Compact Cooling Systems


1. Mini Compressor – Vapor Compression Refrigeration

RIGID put years of hard work into developing a revolutionary solution in vapor compression technology. The mini compressors this company designed are the result of this research. Their main advantage is that they manage to keep the noise at an impressively low level. Additionally, the system features low vibration, which contributes to lowering the noise.

Our team wanted to design a true miniature compressor. That’s why the products we design aren’t an inch bigger than absolutely necessary. We are proud of the fact that our laser cooling system features a compact size while maintaining impressive performance.

The compressor is a crucial part of our refrigerating system. That’s why the idea was to make this component as miniature as possible. After years of trying, we designed a revolutionary mini rotary compressor.

The biggest advantages of our rotary compressor include:

  • A compact size
  • Surprising lightweight
  • An efficient performance that compares with bigger units

We like to think of our compressors as “true power in small packaging.” This micro DC unit is perfect for portable and compact cooling machines. Although it already delivers consistent performance, our experts keep improving the compressor. The current fifth generation implements the sine wave drive board. We patented this approach as we believe it’s crucial to impressive performance.

What Are the Main Features of the Miniature BLDC Rotary Compressors?

At RIGID, customers have always been the top priority. That’s why we came up with a solution that will meet each client’s needs. Our BLDC compressors are available with different cooling capacities. It starts at 100W or 240Btu if you are looking for the smallest possible solution. If you prefer more power, our compressors are ready to deliver up to 550W, or 1,876BTu of strength.

You are in complete control of the device. Our cooling systems come with a drive board, which makes it easy to adjust the desired speed. The velocity can vary from 2,000RPM to 6,500RPM, and it all depends on your needs.

Our compressors can use 12V, 24V, or 48V DC. It’s also possible to convert it to AC by using the right kit. This incredible versatility made this portable cooling system extremely popular. It’s possible to use it for various applications. That includes a laser hair removal cooling system, as well as other medical, military, and similar purposes. You can put the device on the countertop as it takes a minimum footprint on it. It’s also excellent to use on the go. The compact size contributes to impressive portability.

RIGID mini rotary compressor is extremely efficient, which is possible because it uses the R134A refrigerant. The device is also compatible with R290A for those who prefer that option. The total weight of the unit doesn’t exceed 720 grams, which is around 1.5 pounds. Our experts implemented a one-cylinder setup under standard ASHRAE requirements.

And here is the best part – the total energy consumption is surprisingly low. You’ll find that it utilizes 40% less energy than other systems. While we are discussing that, let’s mention the noise reduction is around 5dB(A). That’s an impressive advancement compared to the previously used system. It ensures the compressor is quiet and efficient, which means its activity won’t disrupt others.


Can You Use the Compressor in Indoor or Outdoor Conditions?

The primary purpose of RIGID’s rotary compressors is indoor use. That could be in vehicles for transport or other indoor settings. The reason for this is that optimal lubrication requires an ambient temperature of at least 5C.

However, if you require outdoor use, you should be aware that RIGID designed a T-tropical series of its units. These mini compressors can operate at temperatures up to 52C. That makes them the perfect cooling solution in outdoor environments. You can use it for automotive purposes to reduce and maintain optimal temperatures.

The best part is that RIGID’s compressors can deliver excellent performance and optimal thermal management while maintaining impressive lightness. The compressor that weighs 1.5 pounds can have a 30% better performance than a unit that weighs six times as much.


2. Micro DC Aircon – Air Circulating Systems

The idea of a micro DC air circulating system is simple. It removes the heat from the device to cool it down. The hot air that gets removed from the product circulates through our unit. Thanks to the circulation, it becomes cooler when it returns to the device. That ensures the overall temperature of your product goes down. It’s the perfect option that works well as a CO2 laser cooling system and has many other applications.

Here is the overview of the main characteristics offered by the micro DC aircon systems:

  • RIGID ensures that you can pick the desired voltage option from 12V, 24V, and 48V adjustments. The DC voltage ensures you utilize minimum energy without requiring converters.
  • The weight varies from around ten to twelve pounds. This is a small difference between the least and most powerful options. It’s worth noting that even the settings with the fewest wattage offer efficient performance.
  • The size of our micro DC aircon is 350x260x180 millimeters. Yes, you are not wrong; that means the entire unit is incredibly small!

All variations use the R134A coolant, and they operate with an airflow rate of 28.3CFM at the cold air outlet. You can adjust the desired heat transfer rate, and the unit will exceed all expectations when it comes to managing the target temperature.

You’ll be more than happy with our liquid circulation systems. Once again, our idea was to design a compact product for various applications. That includes a laser cutter cooling system but also other applications across different industries.


What’s the Working Process of a Liquid Circulating System?

The idea is simple, and it all starts with an intuitive design. The fluid goes into a single pipe. Once it reaches that tube, our mini compressor is in charge of cooling the liquid. After the compressor lowers the temperature of the fluid, it goes to the other pipe. That pipe helps to return it to the device.

The system requires an external pump but managed to keep a compact size. It also has an impressive capacity and surprising efficiency. It can lower the heat level significantly while maintaining a consistent temperature. It’s perfect for active thermal management, where you need to keep the heat at the same level for a long time.

It’s possible to use the device as part of your chilling system. Alternatively, it’s even possible to integrate RIGID’s liquid circulation system into your setup. That means they can become a part of your product. The increase in weight and size will be only minimal, and the cooling benefits will exceed all your expectations.

Here is a quick overview of the available liquid chillers:

  • Plate liquid chillers. These use a plate and frame heat exchanger.
  • Coaxial liquid chiller. It uses stainless steel coaxial exchanger when transferring heat between fluids.
  • Stainless steel liquid cooler. This is an excellent option for portable and compact chilling. You often find it in a laser diode cooling system and many other applications.
