What are the control options for each size of the Cotes Desalter and what does that mean?

All models are plug-and-play systems that automatically regulate themselves during normal operation. Once installed and started, they continuously maintain the required climate conditions without ongoing manual adjustment.

CD26 – Simple, robust operation

The CD26 is designed for straightforward operation without a programmable logic controller (PLC).

Control options include:

• Start/Stop operation
• A digital run signal indicating whether the unit is operating

The CD26 is ideal where simple and reliable operation is required, with minimal integration into a building management or monitoring system.

CD35 and CD65 – Advanced control and monitoring

The CD35 and CD65 both include an integrated PLC and offer identical control functionality. In addition to simple Start/Stop operation, they provide enhanced communication, diagnostics, and optional operating adjustments.

Available control interfaces include:

• Web interface
• Modbus TCP
• Digital control signals

The PLC also provides access to alarm and diagnostic information through the web interface and Modbus TCP, making system monitoring and troubleshooting easier.

Although no operator intervention is normally required, two optional operating parameters can be adjusted if needed:

1. Power Level

The Power Level function allows the airflow to be increased or decreased relative to the nominal operating point.

• Adjustable between 70% and 130%
• 100% is the nominal factory setting
• Airflow changes approximately in proportion to the selected Power Level

Increasing the Power Level above 100% increases airflow but slightly reduces the range of outdoor climate conditions under which the unit can maintain its specified airflow ratio and humidity setpoint.

2. Reduced Mode

Reduced Mode is intended for situations where minimizing power consumption is more important than achieving maximum drying performance.

When Reduced Mode is activated:

• Heater power is limited to 50% of maximum output
• Airflow is reduced to approximately 75% of nominal capacity
• Any selected Power Level setting is ignored

This mode can be useful during periods of lower drying demand or where energy consumption needs to be limited.
