FUJI Electric AQUA & HVAC

The newly released FRENIC-HVAC and FRENIC-AQUA are the first slim-type inverters specialized in energy-saving from Fuji Electric. These units have been produced as specialized equipment loaded with the standard functions required to independently operate fans and pumps in air-conditioning equipment and water treatment systems. The slim design allows the units to be mounted against a wall, like mainstream products sold in the Asian and European market. Moreover, all models are equipped with a built-in electromagnetic compatibility (EMC) filter for ensuring low noise.

 

 

 

 

 

The FRENIC HVAC series is the dedicated inverter for HVAC that features functions and performances offer the optimal thermal environment for the people working in the building by keeping the energy consumption in various devices (compressor, condenser water pump, AHU and others) to the minimum.

Fuji Electric contributes largely to global environment by realizing carbon dioxide reduction with energy saving by the inverter.
 
Wide variation in model capacity

Model can be selected from two model types.

- Standard type (EMC filter built-in type)
0.75 to 710kW (Protective structure IP21 or IP55 can be selected with the model between 0.75 and 90kW.)

 

Inverter capacity EMC filter DC reactor Protective structure
0.75kW to 90kW Built-in Built-in IP21/IP55
110kW to 710kW Built-in External IP00

 

* The models with inverter capacity 45kW to 710kW are coming soon.

• User friendly, useful key pad

Wet-bulb temperature presumption control
This function is optimal for controlling the fan of cooling tower. Since the wet-bulb temperature would become higher than the set temperature when the air temperature is particularly high, water temperature will not reach the set temperature.

Therefore, the fan keeps rotating at high speed, failing in energy-saving operation. FRENIC-HVAC automatically estimates the wet-bulb temperature and controls the fan so that the cooling water is interlocked with the air temperature in order not to use unnecessary electric power

 

Energy Saving for the environment and our children's future
The first slim-type inverter specialized in energy-saving from Fuji Electric. Achieves a great effect on power-saving of pumps and blowers!
Contributes drastically to cost reduction by cutting power consumption!

The water business market including water purification plants and wastewater plants has continued to grow in recent years. Using a large volume of water, cost reduction is required and it largely depends on how efficiently water can be managed. It is of course achieved by reducing the amount of water to be used, however, the reduction in power consumption in water transfer and supply also allows significant cost reduction. And the key to that is the dedicated inverter which controls pumps and motors. The FRENIC-AQUA series, a Fuji’s new product, helps energy-saving of pumps, eliminating ineffectual operations by adjusting the amount of water properly to produce a significant effect both on electricity conservation and on cost reduction.
