By Type, Glycols Dominate the Secondary Refrigerants Market While CO2 Brines Emerge as the Fastest-Growing Type Segment

The Glycols segment dominated the Secondary Refrigerants Market in 2025 owing to its widespread use, low cost, and proven freeze-protection performance across commercial refrigeration, HVAC, and industrial cooling applications. Ethylene and propylene glycol-based fluids continue benefiting from established supply chains, broad chemical compatibility with existing piping and heat exchanger materials, and straightforward maintenance requirements that make them the default choice for operators retrofitting direct-expansion systems into indirect loop architectures. Continued availability from major chemical producers and well-understood handling protocols further reinforced glycols' leading revenue contribution within the overall type mix throughout the forecast period.

CO2 Brines has emerged as the leading growth contributor in the Secondary Refrigerants Market owing to increasing demand for natural refrigerants with low global warming potential among both regulations and consumers for the retrofit of refrigeration applications in supermarkets and industry. Transcritical CO2 refrigeration systems and increasing implementation of CO2 brines in these systems especially in European and increasingly in North American supermarkets is continuously driving the demand. Increasing stability and corrosion resistance of CO2 brine formulation is likely to continue supporting the high growth of this segment.

By Application, Commercial Refrigeration Leads the Secondary Refrigerants Market While Heat Pumps Record the Fastest Growth

The Commercial Refrigeration segment dominated the Secondary Refrigerants Market in 2025, anchored by widespread indirect refrigeration adoption across supermarkets, convenience stores, and cold storage warehouses seeking to minimize primary refrigerant charge and leakage liability. The increased investments by supermarket chains in centralized indirect refrigeration racks, which utilize secondary fluids for the distribution of the cooling effect through many cases from one compressor room, enhanced the market share of this segment in terms of revenue generation. The presence of the service network in matured markets for retrofits and servicing also contributed to its market leadership.

The Heat Pumps segment is the fastest growing within the Secondary Refrigerants Market, driven by accelerating residential and district heating electrification alongside growing government incentive programs supporting heat pump installation as a fossil fuel heating alternative. Secondary fluids will ensure that thermal energy can be transferred in the heat pumps by making use of building distribution systems while using very little amount of refrigerant inside the building. The favorable policies regarding building electrification expected from Europe and North America would continue this trend during the forecasted period.

By End-Use Industry, Food & Beverage Dominates the Secondary Refrigerants Market While Chemical & Pharmaceutical Emerges as the Fastest-Growing End-Use Segment

The Food & Beverage segment dominated the Secondary Refrigerants Market in 2025, resulting from the dependence of the industry on indirect refrigeration within processing plants, cold storage warehouses, and retail display systems, ensuring stringent product safety and quality requirements. The further development of cold chain logistics in both developed and developing countries, along with stricter food safety legislation, increased the revenues generated by this segment of the end-user market. The presence of well-established ties between fluid manufacturers and food industry refrigeration installers helped in maintaining its market dominance.

The Chemical & Pharmaceutical segment is the fastest growing within the Secondary Refrigerants Market, propelled by expanding biologics and vaccine cold storage capacity requiring precise, stable temperature control across manufacturing and distribution networks. Growing pharmaceutical cold chain investment, particularly for temperature-sensitive biologic drugs, continues driving demand for reliable, non-corrosive secondary fluids capable of maintaining tight temperature tolerances. Rising global biologics manufacturing capacity is expected to sustain this segment's above-average growth trajectory through the forecast period.

Market Dynamics

Growth Drivers: Tightening Refrigerant Regulations and Expanding Cold Chain Infrastructure

The industry is driven by tightening regulations on high-global-warming-potential primary refrigerants, rising adoption of glycol and salt brine heat transfer fluids, growing deployment of CO2 brines as a low-GWP alternative, and continued adoption across commercial refrigeration, industrial refrigeration, heat pump, and air conditioning applications. As F-Gas Regulation and Kigali Amendment phasedown schedules tighten globally, the need for indirect refrigeration architectures that minimize primary refrigerant charge keeps driving sustained operator investment in secondary refrigerant fluids.

Expanding cold chain logistics infrastructure continues reinforcing this driver, as food processors, pharmaceutical manufacturers, and retail grocery chains increasingly invest in temperature-controlled storage and distribution capacity across both developed and emerging economies. Continued advancement of CO2 brine formulation stability and heat pump electrification incentive programs further supports this driver, and that combination of regulatory pressure and infrastructure expansion is exactly what keeps demand climbing at a steady, sustained pace.

Restraints: Volatile Feedstock Pricing and Retrofit Capital Costs

Volatile pricing of key petrochemical feedstocks used in glycol production continues posing a genuine restraint on stable market-wide margins, particularly for smaller fluid formulators without the purchasing scale that major chemical producers can leverage. That cost volatility has kept pricing pressure a persistent challenge across the competitive landscape, particularly during periods of broader ethylene and propylene glycol feedstock price fluctuation.

The substantial capital investment required to retrofit existing direct-expansion refrigeration systems into indirect secondary loop architectures continues posing a further restraint, as smaller commercial refrigeration operators often lack the capital budgets that large grocery and cold storage chains can commit. That cost profile has kept large-scale retrofit activity concentrated among a comparatively small number of well-resourced, often multinational retail and logistics operators.

Opportunities: CO2 Brine Innovation and Heat Pump Electrification Expansion

Advancement of CO2 brine formulation technology represents a genuinely significant opportunity, as this emerging fluid category promises substantially lower global-warming-potential relative to conventional glycol-based products. Fluid formulators positioned early in commercially viable CO2 brine solutions stand to capture meaningful share as transcritical CO2 refrigeration adoption continues expanding across supermarket and industrial cooling applications.

Expansion into heat pump and building electrification applications offers a second substantial opportunity, as governments increasingly incentivize heat pump installation as a fossil fuel heating alternative across residential and district heating networks. Fluid manufacturers with established and commercially-proven formulas for thermal conductivity will benefit from an increasing level of policy support aimed at building electrification through the forecast period.
