ultra-low temperature chillers

Heat accumulation in industrial manufacturing not only impairs product quality but also severely constrains production efficiency. As the core equipment for removing thermal loads, refrigeration chillers precisely absorb heat from process circulating water using the principle of phase-change heat absorption by liquid refrigerants. In large-scale manufacturing bases and centralized cooling systems, large-scale chillers serve as essential infrastructure to ensure the continuous operation of entire production lines, with screw chillers commonly powering their core. The unique twin-rotor stepless regulation structure of screw compressors grants these units exceptional part-load efficiency and extremely low failure rates, making them the preferred solution for high-capacity, continuous cooling....

  The fundamental operation of an industrial chiller relies on fluid media circulation to achieve heat transfer. Varying process media, flow rates, and pH levels demand specifically matched chiller units. Improper fluid compatibility easily leads to piping scaling, heat exchanger corrosion, and heat transfer efficiency degradation. Below is an overview of fluid selection logic tailored to different chiller types.   Large-scale chillers rely on closed-loop fluid piping networks to achieve centralized heat exchange across manufacturing facilities. The market is primarily dominated by two major categories: screw chillers and air-cooled chillers, which differ significantly in their fluid circulation structures. Screw chillers utilize two distinct fluid loops—a cooling water loo...

When discussing the overall performance of a refrigeration system, most people focus on the compressor's power, often overlooking the role of the circulating medium. The fluid's specific heat capacity, viscosity, corrosiveness, and anti-freezing properties directly determine the heat exchanger's heat transfer efficiency and the piping's pressure drop. Ignoring the compatibility of medium characteristics makes it difficult for even the most advanced equipment to achieve ideal cooling performance.   The structural design of the unit varies significantly depending on the fluid medium and temperature requirements. In processes that use specialized secondary coolants for deep-freezing cycles, high-specification ultra-low temperature chillers must be installed. Beyond optimizing the interna...

Indoor ice skating rinks, ice hockey arenas, and various ice sports centers have high requirements for ice quality. The ice surface must remain flat and hard while avoiding surface melting or bubble formation. Beneath the ice rink surface lies a dense network of cooling pipes through which low-temperature secondary refrigerants circulate to continuously remove heat from the ice layer. The core of this process is an efficient and stable industrial refrigeration system.   To prevent the secondary refrigerant from freezing at sub-zero temperatures and to ensure smooth fluid flow, ice rinks commonly use glycol low-temperature chiller units as their primary cold source. The system cools a glycol-water solution down to between -10°C and -15°C, then pumps it through the pipe network...
