Overview of air-cooled low-temperature chiller (freezer)
The air-cooled low-temperature freezer (chiller) developed by Nuobing Refrigeration is one of the company's flagship products. It is manufactured using the internationally renowned American brand Gulun and Danfoss compressors, as well as world-class electronic control components. It is equipped with a shell and tube condenser and evaporator made of high-efficiency heat exchange copper tubes. Introducing advanced design concepts and processing techniques from Europe and America, the air-cooled low-temperature freezer (freezer) has an overall beautiful appearance, compact structure, excellent and stable performance. The lowest temperature of the air-cooled low-temperature freezer (freezer) can reach minus 120 ℃ or above.
◆ Built in stainless steel water tank. High performance, high flow dedicated water pump;
The NBA * * ADZT series air-cooled low-temperature chiller (freezer) has two independent refrigeration systems that can automatically adjust the number of systems involved in operation according to load changes, thereby achieving maximum energy savings. The two systems can also serve as backups for each other, providing higher reliability.

The air-cooled low-temperature freezer (freezer) can use ethylene glycol or calcium chloride solution as the refrigerant. The outlet temperature of chilled water can be controlled above -120 ℃;
Nuobing Refrigeration can customize environmentally friendly refrigerants such as R134a, R407C, R404A, and corrosion-resistant products from seawater sources according to customer needs.
The condenser adopts high-efficiency heat exchange threaded tube string hydrophilic aluminum foil fins, precision mechanical tube expansion, excellent processing, H-shaped structural design, equipped with high-quality fans, uniform wind speed, low noise, and high heat exchange efficiency;
The evaporator of the air-cooled low-temperature freezer (freezer) adopts high-efficiency threaded copper pipes, the latest CAD/CAM design and processing technology, and is matched with a CNC machining center. The evaporator is fully automatically expanded by computer numerical control, with a small volume and high heat transfer efficiency;
High precision digital controller, capable of intuitively and accurately measuring the temperature of cold water, with an accurate value of ± 0.5 ℃;
The controller intuitively displays the operation and fault conditions of the compressor, water pump, and refrigeration system accurately;
◆ Easy to operate, just press the switch and it will automatically run.
Adopting world-renowned contactors, relays, thermal protectors, expansion valves, pressure controllers, and drying filters to ensure the reliability of the unit.
The impeller adopts excellent hydraulic model design, with excellent dynamic and static balance and stable performance;
The entire pump adopts imported bearings, which have low vibration and noise;
◆ Coaxial direct structure, high efficiency, small size, light weight, easy installation and maintenance;
The air-cooled low-temperature freezer (freezer) adopts mechanical seals to ensure that the axis is not damaged, there is no water leakage, and the service life is long;
◆ There are power protection (phase loss, reverse phase), compressor overload protection, high and low voltage protection, delay protection, antifreeze protection and other protective devices;
The NBA series air-cooled low-temperature chiller (freezer) has a wide range of applications, including plastic pipes, electroplating, coating, electronics, fine chemicals, pharmaceuticals, food additives, deep processing of corn (starch), cultivation of shiitake mushrooms, grain and oil production, solar photovoltaic industry (polycrystalline furnace, monocrystalline furnace, polycrystalline silicon, monocrystalline silicon, slicer, slicer), air separation, ice skating rink, automotive environmental testing cabin, engine intake system/whole room air conditioning, refrigeration, cold storage, chemical and pharmaceutical intermediates, non-ferrous metals, metallurgy, food processing and preservation industries.
