Roof packaged Air conditioning Modules
With the continuing development in hermetic compressor technology and the introduction of environmentally friendlyg p p gy y yrefrigerants , roof packaged air conditioning is increasingly becoming the choice of both coach builder and trainoperator as the most convenient and cost effective method of providing air conditioning to passengers.
Sepand Tahvieh’range of roof package units is considerable with cooling capacities ranging from 15kw to a massive42kw.
RMP units can be used individually or in pairs to cover virtually all cooling requirements likely to be necessary toprovide luxurious air conditioning to passenger saloon areas. All Modules are ideal for both new vehicles and for retro-fit to existing cars. Their fully stainless steel construction combined with all copper heat exchanger coils makes themsuitable for the most arduous of climates.
Th f f ll h ti k th it i t ll i t f b t j h l T iThe use of fully hermetic compressors makes the unit virtually maintenance-free between major overhauls. Twincompressors employed within individual refrigeration circuits allows independent compressor operation underthermostatic control or in the unlikely event of compressor failure or refrigerant leakage.
Air filters are easily accessible from within the car and can be changed in seconds.
We offer another Sepand Tahvieh Co’ roof mounted A/C model which is so suitable for train set and LRV and any otherpassenger wagon which weight of A/C package is so important. TRS roof mounted unit is considerable with cooling
iti i f 28k t i 42kcapacities ranging from 28kw to a massive 42kw.
Advantages of TRS A/C unit:
- High reliability
- Totally self-contained, hermetically sealed system
- Environmentally friendly refrigerant
- A wide range of capacities offered within one low
profile design
- Easy installation and low maintenance
- Ideal solution for retrofit applications as well as new cars
Standard Features:
- Hermetic refrigeration circuits maximize reliability.
- Efficient scroll compressors offer greater reliability reduced power consumption and lower noise levelsEfficient scroll compressors offer greater reliability, reduced power consumption and lower noise levels.
- Features latest microprocessor control system. Readily adaptable to customer’s preferred refrigerant.
- KW for KW, the lightest air conditioning unit in the industry.
There is the other model which the air handling units with their fans,evaporators, heating batteries, and filters, are located in the roof area. Thecompressor and condenser can be installed underneath the car.compressor and condenser can be installed underneath the car.The air handling unit for roof installation has a particularly low profile in orderto lose as little ceiling height as possible. The fan (a silenced version) with 2radial impellers, evacuates the air and passes it via an evaporator and anelectric heating battery into the roof ducts.
The compressor unit forms the core of the refrigeration circuit. The compressor can be semi-hermetical or open,depending on the type of power supply. We only use proven series production units from well-known compressormanufactures, or in accordance with customer’s particular requirements. Under normal circumstances, thecompressor unit is fitted with a capacity control.p p yThe driving motor is supplied according to existing power supply and usually incorporates overload protection.The condenser robust axial fans refrigerant collecting vessels and filter dryers, complete with the special finnedheat exchangers. To facilitate cleaning of the heat exchangers, the fans and bottom plates can be swung asidewith a few easy hand movements.
Under FRAME Air Conditioning System
This system is formed of three individual sections which consist of Compressor section Condenser section and AirThis system is formed of three individual sections which consist of Compressor section, Condenser section and Airhandling section and connection of units is by units is by special pipes and flanges, therefore installation anddismounting of the system are easily possible.
All of the sections are under frame mounted.
This system operates in high ambient temperature up to +50 C with high condense temperature up to +65 C.
At this system has been used of refrigerant R 134a (recommended by international associations and for environmentalprotection) and using of this refrigerant is one of the advantages of this system in comparison of its foreign analogous(which has used of refrigerant R 12)
By using of very perfect and exact control
system Sepand Tahvieh Air conditioning
systems have ability of adjusting temperature
in each of compartments individually and by
selecting of passengers between 22 C to 26 C.
also the unit can operate in all seasons of year
in temperature range between 25 C to +50 Cin temperature range between -25 C to +50 C
for outside air.
According to customer order Sepand Tahviehg p
control system could be delivered as
microprocessor systems and PLC.
Driver’s Cab Air Conditioning Systems
With locomotive operators’ increasing efforts toimprove drivers’ environmental conditions and , inconsequence, reduce fatigue symptoms, AirConditioning of Drivers’ Cabs has become agnormal factor to ensure both clean, fresh air atthe right temperature.
Sepand Tahvieh range of Cab Air Conditioners havebeen designed to meet a wide range of operators’requirements and environmental conditions.
L ti St ti I t Ai diti i S tLocomotive Static Inverter Air conditioning System :
This Air conditioning System is designed and manufactured for producing of standard and suitable temperature of Locomotive static inverter. p
This system consist two main unit one out door unit which isinstalled on the roof of locomotive and the other indoorinstalled on the roof of locomotive and the other indoorunit which is installed in the locomotive and on theinverter.
In manufacturing of all systems we use special equipments for security of passenger s and units in cooling and heatingg y y g g g
modes.
Sepand Tahvieh uses of good quality equipments with high credit brands from well-known European and Western
sources. For example compressor from Bitzer (Germany) and Maneurope (France) and Valves from Danfoss (Denmark)
and Alco (U.S.A).
Sepand Tahvieh Co. as up to 10 years study, design and manufacturing
Rolling stock A/C systems is up to date of knowledge of designing and
manufacturing.
We use the suitable software for calculation of heating and cooling
loads and designs of equipments and also designs of structure, FEA
modeling sheet metal design thermal system performance andmodeling, sheet metal design, thermal system performance and
balancing.
AUTOMATIC SHUT ON-OFF TOILET SYSTEM
Also Sepand Tahvieh has good activities in Environmental Engineering and also it can deliver suitable and economic toiletsystem for passenger coachessystem for passenger coaches.
Not only AUTOMATIC SHUT ON-OFF TOILET SYSTEM is according Rolling Stock Standard and with good technicalspecifications but also it is so economic and suitable for any passenger wagon without toilet system.
