Description
Along with the light cream colour, the flat top and compact design give an aesthetic and neat appearance when installed in the line of sight. The durable powder-coated sheet metal and corrosion-resistant fixings make the Daikin Rooftop Packaged units ideal for the harsh Australian climate.
Standard Features:
The base beams are set to have a rigid base for the whole unit. The beam includes forklift slots and rigging holes for easy handling. It is also constructed to allow mounting on a roof curb, and the dimensions of the roof curb should be strictly followed in compliance with the installation manual.
All Rooftop Packaged units utilise a belt/pulley driven supply air fan, with a variable pitch pulley to enable a wide range of supply air volumes and external static pressures to be met. Furthermore, where required, the supply air fan motors, pulleys and belts can be upgraded easily on-site.
- Convertible Return and Air Supply –
The Unit can be easily converted from horizontal to vertical (downward) supply and return air duct configuration by relocating the panels and supply air fan mounting.
- Powder Coated Condensate Drain Pan –
The sheet metal condensate drain pan is powder-coated for corrosion resistance.
A 50mm filter slot is provided as standard instances where a field-supplied filter is required.
Technology
Condenser Fan and Motor
Daikin Rooftop Package Units use propeller type Condenser Fan and Motor Fans, direct driven by weatherproof electrical induction motors. Condenser fan motors have class F insulation and splash-proof enclosures.
Condenser and Evaporator
The condenser and evaporator coils are manufactured from seamless inner grooved copper tubes mechanically bonded to aluminium fins for optimum heat transfer. All coils are Nitrogen pressure tested to 4.2 MPa and are further leak tested with Helium at 1.6 MPa. To improve their corrosion resistance, a Hydrophilic Gold Fin is provided as standard.
Casing / Structure
The UAYQ-C series casing is made of zinc coated galvanized steel sheets which are powder coated to provide a durable weather resistant finish to withstand the harsh Australian climate and provide minimal visual impact when installed in line of sight. All fasteners are zinc plated for corrosion resistance and superior durability.
Insulation
To prevent the likelihood of condensation forming inside the casing, Daikin Rooftop Packaged Units are equipped with 10mm Polyethylene panel insulation throughout.
Evaporator Fan and Drive
Daikin Rooftop Packaged Units use a belt driven, double width double inlet (DWDI) centrifugal forward curved evaporator fan. In conjunction with the factory fitted Variable Pitch Pulley (VPP), this evaporator fan allows the unit to deliver a wide range of airflows and external static pressures.
Expansion Device
For precise control of refrigerant flow, the UAYQ-C series is equipped with an Electronic Expansion Valve (EEV).
Compressor
Compressor used in UAYQ-C series Packaged Units are hermetically sealed scroll type. All compressors are fitted with an internal overload protection to protect your investment.
