Evaporator Types. The two general types of evaporators used in today's refrigeration systems are flooded evaporators and dry, or direct expansion (DX), evaporators. Flooded Evaporators. As the name implies, a flooded evaporator is always filled with liquid refrigerant. Depending on the refrigeration system, certain flooded evaporators can be ...
TYPES OF EVAPORATORS. Two main categories of evaporators used in industrial refrigeration practices air coil and liquid coolers. A typical air coil shown in Fig. 6.2 and several types of liquid coolers are shown in Fig. 6.3. In the air coil, refrigerant passes through the pipes and air passes outside the tube.
Types of evaporators. Evaporators are distinguished into different types based on the way they achieve the heat transfer. For instance, the working of forced circulation evaporators relies on pumps to circulate the feed whereas falling film evaporator design calculations rely on gravity.

The rotary evaporator is mainly used for concentration, crystallisation, drying, separation and solvent recovery. Horizontal tube evaporators. The horizontal tube evaporator is the oldest type of chemical evaporator, although other improved types are now more commonly used. The main advantage of horizontal tube evaporators is the relatively ...
Over the years, process engineers have developed different types of evaporators suitable for a plethora of applications. Choosing the right evaporator mainly relies on the characteristics of the products and the desired results. Any variant of an evaporator is made of components including, heat exchangers, manifolds, condenser, controls, and pumps.
available today. In almost all evaporators the heating medium is steam, which heats a product on the other side of a heat transfer surface. The following list contains the descriptions of the most common types of evaporators. 1. Falling Film Evaporators 2. Rising Film Evaporators 3. Forced Circulation Evaporators 4. Plate Evaporators 5.
TYPES OF EVAPORATOR Created Aug. 29, 2019 by user GUNASUNDARI V. TYPES OF EVAPORATOR. Natural/forced circulation evaporator. Natural circulation evaporators are based on the natural circulation of the product caused by the density differences that arise from heating. In an evaporator using tubing, after the water begins to boil, bubbles will rise and cause circulation, …
Evaporators are used in various processes including pharmaceuticals, foods and beverages, pulp and paper, chemicals, polymers and resins, inorganic salts, acids, bases, and many other things. In this article, we will discuss the various types of evaporators, its advantages and disadvantages, and its applications.
Caloris made its name in evaporation and there are many different types of evaporators to choose from. Here is a rundown of the different types of evaporators that Caloris offers: MVR Evaporators. MVR stands for Mechanical Vapor Recompression. MVR turbofans generate heating vapors by compression of the water vapors evaporated from the product.
Tube or Shell Type Evaporators. In large refrigeration and central air conditioning systems, evaporators of the shell and tube types are utilized. Chillers are the usual name for the evaporators in these systems. A huge number of tubes are …
Evaporator types can be divided into three main groups according to the characteristics of the application: – The evaporators used to cool the gaseous substance (usually air) – Substances in the case of liquid refrigerant evaporators (water, brine, antifreeze, methylene glycol, chemical fluid, etc.) – Solids evaporators cooling (ice, ice ...
Types, Function & Applications. Evaporator can be defined as, "a heat transfer surface, in which, a volatile liquid refrigerant is vapourized by removing heat from the refrigerated space or product". The evaporator is also known as cooler or freezer or chiller. It is connected in the low pressure side of the refrigeration system.
Forced circulation evaporators are used for sodium sulphate, citric acid, urea, sodium chloride, caustic potash, ammonium sulphate and magnesium chloride. 3. Climbing and Falling-Film Plate Evaporator: ( Types of Evaporators ) These evaporators have generally larger surface area. The plates are generally supported with the help of frame and are ...
People many types get confused with condensers and evaporators. Condensers are the equipment that rejects heat to sink to cool the liquid while the evaporator absorbs heat from things to be cooled. Evaporation is a surface phenomenon and hence in an evaporator, it is always tried to achieve maximum surface area to achieve maximum heat transfer.
The most common type of forced circulation evaporator is the submerged-tube type. In these evaporators the heating element is below the liquid level. This ensures that no boiling occurs in the tubes. The heating elements may be oriented either vertically …

Refrigeration evaporators design. Modern air-cooled evaporators, regardless of type, is the complex device. It consists of: finned tubes, housing, special compartments for evaporation, a fan system, an electric motor system, a thermo-electric cooler, as a rule, when the evaporator is operating with the boiling point of the refrigerant below 0 °C.
Chapter Four – Types of Wastewater Evaporators. The purpose of vaporization is to change a liquid to a vapor. Though vapor and gas may seem interchangeable, vapor is unlike gas because it begins as a liquid and is transformed into a vapor. When a liquid is changed to a vapor below its boiling point, the process is referred to as evaporation.
Evaporators are used in a wide range of processes, including pharmaceuticals, foods and beverages, pulp and paper, chemicals, polymers and resins, inorganic salts, acids, bases, and a variety of other materials. There are many types and variations of evaporators,and the best for a particular application depends on the product characteristics ...
The three most common types of evaporators used in food concentration are long-tube vertical evaporators, forced-circulation evaporators, and plate-type evaporators. Falling-film evaporators are constructed around a vertical bundle of large-diameter long tubes, with a liquid distributor on top and a vapor/liquid separator section below.
