Product Features:
Superior Performance: Equipped with internationally renowned semi-hermetic screw compressors, which integrate motors and compressors to prevent refrigerant leakage. When multiple compressors are installed, the control system alternates their operation to balance load and extend unit life. The units feature multiple refrigerant circuits, allowing continued operation even if one circuit requires maintenance. The compressor uses unloading and step-down voltage starting methods to minimize power system impact. It also features ultra-low noise blade design and a V-type structural design for efficient cooling.
Unique High-Temperature Type Chiller:
This high-temperature heat pump can provide up to 55-60°C hot water for heating and sanitary use. The concept of "large temperature difference, small flow" aligns with energy-saving principles, making it ideal for various applications.
Easy Installation:
Compact structure saves space, and the machine is pre-filled with R22 refrigerant and lubricant at the factory, reducing installation time and costs. Minimal vibration allows for easy vibration isolation, and installation only requires connecting water pipes to the evaporator.
Low Operation and Maintenance Costs:
The unit offers intelligent control based on load demand, with four-step (100%, 75%, 50%, 25%) capacity adjustment available. This helps save energy during partial load operations. The screw compressor has only 1/10 of the parts compared to reciprocating compressors, resulting in fewer wearing parts and no inlet/outlet valves, ensuring a very low failure rate. The screw compressor can operate trouble-free for up to 40,000 hours.
Comprehensive Security Protection:
Pressure protection includes high and low pressure protection devices. Motor protection covers loss of voltage, phase loss, reverse-phase, and internal overheat protection. Anti-frozen protection stops the unit when chilled water temperature is too low. A safety valve automatically opens when refrigerant pressure exceeds a certain threshold, ensuring the unit's safe and stable operation.
Optional Devices:
Partial or total heat recovery systems are available.

The role of the valve is specifically responsible for the input of air into the engine and exhaust the exhaust gas after combustion. From the engine structure, it is divided into intake valve and Exhaust Valve.
The role of the intake valve is to draw air into the engine and mix it with the fuel to burn; The function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat.
The valve is composed of a valve head and a rod. The valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also withstand the pressure of the gas, the valve spring force and the transmission component inertia force, its lubrication, cooling conditions are poor, requiring the valve must have a certain strength, stiffness, heat and wear resistance.
The intake valve is generally made of alloy steel (chromium steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel).
Sometimes in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy, and the rod is made of chromium steel, and then the two are welded together.
