BVB produces a complete range of filters and accumulators in copper or aluminium , using automatic, precise and highly productive equipment, which allows an optimal balance between quality and cost.
Filters and accumulators can be supplied in a complete range of two or three-way diameters with an ample choice of entry and exit holes.
The quantity and type of molecular sieves are indicated by the client according to his needs (circuit capacity and refrigerating unit).

In the same way the client decides the volume dimensions of the accumulator which is then produced according to his specifications. On request, filters and accumulators can be supplied with service tubes, loading valve or other accessories.

Testing:
- Physical and mechanical characteristics of the copper and aluminium
- Salt spray resistance of the internal components
- Optical and mechanical verification of the filter net
Testing of molecular sieve:
- Density
- Granulometric distribution
- Mechanical resistance (crush-test)
- Maximum absorption capacity (in controlled atmosphere)
- Residual absorption capacity (L.O.I.)
- Losses due to dry and humid attrition (paint shaker attrition)
- Dustiness
