Solutions & Services

System design & installation

We design commercial refrigeration systems around how your business actually operates - capacity, layout, workflow and budget - then install them to spec, from single cool rooms through to multi-site refrigeration plant.
Servicing & Maintenance

Scheduled servicing catches small issues before they become expensive ones. Our maintenance programmes are built around your equipment, your compliance obligations and your operating hours.
Breakdown & Emergency

Refrigeration failures don't wait for business hours. We offer 24/7 Nationwide Support to get you back up and running with minimal disruption and product loss.
Refrigerant Management

We manage leak detection and refrigerant reporting in line with New Zealand regulations, including the ongoing phase-down of high-GWP refrigerants - so your systems stay compliant as the rules evolve.
Energy Efficiency Upgrades

Ageing refrigeration is often the biggest energy draw on site. We assess existing plant and recommend upgrades that cut running costs without cutting performance.
Cool Rooms & Cool Store

From large processing facilities to small-scale producers, Cryvex delivers commercial coolstore and packhouse refrigeration built to protect the hard work you've already put in. Whatever the size of your operation, we have a fit-for-purpose cooling solution.

Frequently asked questions

Yes, Cryvex will service and maintain systems regardless of who installed them originally.
Older refrigeration plant is often the single biggest energy user on a commercial site. We can assess your existing system's performance and running costs and recommend upgrades where the numbers stack up.
Common signs include inconsistent temperatures, unusual noises, ice build-up where it shouldn't be, rising energy bills, and the compressor cycling more frequently than usual. If you notice any of these, it's worth getting a technician to look at it before it becomes a full breakdown.
Refrigeration system optimisation means improving how your system performs. This can include servicing, refrigerant upgrades, precooling, insulation, monitoring and other changes that improve reliability or efficiency.
We work with the refrigerant types appropriate to each system and manage handling, leak checks and reporting in line with New Zealand's environmental regulations, including the ongoing shift away from high-GWP refrigerants. If you're unsure what's in your existing system or what your obligations are, we can help you assess that.
We offer 24/7 emergency callout support for urgent breakdowns, because refrigeration failures don't wait for convenient timing.

Yes. Cryvex technicians are trained to work with the latest low-GWP refrigerants, including A2L refrigerants, which are becoming the standard as older high-GWP gases are phased down. Whether you're installing a new system or upgrading an existing one, we'll help you choose a refrigerant that's efficient, compliant and ready for the future.
