The unit use modular design, each independent modular can be combined by micro computer to central control. The unit can also stop some modular based on its cooling condition to save energy and extend use life. The unit can produce heat capacity bellow -10 centigrade, and the heat capacity is 3 times than other electric heater, which is more suitable to use in winter season.
The unit can combine with fan, cabinet type air conditioner and suspending ceiling air conditioner to be Semi-central air conditioning system.
Flexible and easily installation
Each modular has independent frame, cooling system, protection system and step adjustment. One of the system's failure will not influence other system. The unit can combine the same modular to get required cooling system. The installation of each modular could be close to each other or have some distance, no need special space. The user only need to connect inlet/outlet water pipe, make sure water source and pump is clean, connect with electric power then the machine can work now.
Stable and reliable quality
The key components of cooling system are use branded products, such as SIEMENSE, LG, EMERSON, BILTZER and etc. Micro computer has smart defrost, fault diagnosis, capacity control, Antifreeze monitoring and other automatic control function to make sure the unit runs stable. The unit also has multiple protection to have double protection.
Smart control, high energy saving
The unit use modular design, and can start from low level to decrease the impact to power grid and save energy. Micro computer can sense system load automatically, and it can adjust power input to make sure the cooling capacity and heating capacity is needed.
The unit is use high efficiency enclosed scroll compressor with low noise, small vibration and high EER. We use high efficiency threaded condenser and evaporator, total heat exchange is 30% higher than other heat exchanger. Adopting anti-corrosion Hydrophilic aluminium fin which can work under bad weather. The heat-transferring coil is V type or W type to make sure the unit has a excellent heat exchange and defrost.
All the machines are after 100% special testing before shipping.
