IdroFan® - Coanda effect cassette
42KY
Cooling capacity : 1.2-5 kW
Heating capacity : 1.7-6 kW
Energy performance, comfort and indoor air quality: Carrier's new 42KY cassette is the all-in-one solution to meet heating and cooling requirements for commercial buildings and provide optimum comfort for users.
- Optimized Coanda Effect diffusion
- Indoor comfort
- Air quality
- Responsiveness of the system and individual adjustment
- Low energy consumption
- Acoustic comfort
- Design
- Ease of maintenance
This cassette is a 600 x 600 mm format existing in 3 sizes and available in:
- 2 pipe, for heating and/or cooling mode
- 2 pipe + electrical heater, for heating and/or cooling + electrical mode
- 4 pipe, for cooling and heating mode
Innovative design
- Next generation chassis that combines high density EPS for its thermal and phonic properties, ABS PC and a ribbed galvanized sheet steel base to stiffen the assembly
- Chassis with unique dimensions for all sizes, adapted to the suspended ceiling grid size 600 x 600 mm
- Hydraulic, air and electrical connections on the same side to facilitate installation and access for maintenance operations
Design for comfort & energy optimization
- Greater comfort
- Optimized Coanda Effect diffusion for perfect control of thermal phenomena that can cause discomfort and make the room feel draughty
- Anti-cold shower effect
- Compliance with energy requirements
- Specially developed temperature exchange coils to meet the requirements of low energy buildings
- Optimized temperature exchange coils to limit cost and consumption in comparison with the other components of the installation
- LEC low consumption motor
- Reduction in power of the electric heating coils to match the requirements of new buildings
Ease of installation and operation
- Designed to be easy to fit and not require many on-site operations
- Optimized weight and size to facilitate handing during installation
- Safety system to suspend the diffuser leaving the technician's hands free to tighten the mounting bolts
- Access to internal components without the need to open suspended ceilings, easy to open filter hatch grille that is hinged to facilitate maintenance operations
- Diffusion panels supplied in individual packaging, making it easier to fit the unit with no risk of damaging or soiling visible parts during installation
Eco-design
- Raw materials : 30% saving in weight and 21% saving in volume thanks to a compact and well thought out architecture. Use of easily recyclable materials (EPS and ABS)
- Transport : raw material suppliers selected from those that are less than 100 km from our manufacturing and packaging factory, enabling a 50% gain in volumes transported (reduction in CO² emissions)
- Recycling and easy of disassembly : 90% recyclable products. Materials can be completely separated and fixings have been reduced by 40% to allow greater efficiency at recycling plants

This table provides a quick and easy overview of the key features of our products. To learn more about them and make the best choice, consult their detailed product sheet.
*Stand alone : Lead/lag configurable via the device for the application once the KNX bus is connected. BMS not required in this case.
