BESB box ventilators

BESB BOX VENTILATORS

BESB box ventilators are made from Aluzinc® AZ185 class C4 in accordance with EN/ISO12944-2 and insulated for sound and condensation with 50 mm mineral wool.


As standard BESB can handle a gas temperature of up to 80°C, but can be ordered in a special version for temperatures right up to 200°C.

When used as a smoke extract fan, BESB can as standard handle up to 300°C for 60 min.

DESIGN

Fan Impeller

The ventilator impeller is a B-impeller made from cast aluminium.

It has backward curved blades, thus ensuring low energy consumption and the further advantage that less dirt is attracted, with impaired impeller efficiency as a result.

Spigots

The spigots on BESB have rubber gaskets, with a transition piece on the extract side specially developed for minimum pressure drop.

OSCILLATION DAMPERS

To minimize noise and vibration, the box ventilator is fitted as standard with efficient oscillation dampers mounted on brackets.

SPLIT HINGES

The BESB box ventilator has split hinges, which enable the door to be removed for installation and servicing, even in very confined conditions or for transport to difficult locations.

CONDENSATION OUTLET

The BESB box ventilator is designed to transport air with an air humidity of less than 80% RH.

BESB is available as a special model with a condensation outlet for air with over 80% RH.

Split Version

If there are problems moving the BESB box ventilator in one piece, it may be ordered in a SPLIT version.

– The box ventilator must be assembled by an EXHAUSTO-approved fitter
– The box ventilator must receive final testing before handover by the fitter.

ENERGY

BESB box ventilator

The BESB box ventilator is a low-energy ventilator, in which ventilator housing, centrifugal impeller and motor all work together as one technology.

All BESB box ventilators fulfil the future requirements for 2015 laid down in the Ecodesign Directive EC327/2011.

BESB is listed by the Danish electrical power utility companies as an ‘energy-saving fan’® – that is a highly energy-efficient ventilator.

MOTOR TYPES

BESB box ventilator

BESB box ventilators have their motor connected directly to the ventilator impeller.

BESB box ventilators are available with three types of motor:

– EC motor
– single-phase motor
– 3-phase motor

The motors are made to protection class IP54 and all materials are as a minimum class F (155 °C). All motor types have integral current overload protection.


EC motor

The EC motor for BESB is a permanent-magnet motor of class IE5 with motor control for 1 x 230 V or 3 x 400 V connection. The motor control and the motor are protected from overloading, blocking, over and under voltage, and over heating.

The motor control is factory programmed by EXHAUSTO for optimal operation of the ventilator. It only requires mains connection and a control signal from an EXHAUSTO EFC1P or MAC12 controller or a 0-10V signal.

The motor controls also provide a Modbus interface for fan control and alarm read-offs etc.


Single-phase and 3-phase motor:

Single-phase motors can be selected for BESB250. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO controllers EFC16, EFC35 and MAC12 (with MPR4 or MPR8 module).

3-phase motors can be selected for BESB500. The motor is designed for a fixed rpm of 1400 or for frequency control (max. 50 Hz) by external frequency converter. The 3-phase motors must use external motor protection, or they can be controlled by an external frequency converter (with integral motor protection) to max. 50 Hz.
