6.2-45 Ton Rooftop Package Unit
Product Detail
Wide Operation Range
operate from 16°C to 52°C in cooling mode and from-10°C to 24° C in heating mode.
Standard Cooling only model operate from 16°C to 52°C, low ambient kit can be added to make the unit operatefrom-15°Cto 52°C.
High Efficiency DC Inverter Compressor Reliability
DC inverter compressor utilizes the permanent magnet motor technology which significantly enhances its overall performance and efficiency. At complete stop of the compressor, the magnets will position the rotor into the optimum position for a low torque start.
Multiple Compressor
By cycling off compressor operation to match building load, no energy is being wasted when room load requires lesser cooling capacity. No total shut down when servicing or repairing a faulty compressor.
Environmentally Friendly Refrigerant
uses the environmentally friendly refrigerant, standard with R410A in each system. Zero ozone depletion potential. Optional with R32 new refrigerant gas.
Casing
Constructed from heavy gauge galvanized steel. Panels are painted with epoxy powder paint for excellent finish, weatherability and corrosion resistance. Evaporator section is insulated with closed cell Polyethylene (PE) foam
Safety Control
High-low pressure cutout to protect compressor from high discharge pressure and system leakage.
Automatic Adjustment of Throttling
Electronic expansion valve adjusts the opening degree automatically .It makes sure that the system parameters are within a reasonable range when the unit operates under all working conditions, to improve the operation reliability and service life of the unit.
High Efficient Condenser Coil
Staggered row of inner groove tubes with 25 to 30% more surface area guarantee better heat transfer. Mechanically expanded into die-formed corrugated aluminum louver fins with increase the heat exchange surface which is high heat exchange efficiency. Leak and pressure tested to 650 psig.
Fully Leak Tested Refrigerant Circuit
Compressors, condenser coil, filter drier, thermo-expansion valve, distributor and evaporator coil is brazed in complete sealed loop. Leak and pressure tested at 650 psig. Pressure ports are provided on the discharge and suction line. Evacuated, dehydrated and charge with refrigerant gas priorto shipment.
High ESP Design
The external static pressure (ESP) range is from 80Pa~430Pa, which ensures the longer delivery distance for the air and provide the powerful cooling.
Design flexibility
Vertical side-discharge structure design.Flanges of air flow inlet and outlet as standard.It is suitable for installation on rooftop and ground.
Easy Maintenance
The unit provides external pressure gauge ports for convenient and fast checking system pressure without removing the panel. (Only for 7.5Ton-15Ton)
Easy Access Doors Design
Removable the access doors on the filter, fan motor, and electric box sections. Provide convenient access to system components for mainenance and service.
Controllers
Factory mounted thermostat as standard, can be unit mounted or remoted controlled(within 30M as standard, consult ZERO Eng. Team if longer distance is required. Other brand thermostat can be matched as optional solution. Centralized control function can be achieved through the centralized controller as optional.
Application
Office buildings, shopping malls, large conference centers, gymnasiums, exhibition centers, theaters
