Convenient for unit selection- Colour selectionIn order to satisfy the needs of different building style, the frame & panel can be ordered in either white or dark grey colors.- Wide cooling capacity rangeThere is a large production line of packaged units, with capacities ranging from 3Ton to 110Ton(12kWto 392kW)at nominal conditions.It is suitable for installation in rooftop or ground.- Panels selectionPanels can be constructed of galvanized steel coated (Standard) or Panels are double-skin with injection of high density polyurethane.- Optional accessories•Tropical climate T3 condition•Economizer with return air, fresh air dampers & rainproof cowl•Free cooling function for low ambient temperature•Additional water heating coil or Additional electric heaterfor heatingor dehumidification•Optional supply / return air configuration (Side/Top/Bottom)•Optional high level filter (G4 panel type filter, F8 bag type filerand H13 HEPA filteretc)•Optional golden condenser & evaporator for some area need special anti-corrosion•Optional precision temperature & humidity control•Heat recovery(Plate type heat recovery & Wheel type heat recovery optional)• 100% Full fresh air• High external pressure, long air supply distance. EC Plug Fan.2. Outstanding reliability- EconomySome models feature the flexibility and economy of 2~4 stages operation. Compressors are progressively switched on only as they are needed. This has the added advantage of lowering start-up current.- Durable construction•Standard cabinets are constructed from high grade galvanized steelwith polyester powder coated, they are completely weatherized for outdoor installation.•Coils are manufactured from seamless copper tubes mechanically expanded intohydrophilicaluminum fins, they are tested under 450 Psiat the factory to avoid leakage. They also undergo dry chemical cleaning after manufacturing for optimum system cleanness.•External fasteners are stainless steel or galvanized type. Corrosion resistant drain trays are also included.•All units are tested at the factory to make sure no leakage and provide reliable start up.- Reliable scroll compressorHigh efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater. Famous brand compressor: Copeland, Panasonicand Danfoss. More reliable.- Multi-protection design•Electric panel consists of breakers and contactors for compressors, condenser & evaporator fan motors, phase sequence relay and other necessary protection devices for the main components.•Main power supply breaker is optional.•All electric parts are Schneider Electric brand.3. Quieter operation•Compressors and low noiseSupply fan are mounted on rubber vibration dampers.•Wave type acoustic Insulation for compressor section, thermal insulation for coil and fan section.4. Easy installation & maintenance•All units are factory assembled, internally wired, fully charged refrigerant.•The Rooftopshas provisions for forklift and crane lifting. On arrival to the job site they are ready to be lifted to their operating position through the lifting supports available on the units. only connect the wires of power supply, and no need to connect any signal wires.•Quick release fasteners or removable the access doors on the compressor, fan motor, filter, and electric box sections, provide convenient access to system components for maintenance and service.•The unit provides external pressure gauge for convenient and fast checking system pressure without removing the panel.•If the unit is in running with abnormal operation, the controller will show the error codefor easy troubleshooting.•Standard washable filter, easy toclean.5. Control system•The unit is completely factory-wired with necessary controls and terminal block for power wiring.•SYSLAB wired controller issupplied with unit controls as standard.The precision control makes all heating, cooling, or ventilating decisions in response to electronic signals from sensors measuringindoor and outdoor temperatures.•Besides standard SYSLAB wired controller, SIEMENS & CAREL PLC controller with BMS function and precision temperature & humidity control can be matched as optional solution.SpecificationsModelSRT-ST1H12ASRT-ST1H15ASRT-ST1H20ASRT-ST1H25ASRT-ST1H30ASRT-ST1H35ACoolingCapacityTon3.44.35.06.98.710.2kW12.015.217.524.030.335.6Power InputkW4.15.35.58.811.312.3Running CurrentA7.49.710.216.121.223.3HeatingCapacitykW13.216.618.426.533.337.7Power InputkW3.84.85.18.210.411.3Running CurrentA6.99.29.715.120.122.2Power Supply380~415V/3Ph/50HzRefrigerant & Charging QuantityTypeR410aKg3.13.14.32x3.12x3.12x4.3CompressorType/ScrollBrand/CopelandCopelandCopelandCopelandCopelandCopelandCompressor/CircuitNos.111222Energy Adjustment%0,100%0,50%,100%CondenserSectionCondenserTypeCopper Pipe + Anticorrosion Aluminium FinCondenser FanTypeAxial / DirectQty111111Power InputkW0.250.370.370.550.750.75Airflowm3/h46007800780090001260012600EvaporatorSectionEvaporatorTypeCopper Pipe + Anticorrosion Aluminium FinEvaporator FanTypeDirectDirectDirectBelt-DrivenPower InputkW0.320.370.451.11.52.2Supply Airflowm3/h210026003400410052006300CFM123515292000241230593706ESPPa100100100200200250FilterStandardTypeG4 Panel Type FilterSound LeveldB(A)676768717272DimensionLengthmm149814981498197819781978Widthmm110011001100117511751175Heightmm109510951095109510951095Net WeightKg245260290420485500*** *** ***ModelSRT-ST1H45ASRT-ST1H50ASRT-ST1H60ASRT-ST1H70ASRT-ST1H90ASRT-ST1H100ACoolingCapacityTon12.714.317.120.025.730.0kW44.550.060.070.090.0105.0Power InputkW17.019.522.826.732.939.7Running CurrentA31.735.639.948.361.070.6HeatingCapacitykW48.754.364.075.496.2113.2Power InputkW15.618.021.024.830.436.7Running CurrentA29.933.537.545.457.366.3Power Supply380~415V/3Ph/50HzRefrigerant & Charging QuantityTypeR410aKg4.3+8.54.3+8.52x7.52x8.53x7.53x8.5CompressorType/ScrollBrand/CopelandCopelandCopelandCopelandCopelandCopelandCompressor/CircuitNos.2/22/22/22/23/33/3Energy Adjustment%0,50%,100%0,33%,66%,100%CondenserSectionCondenserTypeCopper Pipe + Anticorrosion Aluminium FinCondenser FanTypeAxial / DirectQty111122Power InputkW1.11.51.52.22x1.12x1.5Airflowm3/h165002100021000270002x165002x21000EvaporatorSectionEvaporatorTypeCopper Pipe + Anticorrosion Aluminium FinEvaporator FanTypeBelt-DrivenPower InputkW33445.55.5Supply Airflowm3/h7600850010900125001600019500CFM4471500064127353941211471ESPPa250250300300300300FilterStandardTypeG4 Panel Type FilterSound LeveldB(A)737373747475DimensionLengthmm226822682298229828782878Widthmm147014701650165021402140Heightmm116711671400140019641964Net WeightKg75077083086011501350WorkshopProduction LineProject ReferenceWe can provide ODM & OEM manufacturing service for customers all over the world, our promise is: ''Tell us what you need and we will work with you to deliver.''To know more about us, please feel free to contact us and sincerely welcome to visit our factory at your convenience.
