Smoke Control Systems

Specific Control Functions

Our fan technology plays several important roles in the event of an emergency condition. Each could be an important defense against life-threatening fumes and hot smoke:

Control and removal of hot smoke/gases to give time for occupants to escape – even if the fan itself is subject to high temperatures. Extraction of ‘cool’ smoke while it remains unstable in the early stages of a fire.

Pressurization: supply of clean air into escape routes to hold back smoke.

Clearance: removal of residual smoke after fire is contained and suppressed Natural ventilation may be inadequate for these needs, particularly where ‘cool’ smoke may be involved, and could be compromised by prevailing winds.

Sizes: 315mm to 2800mm Ø
Volume flow: up to 210m3/s
Static pressure: up to 2070 Pa
High temperature capability:
Up to 400°C for 2 hours
IE2 motors where applicable
Role: Emergency ventilation/hot fire smoke extraction

Design Features

The Ventrite Fire Mac Smoke Fans are currently fitted into Drying Machines, Stenters, and Smoke Venting systems, all over the world. This long experience coupled with the introduction of the new improved performance JM Aerofoil fan range forms the basis for the new H.T. SERIES fans and roof extract units designed specifically for Fire Smoke Ventilation. Our suppliers manufactures fan motors, and is therefore able to look critically at the requirements of motor insulation, bearings and lubricants which are vital elements in achieving high temperature performance. Extensive stress tests on the new JM Aerofoil fan impellers operating at high temperatures has enabled Ventrite International to make the best use of both designs and materials.

A full high temperature test programme has been successfully completed. Some of this programme was carried out at independent laboratories, eg T.Ü. in Germany and C.T.I.C.M. in France

These tests combined with renowned high standard of engineering and quality assurance serve to support the H.T. SERIES specification.

Extensive market research has resulted in the H.T. SERIES being offered in six temperature/time categories to meet all of the internationally recognised requirements.
