Emerson Alco 059908 Drier

The Emerson Alco 059908, also designated as the TBF163S bi-directional liquid line filter drier, is a 16-cubic-inch capacity desiccant core engineered specifically for heat pump system protection. Featuring 3/8" ODF sweat connections, this unit optimizes refrigerant flow in both heating and cooling cycles without the need for external check valves. With a 500 PSI maximum working pressure, it is fully compatible with high-pressure refrigerants like R-410A and R-22. The solid core desiccant blend provides high-moisture removal and acid filtration, preventing compressor failure and thermal expansion valve (TXV) plugging. Its compact steel shell construction ensures high burst pressure integrity, making it a reliable drop-in replacement for the 96-TBF163S. This drier is essential for maintaining system dehydration and preventing the formation of harmful sludge and organic acids in the high-side liquid line.

• Internal Check Valve Logic: Eliminates the need for external piping, simplifying retrofits in bi-directional heat pump applications.
• High-Moisture Capacity: The 16 cubic inch desiccant core effectively sequesters moisture and prevents acid formation under high thermal loads.
• Standardized Fit: The 3/8" ODF copper fittings ensure a standard brazed connection for fast field installation.
• Pressure Rating: Rated for a 500 PSI design pressure, providing a necessary safety margin for modern high-pressure HVACR systems.

Common HVACR Technical Questions

Can the Alco 059908 be used in straight-cool AC systems?
While designed for bi-directional flow in heat pumps, this drier functions effectively in unidirectional systems; however, a dedicated liquid line drier is typically preferred for cost-efficiency in non-reversing applications.

Is this drier compatible with POE and mineral oils?
Yes, the desiccant chemistry in the TBF163S is compatible with both Polyolester (POE) and Mineral Oil systems, making it versatile for R-410A and R-22 charge types.

What is the micron filtration rating?
The internal fiberglass final filter is designed to trap solid contaminants down to 20 microns, protecting sensitive expansion valves and capillary tubes from debris.
