Introducing the D series air cooler, an exceptional range of indoor cooling equipment designed to seamlessly integrate with condensing units for all types of cold rooms. Tailored to meet varying temperature requirements, the D series is expertly divided into three sub-series: DL, DD, and DJ, each engineered to provide optimal cooling for specific temperature ranges. The DL air cooler, ideal for environments around 0ºC, is primarily used for fresh-keeping cold storage, ensuring that perishable goods maintain their freshness. For more demanding cold storage needs, the DD air cooler operates efficiently at temperatures around -18ºC, making it perfect for preserving frozen goods. Lastly, the DJ air cooler is your go-to solution for extreme cold, functioning at temperatures as low as -25ºC to -30ºC, specifically designed for blast freezer rooms. This ensures rapid temperature reduction for goods that require deep freezing.
