BEVERAGE & MAP GASES

We have a range of mixed gas options that can be tailored to suit your exact food, beverage or packaging application and can be supplied in a variety of cylinder sizes. All mixed gas cylinders maintain mixture consistency, right up to the point at which the cylinder is empty.

CERTIFIED GAS MIXTURES

We have access, through several independant gas suppliers, to an extensive range of certified gas standards. Available in either low pressure lightweight aluminium or high pressure steel cylinders. Manufacturing times, on average, are shorter than those available elsewhere.

CRYOGENIC LIQUIDS

We have a range of cryogenic/refrigerated liquids in a variety of cryogenic containers to meet most applications. We can offer delivery, pick-up and refilling services of privately owned containers, or alternatively we can fill at our head office for your convenience.

INDUSTRIAL GASES

We have access to an extensive range of mixed or pure gases to suit any industrial application. Gas mixtures can even be tailored to your “one off” applications in-house. Cylinder sizes have been standardised to simplify identification and re-ordering.

CRYOGENIC CONTAINERS

We now have the ability to supply a complete range of cryo-containers through INOXCVA, for a variety  of applications which includes dry shippers, long term storage or transport containers. We can also offer 2 styles of liquid level sensors/alarms for peace of mind storage.

CRYOGENIC LEVEL SENSORS

We have access to 2 types of level indicators. Installing a level indicator means that with a simple glance, you can accurately know exactly how much cryogenic liquid you have available to use or alternatively, how much sample storage time you have remaining.

NITROGEN GENERATORS

Generate Nitrogen with purities from 95% – 99.9995% pure on site as required from thin air. Each system is sized to meet your exact requirements which means less initial capital outlay and faster payback.

OXYGEN GENERATORS

Generate Oxygen gas onsite as required from thin air. Oxygen is available at purities up to 93% pure, from a few litres per minute to thousands of litres per day. Fully automatic portable units to large industrial installations are available.

GAS BLENDERS

Accurately blend any mixture of gases either statically or dynamically with fixed or variable concentrations. Increase the versatility of 2 pure gas cylinders by blending multiple mixes onsite rather than having multiple cylinders, each dedicated to a single task.

REGULATORS

We pride ourselves on working with only the world leaders when it comes to industrial and speciality gas equipment. We understand that having all of the right equipment when you need it is crucial to completing your job on time and within specifications.

CYLINDER TESTING

We are an IANZ Accredited Cylinder Testing Laboratory certified to test high pressure industrial gas cylinders. We specialise in testing our own cylinder fleet however, we are able to provide our customers with a test and fill option to provide a one stop shop gas convenience.

GAS ANALYSIS

We are currently in the process of setting up a GC/MS laboratory, specifically for analysing non-reactive and reactive gases, along with common EPA and air monitoring gas mixtures. Our ultimate goal is to become IANZ accredited and manufacture certified gravimetric gas standards.

GAS BLENDING

We are able to manufacture highly accurate uncertified gravimetric gas mixtures on site, at our Christchurch head office. These mixtures can then be calibrated against a known certified standard and are ideal for situations where large volumes of calibration gases are required.

OWNERSHIP CYLINDER FILLS

We offer an ownership cylinder gas fill service  (*Conditions apply), onsite at our head office in Christchurch. We have a variety of pure gases available such as Argon, Carbon Dioxide & Oxygen and gas mixtures consisting of Argon/Carbon Dioxide available to suit most welding applications.
