Dündar Hot Environment fans are specially designed centrifugal fans that can handle temperatures up to 120 degrees. They are used for ventilating and cooling existing environments.

Applications of Hot Environment Fans

• Venting hot air in high-temperature areas
• Channel applications where axial fans are insufficient
• Solid fuel boiler systems

Fan Casing and Impeller

• Radial casing with an intermediate cooling impeller to prevent heat transfer to the motor
• Cold-drawn high-quality DKP steel radial casing
• Environmentally friendly electrostatic epoxy powder coating for high corrosion resistance
• Forward curved radial impeller with ISO 1940 dynamic balancing
• High pressure and flow rates with nozzle application at the inlet
• Strong and smooth casing structure with special crimped joint
• Low noise level

Motor

• High-quality production using advanced CNC machines
• Aluminum-finned motor casing with high heat conduction capacity
• Insulation Class F for a wide working range from -40° to +70°
• 230 V / 50 Hz Single-phase fan motor
• 400 V / 50 Hz Three-phase fan motor
• Certified components meeting standards
• IP 54 protection class (optional IP 55 production available)
• Three-phase fans can use inverter control (drive control)

Important Considerations for Fan Selection

Four parameters must be considered when selecting a fan:

• Required air flow
• Pressure losses
• Acceptable noise level
• Electrical power connection type

The required air exchange rate for the ventilated environment depends on its usage purpose, the number of people, and activities involved. Below is a table showing the required air exchange coefficients for different environments:

Table: Air Exchange Coefficients Based on Environment

Environment	Air Exchange Coefficient
Auditoriums	6-8
Paint Booths	25-50
Safe Deposit Rooms	3-6
Cinemas and Theaters	5-8
Commercial Kitchens	15-30
Foundries	8-15
Gymnasiums	4-6
Laundry Rooms	10-20
Indoor Pools	3-4
Restaurants	8-12
Conference Rooms	6-8
Waiting Rooms	4-8
Machine Rooms	10-40

Based on these, the required air flow is calculated as follows:
Q [m³/hour] = Air exchange coefficient (per hour) × Room volume (m³)
Or
Q [m³/hour] = Number of people × Air flow per person

After determining the required air flow, an appropriate duct design (considering noise and air speed criteria) should be made, and pressure losses should be calculated. Depending on the environment where the fan will operate, the fan type (axial, radial, roof, smoke extraction, etc.) should be chosen, and an appropriate fan curve should be selected based on the determined flow-static pressure pair.
