HELM ORION VENTILATOR

 

Helm has always been a solutions-led company and is well-positioned at the forefront of industrial progression. The company is therefore continually involved in finding effective solutions to smoke control problems.

​

Our natural smoke and heat exhaust ventilation systems are designed to extract smoke from the interior of a building through automatically operable roof-mounted ventilators, in compliance with Part 2 of the EN 1210 I code. Helm also installs powered smoke and heat exhaust systems to enhance ventilation. These systems not only ensure that fans and cabling comply with the relevant part of the EN 1210 I code but also ensures the company's research and development objectives are on par with the latest international developments.

 

Features

  • Natural day-to-day ventilation

  • Natural smoke exhaust in case of fire

  • No fan power consumption required

  • Compliance with the EN 12101-2

  • CE certified, for all the options

 

The Orion is a multifunctional roof ventilator with a certified aerodynamic area as a standalone ventilator with the certification extending when incorporating bird screens, burglar bars and wind baffles in any combination. The added advantage of the Orion is its compliance with EN 12101-2 and CE mark, allowing the designer complete peace of mind when specifying this product.

LOUVRES

 

Helm’s Louvres are designed to operate in conjunction with either mechanically powered or natural ventilators, to replace hot stale air in desired areas. Fixed Louvres provide permanent ventilation, whereas adjustable louvers louvres can be set to deliver a variable amount of air depending on the day-to-day climatic conditions.

​

All units are available in Galvanised, Zinc-Aluminium, Stainless Steel and Pre-painted material. On request, Aluminium can be used to manufacture certain products.

 

Testing facilities include a low-pressure wind tunnel, as well as a rain testing facility, both of which were designed for South Africa’s harsh conditions in conjunction with the CSIR and SABS.
