The Haier MRV S II is a high-performance DC Inverter outdoor unit designed for flexible commercial HVAC applications. Featuring a compact, front-discharge design, this unit is engineered for installation in confined spaces while providing a robust power range from 4 to 12 HP. It incorporates advanced technology including a high-efficiency Twin Rotary DC Inverter compressor and a large aerodynamic fan, ensuring superior energy efficiency and a significantly reduced operational noise level. Built for versatility, the MRV S II offers an impressive static pressure of up to 30 Pa and allows for pipe lengths reaching up to 300 meters, providing immense flexibility for complex site requirements. The system supports direct integration with third-party BMS or BAS via the built-in MODBUS RTU protocol, eliminating the need for extra gateways. Additionally, the unit features the proprietary Self-Clean function, which helps maintain indoor air quality by removing dust and bacteria from the evaporator through a cycle of freezing and defrosting. This model utilizes R410a refrigerant, making it a reliable solution for demanding environments.
