Boyard specializes in providing cutting-edge compressor and HVAC system solutions, including the versatile mini chiller units. These mini chillers are specifically designed to meet cooling requirements in constrained spaces, catering to diverse applications such as medical devices, laboratory equipment, and heat-generating electronics/ machines/ batteries.

The primary function of a mini chiller is to effectively dissipate heat and maintain a constant low temperature. This is achieved through the circulation of liquid coolant, employing methods like direct evaporation or expansion to extract heat from surfaces or through air cooling. By ensuring precise temperature control, mini chillers safeguard against overheating and optimize system performance. In addition to conventional AC power, these systems are available in DC power variants such as DC 12V, DC 24V, or DC 48V, widening their compatibility with different setups.

Q: Why miniature chillers are often designed to be powered by DC (direct current) power sources? Here are several reasons:

A: 1. Portability: DC power sources, such as batteries or solar panels, provide portability and flexibility. Miniature chillers powered by DC can be used in remote locations, outdoor settings, or on-the-go applications where AC power sources may not be readily available.

2. Efficiency: DC-powered chillers can be more energy-efficient compared to AC-powered chillers, especially when using high-efficiency DC compressors and motors. This can be beneficial for applications where energy conservation is a priority, like driven by lithium battery.

3. Compatibility: Many electronic devices and small appliances operate on DC power. Using DC power for miniature chillers ensures compatibility with existing power sources in electronics or small equipment without the need for additional converters or adapters. Such us laser application, laser system usually are 48V

4. Safety: DC power can be safer for certain applications, especially in environments where electrical safety is a concern.
