Icemaster G20 - Glycol Chiller

Icemaster G20 Glycol Chiller – Precision Temperature Control 

The Icemaster G20 Glycol Chiller is an advanced and compact solution for maintaining precise temperature control throughout the brewing process. Designed for home brewers and small-scale breweries, it combines robust performance, energy efficiency, and versatility to meet the most demanding brewing requirements. The glycol chiller is an indispensable tool for professional and home brewers alike, ensuring optimal conditions for every stage of brewing.

This glycol chiller features 500 watts (0.67 HP) of cooling power, rated at an ambient temperature of 22°C, ensuring reliable operation even in warmer conditions. It is powerful enough to chill well-insulated fermenters up to 200L in size or multiple smaller fermenters.
Using environmentally friendly R600a isobutane refrigerant, the Icemaster G20 Glycol Chiller offers exceptional cooling efficiency while maintaining eco-conscious standards.

Equipped with a 16.42-litre tank, the chiller works optimally with a glycol-water mixture (20-30% glycol concentration) to achieve a freezing point of approximately -8°C. This ensures the perfect balance of heat transfer efficiency and freeze protection, making the glycol chiller ideal for a wide range of brewing needs, from chilling wort to maintaining fermentation temperatures.

Key Features:

• Dual Temperature Control: Equipped with two integrated pumps and dual temperature controllers, the Icemaster G20 Glycol Chiller allows independent cooling of two fermenters simultaneously, each at different temperatures. This flexibility is particularly beneficial for managing multiple fermentation processes concurrently. 
• 
  Environmentally Friendly Refrigerant: Utilizes R600a isobutane, an eco-friendly refrigerant that offers efficient cooling performance. 
• 
  Compact Design: With dimensions of 510 mm (L) x 300 mm (W) x 460 mm (H), the glycol chiller is designed to fit comfortably in various brewing setups without occupying excessive space. 
• 
  Integrated Pumps: Comes with two integrated pumps, each capable of a maximum head of 5 meters and a maximum flow rate of 600 liters per hour, facilitating efficient circulation of the glycol solution. 

Integrated Pumps for Dual Cooling Circuits

The Icemaster G20 Glycol Chiller includes two integrated pumps, each with independent temperature controllers, enabling you to cool two separate fermenters simultaneously at different temperatures. Each pump boasts a maximum head of 5 metres and a maximum flow rate of 600 litres per hour, ensuring smooth glycol circulation even in complex setups. Whether you're fermenting lagers that demand low temperatures or ales that require stability, the glycol chiller works seamlessly with fermentation vessels such as the Conicus Pro or Kegmenter.

Effortless Wort Chilling and Fermentation Control

For efficient wort chilling, the Icemaster G20 Glycol Chiller can be paired with plate or counterflow wort chillers to rapidly bring hot wort down to yeast-pitching temperatures, preserving flavour and quality. During fermentation, its precise temperature controls allow you to manage diverse brewing profiles, ensuring consistent results for every batch.

Cool Fermenters, Conicus Pro, and Kegmenter

Whether you're fermenting lagers that require low temperatures or ales that need stable fermentation conditions, the Icemaster G20 Glycol Chiller is versatile enough to meet your needs. Compatible with a wide range of fermentation vessels, including the Conicus Pro and Kegmenter, it provides the flexibility to achieve consistent results, batch after batch.

Compressor Cooling Technology

At its core, the Icemaster G20 Glycol Chiller features a robust compressor-based cooling system powered by a 155-watt motor. This system is engineered for energy efficiency, offering professional-grade cooling with minimal power consumption. The compact and durable design ensures the glycol chiller fits comfortably into various brewing environments, with dimensions of 510 mm (L) x 300 mm (W) x 460 mm (H).

Crash Cooling with the Icemaster G20 Glycol Chiller

Crash cooling is a vital step in brewing, used to rapidly lower the temperature of your beer after fermentation. The Icemaster G20 Glycol Chiller excels in this process by quickly chilling your fermenter to near-freezing temperatures. This helps to:

• Clarify the Beer: Cold temperatures cause yeast and proteins to flocculate and settle, resulting in a cleaner, brighter beer.
• Improve Shelf Life: Crash cooling reduces the risk of unwanted fermentation or spoilage during storage.
• Streamline Filtration: Removing sediment during crash cooling makes the beer easier to filter or transfer.

Installation Requirements

For optimal performance and longevity, adhere to the following installation guidelines:

• Ventilation: Ensure at least 100 mm of clearance around all air vents for proper airflow and heat dissipation.
• Placement: Position the glycol chiller on a stable, level surface away from direct sunlight and excessive moisture.
• Electrical Connection: Use a reliable power supply (220-240V, 50Hz) to avoid interruptions.
• Glycol Mixture: Always use a 20-30% glycol-water mixture for efficient and safe operation.

Glycol Temperature Controller Instructions

The digital temperature controllers make it easy to manage your brewing environment:

1. Set Desired Temperature: Input the required temperature for each cooling circuit using the digital interface.
2. Adjust Glycol Temperature: Maintain the glycol mixture at -5°C to -8°C to achieve optimal heat transfer without freezing.
3. Monitor and Update: Periodically check the system and adjust settings as necessary for different brewing stages or vessel requirements.

Maintenance Tips

For best performance, it is recommended to use a glycol-water mixture with a concentration of 20-30% glycol, achieving a freezing point of approximately -8°C. This mixture ensures efficient heat transfer and prevents freezing within the system.

Using an old mixture can damage the pumps and will void the warranty.

• Regularly clean the radiator and air vents to remove dust and ensure efficient cooling.
• Replace the glycol-water solution annually to maintain optimal performance and prevent degradation.
• Inspect tubing connections to ensure a secure, leak-free setup.

The Icemaster G20 Glycol Chiller is an essential tool for brewers who value precision, consistency, and quality. From rapidly chilling wort to maintaining perfect fermentation conditions, this glycol chiller supports every step of your brewing journey, delivering reliable and professional-grade performance.
