A pH controller consists of a probe to measure the current pH of the substance, chemicals to correct the pH via an injection pump, and a controller that calculates the required injection rate and activates the injection system.
Flameless vents are installed on top of explosion vents and contain multiple layers of high temperature stainless steel mesh to absorb the heat of a deflagration. By cooling the deflagration beneath the fuel’s ignition temperature, combustion is stopped and only pressure escapes the device.
