Central Station Air Handler

1,188 to 39,600 m³/h
700 to 23,308 cfm

  • Chilled water, DX and hot water coils
  • Wide range of coil sizes
  • Forward curved, backward curved and airfoil fan

Features

  • Units are design in accordance with ARI Standard for coils (ARI 410).
  • Double wall with 1” & 2” 40kg/m³ CFC-Free PU insulation (HCFC 141b). Isolates insulation exposure to the air stream.
  • Wide range of coil offering – 4, 5, 6, 7, 8 rows and 8, 10, 12, 14 FPI for chilled water. Optimized coil circuiting. DX Coil (4, 6 rows) and Hot Water Coil (1, 2 rows) are also available.
  • All chilled water, DX and Hot Water coils are factory pressure tested at 400 psig as standard.
  • Coil tracks enable easy coil removal for complete cleaning and assurance of a dry unit interior.
  • Powder painted sloped galvanized steel drain pan with bottom drainage.
  • Stainless steel marine double drain pan provides positive drainage under pitch and roll conditions.
  • Forward curved, Backward curved and Airfoil fan.
    • Forward curved – sizes 160 to 1000mm diameter.
    • Backward curved / Airfoil blade – sizes 225 to 1000mm diameter.
  • Low leak construction with hex socket compression, type latch and nitrile gasket on mating panel parameter.
  • Factory installed unit base of 100mm height, constructed of 14 gauge galvanized steel.

50mm Non-Thermal Bridge (NTB) Features

  • Composite Corner Piece (Trileg) – ABS material.
  • Non-Thermal Bridge (NTB) Aluminum frame extrusion.
  • Non-Thermal Bridge (NTB) sandwiched panels and access doors.
  • Non-Thermal Bridge (NTB) quality panel to frame fitting.
  • No condensation problems in humid environment at low internal temperatures.
  • Rigid construction with aluminum frame work and machine-injected rigid polyurethane foam panels.
  • Spring mounted fans for low vibration transmission.

Standard Options

  • Compression latch (hex socket): Only requires the use of hexagon wrench to open / close the access door.
  • Chilled water coil with steel header: Coils are of aluminum/copper plate fins with belled collars and bonded to 12.7mm OD copper tubes by mechanically expansion. The coils have l i d galvanized steel casing and steel headers with male threaded connections.
  • Direct expansion coil (DX coil): Coils are aluminum/copper with belled collars and bonded 12.7mm OD copper tubes by mechanically expansion. Coil are provided with brass distributors with sweat type connections.
  • Spring isolator: As standard from the factory the fan and motor assembly are mounted on a common base with color-coded internally mounted spring isolators, which saves site installation cost.
  • Assembly fan housing motor and base: FMB are made of painted heavy gauge mild steel (for fan size 450 and above) or power strut type (for fan size 160 to 400) to ensure proper and easy installation fan housing and motor.
  • Bearing arm: Self aligning double row ball bearings mounted within a cost iron housing supported on tubular bearing arm assembly.
  • Taper lock pulley: Ability to change diameter of pulley according to fan shaft. Pulleys with taper lock bush allows for convenient dismantling and maintenance of drive package, besides offering flexibility in interchanging for different shaft sizes.
  • Fan discharge collar: Flanged discharge collar to provide easy ducting connection.
  • Handle grab: Large and non-conductive handles for easy panel removal.
  • Accessory high velocity filter (HVF) frame: For “free air return” application, factory supplied 75mm HVF track is an option instead of one module casing resulting in shorter overall unit length.
  • Dampers: Mixing boxes are equipped with opposed blades interconnected outside with return air dampers.
