Destratificator is one of the most efficient energy saving components. - details see: https://www.machineto.com/destratificator-vents-drf-10214371

Applications

Destratificators are used in industrial premises, workshops, exhibition, concert and enclosed sport halls and other premises with the ceiling height 5 m and more. As a result of natural air convection warm air is accumulated upwards closer to ceiling and air at 2-2.5 m height has lower temperature.

Description

Destratificators are designed for balancing of the air temperature under the ceiling and in occupied areas. A great amount of thermal energy is accumulated above the occupied areas and just dissipated through the walls or ceilings in case of no heat recovery. Destratificators solve this problem by generating vertical air flow that minimizes air temperature drop between floor and the ceiling. Use of destratificator reduces thermal losses and energy demands for heating.

Design

The destratificator casing is made of polymer-coated or galvanized steel and supplied with aluminium guiding nozzle.

Motor

Destratificator is equipped with a single-phase external rotor motor and a centrifugal impeller with backward curved blades. The motor has integrated overheating protection with automatic restart. The motors are equipped with ball bearings. Ingress protection rating is IP 44.

Speed control

Step or speed control is performed with a thyristor or autotransformer. Several destratificators can be connected to one speed controller if the total power and operating current do not exceed the rated speed controller parameters.

Mounting

Destratificators are designed for indoor mounting in premises protected against weather factors and are installed under ceiling with the discharge nozzles downwards. Electric power to the destratificator fan is supplied through the external terminal block. While connecting and installing the unit follow the installation guidelines and wiring diagram shown on the terminal box.

Selection

While selecting the standard size of the destratificator consider that the effective reach distance must be correlated with the premise height as 1, 25 to 1. The number of destratificators is selected on the assumption that the total air capacity is equal to the premise volume or doubles it.
