DM Series Water refrigeration condensing unit The DM series, developed by our company, utilizes a highly integrated design concept. By consolidating the compressor, water-cooled condenser, piping, and necessary accessories into a compact, all-in-one structure, these units serve as the primary refrigeration core for cold storage systems.
The open-frame design facilitates easy installation while reducing the overall cost of the condensing unit. The product line is categorized into three types: medium-temperature units (0°C to 10°C) for applications such as fruit and vegetable preservation; low-temperature units (-15°C to -18°C or -18°C to -23°C) for the frozen storage of meat, seafood, and similar products; and ultra-low-temperature quick-freezing units, designed for the rapid freezing of items like seafood and dried fruits.
These units are equipped with high-performance, reliable compressors from industry-leading brands, including Bitzer (piston compressors) and Copeland.
Furthermore, the units feature a condensate recovery and utilization function, which effectively lowers the condensing temperature and significantly enhances operational efficiency. Designed for ease of installation and maintenance, these units also offer substantial cost savings and are ideal for locations with an abundant water supply.
