Revolutionary axial fan concept Noise emission and energy efficiency are key aspects for axial fans used in the evaporators, condensers and heat exchangers in ventilation, refrigeration and air conditioning systems – in addition to the required air flow. To be able to fully exploit the potential available for optimization, the fan has to be considered

Cold Rooms: an Introduction
Refrigeration is important for maintaining a proper, unbroken cold chain. Using dairy as an example, after the cows are milked, their milk is pasteurized and rapidly chilled. Once the milk has been chilled, it must be maintained at that low temperature from the farm to the grocery store, including during bottling and shipping. If the
Repair of refrigeration equipment
High-quality commercial and industrial refrigeration equipment purchased from reliable suppliers, initially has a long service life. However, even these devices are sometimes broken. Naturally, the question arises - who entrust the repair of refrigeration equipment. The problem is usually complicated by the fact that the operation of refrigerating and freezing equipment necessary to restore as
Types and properties of coolants
Coolants - a substance through which the heat from the cooled objects transferred to the refrigerant. Basic requirements for the coolants: low freezing temperature. It must be below the evaporation temperature of the coolants in the evaporator at 5-8 degrees; a large heat capacity and thermal conductivity; low viscosity and density; chemical neutrality to construction
Refrigeration compressors
In this article you will know about the main types of compressors for refrigeration: on a kinetics − piston, screw, scroll, centrifugal; on a design − hermetic, semi-hermetic and open. Looking for refrigeration compressor on our global directory. Refrigeration compressors Refrigeration compressors provide a refrigerant circulation in the system and, unlike gas compressors, are not used
Classification of refrigeration systems
Cold supply can be carried out both from the refrigeration station and the refrigeration plants. The refrigeration scheme is a circuit of interaction of cooling stations or plants with users of refrigeration. When developing refrigeration schemes, the design engineers seek to create optimal conditions of the system operation. Thus, this is, first of all, the
