Typical applications in the nautical field

The air separator COAS631L is intended for use on:

• water circuits of marine air conditioning systems Frigomar;
• centralized systems with chilled water chillers;
• installations where an air separator with 2.7 liters capacity and connections compatible with 20 mm o 25 mm.

When choosing a replacement, the correct match is made by verifying code, commercial reference, space requirements and connection diameters compared to the installed component.

Functional advantages (without unverifiable claims)

Within a hydraulic air conditioning circuit, the presence of air can make the management of flow and operating conditions more complex. A dedicated air separator is designed to support venting and bubble separation, with practical benefits related to system management.

• Support for air venting present in the water circuit.
• More regular circulation of the fluid in the air conditioning circuit.
• Contribution to the correct operation of system components (pumps, chillers, and fan coils), reducing conditions typically associated with the presence of air in the circuit (e.g., cavitation phenomena and efficiency drops).
• Format and connections consistent with installations in the nautical field where defined dimensions and connections from 20 o 25 mm.

Usage and notes for installation/replacement

Recommended checks before purchase

• Code verification: check that the requested spare part is COAS631L (reference CL631L).
• Check clearances: compare height, width and depth with the available space on board.
• Check connections: verify the diameter of the necessary connections (inlet/outlet 20 o 25 mm).
• Orientation: consider the vertical configuration planned for installation in the water circuit.

General operational notes

• During maintenance activities of the water circuit, proper venting management and restoration of operating conditions are important aspects for system stability.
• In case of doubts about compatibility or system configuration, it is advisable to refer to the system documentation or the removed component (code and measurements).
