SAKURA Packaged Roof-top Unit - New SPEA Series launched
|
|
Packaged Roof-top Unit has been expanding its distribution root rapidly
for its high quality since its introduction to the market places so far.
Reflecting such favorable reputation on current SPRT series, Sakura is
now releasing new SPEA series to fit better for the needs of customers.
Basic design concept of the new series is almost same as the current series
while Optional Parts is further expanded to meet wide range requirements
on the following points.
1. Air filter with frame is not included as standard parts
As a matter of facts, most of Roof-top Package unit have a filter at
return
Air Grill inside the room for easier service, so it should be optional.
2. Sight glass, filter drier, solenoid valve excluded from
standard parts
---These parts are needed for Split System to be placed in the installation
---pipe line to protect system from improper installation while Package unit
---is completed in factory, before shipment, in full charge mode. This is
a
---reason why it should be put to each unit.
3. Magnetic contactor and overload relay for fan are not
included as standard parts
---Normally, the outdoor Fan Motor is only of 1 HP with internal protection
---to run when the compressor is running, For this reason, it is not
---necessary to have this Contactor with much complicated function to
---operate in the unit and put it aside as an optional parts.
4. Controller is an ordinary wall pad type and not PLC type
---For ordinary Cooling-only, or Heat Pump, a Wall Pad type Controller is
---used as a standard type. For more complex function, like Hot Water
---Coil, Electric Heater or with Humidifier function, however, need to use
---PLCtype Controller, to meet such functional requirement.
5. Insulation for indoor side is PE foam of 15mm thick
---This is a normal insulation thickness for PE form type to be effective
---enough for this Roof Top Package unit. On the other hand, 25mm thick
---PE foam is required recently in some project so that we will have to
---fulfill such need..
