CX3000, Ceiling unit

CX3000 Ceiling units

Description of CX3000 series

CX3000 ceiling units are available in six sizes, covering airflows up to 3,300 m³/h (ERP18). The CX3000 is designed for integration into a suspended ceiling, or fitting into a ceiling or floor partition. The CX3000 is a highly space-efficient solution, suitable for renovation or new build projects. 

The CX3000 can be selected in a LEFT or RIGHT version. Water heating coil (HW) for installation and additional coils for duct mounting are available as accessories: electric pre-heating coil (PHE), electric post-heating coil (AHE) and/or cooling/heating coil (CCW).

The CX3000 is controlled by the advanced EXcon control system.

Doors

The CX3000 is equipped with hinged doors that can be opened on both sides. If the location and space make it difficult to fit the suspended doors, we can supply rails (accessories) that are mounted under the unit so that the doors can be dismantled and placed on the rails while the unit is being serviced.

Delivery

The CX3000 series is a stock item, which is why the delivery of the unit and selected accessories will take place directly from the central warehouse in Europe.

Configuration

Use our EXselectPro configuration tool to calculate the solution, select the correct size and put together the accessories required for the project. 

All CX3000 units are supplied as a standard basic model in either the right or left variant. Accessories are supplied separately as kits/parts and are installed in connection with the installation of the unit.   

Commissioning:

All CX3000 must be commissioned to ensure that the unit is correctly set up. This is done via a windowsprogram, CX3000 Configurator, which can be downloaded via the link at the top of the page.

Configuration takes place via a LAN cable connected to the EXcon-Master-Module and a PC.

Cabinet
	The cabinet is constructed of 0.8-mm galvanised steel corrosion class C4 in accordance with EN/ISO12944-2and insulated with 50 mm mineral wool. This results in low noise emissions to the surrounding environment.

Control system for CX3000

All CX3000 units are available with integral EXcon control systems for optimum control of the indoor climate in practically every application area.

EXcon control systems can be used for controlling airflows, heating, cooling, etc. The operating program is configured for how and when the control system will switch between the integral functions.

The operation of the unit is constantly monitored by the EXcon control system, which protects the counterflow heat exchanger against icing, against frost damage to the water heating and cooling coils, and against overheating of the electric heating coils.

Using the 3 integrated protocols BACnet IP, Modbus TCP/IP or Modbus RTU, it is easy to monitor virtually all parameters via BMS, as well as control the operation of the system.

With the EXcon control system’s many functions, it is possible to optimise and adapt the system's operation to achieve the most energy-efficient regulation by e.g. compensating for the outdoor temperature, changing the regulation to suit the summer or winter season, limit active cooling or heating, automatically lower the temperature setpoint and cool down the building at night during the warm summer periods.

Integrated functions in the EXcon control system for CX3000:

• Automatic temperature reduction in low-speed operation
• Alarm and data log
• Control using a day, week or year plan
• Extended operation for set periods
• External switch between regulation levels
• Alarm email (requires local mail server)
• Summer night cooling
• Outdoor air temperature compensation
• Automatic summer/winter time changeover
• Filter monitoring via pressure measurement

• Connection to CTS/BMS via BACnet IP, Modbus TCP or RTU (over 900 registers)

• 2 configurable digital inputs for:
  - Fire alarm (factory setting)
  - AHU emergency stop
  - Manual override for Low speed
  - Manual override for Medium speed
  - Manual override for High speed (factory setting)
  - Frost alarm

  - External reset of alarms

• 2 configurable outputs for:
  - Operating signal (factory setting)
  - An alarm (factory setting)
  - B alarm
  - Alarm reset
  - Summer night cooling active
  - Summer season active
