refrigerant gas R507

Description

R**7 is an HFC replacement option for R**2 and R***2 in low and medium-temperature commercial refrigeration systems. It can be used in new and existing systems, and provides very similar performance to R***2 over the entire operating range.
 
 
 
Replaces
 
R**2 and R***2
 
 
 
Applications
 
Low and medium temperature commercial refrigeration equipment., including supermarket -display cases, transport refrigeration and ice machines.
 
Low and medium temperature industrial refrigeration applications.
 
 
 
 
 
R***2D will show a drop in capacity compared to R**2,which usually translates into slighty increased run times in a properly sized system.Some system conponents may need to be changed if excess pressure drop debelops.
The hydrocarbon component in R***2D helps promote oil return in systems containing mineral oil or alkylbenzene.Although HFC refrigerants won\'t mix with these oils,the hydrocarbon addition thins the oil and keeps it moving around the loop.More complicated piping arrangements or large hold-up volumes may still require some oil be changed to POE.
