Fan-coil AT9HVZ -SI 6" MR 230V 50–60Hz – code: MA261300415 – Dometic

The Dometic AT9HVZ-SI fan coil (code MA261300415) is a fan coil/air handler intended for air conditioning systems chilled water in the nautical field. The unit is designed for air distribution in indoor environments and for integration into centralized systems with chillers, where the fan coil represents the emission terminal.

This version is identified by the wording 6" (MR) and provides power supply 230 V AC with frequency 50–60 Hz, as reported in the available data. It is a typical solution for interventions of spare parts, replacement or restoration of existing units in Dometic systems.

Features and details of the fan coil

The code MA261300415 uniquely identifies the model AT9HVZ-SI of Dometic. When ordering spare parts, referencing the code is essential to reduce ambiguity and speed up the correct identification of the component.

Identifying data

• Brand / manufacturer: Dometic
• Model: AT9HVZ-SI
• Product code: MA261300415
• Type: Fan Coil / Air Handler for chilled water systems
• Power Supply: 230 V AC

Component function in a chilled water system

In a centralized chilled water air conditioning system, the fan coil acts as the terminal unit. Essentially, it helps to:

• distribute conditioned air in the spaces;
• use chilled or hot water coming from a chiller;
• support cooling and heating of indoor spaces (depending on the system configuration);
• ensure air movement through a fan.

Features of the HV series (standard information)

The model belongs to the HV series by Dometic, equipped with construction elements designed for marine installation and condensate management. Specifically, the following standard features are listed:

• high velocity blower;
• condensate collection tray made of corrosion-resistant composite material;
• anti-vibration mounts to reduce noise and vibrations;
• possibility to orient the fan to adapt to different installation configurations;
• condensate drainage channels designed to promote water flow.

Typical applications (nautical and onboard plant engineering)

The fan coil AT9HVZ-SI is intended for marine air conditioning systems Dometic Chilled Water, where it is paired with a centralized chiller. It is suitable for installations and maintenance in contexts such as:

• pleasure boats;
• yachts;
• centralized marine chilled water air conditioning systems.

Compatibility and correct identification

Compatibility should be primarily verified through the product code MA261300415 and model AT9HVZ-SI. In the presence of existing systems, checking the code on the installed unit or on the onboard technical documentation is the most reliable method to confirm the match of the replacement part.

Operational advantages (conservative approach)

This fan coil offers practical advantages typical of a correctly identified original spare part and a series designed for the marine environment:

• Traceable spare part: the Dometic code allows clear identification during ordering and warehouse management.
• Integration in chilled water systems: designed as a terminal unit in centralized systems with chillers.
• Condensate management: presence of dedicated drip tray and drains (standard features listed).
• Adaptable installation: possibility to orient the fan for different configurations (standard feature listed).
• Vibration reduction: anti-vibration mounts indicated to contain noise and vibrations (standard feature listed).

Usage, notes and purchase indications

This product is a fan coil/air handler for chilled water systems. For correct selection and to avoid incompatibilities, it is advisable to always check:

• spare part code: MA261300415;
• model: AT9HVZ-SI;
• power supply and frequency: 230 V AC, 50–60 Hz;
• reference “6” (MR)" as indicated in the model description.

Installation notes (generic)

Installation and commissioning must be carried out according to the procedures provided by the system and the Dometic chilled water system documentation. In case of replacement, it is good practice to compare the existing unit (label, code, model) with the ordered spare part and verify the correct condensate drain management according to the onboard configuration.

Why always specify the code in the request

In the marine spare parts sector, similar names may refer to different variants. Specifying MA261300415 in the request for quotation or order helps maintain consistency between spare part, documentation, and installed system.
