Type X-CUBE EX

ATEX (ATmosphères EXplosibles, or explosive atmospheres)

In certain locations or with certain conditions, even air can present a hazard. If flammable gases, mists or vapours, or combustible dusts mix under atmospheric conditions with air, an explosive atmosphere may result. In such a case it needs only a source of ignition, e.g a spark, friction, heat or electrostatic discharge, to cause an explosion, which in turn can result in loss of life, serious injuries and significant damage.

It is hence essential that equipment and systems intended for use in areas with potentially explosive atmospheres are designed and installed in such a way that the health and safety of people are not at risk.

Air handling units which are to be installed in areas with potentially explosive atmospheres, or which circulate potentially explosive air, have to meet special requirements; system owners, specialist consultants, HVAC contractors and manufacturers all have to ensure that these requirements are met.

The legally binding measures required to avoid hazards and to improve safety for people at risk from explosive atmospheres are stipulated in Directive 1999/92/EC (ATEX 137) for system owners and in Directive 2014/34/EU for manufacturers

EX

THE NEW TROX EXPLOSION-PROOF AIR HANDLING UNIT

X-CUBE Ex is a configurable, explosion-proof air handling unit for the conditioning and circulation of indoor air and process air, i.e. for the ventilation, filtering, heating and cooling of air in areas with potentially explosive atmospheres.

Construction and ATEX certification of TROX X-CUBE Ex air handling units meet the basic requirements of the so-called ATEX Directive 2014/34/EU, included harmonised standards (EN 1127-1:2011, EN 13463-1:2009, EN 13463-5:2011) and Guideline 02 of the German Association of AHU Manufacturers (Requirements on air handling units for use in potentially explosive atmospheres, as of August 2016). Conformity with the ATEX Directive requires the use of specially designed components. A notified body has examined and certified conformity with the basic safety and health requirements.

To ensure that the special requirements regarding implementation and maintenance of quality assurance systems for the manufacturing of explosion-proof units, devices and systems are met and that the products conform to the relevant standards, the manufacturing of TROX X-CUBE Ex air handling units is subject to the quality management measures of EN ISO IEC 80079-34. A notified body has examined and certified conformity with the quality management system.

TROX X-CUBE Ex air handling units are suitable for use in zone 1 and zone 2 areas with potentially explosive atmospheres. They also meet the requirements for group IIB of flammable gases and vapours, and temperature class T4.

  • Multileaf dampers and actuators
  • Filters
  • Fans
  • Explosion-proof inspection window
  • Surfaces and sound attenuators
ATEX-compliant, explosion-proof TROX multileaf dampers are available. Leakage class 2 or (optionally) 4 to EN 1751; low leakage brass bearings, stainless steel as an option. Multileaf dampers with linkage and opposed action blades. Multileaf dampers can be supplied with an ATEX-certified, explosion-proof spring return actuator with integral auxiliary switch.
Choice of ATEX-compliant pocket filters and Mini Pleat filter elements. Available filter classes from M5 to H13, depending on filter. ATEX-compliant Mini Pleat filters are fitted with a lightweight, anti-static plastic frame. Galvanised mounting frames are powder-coated; stainless steel is available as an option.
High-performance explosion-proof centrifugal fans for IEC standard motors; type of protection: flameproof enclosure Ex de. Construction according to equipment group II, equipment category 2G or 3G, group IIB of explosive materials, temperature class T4. Motor efficiency class IE2 (based on EU classification). PTC resistor for motor protection.
Square inspection window that meets the technical requirements of EN 13463-1. The size of the transparent window is at least 190 mm x 190 mm.
In addition to the powder-coated external surface, the internal skins of the X-CUBE Ex can be made of stainless steel. The mineral wool infill of attenuator splitters is covered with perforated sheet metal (option L); this prevents electrostatic discharge and also erosion.
