Nevada Wraparound1 Nevada Wraparound2 Nevada Wraparound3

The NEVADA range of direct drive air handling units provide two types of framework construction, either 'Wraparound' or 'Pentapost' to form a rigid construction for the unit and its components. Each type of unit is suitable for either internal or external mounting dependant upon application, with a selection of six standard models and a duty range of up to 1.4 m3/sec. Each NEVADA unit comprises a direct driven centrifugal fan, a pleated panel filter and a L.P.H.W. Coil or Electric Heater Battery as standard components.


  • Excellent performance characteristics with Air volumes of up to 1.4 m3/sec.
  • A quality construction air handling unit, competitively priced, providing value and reliability.
  • Standard components include forward curved double inlet fans, electric or hot water heaters and panel filters.
  • Flexibility in design with internal or external mounting units and a comprehensive range of accessories.
  • Slide rails allow installation and regular maintenance of standard components with minimal effort.
  • Single Unlined, Lined and Double skinned casings to meet required noise criteria.
  • Standard NEVADA 'Wraparound' units are available on a 48 Hr working day despatch.
  • Flexibility in performance with fully speed controllable fans.
  • A wide range of electric heater outputs are available.
  • Matching silencers are available to fit onto the outlet of the unit via a discharge spacer.
  • Fan, filter and heater all within one casing, therefore easier to install.

N.B. 48 Hr Despatch does not apply to Weatherproof or Non Standard Sizes

General
  • The standard range of NEVADA 'WRAPAROUND' units are manufactured from galvanised sheet steel, precision cut, then folded to standard sizes. Although units are galvanised casings as standard, they can be supplied with plastisol coated steel outer skins upon request.
  • Panels are flush mounted into the unit framework rebates on a crush resistant closed cell neoprene sealing gasket, which provides an air seal between the panel and the component section.
  • Gaskets are chemically and biologically inert and meet all requirements of DW 144 The NEVADA Wraparound can be used for external mounting, supplied with a weather louvre and fitted with water sheds over the top of the access panels to prevent water ingress, with plastisol coated steel outer skins as an option on the unit casing construction.
Single Skinned
  • Casings are manufactured from 1.0mm thick pre hot dipped galvanised mild steel suitably braced for rigidity. Access to the fan and filter compartments is via lift off access doors with quick release fasteners.
  • Panels are flush mounted into the unit framework rebates on a crush resistant closed cell neoprene sealing gasket, which provides an air seal between the panel and the component section. Gaskets are chemically and biologically inert and meet all requirements of DW 144.
  • Single Skinned Lined Casings are manufactured from 1.0mm thick pre hot dipped galvanised mild steel suitably braced for rigidity, internally lined with 25mm thick foam to building regulations class O fire propagation to BS 476 Part 6, spread of flame class 1 to BS 476 Part 7 and has a thermal transmittance U value of 1.92 W/m2 K.
  • Double Skinned Casings are manufactured from 1.0mm thick pre hot dipped galvanised mild steel suitably braced for rigidity, with an inner skin of 0.9mm hot dipped galvanised mild steel, enclosing 25mm of 65kg/m3 mineral wool. N.B. Fan access and filter removal is via side access panels.

The fans are mounted onto a diaphragm plate, are double inlet double width forward curved centrifugal, housed in a purpose designed scroll with integral deep drawn inlet cones to facilitate maximum efficiency. All fans are suitable for 230V/1Ph/50Hz or 60Hz electrical supply. The fans are suitable for operating temperatures of up to +40°C. The Motors are isolated from the unit case and have anti-vibration mounts fitted between the motor mounting arm and the fan casing. All wheels are dynamically balanced

  • Pleated Panel filters are 50 or 100mm deep disposable type to Grade G4, in accordance with BS EN 779: 2002. They are for side withdrawal, mounted into the unit on slide rails, which are manufactured from pregalvanised sheet steel to enable filter replacement.
  • Pleated Panel filters are manufactured from pleated media which consists of reinforced non-woven fibres, with expanded diamond grid to provide maximum support. Pleating the media effectively increases the filtration area to more than three times that of the face area, providing high dust holding capacity and low pressure loss. The pleat pack is encased in a water resistant lattice cardboard frame.
Hot Water Heating Coils (L.P.H.W.)

Coils are constructed from seamless drawn copper tube to BS 2871 mechanically expanded into aluminium fins with die formed self spacing collars. The coil casing is formed from heavy gauge galvanised sheet to BS 2989 to make a rigid assembly, with BSP(M) pipe fittings on coil flow and return connections. Tube end plates have die formed collared holes to allow expansion and contraction of the tubes without damage. All coils are subjected to an air under water test to 16 bar during manufacture. All coil sections are fitted into the units on pre-galvanised steel slide rails for ease of assembly and withdrawal.

(E.H.B)

Elements are constructed from Nichrome 5 spiral resistance wire surrounded by magnesium oxide powder and sheathed in stainless steel. The elements are mounted on a galvanized sheet steel terminal housing. All electric heaters are fitted with high temperature thermal cut out protection for wiring into the control circuit and are generally available in the power and number of steps required. A control system must be provided to ensure the heater is not activated when there is no airflow and the fan runs on after the heater has been switched off, to dissipate any residual heat. It is recommended that a fan run on timer be incorporated within the controls to prevent possible heat damage, as well as an airflow switch.
