The bi-directional heat pump filter drier is a type of HVAC receiver dryer that can be used in both heating and cooling circulation systems to protect the refrigerant from being contaminated. This streamlined and efficient design keeps contaminants amassed in one direction from flowing in the other direction. Compared with other filter driers on the market, it has two less check valves for a simpler piping system and lower cost.

This copper spun filter drier is used to get rid of contaminants such as moisture, acid, copper oxides, metal chips, and wax compounds within the refrigerating equipment. Made of quality copper which undergoes advanced hot extrusion processes, this receiver drier can be used in refrigerators that use R12, R134A or a capillary tube flow restrictor and other fully hermetic refrigerating systems.

We have developed several types of this reliable HAVC receiver drier for use with refrigerants R22, R134A, R600 and R410A.

The liquid line filter drier is designed for working conditions where the condensing temperature is high and a powerful drying system is needed. This liquid line receiver drier consists of 80% 3A zeolites and 20% active aluminum. It can be used in CFC and HCFC refrigerants such as R22 and R502, which use oil and alkylbenzene at the same time. We offer two different models of a liquid line filter drier-the LEK series solid core liquid line filter drier and the LDK series model core liquid line filter drier.

The core of a filter drier determines the performance of the entire filter direr. We have designed our filter drier core to be easily replaceable every four to eight weeks so that the filter will continue to work effectively. The quality cores made by our company could be applied to all types of filters or Britas provided by Nuandao.com.

Our suction line filter drier is an efficiently designed receiver drier that uses a high quality filter core and provides a larger filtering area. In addition, it is easy and quick to install.

This HVAC filter drier is also equipped with a diffuser that protects refrigerants from abrasions. Its quality, efficient and reliable performance makes it an ideal A/C receiver dehydrator for protecting the compressor of refrigerating systems.

Filter driers have two essential functions: 1) to adsorb system contaminants, such as water, which can create acids, and 2) to provide physical filtration. We provide several types of filter driers to work with the refrigerant and configuration of your refrigerating equipment.

The main models of driers we provide are two-way liquid tube filter driers, copper drying filters, and liquid tube filter driers. All of our filter driers are designed to be reliable, durable, and long lasting, suited for a number different types of equipment.
