Active airflow management

Ventilation Units

Active Doors

FANS

Used to force airflow through a rack where ventilation unit is not used.

  • Possible to install:
    • a) on side or top of wall-mounting rack - special perforation needed, ordering code of the wall mounting rack to be extended: VH for 2x side perforation or –TH for 2x top cover perforation)
    • b) in top or bottom frame of distribution rack - requires perforated gland plate DP-VE-ROV2 or DP-VE-ROV4
  • Mounting kit included
  • Code: DP-VE-01

Features

VENTILATION UNITS

Ventillation units are used to enhance  airflow for improved cooling of equipment installed in racks. Ventillation units are mounted on 19" vertical holding rails (in vertical position) or in top or bottom frame of the rack.

  • Two to nine fans
  • Possible to install:
    • a) in 19" extrusions - horizontally
    • b) in top or bottom frame of free-standing rack
  • Connecting kit for ventilation unit is needed when installing in top or bottom frame
  • Temperature range -10°C to 55°C
  • Thermostat in the range 0°C - 60°C included; optionally no thermostat
  • Voltage range 230V/50Hz (optionally 48V DC)
  • Protection category to EN 60 529 IP 20
  • Color powder coated RAL (standard RAL 9005)
  • Enhanced option: DP-VEN-xx-E

 

ACTIVE DOOR

The active door is designed for mounting of up to 3 ventilation units, each with 6 fans (for racks of 600mm width) and 9 fans (for racks of 800mm width). Front mounted active door ensures effective air delivery into the rack. The rear mounted active door removes heated air from the rack. Active doors can be where higher density heat loads are required by augmenting the delivery or extraction of air for cooling purposes.

  • Perforated sheet metal or vented door
  • Preparation for mounting of 3 ventilation units, each with 6 fans
  • Multipoint swivel handle lock
  • Universal keys
  • Colour design - powdered paint RAL 7035 or RAL 9005

 

Apply the appropriate codes in positions describing door type/door locktype in the rack ordering matrix:

  • JW for sheet steel perforated door, ready for up to 3 x 6 (3 x 9)-position ventilation unit, multipoint swivel handle lock, universal key
  • KW for vented door, ready for up to 3 x 6 (3 x 9)-position ventilation unit, multipoint swivel handle lock, universal key

Applications

The EC technology fan-motors provide a modern high-end air-flow management solution that improves efficiency of the air condition with the aim to reduce the power consumption.

Efficient, ecological, economical!

New high quality fans feature electronically commuted synchronic motors, well known as "EC motors“. The main advantage of this technology is a very low power consumption in comparison to the standard AC motors. For example – power consumption of our new DP-VEC ventilation unit is seven times lower then the standard DP-VEN with equal air-flow. On the top of it, DP-VEC provides up to 60% bigger air-flow with an equal number of fans and required air pressure in comparison with the standard DP-VEN.
