Chiller is derived from the Latin word Chill, meaning to cool. Various cycles are used to create refrigeration, the most important of which are the compression refrigeration cycle, the absorption refrigeration cycle, and the thermoelectric refrigeration cycle.

Any system where temperature and water are the main elements for its operation inevitably requires the invention of Abrizan Company, called Industrial Mitreh, because wherever there is temperature and water, the formation of sediment is inevitable, unless a substance is used that suspends these sediments. This is the main function of an excellent anti-sediment solution.

Cold Mitreh, a water-soluble solution with a high dissolution rate, is introduced as a powerful scale remover and an innovative product of Abrizan Company. Cold Mitreh was developed in response to the industry's need for an alternative solution to descalers. Descalers are scale removers based on hydrochloric acid and are highly dangerous, toxic, and corrosive.

Condenser: A unit for controlling temperature in refrigerators, air conditioning systems, and chillers. Its main function is as a heat exchanger in which it converts a substance (refrigerant) from a gas state to a liquid state, from where the latent heat is dissipated by the substance and transferred to the condenser coolant.

Refrigeration is the process of absorbing heat from one fluid and releasing it to another. The fluid can be air, water, or any other gas or liquid. In all refrigeration systems, keeping cool involves absorbing heat from a lower-temperature material and releasing it to a higher-temperature environment.

There are various types of heat exchangers in the industry, examples of which include: double-tube, plate, spiral tube and shell-and-tube heat exchangers, each of which has its own working method. Also, each heat exchanger has its own advantages and disadvantages.
