Amrta rooftop air conditioners of RTU series are large and medium sized ones which are of full air system and possess the function of refrigeration, heating and ventilation. The air conditioners are characterized by high efficiency, energy conservation matured technology, integrated compact structure, stable an reliable performance an simple cycle. Besides, it's easy to install. They are widely used in mechanical, chemical and electronic and other industrial sites and places requiring comfortable air environment such as department store, supermarket and meeting room thanks to their compact structure and the suitability for integral installment to save useful space. The Rooftop Air Conditioner of RTU series are classified into 5 series of Free Cooling Rooftop Packaged, Explosion Proof Rooftop Packaged, Rooftop Packaged Unit with Hot Water Coil, Rooftop Packaged Unit With Gas Burner and Tent Packaged Unit. There are two types--cooling only and heat pump.
● Wide choice of communication interfaces
Heating Possibilities
Electric heater
The electric heater comprises of shielded resistance heaters, which are smooth stainless steel tubes 6 W/cm2 capacity. High temperature limit control offers overload protection and is set to 90°C and located at less than 150mm after electric heaters. This is provided as a standard feature on the electric heater, with the electric power supply cables made of reticulated silicon rubber, resistant to temperatures up to 200°C. For any rooftop unit size, three sizes of electric heater are
available, S (standard), M (Medium) and H (high).
Hot water coil
Hot water coils offer fully modulating control through the use of a 3 way valve. The hot water coil, connections and valves are all tested at pressure of 15 bars.
Frost protection is provided by forcing the opening the 3 way valve when supply temperature from hot water coil falls below 8°C and by stopping the outdoor fan when that supply temperature falls below 6°C. In addition to that, the 3 way valve is also opened at 10% value if the outdoor temperature falls below an adjustable value.
Hot water coils are always factory fitted, wired and fully tested, prior to shipment.
