RAPT Bluetooth Glycol Chiller (400W)

A compact, powerful compressor glycol chiller with Bluetooth control through the free RAPT app. It packs 400 watts of cooling into a small footprint and can easily take the glycol bath below zero, down to about -10°C, for crash chilling fermenters or running a flooded font.

Features

• Compact design with 400 watts of cooling power
• Large, easy-to-read display
• Bluetooth control via the RAPT app
• Pairs with the RAPT Glycol Controller (sold separately)
• Reaches sub-zero temperatures easily (about -10°C)
• Dry-break JoinTech male fittings included

How it works

You set the temperature of the glycol bath on the display. A 12V glycol pump pressurises both JoinTech outputs. If you’re cooling just one fermenter, you can plug the pump’s power supply into a temperature controller so the pump cycles on and off to cool the fermenter.

The recommended setup is to add a RAPT Glycol Controller between the chiller and your fermenter. It uses a built-in pinch valve to adjust glycol flow to the fermenter, and has an AC outlet to run a heater such as a Warming Wizard or heat belt, so it handles both heating and cooling. It also acts as a Bluetooth repeater for a RAPT Pill (temperature and gravity) and shows what’s happening in your fermenter at a glance.

True compressor cooling

Unlike cheaper thermoelectric coolers, this is a true compressor chiller. You can crash chill a fermenter easily even on very hot days, while using far less energy. Compressors are several times more energy efficient than thermoelectric units.

Great for flooded fonts

Its small size, price and ability to run the pump continuously make it an easy way to chill a glycol flooded font. The pump runs from a standard 10A socket, so you can put it on a smart plug and have your font icy cold in time for serving.

Fittings and hoses

The chiller comes with male JoinTech fittings. To connect it you may also need JoinTech female connectors with auto shut-off (KL41102), JoinTech male x 1/2″ BSPT fittings (KL41096), and insulated glycol hose in red for return (KL40587) and blue for outlet (KL40570).
