Direct Expansion System – Refrigerant flows directly through the cold plate or evaporator without secondary coolant, eliminating pumps, reservoirs and associated piping. This reduces system components, minimizes failure points, and enables seamless integration into compact medical, laser and mobile cooling equipment.
Medical & Laser Precision Cooling – Designed for medical devices, aesthetic equipment, laser systems and optical instruments requiring stable temperature conditions. The brushless DC inverter compressor provides precise thermal control for sensitive components.
Compact & Lightweight – Up to 20 times smaller and lighter than traditional liquid chillers. Suitable for space-constrained installations in portable medical devices, laser modules, and compact car freezer cabinets.
High Heat Transfer Efficiency – Direct contact between refrigerant and cold plate ensures the highest heat transfer rates. 40% higher cooling capacity compared to indirect liquid cooling systems.
Brushless DC Inverter Compressor – Variable speed from 2,000 to 6,500 rpm optimizes cooling output and energy consumption. Energy-efficient operation extends battery life for mobile and portable applications.
Low Noise & Vibration – Noise level below 48dB. Optimized compressor mounting and fan design reduce vibration, ensuring quiet operation in medical environments, vehicle cabins and outdoor settings.
Wide Application Coverage – Suitable for medical devices (laser therapy, diagnostic instruments), optical equipment (CCD cameras, sensors), and mobile cooling (car freezers, portable coolers, boat refrigerators).
Flexible Refrigerant & Voltage Options – Supports 12V/24V/48V DC and R134a/R290/R1234yf refrigerants, accommodating different regional regulations and system requirements.
Stable Bulk Supply – Standard models ship in 15–25 days, supporting rolling replenishment and reducing inventory capital occupation.
OEM & ODM Support – Custom logo, packaging, voltage, connectors and tubing lengths available. Can produce according to customer drawings or specifications.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
