Pure Thermal provides glycol chiller systems intended for sites that demand stable cooling for production, HVAC, and process use. These systems deliver 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 carefully balanced mixture of water and glycol to circulate cooling capacity through a system. The addition of glycol reduces 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 remains constant throughout the year. 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 follow 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 stable 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 –30°C, depending on the application.
Use of Natural Refrigerants
Pure Thermal glycol chillers use refrigerants with reduced global warming potential or natural refrigerants. This helps lower environmental impact compared to traditional cooling systems that rely on synthetic refrigerants with higher GWP values.
Natural refrigerant options such as read more hydrocarbon or CO2 systems also remove concerns around F-Gas compliance. This supports facilities against future refrigerant cost increases or regulatory changes linked to phased reductions in HFC refrigerants.
For businesses planning future cooling investment, this offers a practical way to manage compliance requirements without needing major system changes at a later stage.
Integration with Existing Plant and Systems
Pure Thermal glycol chillers can connect to existing cooling plant. Many systems interface with 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 upgrade 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.
Process Cooling in Manufacturing Environments
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 removes excess heat and maintains equipment within a safe and stable 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 thirty kilowatts 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.
Typical Applications for Glycol Chillers
- Food and drink production
- Manufacturing and production plants
- Pharmaceutical facilities
- Commercial HVAC installations
- Process cooling circuits
- Temperature-controlled storage facilities
In each case, the objective remains the same: the system must deliver reliable temperature control and protect equipment or products from heat-related damage.
Project and Engineering Support
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.
This structured approach 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 long-term temperature stability while supporting energy efficiency across the wider site.
