Air-Cooled Central Inverter

Industrial Central Inverter Series

The structural features of the Scroll compressor, the use of a vapor injection kit (1), system operation with an inverter (2), and effective pressure control (3) increase efficiency by 34%. Thus, with the VRC Plus® system, the system continues to operate with optimum efficiency even under the harshest conditions.
When the compressor running with the inverter operates at low speeds, the lubrication system slows down and the compressor heats up faster. For this purpose, a liquid injection system is included in the compressors. Liquid injection engages when compressors heat up and cools the compressor down. Furthermore, all compressors feature a smart oil level float switch. This system prevents the compressor from running out of oil; even if it does, it cuts off power to the compressor and warns the user. Even if a compressor fails, the remaining compressors back up the failed compressor. (4)
It occupies 1/3 less volume compared to hermetic compressor systems of similar capacity. Additionally, it is 1/4 lighter. This avoids installation time difficulties and adapts to all types of environments.
The continuous compression process and minimal moving parts of the scroll compressor used in the system, alongside speed-controlled operation (5) of condenser circuit fans, reduce noise levels by an average of 2/3 compared to other systems.

Thanks to the Grundfos GO app, you can easily verify the compatibility of both integrated and standalone circulator pumps and receive guidance on setting the correct curve for the pump you are replacing.
The pump display allows the user to see the current power consumption of the circulator pump, helping to identify whether there is any issue in the system.
Non-magnetic shaft and bearings reduce the risk of blockage caused by dirt or magnetite, while the bearing system helps prevent scale accumulation. In the unexpected event of a pump blockage, the motor will continuously attempt to start at maximum torque to guarantee startup even in demanding conditions.
