Products Features
1. The system is concise.
Air conditioning system only contains outdoor unit, indoor supply and return air duct. Don`t need special room, water pumps, cooling towers, valves and other auxiliary equipment.
2. High efficiency and energy saving.
It use efficient thread copper pipes and hydrophilic aluminum fins mechanical expanded and patented circuits arrangement to ensure high thermal efficiency of heat exchanger. We choose high efficiency closed scroll compressor (or inverter compressor), partial load unload control. Fresh air in transition season no energy consumption cooling. Can adjust fresh air needed of ventilation system.
3. To prevent corrosion and rust.
Frame use electric galvanized sheets and again after electrostatic anticorrosion coating. It can adapt to the snow and rain exposure and other outdoor climate environment. The roof cover with special structure. It can effectively prevent leakage under rain and snow slanted stainless steel condensate drain pan, make condensate water drainage unobstructed.
4. Application is flexible.
The unit structure is compact and beautiful, there are 12 kinds of supply and return ways for the customer to choose, to facilitate on-site installation; Different function section can be set up according to the customer demand, reserve the access door for convenient maintenance.
5. Safe and reliable.
Unit selects the world famous brand of parts and components, to ensure high reliability and service life of the overall unit. Unit adopts industrial control system. It can make the unit is always under the best operation status, protect the function is all ready.
