caleffi automatic air vent

Italian caleffi automatic air vents are primarily used for the separation of impurities and air in heating and cooling systems, preventing the following issues: sediment and scale buildup, loss of heat exchange efficiency, high noise levels, equipment damage, and line blockages.caleffi automatic air vents perform the function of eliminating air accumulated within heating and cooling system loops without any manual intervention.This prevents negative phenomena that may affect the service life and performance of the heating system, such as: - corrosion caused by oxygen;- localized air pockets in radiators;- cavitation in circulation pumps.

caleffi automatic air vent features:

• The automatic vent is designed to remove air accumulated in heating and air conditioning systems without the need for manual intervention.

• Thanks to the automatic shut-off valve, water flow is closed when the valve is removed, simplifying maintenance operations and facilitating inspection of the venting device.

• They prevent harmful phenomena that may affect the service life and performance of heating/cooling systems.

• They are installed in vertical positions on air separators, hydraulic separators, manifolds, and risers, typically in parts of the system where air pockets are expected to concentrate.

• All MINICAL and VALCAL series can be equipped with hygroscopic caps.

• The ROBOCAL series is equipped with anti-rotation and anti-vibration system floats.

caleffi automatic air vents 501 MAXCAL series (for heating, air conditioning, and refrigeration systems):

501 MAXCAL series automatic air vents for heating, air conditioning, and refrigeration systems, size 3/4" x 3/8, model 501500

Function -Automatic air vents are designed to remove accumulated air from heating, air conditioning, and refrigeration systems without requiring manual intervention.This prevents harmful phenomena that may jeopardize the service life and performance of heating systems, including:

- Corrosion caused by oxygen;

- Air pockets trapped in heat emitters;

- Cavitation in circulation pumps;

- Noise generated by air passing through pipes.

These high-capacity air vents are ideal for large piping systems and can also be installed on horizontal sections.

caleffi automatic air vents 551 DISCALAIR high-performance series:

551 DISCALAIR series high-performance automatic air vents, size 1/2" F, model 551004

Function -DISCALAIR devices are capable of releasing large volumes of air formed in the hydraulic circuits of heating and air conditioning systems, even at relatively high pressure values.

This venting capability is due to the special geometry of the ventilation mechanism, which is identical to the geometry of the DISCAL 551 series deaerators.

This prevents negative phenomena that may affect the service life and performance of heating systems, such as:

- Corrosion processes caused by oxygen;

- Air pockets in heating elements;

- Cavitation in circulation pumps.
