Application Notes

Here's how some of our customers used this product.

CO2 Condensing Unit

The Background: Our customer is an engineering firm working on a project that requires recapturing CO2 that is used in an industrial process.

The Problem: The customer is using condensing unit and solenoid valves to reprocess CO2 gas back into liquid for storage. They require an instrument that can control the entirety of this process.

The Solution: We recommended the GE Automation Versamax Micro 20 controller. With custom logic running control, digital inputs to take pulse inputs and digital outputs to open and close the valves, the Versamax Micro 20 is the perfect fit for their application.

Customer is able to efficiently control and monitor their process exactly the way they wanted, as they paired their hardware with Instrumart PLC programming.
