-
■ Adopting a new 5-6 patented asymmetric rotor tooth shape linear design with twin screws, it improves compression efficiency, has fewer moving parts, no vulnerable parts, and can operate for up to 80000 to 100000 hours without faults.
-
■ The unit casing is made of high-quality steel plate and coated with anti-corrosion paint, effectively preventing rust and adapting to various harsh outdoor conditions. The unit directly exchanges heat with the atmosphere, without environmental pollution.
-
■ The mechatronics integration design eliminates the need for users to set up specialized electrical control cabinets. The intelligent control system can automatically monitor and control the operation status of the unit, and display the cause of faults, facilitating unit maintenance.
-
■ The intelligent defrosting control of the unit can reduce the defrosting frequency and avoid false defrosting. When defrosting the dual compressor unit, the system takes turns defrosting to maximize user comfort.
-
■ The unit is designed as a whole and can be installed on outdoor roofs or floors. It can achieve three functions: refrigeration, heating, and domestic hot water. It can meet various comfortable and technological occasions such as hotels, hospitals, office buildings, shopping malls, apartments, factories, etc.
-
■ The unit is equipped with an electronic expansion valve, which can accurately control the refrigerant flow rate, enabling the unit to adapt to various working conditions and achieve various control functions.
-
■ Accurate temperature control of chilled water outlet. Each sensor in the system can quickly and accurately transmit signal data to the controller, and the controller accurately adjusts to ensure more stable unit operation and timely protection of the unit.
-
■ Adopting a highly intelligent microcomputer control system, international famous electrical components, and equipped with RS485 communication interface as standard, the controller can add communication protocol interfaces such as Modbus, making it easy for customers to achieve centralized control or building automation for networked group control of units, and achieve joint control of multiple units. (Optional).
