Gas detection in aluminium & steel production

With so many furnaces, pots and processes that emit hazardous gases, aluminium smelters and steel mills have significant needs for gas detection.

 

Each step in the steel making process – from coke production through ingot casting and rolling – has its specific hazards that must be addressed with a properly matched gas detection system.

 

Each step in the aluminium smelting process – from reduction through alloying and casting to homogenising and the production of recycled carbon anodes – has its specific hazards that must be addressed with a properly matched gas detection system.

Gas detection in pulp & paper production

With so many steamers, digesters, evaporators, recovery boilers, lime kilns, recausticisers,  screeners, refiners, washers, delignifiers, bleachers, chelators and processes that emit hazardous gases, pulp & paper mills have significant needs for gas detection.

 

Each step in the paper making process – from wood chip pretreatment through cooking and pulping to delignification and bleaching – has its specific hazards that must be addressed with a properly matched gas detection system.

Specific applications

  • Confined space entry
  • Inert gas blanketing
  • Data-logging/industrial hygiene – workplace exposures
  • Environmental
  • Perimeter/fence-line monitoring
  • Fixed point

Potential hazards

  • Chlorine
  • Chlorine Dioxide
  • Sulphur Dioxide
  • Hydrogen Sulphide
  • Volatile organic compounds
  • Combustible gases
  • Oxygen deficiency/enrichment

Entec provides a wide range of fixed gas detection systems and portable gas detectors for the pulp & paper industry to help keep employees safe and production running.

You can trust our expertise and rely on our service

We know your No. 1 priority is to protect your people and your plant. What you don’t want is to fail legal or OSH requirements, have a staff member harmed or be prosecuted for an accident. With an increasing focus on health and safety in the workplace, it’s more important than ever.

 

We understand the unique requirements of Central and Local Government. You don’t need the hassle and risk of gas detectors that are expensive, problematic, unreliable, prone to sensor failures, require too much servicing, or have recurring problems. We’ll provide you with gas detectors that are…

  • Cost-effective
  • Easy and reliable to manage on-site via function test / bump test stations
  • Serviced locally in our authorised service centre (the only one in NZ)
  • Backed up with our support and expertise
FAQs

Frequently Asked Questions

Depending on how they’re used there’s no reason a high-end instrument shouldn’t last 6 years. With low-cost instruments ($1,000) you will reach a stage where the gas detector is still fine but the cost of keeping it in the field is greater than buying a new one. For example, replacing two sensors and calibrating the unit could cost $1,100 but a new instrument is around $1,000.

All our instruments are IP rated (ingress protection rated). Typically IP67, which is very high. Gas detectors rated to IP67 must be dust tight and withstand immersion in water up to 1 metre deep for 30 minutes.

Solid particle protection level 6: No ingress of dust; complete protection against contact.

Liquid ingress protection level 7: No ingress of water in harmful quantity when the unit is immersed in 1 metre of water for 30 minutes.

See https://en.wikipedia.org/wiki/IP_Code for more info.

We can provide you with options from the top end to the basic. With our iNet InSite programme you get all the bells and whistles, all the basics like data-logging, bump testing and calibration; plus you get reports on instrument usage such as…

  • Instrument in alarm condition and alarm ignored.
  • Instrument turned off whist in alarm condition.
  • iNet Control.

iNet Control is a web-based application accessible from any PC web browser that allows you to configure and manage your gas detector fleet. It gives you practical insights into your gas detection program using trends, performance metrics and custom reports.

Yes. Calibrations done by us at our premises cost $140 per instrument.

Yes. All our instruments are independently tested by authorities such as ATEX, IECEx, ANZEx, UL, CSA and many more, usually country dependant.

New Zealand recognises the first 3. The gas detector has a sticker attached to it referring to the certification authority and its rating. Many have more than one authority rating, often 3.

Depending on sensor configuration and the number of gas detectors being purchased, the price varies from $950 to $4,500. The MX4, our most popular instrument, sells for $950 to $1,150 depending on configuration.

We process 95% of instruments the day they arrive. It does depend a little on the volume of work but we strive for same day turnaround whenever possible.

You would typically be looking at our MX4, MX6 and single gas models depending on the application, etc.

Yes. You would typically be looking at our MX4 model.

Yes. You would typically be looking at our MX4 model.

Yes, most definitely. On delivery we like to spend time with the users taking them through the basic use of the gas detector. We also like to spend time with the users of the docking stations teaching them how to use them. Industrial Scientific also has very good online training modules.

Case study: How many detectors did you say?

One customer ordered 18 detectors from us but they actually only needed 13. They wanted the other 5 to provide cover when detectors were sent away for repair and calibration because that’s what they’d been conditioned to expect with the previous supplier and brand of gas detectors they’d been using.

Entec sold them just the 13 they needed and they’ve been happy customers for 12 years now. They are currently on their second generation of instruments and about to update to their third. The gas detection instruments have been so reliable and they’ve been so happy with our quality of service that they will not be going to market.

Case study: A confronting explosion

A customer was having reliability issues with the instrument in use. It all came to a head when in a potentially dangerous atmosphere one of their gas monitors exploded. We were asked for a quote the next day and have been supplying our relieved client ever since.

Testimonial

It’s their whole trustworthiness. I was at a conference where a competitor of Entec approached me and said: ‘Hey, are you doing this…? Why don’t you do this? You need this.’ So I had a discussion and then I saw John and he said: ‘Yes, that’s okay and we can do that for you too, but what you do doesn’t really require that.’ So he had an opportunity to up-sell me but he didn’t because he knows the business we’re in. And he knows what we’re doing is right. So I value that. I don’t want to be just rung up every week and told of a new gadget that I need to get because the way I’m doing it’s wrong. I don’t feel that with Entec.
