Ensure a permanent refrigerant filtration of refrigeration and air conditionning circuits. Two access valves allow measurements of the filters'pressure drop to check filter saturation. Filtration ensured thanks to a special internal felt core.

Recommended for decontaminating refrigerants during start-up periods or after compressor burn-out, the BDCY, ACY or BACY replaceable core filters stop solid contaminants before the compressor. Their functions - filtration, moisture adsorption, waxes fixation and acid neutralisation - can be adapted to meet the requirements of the refrigeration and A/C systems with different cores made by CARLY.
