Frigomar Mini 30 – Marine Chiller 601NT (32,500 BTU/h)

Compact air conditioning unit for centralized water systems – R410A

The Frigomar Mini 30 (mod. 601NT) is a compact marine chiller designed for centralized air conditioning systems onboard. The unit combines small size, quiet operation, and advanced operational management, making it ideal for vessels where technical space is limited and reliability and precise parameter control are required.

Main features

Compact size and easy installation

The optimized structure (300 × 440 × 540 mm) facilitates integration in the tightest technical compartments, making the unit suitable for both new installations and refit interventions.

Quiet operation

Sound-absorbing panels and dedicated insulation effectively reduce noise and vibrations, contributing to onboard comfort.

Thermal insulation of cold parts

Heat exchangers and cold parts are fully insulated to prevent condensation formation, eliminating the need for a dedicated drainage system.

Advanced control with LCD display

The unit integrates a control panel with LCD display and a set of sensors for continuous monitoring of the main operating parameters.

Integrated sensors and protections

Complete equipment for system management:

• Temperature sensor
• Low pressure / high pressure control
• Water flow sensor
• Overload protection
• LCD control panel
