A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are …

A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum …

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Apart from the rotary evaporator, a vacuum source should be connected to reduce the pressure within the evaporation system, allowing samples to boil at a lower temperature. The vacuum pump is what lowers the boiling point of the product and allows operators to distill solvents using temperatures that go all the way down to room temperature or ...

In an effort to reduce confusion over the color codes of all refrigerant containers, the AHRI has announced that all refrigerant will be using the same color code which is light grey/green based on the RAL 7044 Color Code by the year 2020. Hence, the identification by then will be by product markings and labels instead of by color codes as practiced now.

Uses. One example of an evaporator is a radiator coil used in a closed, compressor-driven circulation of a liquid coolant. This is called an air-conditioning system (A/C) or refrigeration system. It allows a compressed cooling chemical, such as R-22 (Freon) or R-410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the …
