24V Liquid Cooler: Compact and Portable Recirculating Water-Chilled Unit.

The 24V liquid cooler is designed for indoor and outdoor cooling applications. It adopts miniature vapor compression technologies, by using a mini 24V compressor to cool liquid.

The 24V cooler has the smallest footprint and the built-in pump circulates the cooled liquid to cool the target heat parts and components. Then flow back to the reservoir after the heat exchange. Once the circulating liquid reaches the set point temperature, the 24V liquid cooler will intelligently control the cooling capacity to keep the target temperature. The water cooler provides 100W to 400W cooling capacity (data changes according to different working conditions), is powered by 24V DC battery, and temperature control ranges -5℃ to 30℃ (23℉ to 86℉), and accuracy +/-0.1℃. Compressor speed, temperature, and reservoir level can be monitored, and a USB port allows control and logging of most features. User can pre-cool liquid in the internal reservoir and get the target temperature as quickly as he expects.

As a pioneer in the miniature cooling industry, RIGID has developed many innovative compact cooling systems for various industries and applications. The 24V liquid cooler is the smallest, lightest, industrial-class reliability and most energy-efficient solution that applies to industries & applications like Aerospace & Defense, Laser & Electronics, Digital Printing, Food & Beverage, Mobile Imaging, 3D printing, Plastics, Photonics, Research, and Semi-Conductor, etc. RIGID 24V Liquid Cooler is an iceless cooling system, No need ice, no maintenance. with its compact size, minimal weight, and industrial-class reliability.  it is an essential liquid chiller for various heating & cooling applications.

1. How does the Liquid Chiller LC3220E-H work?

A liquid chiller is a product that secures cooling by using liquid circulation or convection. The liquid serves as a heat conductor and removes the heat from devices and components. That is how it manages to cool them down and keep them cool.

The Liquid Chiller LC3220E-H keeps your device cool and focused in extreme temperatures by pumping liquid (like distilled water, propylene glycol, or coolant formula) through devices and equipment. Powered by a rotary micro-compressor, NO Ice! NO chemical cold pad!

2. What applications Liquid Chiller LC3220E-H apply to?
  • Laser devices
  • Battery packs
  • Medical equipment
  • Photonics effective cooling
  • Small chilled water systems
  • Electronics cooling systems
  • Electric vehicle charging stations
  • Semiconductor test industry application
  • Besides, you also can combine RIGID Liquid Chiller LC3220E-H with a cooling shirt or vest, which is a compact chiller for human body cooling. Chiller LC3220E-H circulates water flowing through the suit, helping to take away the heat released by the human body.
  • LC3220E-H works as a liquid chiller to cool the circulating water and provide continuous cooling water for the human body cooling.
3. How is Chiller LC3220E-H able to generate marvellous power for its size?

The Chiller LC3220E-H has one of the highest power-to-weight ratio rotary micro-compressor in the world. Capable of producing as much cooling power as a compressor 5x its size – this is the heartbeat of our cooling system

4. How is the Liquid Chiller LC3220E-H different from other cooling systems?

It is dual functions of Heating and Cooling. Easy & Swift. The Chiller LC3220E-H requires no ice! It adopts the world’s smallest variable speed refrigerated compressor to operate. Small body, Power engine. Driven by a dc power supply (24V), it runs on a continuous cooling cycle, therefore will cool
as long as the system is turned on.
It’s extremely lightweight, and compact, and has a fluid flow rate of 5 liters per minute at 16psi. The rotary micro-compressor inside is as strong as other systems 5 times its size.
It requires zero maintenance and allows you to set and change your temperature to your

5. What does the Coolant Formula consist of?

Usually, distilled water is good if your target liquid temperature is above 4C degree.
If you want a much lower liquid temperature, you have to consider Coolant Formula to avoid frostings, like propylene glycol or water mixtures.

6. What’s the temperature range of Liquid Chiller LC3220E-H?

Factory setting is 4ºC ~45ºC (39ºF ~113ºF). We can customize according to the customer’s special demands.

7. What’s the best temperature for racing driver body cooling?

The recommended temperature setting is 13ºC (55º F). We recommend this mid-range temperature because studies show that temperatures below 55º can shock the capillaries just below the surface of the skin and cause them to close, actually causing your body to hold heat. 55º – 60º around the torso and vital regions of the body is most effective, cooling your body from the core.


8. How long does the Chiller LC3220E-H operate before needing to be refilled?

The Chiller LC3220E-H functions on a continuous cycle. Your device’s operating frequency and how often you use the system effects how often you need to refill the reservoir. Chiller LC3220E-H only requires one to one coolant formula for distilled water mixture, so we recommend topping off before every use to prevent the system from running dry.

9. What are the dimensions and weight of Liquid Chiller LC3220E-H?

External dimension: 339x208x235 mm (13×8.2×9.2 inch)
Net weighs: 5kgs/11lbs

10. How can I control the temperature of Liquid Chiller LC3220E-H?

A digital display in front of the chiller communicates the current temperature.

11. Can the Liquid Chiller LC3220E-H cool more than one device?

Depending on the ambient temperature at the time, your system and install. RIGID also provides customized service and design.

12. What are the power requirements to power a Chiller LC3220E-H?

While power draw can spike to 12 amps max, depending on your surrounding temperature, average draw is 4-5 amps. The system runs on 24 volts AC adapter. Tested in maximum compressor speed at 6000rpm, our system uses around 550 watts at maximum. We highly recommend adding an inline fuse within 6 inches from the power supply, inlinewith fans and ducting to prevent from heat soak and high amp draw. Forcing ambient air intake to the chiller can significantly affect the draw rate.

13. How do I install the Chiller LC3220E-H?

The RIGID Compact Cooler requires a 24V 10 amp or greater power supply. We recommend you install to accessory and add an inline fuse within 6 inches of the power supply.

Note* the red wire is positive, the black is ground. Mount the base plate. The mounting location should be in the coolest, most ventilated portion of the system. Cooler air will boost efficiency and reduce current draw, therefore, mount the system where the intake is facing away from the transmission tunnel and exhaust. Do not mount the system over the transmission tunnel or exhaust.

We recommend you use 1″-1.5″ spacers between the cooler and the floor pan to allow cooler air to circulate under the system to prevent overheating. In some devices, a duct and blower may be necessary to source cooler air. Operating temperatures should not exceed 60º C / 140º F without additional fans or blowers.

If the temperature exceeds 140º F, the system will shut off to prevent overheating. Consider the shorter the length of the cooling hose, the more efficient the hose will be. Hoses can be cut to fit and shrink-wrapped for a clean, finished look. Visit our website for more videos and tips. WWW.RIGIDHVAC.COM

14. What are the maintenance requirements for the Liquid Chiller LC3220E-H?

There are zero maintenance requirements for Chiller LC3220E-H. We only suggest that you top the Coolant Formula off before every use to prevent it from ever running the system dry.
