R 22 superheat subcooling calculator charging chart c
For sale is one new slide type calculator used for calculating R 22 superheat and subcooling. This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is used for calculating superheat for a NON-TXV system and the other side is used to calculate subcooling on a TXV system. On the bottom of one side is also a calculator for measuring proper airflow over evaporator coils. The photo shows both sides of the tool. This tool is made of thick durable cardboard with corner rivets and is aproximately 7.75 inches long by 3.75 inches wide. If you have any questions, feel free to ask and I will answer them to the best of my ability.
