The PERFECT Gas Leakage and Measuring Solution for fruit Ripening and cold storage application

The Season of juicy sweet fruit mango’s comes, we in cold storage and Fruit Ripening chamber started working on it, in this period we dosing/use  mango with ethylene gas and ammonia gas for ripening and storage and we all need to control & measure the amount of ethylene & ammonia we are supplying also need to aware about its leakage in open environment to control any hazardous incident, for all related solutions you can contact us any time .

ALVI Automation (India) Pvt Ltd in Association with GasAlarm Systems based in Sydney, Australia and MSR Germany specializing in gas detection & monitoring solutions with over 40 years of experience in the industry we like to think we know a little about the industry and how its , changed over the decades what we found lacking was good quality reliable products which were low cost, especially for the developing/emerging markets & countries.

So, we’ve taken it upon ourselves to slowly introduce such products one by one.

We dedicated to start with the most common product in gas detection worldwide, the humble ethylene and ammonia sensor Transmitter.

Countless brands, models & technologies exist however we feel ours has hit the spot when it comes to the all-important price/performance ratio.

We’ve kept it extremely compact! We’ve kept it extremely simple!

We’ll be honest, our aim is to sell this product at extremely low margins however in large quantities.Thus, ensuring you, the customer keeps buying and sees the value add in the product locally

Introducing the Ethylene/Ammonia Sensor Transmitter

  • The all-in-one sensor/transmitter is made in Germany under an OEM exclusive agreement for us.
  • It uses an Electro-chemical sensor cell. NOT semi-conductor or MEMs semi-conductor.
  • It offers an industry standard measuring range of Ammonia 0-1000 PPM and Ethylene 20-2000 ppm
  • It runs on an industry standard 2 wire 24VDC current loop with a 4-20mA output.
  • It has 2x onboard potentiometers for future on-going calibrations, A zero & a span/gain pot.

Ethylene (C2H4) Gas Detector for Fruit Ripening Application

What is Ethylene(C2H4)?

  • Ethylene (C2H4) is a colorless gas which is highly flammable with a Lower Explosive Limit of 2.7% in air.
  • Measuring range: 20-2000 PPM, 0-200 PPM, 0-100% LEL C2H4 with Semiconductor and Electrochemical Sensing Technology
  • Studies have indicated a low toxicity of ethylene and no risk to human health has been identified. It is naturally occurring, but it can also occur as a result of combustion and is manufactured by industrial processes from Methane and petroleum.
  • It has a slight ‘musky, sweet’ odour. Some fruit will produce C2H4 as ripening begins. Apples and pears are examples of fruit that produce ethylene with ripening. It is responsible for the changes in texture, softening, colour, and other processes involved in ripening.

Where is Ethylene (C2H4) Used?

C2H4 is widely used in the chemical industry. Polyethylenes of various density and melt flow account for more than 50% of world Ethylene demand. The primary use of polyethylene is in:

  • film applications for packaging, carrier bags and trash liners.
  • injection moulding
  • pipe extrusion
  • wire, cable sheathing and insulation,
  • extrusion coating of paper and cardboard.

C2H4 is the starting material for the preparation of a number of two-carbon compounds including Ethanol, Ethylene Oxide or converted Ethylene Glycol for antifreeze and Polyester fibres and films and Vinyl Chloride (converted to PVC). In addition to these compounds, ethylene and Benzene combine to form ethylbenzene, which is dehydrogenated to Styrene for use in the production of plastics and synthetic rubbers.
