Sanhua has developed its latest generation of Variable Speed Drives dedicated to hermetic scroll and rotary compressors, which is designed for applications using natural refrigerants such as CO2
(R744) and propane
(R290). SD2 Variable Speed Drives have been developed to operate with BLDC refrigeration compressors considering the most critical point such as operating envelop, oil management, temperatures and torque to ensure the best reliability ever with max. efficiency over 95%. SD2 drives are adapted for heat pumps with heating capacity up to a 46kW/compressor* or for refrigeration racks and condensing units used in small stores with a cooling capacity up to a 35kW/compressor*. At Sanhua all drives are tested with compressors that are selected by customers in our TÜV certified laboratory. This ensures a perfect match for your application. SD2 drives used together with Sanhua Electronic Expansion Valves provides a stable evaporating temperature and reduces compressors short cycles. A stable control allows higher evaporating temperature and lower condensing pressure, which are key to saving energy and possible with Sanhua’s SD2 and EEVs control.
*Based on COP of 3 for cooling and 4 for heating. Heating capacity with the following conditions : Evaporating t°C=-7℃, Condensing t°C=50℃, Subcooling=5K, Superheat=4K. Cooling capacity using the following conditions : -8°C evaporating, +32°C ambient temperature.

With increased energy costs, it is important to maximise the efficiency of refrigeration systems. Refrigeration equipment uses significantly more energy when the refrigerant charge is less than optimal. Even low-level refrigerant leaks can impact equipment efficiency over time and with refrigerant leak posing risks to both people, places and the planet, the sooner a refrigerant leak is found, the sooner it can be fixed.
The MSA Connected Solution combines cloud notification and
reporting software with low-level fixed and portable refrigerant detection hardware. It helps you find refrigerant leaks fast and thereby enables you to fix them fast. The Connected Solution brings you greater visibility of refrigerant leaks across your enterprise with 24/7 alerting, notifications, and reporting across all your sites and refrigeration equipment. It also supports your regulatory compliance with reporting tools and regulatory workflows for EPA 608, CARB, and F-Gas. Support your organisation’s energy saving, and carbon neutral sustainability goals with the MSA Connected Solution for an effective refrigerant leak response.
