Ndl Industries NCH-304S Liquid Line Filter Drier 1/2 Inch

Product Description

The NDL INDUSTRIES NCH-304S is a liquid line filter drier designed for refrigerant systems in residential and light commercial HVAC applications. Liquid line driers serve a critical function in the refrigeration circuit: they remove moisture, acid, and particulate contamination from the refrigerant stream before it reaches the metering device. Moisture in a refrigerant circuit causes acid formation and can freeze at the expansion valve, leading to system failure. The NCH-304S is rated for 1/2 inch line connections and offers a 30 cubic inch desiccant capacity, making it suited for mid-size refrigerant circuit applications.

This drier installs on the liquid line between the condenser outlet and the metering device, such as a TXV or fixed orifice. It is appropriate for residential split systems, light commercial package units, and refrigeration equipment where a 1/2 inch liquid line connection is present. HVAC technicians typically install this component during a system changeout, compressor replacement, or any time the refrigerant circuit has been open to atmosphere and contamination risk is present.

Key Features

• 1/2 inch connection size fits standard residential and light commercial liquid line configurations
• 30 cubic inch desiccant capacity for effective moisture and acid removal
• Designed for installation on the liquid line ahead of the metering device
• Helps protect compressor and TXV from moisture, acid, and particulate damage
• Compact form factor for straightforward inline installation

Compatibility

Designed as an OEM-style replacement or new-installation liquid line filter drier for refrigerant systems using 1/2 inch liquid line connections. No specific model compatibility data was provided in the product input.

Installation Notes

Liquid line driers are installed by licensed HVAC technicians in accordance with applicable mechanical codes and refrigerant handling regulations. Recover all system refrigerant before opening the liquid line. Install the drier with attention to the directional flow arrow marked on the drier body, ensuring refrigerant flows in the correct direction. After brazing or flare connection, pressure-test the circuit, pull a deep vacuum, and recharge with the specified refrigerant type and weight before returning the system to operation.
