Self-contained unit “Inverter BLDC” 7,000 BTU/h – code: SCU07VFD-E – Frigomar

The Frigomar self-contained unit “Inverter BLDC” (code SCU07VFD-E) is a compact solution for on-board air conditioning, designed for installations where size, consumption, and ease of installation are determining factors. The adoption of inverter allows a more modulated management of operation compared to traditional ON/OFF systems, with the aim of improving comfort and temperature continuity.

This unit is designed and manufactured in Italy and is compliant with the EMC directive. It is suitable for marine and plant applications where a complete self-contained unit is desired, with dedicated electrical panel and provision for air ducting.

Main features and details

Compact design and simplified installation

The project focuses on a very compact and lightweight design, useful when technical space on board is limited. The unit is declared easy to install and is supplied with electric panel separate (dimensions indicated below), for an orderly management of connections.

Inverter BLDC Technology

Compared to ON/OFF solutions, inverter technology is designed for a more progressive regulation of operation. The provided content indicates an energy efficiency superior of the 50% compared to ON/OFF models and a maximum comfort thanks to silent operation and more stable temperature (depending on installation and usage conditions).

Consumption management and start-up

Among the highlighted points:

• Minimum consumption: input power 150 W in mode ECO (declared data).
• Elimination of startup peak current (declared data: 2 A max).

These features can be useful in onboard systems where the management of electrical loads is an important aspect.

Typical applications (nautical and onboard plant engineering)

The SCU07VFD-E is designed for contexts where a self-contained unit with inverter management is desired, suitable for:

• Cabins and interior spaces with ducted air distribution, thanks to the duct outlet.
• Refit or new installations where compact dimensions and a dedicated electrical panel are needed.
• Systems with seawater circuit (based on declared pressure drops) and with power supply 230 V single-phase.

The correct application depends on the system design, available ventilation, and the configuration of air intakes/supplies.

Operational advantages

More stable comfort

The inverter logic is aimed at maintaining a more constant temperature and reducing the typical variations of ON/OFF systems. The provided data also indicates a quiet operation, a relevant aspect in onboard living environments.

More efficient energy management

A energy efficiency superior by 50% compared to ON/OFF models (declared data) is reported. The presence of the ECO mode with indicated input power can help contain consumption under reduced load conditions.

Start-up without peaks

The elimination of the peak current at startup (declared data: max 2 A) is a practical advantage in systems where starting high loads can create issues or require oversizing.

Quality and compliance

The product is designed and manufactured in Italy and declared compliant with the EMC directive, a useful element for integration into onboard electrical systems.
