What Is a Retro-fit?
A Retro-fit is any modification made to an existing structure, system, or piece of equipment to improve its performance, safety, or functionality.
Rather than tearing something down and starting over, it's one of the most practical and cost-effective ways to bring older infrastructure up to modern standards. With an Engas Retro-fit, your existing air-conditioning unit is converted from harmful HFC gases to our natural hydrocarbon refrigerant.
The simple conversion normally takes 2 to 3 hours to complete and is carried out by qualified air-conditioning technicians in a safe and compliant manner. Once completed, the savings start the moment you restart the air-conditioner.
Quick Conversion
Typically completed in just 2-3 hours
Before You Convert
5 Things You Should Know
Easy Installation
Engas natural blended refrigerants are easy to install to your existing air-conditioning unit. The simple Retro-fit conversion normally takes 2 to 3 hours to complete.
Immediate Electricity Savings
Electricity savings are immediate and last for the life of the air-conditioner. The savings start the moment you restart the unit after conversion.

Manufacturers Approval
Engas Pty Ltd and our Authorised Distributors are often asked about air-conditioner manufacturer's approval for the use of Engas Hydrocarbon Refrigerants in their equipment. We have outlined our response below.
You Own It — It's Your Choice
Whenever people buy or pay off a piece of equipment — whether it be a car, mobile phone, refrigerator, or air-conditioner — they own it. They should be free to do whatever they want with it. Least of all, they should not have to seek permission from the manufacturer or a government body.
It is not up to the manufacturer to determine after-market practices. It is not the manufacturer of the equipment that decides whether Retro-fit conversions are suitable or not. This is a matter for a competent person experienced in the air-conditioning and refrigeration field, and also at the discretion of the owner of the equipment, subject to the competent contractor's advice and relevant standards.
Designed for their Equipment
Many manufacturers will say their air-conditioning or refrigeration equipment was not designed for hydrocarbon refrigerant.
This is not true — Engas hydrocarbon refrigerant is designed for their equipment.
This is, of course, subject to the equipment being in good order and passing a safety analysis. If the equipment cannot be Retro-fitted safely, then it should not be converted.
It is not a manufacturer's duty to approve all possible materials, parts and components that might be used in ongoing air-conditioning or refrigeration systems during their life span. In a fast-changing world, it is often impossible to anticipate all subsequent ongoing improvements involving parts and materials. Typically, manufacturers will only approve the use of original equipment manufacturer parts for obvious commercial reasons.
Warranty Protection
Your Warranty Is Protected
Australian Law prohibits manufacturers from denying a warranty claim even if equipment they've manufactured has been upgraded or modified.
Better for Your Machine
An air-conditioning system converted to Engas Hydrocarbon Refrigerant by a properly trained technician will not cause damage to that machine. In fact, it will be better for that machine and the owner will save a substantial amount of money in electricity consumption costs for the life of the machine.
Engas 12-Month Warranty
Engas Pty Ltd will cover any damage directly attributable to the use of any Engas Hydrocarbon Refrigerant for a period of 12 months from the date of installation by a properly trained refrigeration technician.
Warranty Claims
Should service be required under the terms of this warranty, please contact the engineer or technician that installed the Engas Hydrocarbon Refrigerant. They can only deny warranty if the modification reasonably contributed to a fault.
Busting the Flammability Myth
Note: ALL Air-Conditioning Refrigerants Burn!
When a chemical or natural hydrocarbon refrigerant is installed into an air-conditioner, it is immediately mixed with oil inside the unit. Should any air-conditioner leak near a power source, the refrigerant may ignite and burn. It is the combined oil/refrigerant that burns — oil is the first to ignite as it has the lower auto-ignition temperature (260°C).
Chemical Refrigerant (R32)
Dangerous goods classification: 2.1 — Highly Flammable
When burned, produces highly toxic fumes — very bad for the environment and human health.
Natural Hydrocarbon (Engas)
Dangerous goods classification: 2.1 — Highly Flammable
When burned, produces carbon and steam — not toxic, will not hurt the environment.
Chemical refrigerant R32 has the same dangerous goods classification as hydrocarbon refrigerants — effectively nullifying the competing focus on hydrocarbons being more flammable. The key difference? Chemical refrigerants produce toxic by-products; natural hydrocarbons do not.
We already use flammable hydrocarbon products safely every day — in air transport, vehicle transport, cooking, heating, deodorants, and more. Hydrocarbons do NOT spontaneously combust on contact with air. All refrigerants are to be installed by a competent person at all times.
Quality Assurance
Certified Purity in Excess of 99.5%
All Engas Pty Ltd natural Hydrocarbon Refrigerants are certified and guaranteed for purity in excess of 99.5%.
Because of lengthy and precise filtration and distillation processes, contaminant levels of sulphur, oxides and moisture are kept well below normal industry standards for refrigerant gases. We well exceed all maximum purity levels called upon by system and component manufacturers throughout the world.
Typical hydrocarbon base stocks contain high levels of n-butane, iso-butane, propylene, ethane, pentane, and other hydrocarbons that alter the pressure/temperature relationship. Unless these contaminant levels are carefully controlled or eliminated, consistent performance data is almost impossible to maintain.
Using any low-grade refrigerants can ruin the performance and reliability of a refrigeration system and cause serious damage to equipment. At Engas, we always ensure that high-quality and consistent refrigerant blends leave our factory.
Using industry standard procedures and installed correctly, Engas Hydrocarbon Refrigerants will never cause corrosion to system components or copper tubing.

Important Facts
Hydrocarbon Refrigerants are promoted for use by the United Nations Environment Programme.
Hydrocarbon Refrigerants are recognised as proper refrigerants by the world's leading HVAC industry bodies such as ASHRAE & AIRAH. They are given designated 'R' numbers such as R290 & R600a.
Hydrocarbon Refrigerants are environmentally friendly.
Hydrocarbon Refrigerants are energy efficient.
Hydrocarbon Refrigerants have lower operating temperatures and excellent lubricating properties — compressors run cooler, quieter, and with less vibration.
