What are Hydrocarbons?


Hydrocarbon refrigerants are environmentally friendly, non-toxic, non-ozone-depleting replacement for chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). From a chemical point of view, a hydrocarbon is the simplest organic compound, consisting entirely of hydrogen and carbon. Hydrocarbons (HC) are naturally occurring substances. The majority can be found in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen.

What advantage do they have over other refrigerants?

Hydrocarbons are one of the most climate-friendly and cost-efficient refrigerants to heat, cool and freeze:

  • Non-ozone depleting: Ozone Depletion Potential = 0
  • Not climate damaging: Global Warming Potential = Most Hydrocarbons have a rating of 3 as compared to some synthetic refrigerants that have a Global Warming Potential of 3,260
  • Non-toxic
  • Safe: with proper handling
  • Energy-efficient: usually better energy efficiency than CFC or HFC systems
  • Easy replacement: able to replace many gases in existing systems without the need to change components or oils
  • Cost-efficient: low refrigerant purchase price as well as lower system running cost.

These types of refrigerants are endorsed by the GreenPeace organization and are in full compliance with the UN Montreal Protocol.

Are hydrocarbon gasses new?


No. They have been in use since before ozone-depleting CFCs were developed and were re-introduced for use in heat pumps after the CFC phase-out. Their thermodynamic data, efficiency, and material compatibility are well known. In some countries, appliance manufacturers and food producers began using hydrocarbon replacement gas in appliances shortly after 2000, due to environmental concerns.


Which gasses can hydrocarbons replace?


Hydrocarbons can replace many obsolete CFCs, HCFCs, and HFCs, including the ozone-depleting refrigerants R12, R13, and R22 in domestic, commercial and industrial refrigeration, and car air conditioning. It is also a substitute for R134a, R404a, R407c or R502a in fridges, freezers, cascade supermarket systems, heat pumps, and chillers.


Is Coolant Express Refrigerant approved by the US EPA?

Coolant Express Refrigerant does not fall under or within the guidelines set forth by Congress concerning global warming or ozone depletion because it is an environmentally safe, non-global warming and non-ozone depleting product.

According to the US EPA website, under the SNAP rule, the EPA regulates/reviews substitutes for CFC R12. Direct replacements for CFC R12 are called “first generation” substitutes. HFC 134a is a replacement for R12 because it does not threaten the ozone layer and, therefore, it is a “first generation” replacement. Enviro-Safe Refrigerant is considered a “second generation” substitute for HFC 134a and other CFC R12 substitutes.

Therefore, Coolant Express Refrigerant does not require “approval” to be used or sold as a HFC 134a or other CFC R12 substitute.

Are Hydrocarbons safe?

Yes, with proper handling. Since hydrocarbons are flammable, some basic safety rules need to be respected by manufacturers, installers and users, which may differ slightly depending on the application. As long as these rules are respected, it is perfectly safe to use hydrocarbons as refrigerants. Propane, for example, is used universally for heating and cooking. As a result, its safe handling is widely understood

and practiced by the general global population. This makes it an appropriate alternative to climate damaging chemical refrigerants.


Will using Coolant Express void my warranty?


No. Under the Magnusson Moss Act, there is protection for consumers that states that if a manufacturer requires you to use their products to uphold their warranty; they have to legally provide at no charge to the consumer those products.  Please see the attached link for further details of this act: http://en.wikipedia.org/wiki/Magnuson-Moss_Warranty_Act


Is Coolant Express Refrigerant flammable?

First and foremost, it is important to recognize that all refrigerants containing hydrogen including the popular R22 and R134a are potentially combustible under certain conditions.

All gas, even R22, is flammable and the right precautions need to be taken when using any refrigerant product. In refrigeration and air conditioning systems which currently use chemical refrigerants, oil is used to mix with the refrigerant and travel around the system. Therefore, all of these chemical refrigerants also become flammable due to the oil vapor content of the gases when being discharged from the systems.  Hydrocarbon refrigerants do not spontaneously combust on contact with air! There are 3 elements that all need to coincide at the same time:

1.   Hydrocarbons will need to be released.

2.   The correct proportion of air needs to mix with the Hydrocarbon, the range of flammability generally being 1.9% to 8.5%. Combustion cannot occur outside these limits.

3.   There needs to be some type of ignition source, which exceeds 598°C. If any 1 of these 3 elements isn’t present, then the combustion cannot occur.

Generally if there is a leak in a system, only a small percentage of refrigerant will leak out, not the whole amount. Then due to the Hydrocarbon being able to dissipate so quickly, it would be extremely difficult to meet the range of flammability.

Hydrocarbon gas is rated as a Flammable Gas 2. This means there is a moderate chance of fire or flame. However, flammable products are used every day within the household, business and in automobiles.

Aerosol products such as hairspray, room deodorizers, under arm deodorant, penetrating oil, WD 40, etc. are all classed as a flammable and are used all over the USA and the world as a safe product in home and automotive used when used as per manufacturer directions.

Hairspray = Flammable 3, Gasoline = Flammable 4, Starting Fluid = Flammable 4, Coolant Express Refrigerant = Flammable 2.  Coolant Express Refrigerant can be used safely in automobiles and A/C units. All flammable products require your respect, adequate precaution and safe use practices. Follow all directions on the can or label.


What is the difference between Coolant Express and HFC-134a or R-12?

Coolant Express is an all-natural, non-ozone depleting material with 0 global warming potential.  In fact, it is so pure; it is classified as a pharmaceutical grade product! R-12 and HFC-134a are man-made, chemical refrigerants that do not utilize all natural products. R-12 has both, high global warming and high ozone depletion, while HFC-134a does not affect the ozone, it does have a very high global warming potential according to reports.

