Reliable Cold Room Evaporator Supplier in China
When selecting a cold room evaporator, price matters less than compatibility with your operating conditions. Wrong selection means slow cooling, frequent frost, and higher compressor load.
HeShun is a trusted cold room evaporator supplier with over a decade of cold storage experience and thousands of projects. Whether you need a unit cooler for chilled storage or an industrial cold room evaporator for blast freezing, we match fin spacing, defrost method, and specs to your temperature and product. Dimensions, voltage, and mounting can be customized; we also offer integrated packages with a compressor and condenser.

Cold Room Evaporator Types & Selection Guide
Designed for cold storage (0°C to +10°C). Features 4mm fin spacing for efficient heat exchange. Standard electric defrost. Suitable for fruit, dairy, and pharmaceutical cold rooms.
Primary model for freezer applications (-10°C to -25°C). Provides balanced airflow resistance under frosting conditions and stable cooling performance. Standard electric defrost; hot-gas defrost available.
Designed for blast freezing applications (-25°C to -45°C). Wide fin spacing helps prevent airflow blockage under heavy frost conditions. Standard hot gas or water defrost.
Aluminum tubes and fins, natural convection, no fans.. Ideal for long-term storage and applications sensitive to moisture loss.Suitable for ammonia systems. Ceiling-mounted design with low energy consumption and silent operation.

For small cold rooms—say under a hundred square meters—electric defrost is the simplest, cheapest option for a cold room evaporator. For larger rooms, hot gas defrost makes more sense because it uses heat from the compressor instead of drawing extra power. If you’re running a high-humidity operation like a seafood freezing room, water defrost is fastest; the frost just washes off.
Quick rule: electric for small cold room evaporators, hot gas for big ones, water for wet environments.
Go with a unit cooler if you need fast cooling, open the doors a lot, or don’t have ceiling space for hanging coils. Go with an aluminum tube cold room evaporator if you’re worried about product drying out (it cuts moisture loss by 1–2%), want to save on fan electricity, or run an ammonia system. Large cold rooms can mix both types of cold room evaporators.
Yes. We’ve paired our cold room evaporators with Copeland, Bitzer, Danfoss, and most other common systems. Tell us what you’re running, and we’ll confirm compatibility.
Yes. We’ll build your cold room evaporator around your cold room size, temperature, cooling load, and where it’s being installed.
