INV 10

General Specification

The INV10 is a compact controller designed and programmed for managing air-cooled and water-cooled chillers, as well as controlling air-handling systems and air-cooled package units with single and dual refrigeration circuits. It includes:

• 10 digital inputs
• 10 digital outputs
• 6 analogue inputs and 2 analogue inputs on the INV-2EUBN module
• 2 analogue outputs
• RS-485 port for serial communication
• Electronic expansion valve controller
• Internal Bluetooth
• SIM card

Main Functions

In summary:

• Control of the compressor, condenser fan, evaporator water pump, or condenser fan, and antifreeze
• Temperature control of the chiller water using inlet and outlet water temperature or differential temperature
• Control of the condenser fan speeds
• Control of the compressor speed
• Comprehensive management of alarms
• Full control of the electronic expansion valve
• Capability to control 2 refrigeration circuits as a master/slave
• Programming of inputs and outputs based on user requirements
• Upload and download configurations via PC using the internal serial port and Bluetooth port, or through the internal display
• Compressor flow control and prevention of phase imbalances

Electronic Expansion Valve Controller Driver INV-2EVB

The INV-2EVB is a universal driver designed to control electronic expansion valves using the superheat value calculated by the expansion valve controller. This driver has the capability to control various types of Unipolar and Bipolar valves available in the market from brands such as Danfoss, Carel, Sporlan, Alco, Sanhua, and others. The control method used for regulating these valves employs a PID controller, which precisely manages the refrigerant flow with very high accuracy.

Compressor Flow Control Module INV-CT1

This module monitors the compressor current moment by moment by connecting to the current transformer (CT). In the event of a rise in compressor current beyond the safe threshold, it prevents potential damage to the compressor system.
