Idrofan® - Low-consumption individual comfort module for variable air volume system
42BJ
Cooling capacity : 1-5.4 kW
Heating capacity : 1-6 kW
Air flow : 140-900 m³/h
The Carrier 42BJ ICM (Individual Comfort Module) is a compact air conditioning system available in 3 sizes, designed for conditioning rooms measuring 25 to 50 m².
- All-in-one offer: minimal installation costs thanks to factory-tested and fitted-options
- Easy integration into a centralized zone
- Very low sound level
- Available static pressure: 100 to 350 Pa

General description
- Connected by flexible sound-absorbing ducts (heat insulated air discharge duct) to one or more plenums
- Can be fitted in suspended ceilings or raised floors, ideally in corridors, where they are connected to hot water, chilled water and fresh air circuits
- Designed to be ultra quiet
Comfort
- Equipped with a Carrier digital control, providing each occupant with a remote user interface located on their desktop or wall and enabling individual selection of room temperature, forced air function, occupied/unoccupied mode
- Aquasmart Evolution is used to control and optimize each module to obtain the best balance between energy savings and individual comfort
Indoor air quality
- In this application, each individual comfort module (ICM LEC) is equipped with a fresh air intake control and high-efficiency filtration to successfully protect against any type of pollutant
- High efficiency filtration : type F5 or F6
- Fresh air flow modulation system to control the air flow diffused in a room
Three objectives
- Adapt the ventilation flow rate to the actual occupancy of the rooms
- Maintain excellent indoor air quality to ensure the comfort and health of occupants, in accordance with the labour code
- Control energy costs relating to air change in rooms to avoid "over-ventilating" the building and to minimize operating costs, particularly when the building is unoccupied
Operating principle
- A CO2 sensor measures the concentration of the room
- The sensor sends a signal to the Carrier digital controller which, in turn, sends a signal to actuate the fresh air valve
- If the concentration is below a threshold value, the air flow is at minimum, if it is above, the flow rate is increased
Stand alone thermostats 33T
2 types of thermostats:
- Type C : a two-pipe application equipped with EC motors
- Type D : four or two-pipe applications equipped with electric heating and EC motor
Wall-mounted controls can easily and discreetly be integrated into any room environment. The operating range goes from 10°C to 30°C.
