Fans

Can be equipped either with centrifugal fans of double width (DIDW) or with free flow plug fans. The centrifugal fans can be either low pressure type with forward blades or high pressure type with backward curved blades, forefinger backward curved blades or aerofoil curved blades. All fans impellers are statically and dynamically balanced accoding to ISO1940, thus eliminating any possibility of vibration. All fan supplied in Klimallco DAK series are tested in a registred laboratory in accordance with ANSI/AMCA 210 laboratory Methods of Testing Fans for Rating and AMCA 300 Reverberant Room Method for Sound Testing of Fans.

Transmission is effected via V-belts and pulleys with taper lock bushing, adjustable pulleys up to size 180 mm can be supplied upon request. The Fan/Motor assembly is elastically suspended inside the unit, either by RIS or Spring type vibration isolators, thus eliminating the need of external isolators.

Different fan positions are available depend on the requirements. The fan outlet is connected to the unit panel by means of plasticized fabric, to avoid any transmission of vibration to the panel.

Unobstructed and uniform internal unit flow, which lead to a better performance of inside components such as coil and filters. In addition, the absence of pulleys has a positive effect on flow uniformity. Klimallco possessing the necessary expertise and knowhow for this type of application, can offer complete built in control panel.

In all fan sections, in addition to the service door, Klimallco offers as standard a second safety door with net screen, to eliminate the use of a belt guard and avoid unauthorized people touching moving parts.

 

EC Motor Fans

Single inlet; direct drive; high-performance radial impeller with circu-mferential diffuser mounted on an electronically commutated external-rotor motor with integrated control electronics; radial impeller made of aluminum with backward curved, continuously welded blades, aerodynamically optimized inlet nozzle with bleeder connection for pressure relief made of zinc-coated sheet steel; complete unit statically and dynamically balanced in two planes as per DIN / ISO 1940 to balancing grade G 6.3; EC external-rotor motor, efficiency class IE4 without "rare earth" magnets being used, with maintenance-free ball bearings and permanent lubrication; nominal lifetime 40,000 operating hours; wide voltage input 1-200- 277 V, 50/60 respectively 3-380-480 V, 50/60 Hz; unit can be operated on all standard Electricity Board networks at identical air performance; optimized motor technology; soft start; integrated current limitation; connection via brought-out variable cable connector (motor size 084) or easy- to-mount and robust integrated terminal box made of aluminum extremely compact electronics; with adjustable PID controller meets all relevant EMC directives and all requirements as to circuit feedbacks; requires no complicated installation with shielded cables; very low-noise commutation logic; 100 % speed-controllable. Motors with an output of 750W or higher have an RS485/MODBUS RTU interface. Any potentially necessary constructional measures for structure-borne sound insulation have to be provided by customers.

In all fan sections, in addition to the service door, Klimallco offers as standard a second safety door with net screen, to eliminate the use of a belt guard and avoid unauthorized people touching moving parts.
Optional: Modules with increased corrosion protection.

 

Motors

Three phase asynchronous low Voltage motors with sguizzel cage , totally enclosed IP 55 fan cooled, TEFC type, insulation class F, with build in PTC thermistor, high energy efficiency IE2 class . All motors are suitable for variable frequency inverter (VFI) at 50 and 60 Hz operational range and comply with all relevant international standards and specifications such as   DIN, EN, IEC, VDE.
Upon request motors can be:

  • multi speed,
  • specific voltage,
  • rated IP 56 and IP 65 ,
  • ATEX regulation motors,
  • Premium efficiency IE3 or super premium efficiency IE4

Each fan motor can be supplied with variable frequency inverter for controlling the rotational speed of electrical motor by controlling the frequency of the electical power supplied  to the motor. The variable frequency motors on fans save energy by allowing the volume of air moved to match the system demand.
