Evaporators
Stable boiling and consistent temperatures
An evaporator is an essential component of any refrigeration system. Within the evaporator, a liquid refrigerant is circulated through a reduced-pressure environment that causes it to boil at a lower temperature than it would at atmospheric pressure. As the refrigerant boils and becomes gaseous, it absorbs heat from a secondary fluid.
Efficient heat transfer
Positioned as evaporators, SWEP brazed plate heat exchangers deliver a stable boiling process that enables more efficient heat transfer between the refrigerant and the secondary fluid. Because of their innovative plate design, SWEP BPHEs also facilitate heat transfer between fluids with a low temperature difference.
Lower energy consumption
A higher evaporating temperature also reduces the amount of work the compressor has to perform to elevate the pressure of the refrigerant. This decreases the electricity consumption of the system, resulting in higher COP.
Higher evaporation temperature
The majority of the heat transfer area in the evaporator is dedicated to evaporation. Superheating occupies approximately 5% of the surface area, while the gas heating process uses 10-25% of the total heat transfer surface.
With lower-temperature superheat (a), more active surface is available to evaporate the refrigerant. The result is a higher evaporation temperature and COP.
In contrast, if the evaporator is unstable, higher-temperature superheat is required (c), which results in a lower evaporation temperature and COP.
Efficient operation at full or partial load
SWEP evaporators support stable, efficient operation, whether operating at full or partial load. SWEP’s distribution systems ensure a homogenous mixture of the fluid, resulting in an evenly distributed flow over the plate package.
SWEP products that work as evaporators
SWEP offers a wide range of highly efficient brazed plate heat exchangers that can be optimized for use as evaporators.

CLEANING IN PLACE
The simple solution to scaling and fouling
The highly turbulent flows inside a brazed plate heat exchanger are usually enough to keep it clean. However, in applications with a high risk of fouling or scaling due to high temperatures, hard water, or high pH levels, cleaning in place (CIP), may be necessary to maintain efficiency.
