Condensers and Evaporators

All refrigeration and air conditioning systems contain at least two heat exchangers – the evaporator and the condenser. At Mahan’s Thermal Products, you can find condensers and evaporator in a wide range of sizes and capacities, in accordance with our customers’ needs.

Condensers and evaporators are heat exchangers in which the refrigerant is subjected to a phase change. Basically, the condenser transfers heat from the refrigerant to the outside air, while the evaporators draw heat from the air.

Condensers and evaporators are widely used in HVAC-R processes, ranging from industrial to domestic applications. Their main purpose is to achieve a heat duty at the penalty of pumping power.

Since condensers and evaporators are heat exchangers, there are a lot of similarities in terms of functions and designs between the two of them. However, when referring to the heat transfer process, there are a number of differences.

A condenser is a two-phase flow heat exchanger in which vapor is converted into liquid by a coolant, while an evaporator is also a two-phase heat exchanger, but in which the liquid is converted into vapor by the heat supplied through a heating medium.

When plate heat exchangers are used for condensation and evaporation, they care called plate condensers and plate evaporators; when shell & tubes are used, they are called shell & tube evaporators and condensers.

  • Plate evaporators

Plate evaporators are very similar to plate heat exchangers, but they are equipped with a larger passage for the vapor flow. The product plate and steam plate in this design are connected alternately, so that there is an even distribution on the plate surfaces.

  • Plate condensers

Condensers play an important role in most processing industries, as they are designed for condensing vapor into liquids at low pressures.

Compact and efficient, plate condensers are ideal for a wide range of applications, such as vacuum condenser in evaporation crystallization systems or turbine condenser in small power plants.

  • Optimized performance

Compared to conventional shell & tube condensers and evaporators, plate condensers and evaporators not only require less floor area, but they are more energy efficient, more cost effective and don’t require as much maintenance.

Plate condensers and evaporators are more compact and can be installed in most buildings.

Due to their design, plates can be easily changed if necessary and the evaporation or condensation rate can be increased.

At Mahan’s Thermal Products, you can find condensers and evaporator in a wide range of sizes and capacities, in accordance with our customers’ needs. Our selection includes some of the best products in the industries, such as condensers and evaporators from Alfa Laval.
