What are the two most common types of heat exchangers?

There are two main types of regenerative heat exchangers—static heat exchangers and dynamic heat exchangers.

What are the symptoms of a blocked heat exchanger?

Banging or whistling noises Over time, the water in the heat exchanger can cause limescale to build up. This limescale can cause blockage and inefficiency. When it does, it causes the water to get hotter too. As the water comes to a boil, the build up of bubbles and steam will cause a whistling noise.

When to use a packless refrigerant heat exchanger?

Refrigerant Heat Exchangers Packless Turbo Heat Exchangers are specifically intended for application on refrigeration systems to transfer heat between liquid refrigerant leaving the condenser on the high pressure side of the system and refrigerant vapor leaving the evaporator on the low pressure side of the system. All HXRS are UL listed.

How are heat exchangers used in a refrigeration system?

Packless Turbo Heat Exchangers are specifically intended for application on refrigeration systems to transfer heat between liquid refrigerant leaving the condenser on the high pressure side of the system and refrigerant vapor leaving the evaporator on the low pressure side of the system.

How are the tubes of a heat exchanger secured?

There are two end plates which are sealed on both the sides of the shell and a provision is made at one end to cater for the expansion. The cooling liquid passes through the tubes which are sealed on either end into the tube plate. The tubes are secured in the tube plate by bell mouthing and expansion.

What kind of heat exchanger is used for scrapping?

The scrapping is done by a blade unit operated by a motor-driven shaft with timer moving inside the frame. This heat exchanger is normally used for heat transfer of highly viscous fluid by increasing the turbulence of the fluid.
