water tray to ensure thorough defrosting and smooth drainage. It is compatible with multiple refrigerants including R507A, R404A, R134a and R22, which can flexibly match different refrigeration unit configurations.

Frequently Asked Questions

Q: Is this small cold room evaporator suitable for a mini walk-in cooler in a convenience store?

A: Yes, the D3.5E4.5 model is designed for small and medium-temperature cold rooms around 0℃, with a compact ceiling-mounted structure that does not take up storage space. It is very suitable for mini walk-in coolers in convenience stores, small catering back kitchens and fresh food stores for beverage, fruit and vegetable storage.

Q: What does "E4.5" mean in the model number?

A: In the model naming rule, "E" stands for electric defrosting method, and "4.5" stands for 4.5mm fin spacing, which is optimized for medium-high temperature cold storage working conditions. We also provide other defrosting methods (air, water, hot gas) and fin spacing options to match different temperature requirements.

Q: What refrigerants are compatible with this evaporator?

A: This series of evaporators supports a wide range of refrigerants, including R507A, R404A, R23, R134a and R22, which can flexibly match different brands and types of condensing units. You can inform us of your refrigerant requirements when placing an order.

Q: What is the waterproof and insulation grade of the fan motor?

A: The external rotor fan motor is equipped with IP55 waterproof grade and F-class insulation grade, with an operating temperature range of -40℃ to 60℃. It has good adaptability to the humid and low-temperature environment inside the cold room, and has a long service life with low failure rate.

Q: Do you provide matching condensing units for this evaporator?

A: Yes, we can provide a complete set of cold room refrigeration solutions, including matching condensing units, evaporators and supporting accessories. You only need to provide your cold room size, storage temperature and cargo type, and we will match the most suitable configuration for you.
