Maintenance & asset management 

Having over 20 years experience in servicing Industrial & Marine refrigeration, we have been exposed to a multitude of Ammonia systems all over the world, regularly in high pressure situations. We believe that Safety and Maintenance go hand in hand. whether you require the development of a management dossier or simply wish for us to provide an independent review of your facilities operational status, we are here to help you. 


It is no surprise to business owners,  taking your top technicians off the road to train, manage & assess the apprentices evidence requirements is a costly exercise.
It is also no surprise that kinetic personalities are not meticulous with their paperwork.
Gauge Refrigeration Management Ltd are passionate teachers whom can deliver training solutions that are safe, technically astute & match unit standard criteria which can result in final assessment approval of the trainee.

We can then formulate & manage the evidence gathering process which will provide your young technician with techniques of filling documentation efficiently.

Pre-employment screening 

Regardless of the quality of the CV and the success of the interview process, judging someone in a very short space of time can be difficult & for the applicant a stressful time.

Gauge can provide assessment of a refrigeration technician at any stage but in the aid of ensuring you make the right call, for your own piece of mind why not save the guessing game & know they can perform as well as they say they can in a detailed & structured pre-employment assessment.

Contractor network 

We have a large network of some of New Zealand’s finest independent service technicians.
There are less than two Ammonia Technicians in every hundred thousand people so we personally know there special skill sets & abilities because we have worked together at some stage in our careers therefore we will only direct you to the right technician.

They are passionate about what they do not only because they have a vested interest in there buisness but they actually care about the quality of their workmanship & enjoy the technology of the trade.

If you have any refrigeration task no matter how big or small we are content in providing you with their details.

24/7 service activities are not the niche of Gauge Refrigeration Ltd, we are however happy to meet your needs of maintenance & asset management  as well as any diagnostics that may require an independent review.
