However, high initial capital costs for system upgrades pose a challenge for new entrants and small-scale players, potentially slowing innovation and adoption rates. Despite this, the market is ripe with opportunity, thanks to technological advancements, rising demand in emerging economies, and regulatory support for low-GWP alternatives.

End-Use Insights

• Heat Pumps led the market in 2024, contributing 16.2% of total revenue, due to their dual heating and cooling capabilities, which are essential for both residential and commercial settings.

• Air Conditioning Systems continue to be a major application area, benefiting from the use of glycol- or water-based secondary refrigerants to optimize performance, reduce energy costs, and minimize emissions.

• Efficiency and Environmental Safety Propel Adoption of Secondary Refrigerants

  Secondary refrigerants function as intermediates in the cooling cycle, transferring heat from the target area to the primary refrigerant, thereby minimizing the direct use of high-GWP refrigerants. Their core advantages—non-toxicity, non-corrosiveness, incombustibility, and high thermal capacity—make them suitable for safe and efficient cooling, especially in low- and high-temperature applications.

  Common secondary refrigerants include propylene glycol, calcium chloride brine, carbon dioxide, and specialty oils, widely used in industrial refrigeration, heat pumps, commercial cooling, and HVAC systems.
