Miniature Chiller Unit

Miniature Chiller Unit

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.

Miniature cooling units boast several design specialties, such as compact dimensions, efficient heat transfer capabilities, low operational noise, and superior temperature control. Moreover, these energy-efficient units seamlessly integrate into various systems and can be customized with adjustable temperature settings, corrosion-resistant materials, and advanced remote monitoring functionalities.

As a trusted provider, Boyard offers a comprehensive range of mini chiller solutions suitable for diverse applications, including medical devices, biochemical equipment, laser machines, laser projectors, battery thermal management, and personal cooling needs. Our experienced engineers collaborate closely with customers, validating cooling capacity requirements and simulating airflow and direct cooling heat transfer within the system to achieve optimal performance. Rigorous testing and failure mode analysis are incorporated at every stage from design to mass production, ensuring reliable performance and risk prevention.
