Alco filter dryers
ALCO filter driers - our product range
.Our online shop offers a wide range of ALCO hermetic filter driers for liquid refrigerants, which have very high water absorption capacity combined with above-average acid binding.
Which filter drier fits?
What matters is connection type, connection size and volume. All three are often in the type, e.g. DML 083 or 4208/3S.
Connection
What matters is connection type, connection size and volume. All three are often in the type, e.g. DML 083 or 4208/3S.
- Reading the type: in DML 083 or Castel 4208/3, 08 stands for 8 in³ volume and 3 for a 3/8" connection. An S at the end means solder connection.
- For reversible heat pumps and air conditioners, choose a bi-flow drier; after a compressor failure, an anti-acid drier.
- Replace the drier every time the circuit is opened and only open it shortly before brazing it in – it draws moisture from the air.
