Browse through our stories on how Neptune Refrigeration maintain excellence in our field
Blue Whaler | January 2024

Neptune Refrigeration tradesman Lochlan undertaking the final steps of commissioning a new custom system onboard local charter vessel, ‘Blue Whaler’. This upgraded freezer system is designed to handle the daily catches expected on the upcoming fishing expeditions, providing unmatched, capacity and efficiency. We think this unit turned out great!

Kekoa| December 2023

Another happy client. Neptune Refrigeration have had a long-standing relationship with Luke and his team on board Kekoa.

This time we diagnosed a faulty compressor in Cairns travelled to our Airlie Beach branch with the new component and fit it off once they came down the coast.

Commissioned and running again the system is steadily cycling at -15°C, preserving their marlin baits for the upcoming fishing season.

Reef Tourism Condensing Units | November 2023

Neptune Refrigeration has successfully completed the installation of two custom built condensing units on a local reef tourism vessel.

These units were meticulously, constructed in house to perfectly fit the available space on board. Using a crane, both units were placed in parallel, followed by the necessary, fitting off and commissioning.

To ensure easy maintenance and accessibility to controls and variable speed drives, the new systems are safeguarded by an aluminium cover with removable panels. This design allows for convenient access whenever adjustments or inspections are required.

The project showcases the team’s dedication to position and innovation, particularly in the marine and tourism sectors. Let us know what you think below!

Superyacht Custom Freezer | October 2023

The moment has arrived!

Neptune Refrigeration previously shared a glimpse on social media of our team members, Drew and Tom, diligently preparing panels for the construction of a custom freezer, and now we can showcase the final results onboard a Superyacht.

The unique challenge with this freezer was to design in a way that allowed us to fully assemble it in our workshop, disassemble it, navigate each panel through the narrow passageways of the vessel, and then reassemble it on board. This system incorporates static coils constructed from polished 1/2” copper tubes capable of maintaining -20° Celsius inside.

To ensure optimal functionality, the condensing unit was skilfully positioned within a serviceable cupboard thoughtfully designed with grills on both sides to facilitate proper airflow.

We are quite pleased with how this project turned out, and we are curious to hear what you think!

Water- and Air-Cooled Condenser Project | September 2023

See the before-and-after photographs, illustrating the replacement of a refrigeration unit in one of our recent projects.

This vessel frequently navigates through muddy waterways, and occasionally requires both its water-cooled condenser and in-series air-cooled condenser to prevent the occurrence of high-pressure faults.

As part of the upgrade, we applied a two-pack paint coating to the new system and incorporated a custom-designed shroud. This shroud is designed to optimise air circulation through the air-cooled condenser coil.

Bitzers Galore | August 2023

Neptune Refrigeration are currently amid fabricating racks, pipework and electrical boxes to suit some new installations we have coming up.

These new systems will serve to provide maritime vessels with air conditioning and refrigeration capabilities that exceed their current systems in a multitude of ways.

Some facets we always try to improve on include longevity, efficiency, serviceability and aesthetics.

Respond Global HelpR Program | May 2023

Neptune Refrigeration tradesman, Drew Mitchell our qualified Refrigeration and Air Conditioning Mechanic specialised in marine refrigeration was sent to Vanuatu in May 2023.

Drew was sent to the vessel to fix the airconditioning onboard that had not been operational for 3 weeks. The vessel, Helpr needed to replace the generator onboard, a control component for their cold rooms that kept the necessary medicine in a cool climate.

The vessel, Helpr was positioned to go to Vanuatu to support the islands as part of their cyclone response, to provide fresh water, rice, medicine, and medical support. The crew onboard consisted of Phil the Captain, Doctors, Nurses, and other volunteers.

When onboard a Helpr vessel, it really is all hands-on deck with Drew more than happy to assist the team with delivering items to the locals. The vessel was also dropping off locals back to their villages once the cyclone had subsided.
