Dynamic smoke exhaust ventilators with high thermal efficiency enclosure
Dynamic ventilators with high thermal performance enclosure, completely airtight and hermetic, with thermal break and motorised opening. Equipped with roof extractor for smoke evacuation in case of fire 400 ºC/2h and 300 ºC/2h.
Enclosure: • Construction completely free of thermal bridges. • 60 mm thick refrigerated sandwich panel sides made of two pre-coated steel sheets on the outside and inside with a high-density polyurethane (PUR) core. • 60 mm thick cover filled with high-density polyurethane (PUR), made of galvanised sheet metal and coated on the outside. • Adapter socket (or skirting) for correct and easy installation on the roof. • Air permeability CLASS 4 (UNE-EN 12207). • Impermeability against driving rain CLASS E 1350 (UNE-EN 12208). • Resistance to high wind load. • Thermal resistance of the assembly less than 0.39 W/m2·K.
Opening system: • Motorised opening arm, with encapsulated IP65 mechanism. • Supply voltage at 230 V AC 50/60 Hz. • System reinforced and guaranteed with more than 20,000 cycles. • Limit switches in both positions (open and closed). • Snow load SL 1000. • Automatic opening by external signal from the control system (fire panel, smoke detector ...). Control systems not included in the equipment.
Fan: • An extremely robust structure that is able to withstand severe weather changes. • Maintenance switches for actuator and fan disconnection with auxiliary contacts. • Approved as a whole in accordance with standard EN 12101-3. • Tubular casing in sheet steel with polyester resin anti-corrosive treatment. • Adjustable cast aluminum impeller. • Shielded power cable with EMC protection.
Motor: • Class H motors for S1 continuous operation and S2 emergency use. With ball bearings and IP55 protection. • IE3 efficiency motors. • Three-phase 230/400 V 50 Hz (up to 3 kW) and 400/690 V 50 Hz (powers greater than 3 kW). • Maximum temperature of air to be carried: S1 -25 ºC +40 ºC continuous service, also suitable for warm climates with temperatures up to 50 ºC. S2 operation, 300 ºC/2h, 400 ºC/2h. • Motors can be regulated by frequency inverter, even in an emergency.
Finish: • Anti-corrosion cover made of galvanised sheet steel coated in RAL 7015. • Aluminium profiles RAL 7015. • Side panels RAL 7015.
On request: • Motorised opening arm with supply voltage of 24 V DC. • Exterior coated in any colour from the RAL chart. • Customised finishes.
