An exchanger is a device that facilitates the transfer of heat between two fluids. The distinguishing feature of an exchanger is that it performs this heat transfer without allowing the fluids, which can be in liquid or gas state, to mix with each other. Usually, the plates or other heat transfer surfaces used inside the exchangers separate the fluids from each other and enable the transfer of heat from one fluid to the other. This heat exchange can be for heating, cooling, or can be bidirectional, occurring simultaneously in both directions.

Brazed heat exchangers are produced by soldering metal plates at high temperatures and provide efficient heat transfer between two different fluids. They are commonly used in areas such as HVAC, refrigeration, and energy production. Their compact structure allows for minimal space usage and offers high efficiency. They are resistant to high pressure and temperature, require low maintenance, but internal cleaning or fluid replacement is difficult, making them ideal for long-term use.

Shell&tube heat exchanger is a device that facilitates heat transfer between fluids at two different temperatures. Fundamentally, it consists of a series of tubes and a shell that surrounds these tubes. One fluid flows inside the tubes, while the other flows through the space created by the shell. This structure allows for the exchange of heat between the fluids without direct contact. Tube heat exchangers are widely used due to their resistance to high pressure and temperature conditions. They find applications in various industries such as chemical, petrochemical, energy production, and maritime. Besides providing efficient heat transfer, they also offer ease of cleaning and maintenance. Their different designs vary to meet specialized application requirements.

A water heater tank is a device used for heating and storing water. It is typically designed to meet the hot water needs in homes, workplaces, and industrial facilities. The working principle is based on heating the water inside with the help of a heat source and storing it for use when needed. Water heater tanks vary according to their capacities and heating systems. Some water heater tanks heat the water directly, while others do so indirectly through a heat exchanger. Energy efficiency, ease of use, and longevity are important factors to consider when choosing a water heater tank.

Centrifugal blowers are mechanical devices used to transport air or gases at high pressure. The basic operating principle involves a rotating fan drawing in air or gas through centrifugal force and then expelling it at high speed. These devices are used in a variety of applications, including ventilation, dust collection, cooling systems, and the transportation of gases in various industrial processes. The design of centrifugal blowers generally includes a fan driven by a motor, a casing in which the fan is mounted, and the intake and discharge points for air or gas. Offering high efficiency and durability, these devices are manufactured in various sizes and capacities to meet different volume and pressure requirements. Centrifugal blowers are preferred for their quiet operation and low maintenance needs.
