What Refrigerant Is Compatible With R12?

What Refrigerant Is Compatible With R12? There are three replacement refrigerant options for R12 systems: R134a, R401a What happens if you mix R134a and R12? R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater

How Do I Keep My Cooling Tower From Freezing?

How Do I Keep My Cooling Tower From Freezing? Use VFDs When Operating Cooling Towers In Sustained Freezing Conditions. While fan cycling or two-speed motors can be employed, variable-frequency drives (VFDs) eliminate cell-to-cell temperature gradients and are preferred when operating cooling towers in sustained freezing conditions. Do cooling towers release contaminants? Cooling towers are often

Can You Use R134a In Place Of R410a?

Can You Use R134a In Place Of R410a? While R134a and R410a are both environmentally conscious hydrochlorofluorocarbon refrigerants, the two are otherwise dissimilar. R134a is a pure refrigerant that is sometimes used in blends, while R410a is itself a blend. … At room temperature R410a has a pressure of nearly 200 psi, while R134a is

What Replaces R12 Refrigerant?

What Replaces R12 Refrigerant? There are three replacement refrigerant options for R12 systems: R134a, R401a How do you convert R12 to R134a? Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. … Open the engine compartment of your vehicle. … Push the high side retrofit R134a fitting
