Service technicians will often experience frost on a suction line or on the compressor in some refrigeration applications. Thinking that liquid refrigerant must be present because there is frost is a ...

The purpose of a compressor in a chiller is to lower the pressure and temperature of liquid refrigerant to a point below the temperature of the brine in order to allow heat to flow from the brine to ...

The trunnion ball valve design maintains a reliable seal under high differential pressure without excessive torque, ensuring ...

Proper air filtration is critical to the overall performance and reliability of gas turbines. Fuel costs approach 80 percent of the life cycle cost of electricity. Small gains in efficiency can mean ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...
