The filter drier is the goalkeeper of a refrigeration system. It intercepts moisture, contaminants and acid in the refrigerant line before they reach precision parts such as the compressor. Kilterra KLD/KLE liquid-line filter driers combine high-efficiency molecular sieve with activated alumina for one-step drying and filtration, widely used in commercial air conditioning, chillers and ice makers.
Application Scenarios
- Commercial air conditioning and chillers
- Cold storage and cold chain equipment
- Ice makers and soft-serve machines
- Heat pump heating and hot water systems
- Industrial refrigeration and cold rooms
- Automotive and transport refrigeration
Selection Differences by Scenario
- Match the port size and shell to system capacity and line diameter
- Choose the desiccant formula for your refrigerant (R22/R410A/R32/R290 differ)
- Pick filtration grade by system cleanliness requirements (40-60 mesh is common)
- Select copper or stainless steel shell for corrosive environments; pressure rating must cover peak values
- Choose bidirectional/unidirectional and replaceable-core/non-replaceable by maintenance habits
Product Advantages
Kilterra filter drier shells are formed from drawn copper tube or steel tube in one piece, filled with imported or self-produced molecular sieve with strictly verified charge weight. Brazing uses nitrogen shielding to prevent inner-wall oxidation; every unit passes pressure, leak and dryness sampling tests under the ISO9001 system.
For 37 years Kilterra has focused on one thing: build refrigeration components right, deliver them on time. Filter Drier supports OEM/ODM customization - factory visits, sample testing and volume partnerships are welcome.
