CIMG-4500 : Compact liquid cooler 400W (0.54HP) with four pumps and temperature regulators | JoinTech (KegLand KL47364)

The CIMG-4500 is an efficient glycol cooler for two up to fourt fermenters that has a fantastic cooling performance. It is compact, quiet and ideal for the home environment. It is powerful enough to independent cool up to four well-insulated fermenters up to 40-60L size or up to two fermenters up to 80-120L size. It has a cooling power of about 400 Watts (0.54 HP), so it is suitable for shock cooling even at high ambient temperatures. The new model is equipped with the “JoinTech Dry Break” fittings for quick connection the cooler with the chilled water-glycol hoses.

Unlike other cooling units, this chiller comes with 4 integrated pumps and temperature controllers. This allows you to independently cool from two up to four fermenters simultaneously at different temperatures.
Set the temperature on the main tank to -4C, then (after adding 20-30% glycol) and on the other side of the CIMG-4500 set the other four temperatures to your ideal fermentation temperatures. No additional wiring and accessory is required (only hoses for connection of the chiller with the tanks). The pumps are included in the delivery and are already connected, ready to use.

• Power consumption: 210 Watts
• Glycol tank: 30L
• Maximum flow rate of each pump: 600 l/h
• Maximum head of each pump: 5 m
• Glycol outlets / inlets : 4 pairs : JoinTech Dry Break 1/2″ (male)
• 4 wheels
• Dimensions: 410mm x 410mm x 660mm (L x W x H)
• Weight : 35 kg

For operation at temperatures below freezing, a suitable mixture of water and propylene glycol must be used. The manufacturer recommends a glycol concentration of approximately 20%, which allows the coolant temperature to be set to approximately −4 °C.

Filling the reservoir with water and glycol

The CIMF-4500 chiller can be operated with either just water in the reservoir or both water and glycol to reduce the freezing point of water.

IMPORTANT: If you are only using water in the reservoir and not glycol then never do set the temperature of the reservoir below 2°C.

Fill the reservoir to a total of 20L with water if the reservoir is set at 2°C or an appropriate Concentration of glycol solution if dropping the reservoir below 2°C according to the table below.
Ensure the cooling coils are submerged.

The amount of glycol required to be added to the reservoir depends on the desired set temperature of the reservoir which is dependent on a number of factors including heat ingress into the entire system, insulation of the glycol lines, ambient temperature, the number of kegs being cooled and the temperature of the kegs.

Use the table below to determine what percentage of glycol you require.
