Pure Thermal supplies glycol chillers designed for sites that demand stable cooling for manufacturing, HVAC, and process applications. These systems support reliable thermal control across a wide range of commercial and industrial environments where water alone cannot provide sufficient freeze protection or reliable low-temperature operation.
A glycol chiller uses a controlled mixture of water and glycol to transfer cooling energy through a system. The addition of glycol lowers the freezing point of the circulating fluid, allowing the system to operate at reduced temperatures without the risk of ice formation within pipework or heat exchangers.
This approach works effectively in applications where cooling demand is continuous year-round. Manufacturing processes, food production sites, and large commercial facilities often rely on glycol chillers to maintain equipment or products within a required temperature range.
How Glycol Chillers Work
Glycol chillers operate using the same core refrigeration cycle used in other chilled water systems. The unit removes thermal energy from a process or space and transfers it through a heat exchanger, removing unwanted heat from the system to required operating conditions.
The glycol solution circulates continuously between the chiller and the connected equipment. As it moves through the system, it captures heat before returning to the chiller for cooling again. This continuous cycle ensures steady cooling output, which is essential for production lines and temperature-sensitive environments.
Because the glycol mixture can operate at sub-zero temperatures without freezing, these systems enable applications where chilled water alone would not perform safely. In some cases, Pure Thermal systems can operate with leaving water or glycol temperatures as low as minus thirty degrees Celsius, depending on the application.
Low GWP and Natural Refrigerant Options
Pure Thermal glycol chillers use low global warming potential (GWP) refrigerants or natural refrigerants. This reduces environmental impact compared to traditional cooling systems that rely on synthetic refrigerants with higher GWP values.
Natural refrigerant options such as hydrocarbon or here CO2 systems also reduce the need for F-Gas compliance. This helps protect facilities against future refrigerant cost increases or regulatory changes linked to phased reductions in HFC refrigerants.
For businesses planning long-term cooling infrastructure, this offers a measured way to manage compliance requirements without needing major system changes at a later stage.
Integration with Existing Cooling Infrastructure
Pure Thermal glycol chillers can integrate with existing cooling plant. Many systems link to air handling units, fan coils, or production cooling circuits without the need for extensive site modifications.
This makes them suitable for retrofit projects where ageing chillers require replacement. Operators can modernise their cooling equipment while maintaining current distribution systems such as pipework and control infrastructure.
Where simultaneous heating and cooling demand exists, certain systems can also provide heat recovery outputs. Waste heat from the cooling cycle can be used elsewhere on site, for example for domestic hot water or space heating. In some applications, recovered heat can exceed the original cooling output under appropriate operating conditions.
Temperature Control for Production and Process Use
Cooling systems within manufacturing environments often operate continuously throughout the year. Equipment such as processing machinery, hydraulic systems, or packaging lines produce heat as part of normal use.
A glycol chiller extracts generated heat and maintains equipment within a controlled working temperature range. This helps prevent overheating and supports consistent production output. In facilities where simultaneous heating demand exists, recovered waste heat can also reduce reliance on separate heating plant.
Pure Thermal chillers are available with capacities from 30 kW up to three megawatts, depending on project requirements. These systems support both new-build projects and upgrades to existing installations where cooling demand has changed.
Suitable Applications
- Food and drink production
- Industrial manufacturing facilities
- Pharmaceutical facilities
- Large-scale HVAC systems
- Dedicated process cooling systems
- Temperature-controlled storage facilities
In each case, the objective remains the same: the system must maintain stable temperatures and protect equipment or products from heat-related damage.
Engineering Support from Pure Thermal
Pure Thermal provides engineering support throughout each project stage, including application review, equipment selection, system commissioning, and ongoing maintenance assistance.
An in-house applications engineering team works with system designers and contractors to ensure that the selected glycol chiller matches site demand and operating conditions.
Such planning helps reduce performance issues after installation, as system design takes account of load demand, operating temperatures, and integration with other plant already in use.
For organisations that require dependable process cooling, a correctly specified glycol chiller provides reliable long-term performance while supporting energy efficiency across the wider site.
