What is R32 Refrigerant Gas? R32 is a refrigerant gas used in modern air conditioners and heat pumps. Its chemical name is difluoromethane (CH₂F₂). R32 is more energy efficient than older refrigerants, does not harm the ozone layer, and is used in homes, offices, and commercial cooling systems. It is slightly flammable, so it needs...

What is R410a Refrigerant Gas? R410a is a refrigerant gas used in most modern air conditioners and heat pumps. It is made by combining two gases, R32 and R125, and works like a single gas in normal conditions. R410a is popular because it works at higher pressures than older refrigerants like R22, which makes cooling...

What is R134a Refrigerant Gas? R134a is a type of hydrofluorocarbon (HFC) refrigerant gas, chemically known as 1,1,1,2-tetrafluoroethane (C₂H₂F₄), commonly used in vehicle air conditioning systems, domestic and commercial refrigeration, and some industrial cooling applications. It is a colourless, odourless gas that is non-flammable and low in toxicity, making it safe to handle under normal...

What is a Fume Hood? A fume hood is a local exhaust ventilation system designed to control and remove hazardous airborne substances at source. It works by drawing air away from the user and the working area, capturing fumes, vapours, gases, dusts, and aerosols before they can disperse into the surrounding environment. Typically used when...