Additionally, manmade chemical refrigerants can contain higher levels of impurities that can cause:

  • Moisture /acid buildup;
  • Reduction of Cooling Capacity;
  • Increased energy consumption
  • Increased working pressures.


What about energy efficiency?


Yes! Hydrocarbons are more energy-efficient than most conventional HFC or CFC systems. Used in residential air conditioning units, hydrocarbons have reported to be in the range of 20-40% more efficient than synthetic refrigerants.

Hydrocarbon gasses are Non Toxic and do not generate toxic by-products when exposed to heat in the presence of oxygen.  They are a viable organic replacement for R22 and R134a. Hydrocarbons are  blends of natural organic materials that have molecular advantages over synthetic refrigerants as their molecules are lighter than and not as dense as synthetic refrigerants. Therefore, the “fluffier” molecules absorb, conduct and release heat better and can be compressed much easier.

Their molecular advantages, lend themselves to more efficiencies as they require considerably lower high side pressures than R22 or R134.  Lower operating pressures mean a longer compressor life and fewer leaks. Additionally, hydrocarbons have been tested and have reported energy savings in the range of 20-40% more over synthetic refrigerants. A full charge is achieved at approximately half the weight required by traditional refrigerants. An additional advantage is temperature glide; i.e. meaning that they release heat more evenly across a condenser and absorb heat more uniformly across an evaporator. This is unlike synthetic refrigerants like R22 and R134 that condense at one temperature and basically dump their heat in a small area leading to condenser wear.

Hydrocarbons are governed by International Purity Standards and must contain low levels of contamination as the presence of impurities in refrigerants can cause:  Moisture/Acids; Reduction of Cooling Capacity; Increased Energy Consumption; and Increased Working pressures.

Hydrocarbons must meet the following Purity Standards as required by DIN 8960:

Purity Greater or equal to 95.5 * % Mass
Non Condensability Less than or equal to 1.5 %
Humidity Less than or equal to 25 (mg/kg)

Coolant Express products meet and or exceed these stands, and are refined to the point where they are considered to be pharmaceutical grade.

Can I lower “head pressure” in my air conditioning system by using Coolant Express Refrigerant?

Yes! Coolant Express can extend equipment and component life by lowering compressor “head pressure” up to 33%. In most cases, Coolant Express is capable of delivering energy savings and will result in a considerable reduction in operating costs!


Can hydrocarbons be used in existing systems that use HFC’s?


Yes. However, you cannot mix Coolant Express Refrigerant with R-12, R22, R502a or HFC 134a. Although mechanically there is no risk of incompatibility or damage, there is legislation in place in the U.S. that prohibits such acts.  The US EPA prohibits the mixing of ANY refrigerant within the United States.  In the United States, it is illegal to mix any two or more refrigerants no matter what brand it is.

This does vary for other countries.

Is it legal to use Coolant Express Refrigerant in automotive applications?

Yes, in most countries throughout the world.

However, in the United States, the US EPA adopted the SNAP (Significant New Alternative Policy) concerning R12 systems, global warming and ozone depletion.  Pre-1994 mobile air conditioning systems operated on CFC R12, which has been ruled environmentally unsafe because it contributes to global warming and ozone depletion.  All R12 systems must be retrofitted prior to using any alternative or environmentally safe refrigerant.  Please note:  In the United States, Coolant Express Refrigerant is not a drop in replacement for R12.

Coolant Express Refrigerant may be used to replace HFC 134a and R12 substitutes in the majority of states within the United States.  We advise that you refer to your local, state and federal laws governing the sale and use of any refrigerant.

Are Coolant Express Refrigerants corrosive to air conditioning systems?

No! Coolant Express Refrigerants are non-corrosive, and do not form acids in combination with system moisture.

Is there an odor?

Yes, Coolant Express contains a “fresh pine scent” which is added during the bottling process. The “fresh pine scent” was designed to assist consumers in leak detection. The “fresh pine scent” immediately notifies the operator and others within the vehicle of a leak within the air conditioning system.

Is Coolant Express Refrigerant compatible with all refrigerant oils?

Yes, Coolant Express is totally compatible with all refrigerant oil available today. It can be used with Mineral, Ester and PAG oils without incompatibility.

Are Coolant Express Refrigerants energy efficient compared to other refrigerants on the market today?

Yes! They can be up to 40% more efficient than Hydrofluorocarbon (R12 and R134a) refrigerants.

Stop Leak

Will Stop Leak harm my air conditioning system?

Absolutely not when used according to manufacturers specifications.

Can I use Stop Leak in both HFC134a and CFCR12 systems?

Yes. Coolant Express is compatible with both systems.

Pro Seal

How large of a leak will ProSeal repair?

If the leak does not empty the system within 24 hours. ProSeal will typically seal the system with one can. However, two cans or more cans may be necessary if leaks persist. (This Information does NOT apply to industrial systems.)

Will ProSeal intermix with all refrigerants?

Yes! ProSeal mixes with all hydrocarbon and chemical (R12, R134a, R502, R22) refrigerants.

Will ProSeal perform in all systems?

Yes! ProSeal will seal most leaks when used according to the manufacturer’s directions. ProSeal will seal most small holes located in the air-conditioning condenser, evaporator, fittings, and metal lines. ProSeal wil NOT repair O-rings or seals. For application regarding O-rings or seals we recommend Coolant Express Stop Leak.

For larger systems, please contact us with questions. .

Will ProSeal damage recovery units?

ProSeal will not damage reclaiming equipment that has been maintained to manufactures recommendations.  The reclaiming equipment must be free of all moisture (water) and air.

Please note:  ProSeal is a highly concentrated product.  We use only a small amount in our containers, thereby, also reducing the chance of damage.
