Emerson Alco 043333 Drier

The Emerson Alco 043333 (Model BFK 163S) is a high-performance bi-directional liquid line filter drier designed specifically for heat pump applications and reverse cycle systems. Engineered for refrigerant contaminant removal, this unit features a 16 cubic inch desiccant volume and 3/8" ODF sweat connections, making it a reliable direct cross for 62A52 components. With a 40-micron filtration rating and a maximum working pressure of 680 PSI, this drier ensures HP HVAC system protection by effectively capturing moisture, acid, and solid debris in both flow directions without requiring external check valves. The solid core desiccant blend is optimized for modern HFC refrigerants and POE oils, maintaining system chemistry integrity and preventing capillary tube or expansion valve blockage in demanding field conditions.

• Dual-flow internal check valves eliminate the need for external piping, simplifying installation in heat pump circuits.
• High-capacity desiccant core ensures maximum moisture and acid neutralization in 3/8" liquid lines.
• Shock-resistant steel shell construction rated for high-pressure 680 PSI environments.
• 40-micron solid core filtration protects sensitive compressor components and TXVs from debris.
• ODF sweat connections provide leak-proof, brazed integration for long-term reliability.

Is the Alco BFK163S compatible with R-410A systems?
Yes, this unit is rated for 680 PSI, making it suitable for high-pressure R-410A heat pump systems used in residential and light commercial applications.

Can this filter drier be installed in any orientation?
While bi-directional, it is best practice to install the unit vertically with a downward flow if possible, though it functions effectively in horizontal runs provided suction traps are not compromised.

Does this replace the 62A52 model?
Yes, the 043333 is the direct technical cross-reference for the 62A52, sharing identical connection sizes and internal capacity.
