Argon Gas for Food Preservation

Most people think of welding when they think of argon gas. In fact, argon is a safe, benign gas which can be used to preserve wine, food and historical documents. For some time nitrogen was the ‘go to’ gas when it came to extending the shelf life of packaged goods but scientists have found that argon is actually 4 times more efficient than nitrogen, it is also around 40% denser than air and improves food safety. Thus argon is more effective than nitrogen in keeping food fresher for longer and improving its quality. So how does it work? Gas is used to replace oxygen which not only causes food to oxidise and spoil but allows bacteria to grow. Argon removes the oxygen very efficiently compared to nitrogen as it is denser and is able to more completely fill the spaces around food. Bacteria is starved of oxygen and enzymes that increase the rate of oxidation are inhibited. The use of food grade argon as a preserver does not add anything to the original product, rather it stops it from going bad in a completely safe way. Rent Free Gas is able to supply customers with food grade argon for a multitude of uses including the preservation of food and wine. Our rent free model allows our customers to purchase their own argon cylinder which they will never pay any rent on...ever! The cylinder will come completely full of gas and delivered for free in Sydney, Brisbane and Adelaide. Whenever more gas is needed we will simply come out and replace the empty argon cylinder with a full bottle. If a smaller c size cylinder is all you need we can post it to you anywhere in Australia. Give us a call and let one of our friendly team help you out with your argon gas needs today. 

Nitrogen Gas Delivery

Nitrogen Gas Cylinder Delivery in Sydney When you own one of our Nitrogen gas bottles or a Speedgas Nitrogen gas cylinder, you can stop paying rent immediately. If we give you a refill price, there is no more to pay, there are no other costs. We cannot refill BOC, ALA, Supagas or Coregas cylinders. We cannot refill BOC, ALA, Supagas or Coregas cylinders. Our customer base is growing very quickly and the two main reasons for this are that we keep things simple (for example, no invoicing issues), and also because we are saving our customers money. We ask you to think about how long you have had a cylinder sitting in the workshop, garage, factory, shed or office? If the answer is a long time (more than a few years) to that question, then you should send the bottle back to your supplier and buy a bottle of your own. Information provided from customers who have purchased their own bottle (that comes with no rent and no delivery), is that after about 12-14 months they have saved money. Their rental costs vary between $10-$25 per month which is $120-$300 - just for rental. So once you add in the gas cost on top of that rental, you are normally in front after 1 year. The next key question is how often you refill that Nitrogen bottle? If your answer is not very often (let's say a few times per year) then you should definitely review your refill costs and give us a call. We will match the big guy's price, and do a deal to get you saving money today. There are no tricks or hidden costs with Rentfreegas and Speedgas, we are a small and nimble AUSTRALIAN business that wants to talk to you and help you with great service, and also help you lower your nitrogen costs. If you would like more information about rent free gas bottles or how to lower industrial gas costs in your business, feel [...]

Introducing New Nitrogen Gas Kit

Nitrogen Gas, Regulator and Hose Kit Nitrogen Gas & Reg Kit We have recently put together a Nitrogen gas kit, which includes a new refillable bottle full of gas, with a new Nitrogen regulator (Type 50 valve outlet) and an inert gas hose rated to 1500kpa.  The kit price also includes GST and delivery to you, so for $310 you can own a refillable gas cylinder, regulator and hose, delivered to you. In some kits we have already supplied customers, they requested for us to attach a simple low-pressure air gun with a trigger mechanism to the other end of the hose. The airgun allows customers to pulse quick or long bursts of nitrogen into bottles, bags and food containers for purging, or to fill other items and balloons quickly. Nitrogen is used in many areas and industries, some of these include, automotive for filling car tyres, food & wine preservation, welding, aviation, fire protection, refrigeration, fumigation, and for purging lines, oxygen depletion, plastics welding and much more.     Once you own your own Nitrogen gas bottle, you never pay cylinder rental again. When the bottle is empty you place it back into the box it arrived in and return it through the post, then purchase your C size cylinder 'refill' from our store at http://www.rentfreegas.com.au/shop/nitrogen/ which costs $70. Then the following day we send you a full bottle. If you have any questions, please feel free to call us. Regards, www.rentfreegas.com.au Phone: 0404 677 187

Helium Hire & Delivery to You – Sydney.

Helium balloons are definitely not just for kids anymore. Beautiful helium balloons are being used everywhere. The latest trends in helium balloons are centred around stylish creations using giant 3 foot balloons, balloons with tassels, confetti balloons and letter balloons. One of our customers recently had 3 foot balloons on strings coming out of the pool, and they looked amazing! You can now easily get your inspiration from an abundance of websites showcasing stunning helium balloon decorations such as Lenzo and Pinterest. It is then very simple to source these gorgeous balloons and accessories which many stores deliver to your door at no extra cost. There is a problem though:  How do you get the helium to inflate these beautiful balloons? balloon gas cylinder Party stores are becoming harder and harder to find and those that exist are often not in a convenient location close to you. These stores generally do not deliver or pick up helium tanks. If you can convince them to help you out you will pay a hefty price for delivery.  Of course there are disposable helium cylinders but they are terrible for the environment as they can not be recycled, they might just fill one 3 foot balloon, and we recieve calls from customers who need more gas, as the disposables did not fill all the balloons in the pack. So how do you take advantage of the huge choice of gorgeous helium balloons out there but get your helium too? That is where Rent Free Gas can help you out! We understand that you might not want to buy a helium cylinder of your own so we now offer the hiring of our helium cylinders. We are very happy to bring helium to your door for all of your short term needs. We know how precious your time is. Let us make it very easy for you. Simply choose the cylinder size you need, pick a drop off [...]

Stop ignoring your bottle rental costs

No More Welding Gas Bottle Rental Fees. Time and time again we talk to gas users who are fed up with the ridiculous rental fees they are paying on their gas cylinders. So many people feel locked in because they are unaware they can buy their own bottles and have them filled and swapped over easily without ever having to pay rent again. There are concerns about the initial cost, and whether it is cheaper to rent in the long run or if a customer will always be able to get their own cylinder refilled, or will they be stuck with it after a few years and then have to return to the rental system. If you work the numbers it is clear that paying rent only benefits one party and that certainly is not the end customer. Large gas companies have high costs which must be passed onto their customers in order for them to achieve their profits. Rental charges on bottles are a great profit generator for the gas companies. There is no advantage for you in the short or long term. They use scaremongering tactics to convince you it is in your best interests to continue paying rent. All gas companies should conduct tests on the cylinders and they include, visual, Hydro and ultrasonic testing. So regardless of who the gas company is they must provide a safe cylinder for the customer. Smaller gas companies like Rent Free Gas are in a unique position with lower overheads, more efficient customer service and simple delivery methods which mean we can offer you a whole new way of buying and using gas. We don’t need to charge you rent, we don’t want to charge you rent. We want to provide you with a competitive gas supply option that is fair. One of the main queries we receive is whether we will always be here to refill your bottle. Rentfreegas has been going for nearly [...]
