  Among the many pieces of equipment in industrial settings,   dual-mode screw inverter chillers   shine like unique gems, offering exceptional value. For businesses, understanding their special features not only maximizes their efficiency but also brings unexpected benefits in cost control and productivity improvement. Whether in the production workshops of large factories or the server rooms of data centers, dual-mode screw inverter chillers play a vital role. Today, let’s explore what makes them so special. 1. Dual-Mode Operation One of the standout features of dual-mode screw inverter chillers is their ability to operate in two distinct modes: cooling and ice-making. They can seamlessly switch between these modes based on actual needs. In cooling mode, they provide a stable low-temperature environment for production equipment and office spaces, effectively reducing temperatures and ensuring smooth operations while preventing overheating-related failures or reduced lif...

  In the chemical industry,  heat exchangers  are critical equipment for achieving material heat exchange and improving energy efficiency. United Factory, a professional heat exchanger manufacturer, has customized a stainless steel spray heat exchanger tailored to the specific n eeds of chemical plants, meeting the high-performance requirements of heat exchange equipment in chemical production. Material selection is crucial. United Factory uses high-quality 316L stainless steel as the main material for the  spray heat exchanger . This material not only offers excellent corrosion resistance, capable of withstanding the acidic and alkaline environments common in chemical production, but also ensures stable operation under complex working conditions due to its high thermal conductivity and excellent processing properties. The design structure reflects innovation and practicality. The spray heat exchanger improves heat exchange efficiency by uniformly spraying the coolin...

  Industrial chillers  include air-cooled chillers, water-cooled chillers, and  screw chillers , which are widely used in the plastic industry, pharmaceutical industry, food processing industry, chicken hatching bases, etc. However, many customers do not know how to use the industrial chiller after purchasing it, and do not know whether the machine is working properly. Let's talk about the main signs of normal operation of the chiller. 1. Condenser: Water-cooled chiller cooling water system: The cooling water should be sufficient, the water pressure should reach more than 0.15MPa, and the temperature difference between the inlet and outlet water should not be too large, otherwise it indicates insufficient water flow. 2. Compressor: When the compressor is running, the optimal superheat is 4~8 degrees, the maximum suction superheat does not exceed 15℃, and the condensation phenomenon is limited to the compressor return air pipe, and there should be no frost in other parts. ...

  In the operation of hotels, energy costs are a significant factor that cannot be overlooked. The advent of   heat recovery chillers   offers an efficient and energy-saving solution for hotels. ​ A heat recovery chiller, in simple terms, not only performs cooling tasks but also effectively recovers heat. For hotels, this is a highly practical feature. Traditional chillers only accomplish cooling, wasting the heat generated. However, heat recovery chillers are different; they can convert the otherwise wasted heat into usable hot water. In principle, during the cooling cycle of a chiller, the refrigerant releases heat. Heat recovery chillers use special devices to collect this heat, and through a series of heat exchange processes, they can produce hot water. This hot water can be used in various scenarios within the hotel. For example, it can supply water for guest rooms' washing and brushing, provide hot water for the hotel's restaurant kitchen, and even be used for heati...
