A larger size filter- drier is required than if it had been placed in the liquid line. The refrigerant velocity in the suction line is about six times the velocity in the liquid line. Use of Suction Line Filter- Drier s for HVAC Clean-up After Burnout.
The Suction Line Filter-Drier method of cleaning up a system after a hermetic motor burnout is favored by service technicians and recommended by manufacturers throughout the HVAC and refrigeration industry. This method gives the most practical and positive protection.
White Rodgers, Parker Hannifin and Emerson Flow Controls suction line driers are designed to clean up your refrigerant system after a compressor burnout has occurred. They remove solid contaminants and harmful acids that are created during a motor burnout. The solid-core clean-up dryer was developed for use in a system suction line. The compact design incorporates a large outside diameter shell, which in a shorter lay-in length, and a larger core, which provides a greater filtration area for maximum operating efficiency.
If you do choose to LEAVE a suction drier in a system there are a few things to consider. In this case, the higher velocity in the suction line will cause the loose fiber glass structure to disintegrate. The core can be used effectively in the suction line drier.
The rigid cores can be tailored to remove the solid particles that result from compressor breakdown, sludge, and resins. The obvious benefit of a suction line filter drier is the added protection given the system if a burnout should occur. The filter will effectively prevent contamination resulting from the failure from traveling back through the suction line into the other parts of the system. Suction driers point towards the compressor and away from the evaporator. Dessicants are more selective as a Cool liquid.
I see nothing wrong with leaving a suction drier in place. A hot molecule of water looks like this. Leave the suction dryer in place. Stock up on suction line driers in the parts and supplies department of LennoxPros. The discharge line is between the compressor and the condenser.
A liquid line drier goe in the liquid line NOT in the discharge line. The liquid line is between the condenser and the metering device. Flow nitrogen while brazing and pull a proper vacuum. Liquid… what is the difference between. The PARKER steel shell suction line filter dryer is designed for system cleanup.
Compact design incorporates large outside diameter shell for shorter lay-in length, and a larger core for a greater filtration area for maximum operating efficiency.
Filter driers are devices used in a HVAC system that are a combination of filter and dryer (or drier ). A filter is used to remove any particle such as dirt, metal or chips from entering the refrigerant flow control. Installation Tips: Suction Line Filter-Drier. These suction line filter-driers include protection from moisture and organic or inorganic acids, resulting from burnouts, or chemical changes in the system refrigerant or oil. They’re especially suited for system cleanup after a burnout, or when major work has been performed on the system. The subject here is suction line filter driers.
Suction line driers will typically have pressure taps on them. If you have either gas-in-and-gas-out or liquid-in-and-liquid-out, then you get no temperature drop. The SFD is a standard suction line filter- drier for use after a burnout or when major work has been performed. Start the compressor and put the system in operation.
Record the pressure drop across the suction line filter-drier on the enclosed label and apply to the side of the drier shell. Replace the suction line filter-drier if the pressure drop becomes excessive. Fastenal uses Cookies to Improve Website User Experience.

Alternatively, 96-TS filter driers can be installed as a suction line filter drier in remote systems with long refrigerant lines. The filter drier will collect and hold any dirt that is in the evaporator or suction line at start-up.
I regenerate the driers every week. Wrap all filter driers and service valves with wet cloth when brazing. Please note: All items are not yet available for use with our Filtered search. If an item is not available via the filters, try searching for the part number or description using the search box at the top of the page.
Suction Dryer SDS FTNON has developed a suction dryer which delivers the end products not only dryer but also in optimum condition. Shop for Suction Line Filter Driers at Ferguson. Assuming there is a byflow liquid line filter drier , how does one install suction line filter drier ? I would assume by putting two side by side with a check valve and piping so it would only flow with the direction of the vapor. A wide variety of suction dryers options are available to you, such as plastic, metal, and acrylic. For use with CFC, HCFC and HFC.
GemTech Suction Line Filter Drier Please Note! The actual brand name on product received may vary from the description but will always be manufactured to the same strict standard of quality. On a medium temperature system, what is the maximum pressure drop across its permanent suction filter- drier before it must be replaced? If a suction filter is installed temporarily to clean up acid after a burn-out, what is the maximum length of time before it must be removed?
POE oils absorb moisture rapidly. Do not expose oil to the atmosphere.
