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

Stand alone thermostats 33T

4 types of thermostats:
  • Type A : a two-pipe application equipped with alternating current motors
  • Type B : four or two-type applications equipped with electric heating and alternating current motors
  • 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.

NTC controller

  • PID controller
  • Carrier Communication Network (CCN) AQUASMART compatible
  • AC or EC motor management
  • Combines energy saving with optimized comfort

WTC controller

  • Open communication protocol BACnet
  • Communication PID controller
  • Large range of user interfaces
  • Manages the motorized louvers of the grill
  • Manages the EC motor for optimized comfort
  • Optional lighting and/or blinds management modules
