Product Overview

aicore™ air is the future of controls solutions for dry operation cooling applications primarily focusing to provide cooling to the water or refrigerant medium by synchronously ramping EC fans. Combined with advanced features around precision cooling, this guarantees the most exact energy efficient control to maintain the desired outlet temperature or inlet pressure for coolers and condensers.

The aicore™ air controller can be flexibly integrated into different control systems using our wide range of operating modes and interfaces.

With a focus on data, additional features support optimization, ease of use, maintenance, and serviceability to ensure uptime. With aicore™ cloud IoT solution, all this data and functionality are combined with our analytics to provide the highest level of efficiency and support.

Benefits at a glance

AICORE™ CLOUD READY

To maximize capability, all aicore™ products are built to synchronize with aicore™ cloud, ensuring a complete 360° view of the equipment while providing actionable insights and analytics in real-time.

FREE COOLING

To benefit from times of operation when the dry cooler can provide all of the needed cooling without the chiller/compressor, a modulating valve allows for partial load and full load operation. This fea-ture can be automatically initiated by monitoring ambient temperature and inlet and outlet temperatures at the chiller.

HEAT RECOVERY

Through valve modulation, the controller determines if enough heat is possible to effectively be re-covered (Tmin) and as well direct excess heat through the heat exchanger when needed (Tmax).

BYPASS VALVE CONTROL

Operating as a dry cooler, a bypass valve prevents excessive cooling during colder months and al-lows for exact control by bypassing the coil both partially and completely, depending on demand.

ADVANCE THRESHOLD

Allows the user to pre-set a trigger to drive a function or output signal, based on a combination of temperatures, pressures, and control values. Emergency Mode through threshold enables the controller to automatically detect a high temperature or pressure, setting fans to maximum as a failsafe.

PLUG N’ PLAY

Using our control system, each EC fan has its own dedicated Modbus signal enabling a plug n’ play system. Immediately recognizing and parameterizing each fan for the application. Standard communication protocols and flexibility through control with different operating modes allow for setpoints to be automatic, remote, or even directly follow the client control signal.

PARAMETER LOAD/SAVE

The ability to save, load, and create new parameter sets directly for the application allows for con-sistent set-up and operation across an entire fleet of cooling equipment, increasing the reliability and allowing for simple rapid commissioning.

WINTER OPERATION

In low-ambient temperatures, NCC mode (Natural Convection Control) prevents cooling through internal convection by reversing fans to trap the warm air from the coil, allowing for the highest precision of control and prevention of over-cooling. Additionally, with the break-free light ice and snow removal feature of the EC fans, a reliable winter cooling solution is offered.

MAINTENANCE & CLEANING

Ensures that during extended periods in which the heat exchanger is non-operational, the fans are switched on at regular intervals to prevent damage. To keep the heat exchanger coil clean, fan rotation is reversed at regular intervals to regularly blow out debris. Together these functions always keep the unit ready for operation.

SAFE OPERATION

In the unlikely event of failure, bypass operation is automatically switched over to keep the system always running reliably.

LOW CAPACITY MOTOR MANAGEMENT (LCMM)

During low load demand, Low Capacity Motor Management ensures efficient and exact control of each individual fan only running the necessary ones at their lowest speeds, enabling further energy savings and avoiding performance fluctuation throughout the entire system.
