Specification for the car park
COLT CYCLONE CAR PARK INDUCTION JET FAN
General description
Cyclone is an induction fan designed for the ventilation of car parks, so as both to reduce carbon monoxide levels and to assist with the extraction of smoke in the event of a fire.
Induction fans use tunnel ventilation technology to eliminate the need for costly and bulky ductwork. Compared to ductwork systems, this may save car-parking spaces, reduce running costs and noise, and make the car park a lighter, less cluttered environment.
Scheme Design
Each car park is different and Colt will provide a scheme design to suit the exact requirements of the project. Colt Car Park Ventilation Systems include one or more of the following elements:
- Natural inlet through the entrance/exit ramps/fixed ventilation louvres.
- Extract by a ducted system with dual fans discharging to atmosphere.
- Air distribution and mixing within the car park by a network of Cyclone Induction Fans or Jetstream Impulse Fans.
As part of a designed scheme involving detection, controls and extract units, Cyclone adds momentum to the air to thrust it towards an extract point.
In general, for day to day operation the control system monitors the carbon monoxide levels within the car park and once a set point has been reached the system increases the ventilation rates. Once a signal from the fire alarm has been received, ventilation rates are increased.
Versions
- Two fan sizes, with thrusts of 100N and 50N, and overall depths of 320mm and 255mm respectively
- Single speed generally used with inverter control
Finishes
Cyclone is supplied as standard in polyester powder light grey RAL 7035, with the option of a polyester powder coating to any RAL colour.
Technical Data
Cyclone 50:
Maximum thrust of 50 N, equating to a volume flow rate of 1.8 m³/sec
1300 rpm at top speed, motor rated at 1.4 kW, with FLC of 2.8 A and SC of 13 A.
Cyclone 100:
Maximum thrust of 100 N, equating to a volume flow rate of 2.7 m³/sec
1300 rpm at top speed, motor rated at 2.6 kW, with FLC of 4.6 A and SC of 15A.
Certification
Both Cyclone 100 Cyclone 50 and their standard isolators fully meet the F300 time/ temperature classifications of EN 12101-3 (300°C for 1 hour). Test Certificates are available on request.
Noise output
CIBSE Guide Volume A: 1999, Environmental Design, sets out a recommended maximum noise level of NR55 in car parks. There is no equivalent generally applicable recommended external noise level. All Colt Cyclone units are designed to achieve a maximum noise level of NR55 within the car park at 3m from the unit in normal day to day operation. Lower target noise levels may be able to be designed in.
