FOR THE PRECISE CONTROL OF NORMAL TO HIGH CONSTANT VOLUME FLOWS

Rectangular self-powered volume flow controllers for the control of supply air or extract air in constant air volume systems

  •  Mechanical system-powered, without external power supply
  • Suitable for supply and extract air
  • Correct operation, even under unfavourable upstream and downstream conditions (straight length required upstream 1.5 B, downstream 0.5 B)
  • Close tolerances on flow rate
  • Flow rate setting using pointer on external scale, scale accuracy approximately ± 4 %
  • Flow rate range 4 : 1
  • Damper blade shaft supported in bearings
  • Bellows also acts as an oscillation damper
  • Differential pressure range 50 to 1000 Pa
  • Independent of orientation
  • Damper blade mechanisms maintenance-free
  • Operating temperature range 10 to 50 °C


Simplified installation

The Type EN and END volume flow controllers are fitted with flanges on both ends. This ensures very low leakage at the joint.

Acoustic requirements

Depending on requirements, a TX silencer may be supplied to reduce the air-regenerated noise.(installed by others).

General information

Constructional features

  • Rectangular form, rigid frame Flanged at both ends, suitable for fitting System 30 connecting sections.


Casing

  • Casing and damper blade made of galvanised sheet steel.
  • Stainless steel leaf spring.
  • Polyurethane bellows
  • Plain bearings with PTFE coating

Nominal sizes

  • Nominal sizes from 400 × 30000 – 600 × 600 mm


Variants

  • EN: Volume flow controller
  • EN-D: Volume flow controller with acoustic cladding
  • Units with acoustic cladding and/or secondary silencer Type TX for demanding acoustic requirements


Construction

  • Galvanised sheet steel
  • P1: Powder-coated, silver grey (RAL 7001)


Parts and characteristics

  • Ready-to-commission controller
  • Damper blade with low-friction bearings
  • Bellows that acts as an oscillation damper
  • Cam plate with leaf spring
  • Rotary knob with pointer and scale for setting the volume flow setpoint value
  • Aerodynamic functional testing of each unit on a special test rig prior to shipping
  • Visual display of damper blade position for operating point optimisation


Actuators

  • For setpoint readjustment
  • 24 VAC or 230 VAC power
  • Factory-fitted
  • Small footprint thanks to compact construction


Useful additions

  • TX silencer

-Suitable for EN/END controllers

– Casing in galvanised sheet steel

– Mineral wool lining conforming to DIN 4102, fire rating class A2, with RAL quality mark RAL-GZ 388, biodegradable as defined by TRGS 905 as       well as EU directive 97/69/EC

– Mineral wool faced with glass-fibre fabric providing protection against erosion by air flow up to a maximum air velocity of 20 m/s, inert to fungal         and bacterial growth

  • Air heater

– Suitable for EN/END controllers

– See leaflet 5/20/EN/... for dimensions and technical data


Construction features

  • Rectangular casing
  • Flanges on both sides, suitable for duct connection
  • Volume flow controllers from H = 400 mm are fitted with two damper blades and two volume flow rate scales
  • Acoustic cladding cannot be retrofitted
