Specialist Applications - Ventilation Products Overview

Rendovent - Heat Recovery Unit

This unit has a heat recovery system and is ideal for winter ventilation in polluted buildings where ventilation remains essential. The punka type discharge nozzles have long throw characteristics to ensure good air mixing at high level to protect workers against drafts. It is of plug and play design so modules can be installed over a complete large area to ensure good economic ventilation.
The unit is commonly specified for large workshops where welding or other fumes are present in the general air flow and dilution ventilation is required to maintain a healthy environment.

MLS - Horizontal Wall Louvres

A range of press formed and extruded aluminium wall louvres. These fixed and operable louvres are used for air inlet for natural or mechanical ventilation systems.
Also suitable for special purpose applications.

UNILAB MK1V - Vertical Wall Louvre

High Capacity Natural ventilation units with labyrinth blades to minimise water penetration. Used mostly in conjunction with large Industrial ventilation systems as a weather protected air inlet for mechanical or natural extract systems.
Also suitable for special purpose applications

NKVD-PF - Twin Flap Flat Profile Roof Ventilator

Rated as an approved Smoke Extract / Fire Ventilator.
A high capacity smoke extract ventilator with two flaps each operated by a linear pneumatic or electric actuator.
Available with a range of solid or glazed panel inserts to provide very high levels of insulation or sealing when required.
Bases are available in single skin aluminium, insulated construction or thermally broken and insulated construction.
Typical Applications: Generally specified for use on built up and cladded roof constructions where they are mounted on a suitable builders work up-stand.
The units provide a large free ventilation area to minimise the total number required.
Glazed units are not normally specified on flat roofs or where the roof slope is less than 5 degrees as inadequate drainage causes mould build up over time.
Also suitable for daily ventilation and special purpose applications.

NKVD-PS - Twin Flap Roof Ventilator with Sloping Flap Panels

Rated as an approved Smoke Extract / Fire Ventilator.
This unit is identical to the NKVD-PF unit except that the top flaps are sloping.
This improves water shedding and prevents water pooling when installed on Flat roof constructions.
Typical applications: As for the NKVD-PS but specified where high rainfall is expected or where the ventilator is on a flat roof with glazed insert panels, to improve drainage and minimise build up of deposits on the glass.
Also suitable for daily ventilation.

NKV-G - Horizontal Wall Louvres

This is a new range of low cost units designed to fulfil the needs of the building industry.
The Domelight is a fixed closed unit intended for daylight transmission only.
The Ventlight is similar but has an opening top panel that can be fitted with a pneumatic or electric actuator to open and close for daily ventilation purposes.
The Smokelight is an approved Smoke Extract / Fire Ventilator.
It is at present only available with pneumatic actuation.

TSL-V - Vertical Wall Louvre

High Capacity Natural ventilation units with labyrinth blades to minimise water penetration. Used mostly in conjunction with large Industrial ventilation systems as a weather protected air inlet for mechanical or natural extract systems.
Also suitable for special purpose applications
