It is said that necessity is the mother of invention. As energy prices soared in the 1970s, supermarket owners sought ways to reduce their enormous utility bills. Unlike comfort cooling equipment, ...

Myke King breaks down compressor load control and shows how experienced engineers can implement these systems in the DCS without relying on proprietary solutions COMPRESSOR control schemes are often ...

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

This repository contains a comprehensive implementation of a programmable logic controller (PLC) program designed to maintain and control pressure within a compressor receiver system. The logic ...

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, ...

[Editor’s note: This is the second in a three-part series on one of the newest refrigeration technologies: the electric suction line regulator. The first part appeared in the Jan. 12 issue of The NEWS ...

Compressor surge occurs when flow is too low with respect to the change of pressure of the compressor or when ΔP is too high with respect to the flow. A decreasing flow coupled with an increasing ∆P, ...

WHILE some machines can operate in surge for extended periods, others can quickly suffer mechanical problems. And, of course, surge can cause major disruption to the downstream process. While we ...

Abdelhak Dhabi explains how variable speed control of compressors can be deployed to reduce energy consumption and wear, as well as increasing the overall system efficiency of refrigeration ...
