Refrigerant gas is a specialised fluid used in air conditioning, refrigeration, and heat pump systems to transfer heat. It absorbs heat from one area and releases it elsewhere through a continuous cooling cycle, making it possible to maintain controlled temperatures in residential, commercial, and industrial applications.
Refrigerant circulates through a closed-loop system, changing between liquid and gas states. As it evaporates, it absorbs heat from the surrounding environment. It is then compressed, condensed, and cooled before repeating the cycle. This continuous heat transfer process is what enables refrigeration and air conditioning systems to operate efficiently.
Refrigerant is the working medium that makes cooling possible. Without it, HVAC and refrigeration systems cannot remove heat effectively. Using the correct refrigerant also improves energy efficiency, extends equipment life, and ensures compliance with environmental regulations.
DewGas offers a comprehensive portfolio of refrigerants for residential, commercial, industrial, and automotive applications. Our range includes HFC refrigerants such as R32, R410A, R134a, R404A, R407C, R438A and other industry-approved refrigerants, with infrastructure designed to support future lower-GWP refrigerants as the market evolves.
Refrigerant gases are widely used across residential air conditioning, commercial HVAC, cold storage, food processing, pharmaceuticals, automotive air conditioning, supermarkets, hospitality, logistics, manufacturing, and industrial process cooling.
The right refrigerant depends on your equipment, operating conditions, cooling requirements, energy efficiency goals, and applicable regulations. Our technical team can help you identify the most suitable refrigerant based on your specific application and system compatibility. Write to us for assistance→ customercare@dewgas.com

R32 is primarily used in modern residential and commercial air conditioning systems. It offers excellent cooling performance, higher energy efficiency, and a lower Global Warming Potential (GWP) than many legacy refrigerants.
R410A is widely used in split air conditioners, VRF systems, heat pumps, and commercial HVAC equipment. It delivers efficient cooling performance in high-pressure systems.
R134a is commonly used in automotive air conditioning, domestic refrigeration, commercial refrigeration equipment, medical cooling systems, and industrial process cooling applications.
R404A is designed for low- and medium-temperature commercial refrigeration, including cold storage, supermarket refrigeration, refrigerated transport, and food processing applications.
Hydrofluoroolefin (HFO) refrigerants are next-generation refrigerants developed to significantly reduce Global Warming Potential while maintaining cooling performance. They play an important role in the global transition towards more sustainable cooling solutions.
Natural refrigerants are substances that occur naturally in the environment, such as carbon dioxide (CO₂), ammonia (R717), and hydrocarbons like propane (R290). They typically have very low GWP and are increasingly adopted for sustainable cooling applications.
The ideal refrigerant depends on the equipment design. Modern residential air conditioners commonly use R32 or R410A, while larger commercial systems may require other refrigerants recommended by the equipment manufacturer.
Commercial refrigeration applications commonly use refrigerants such as R404A, R407C, and other application-specific refrigerants depending on operating temperature and system design.
R134a remains widely used in many existing automotive air conditioning systems. Always use the refrigerant specified by your vehicle manufacturer, as newer vehicles may require different refrigerants.
Always follow the equipment manufacturer’s recommendations. Using an incompatible refrigerant can reduce performance, damage equipment, and void warranties. If you’re unsure, DewGas can help you identify the correct refrigerant for your system. Write to us for assistance→ customercare@dewgas.com
Yes. DewGas refrigerants are verified against AHRI 700 purity standards, ensuring they meet internationally recognised quality requirements for refrigerant composition and performance.
AHRI 700 specifies the acceptable purity levels, moisture limits, acidity, volatile impurities, and non-condensable gases for refrigerants. Compliance ensures consistent product quality and reliable system performance.
DewGas refrigerants are manufactured and tested to meet AHRI 700 purity requirements. Every batch undergoes comprehensive laboratory testing before dispatch to ensure high levels of purity and performance.
Each batch undergoes a five-point quality protocol including appearance inspection, acid-free verification, moisture analysis using Karl Fischer Coulometry, non-condensable gas screening through gas chromatography, and final purity certification before dispatch.
Simply scan the unique QR code printed on every DewGas cylinder. The system instantly displays product authenticity, batch information, filling details, and quality certification.
The QR code provides complete product traceability. It allows customers to verify authenticity, access batch details, review quality certificates, and confirm that the refrigerant has passed DewGas’s quality assurance process.
R32 has a lower Global Warming Potential (GWP), higher cooling efficiency, and contains a single-component refrigerant, making it easier to recycle. R410A is a blended refrigerant widely used in many existing HVAC systems. The appropriate choice depends on your equipment specifications.
R438A is commonly used as a retrofit alternative for R22 in many existing systems. However, compatibility depends on system condition, lubricant type, and manufacturer recommendations. Always consult a qualified HVAC technician before retrofitting.
Global Warming Potential (GWP) measures how much heat a refrigerant can trap in the atmosphere compared to carbon dioxide. Lower-GWP refrigerants help reduce environmental impact and support evolving climate regulations.
DewGas supplies refrigerants that are compatible with equipment designed for those specific refrigerants. Always verify compatibility with your equipment manufacturer or contact our technical team before replacing any refrigerant.
System efficiency depends on refrigerant quality, correct refrigerant charge, equipment maintenance, operating conditions, ambient temperature, component cleanliness, and proper installation practices.
Low-GWP refrigerants reduce greenhouse gas emissions while delivering effective cooling performance. They are becoming increasingly important as countries transition towards more environmentally responsible cooling solutions.
DewGas currently offers refrigerants that support today’s cooling requirements while investing in infrastructure designed for future lower-GWP refrigerants. As regulations evolve, our portfolio will continue expanding to support sustainable cooling technologies.
Yes. DewGas supports responsible refrigerant practices aligned with international environmental commitments, including the Montreal Protocol and India’s evolving refrigerant regulations.
The Kigali Amendment is a global agreement that requires countries to gradually reduce the use of high-GWP HFC refrigerants. India is implementing a phased transition, encouraging the adoption of lower-GWP alternatives over time.
India’s HFC phase-down follows the Kigali Amendment roadmap, with gradual reductions extending through 2047. The phased approach enables industries to transition responsibly while maintaining cooling infrastructure.
Governments worldwide are promoting refrigerants with lower environmental impact through stricter regulations, phasedown schedules, and sustainability initiatives. These changes are driving innovation in cooling technologies and refrigerant development.
Lower environmental impact, improved regulatory compliance, future-ready operations, better sustainability credentials, and long-term compatibility with evolving cooling technologies are among the key benefits.
Businesses can reduce environmental impact by selecting lower-GWP refrigerants, preventing leaks, maintaining equipment regularly, recovering refrigerants responsibly, and using certified, high-purity refrigerants from trusted suppliers.
