When purchasing a chiller, consider reliable, industry-recognized brands. Some of the top players include Conair, Frigel, Advantage, Thermal Care, AEC, Temptek, Top Chiller, and Drycool Systems just to name a few.
Each brand offers unique solutions tailored for different needs, from compact portable chillers to larger central cooling systems.
Here are some helpful hints to keep in mind when assessing your needs.
1. Cooling Capacity - Match the chiller’s capacity to your process requirements. Choose a slightly higher capacity than your cooling load to ensure efficiency.Consider the heat load from equipment size, throughput, and material type.
2. Temperature Control - Opt for chillers with precise temperature control, typically within ±0.5°C, to maintain consistent molding conditions.Verify the temperature range meets your needs (usually 1°C to 7°C or 34°F to 45°F).
5. Cooling System Type - Air-Cooled Chillers are suited for smaller facilities due to simpler installation requirements. Water-Cooled Chillers provide a higher cooling capacity and are ideal for larger installations.
6. Space Requirements - Evaluate available space. Portable chillers are compact and mobile, while central chillers serve large-scale operations.
Pro Tip: Most chillers previously relied on HFC refrigerants like R410A, introduced in the 1990s for their near-zero ozone depletion potential (ODP). However, HFCs are now being phased out due to their high Global Warming Potential (GWP). For example, R410A contributes 1,890 times more to global warming than carbon dioxide.
Key Regulations and Compliance
- United States: From January 1, 2024, 12 states require new chillers to use low-GWP refrigerants (GWP of 700 or less). Nationwide regulations may be implemented by 2026.
- Canada: From January 1, 2025, all manufactured or installed chillers must use low-GWP refrigerants.
- Existing chillers using high-GWP refrigerants are “grandfathered” and can remain operational throughout their lifespan but cannot be retrofitted to low-GWP refrigerants.
Leading manufacturers, such as Conair, are transitioning to low-GWP refrigerants by redesigning their chillers. Modern Conair chillers are compatible with refrigerants such as R454B while maintaining the flexibility to use R410A in approved regions.
Why Retrofitting Isn’t an Option
Due to differences in thermodynamic properties and operating pressures, retrofitting older chillers to low-GWP refrigerants is neither safe nor feasible. Manufacturers recommend investing in new units designed for compliance and efficiency.
Invest in Future-Ready Chillers
Selecting the right chiller for your plastics operation requires a combination of capacity planning, energy efficiency evaluation, and adherence to regulatory standards. Explore options from trusted brands like Conair, Frigel, and Thermal Care to secure reliable cooling solutions for your facility. By transitioning to low-GWP refrigerant systems now, your operations will stay compliant and align with sustainable practices.
