DQB series bi-flow filter driers protect refrigerant from impurity pollution in refrigeration and heating cycles, which ensures effectively the impurities collected in one direction return back at opposite direction. This design successfully decreases two external check valves and two conventional filter dryers,
FEATURES
• With the functions of drying and filtration, irreversible-flow valves installed at both ends, impurity can be filtered with bi-flow operation, variable flow and filtration can be realized in heat pumps and reversible cycles, built-in check valves achieve precise bi-flow control.
• High efficient in moisture absorption, filtering impurity, acid, paint remains and mud removal
• Unlimited installation position
• Corrosion resistant painting can survive salt spray test of 500 Hours
• Connection type: ODF solder
OPERATION CONDITIONS
• Applicable Refrigerants:R410A,R32, R134a, R404A, R507, R407C and R22 (For R290. please confirm before placing orders.)
• Maximum Working Pressure: 4.6MPa
• Medium Temperature：-40℃ ~ 80℃；
• Ambient Temperature：-40℃ ~55℃；
• Relative Humidity: below 95%
