Direct Fired
With the ideal heat exchanging method of parallel cycle, a higher energy saving rate is achieved.
Efficio has various type of COP model. The gas consumption rate can be reduced compared with the conventional model.
Also, with the inverter control for the solution pump, you can save more fuel gas consumption .
High Efficiency
COP
Note
COP is calculated in accordance with JIS standard.
Fuel Consumption Rate at Partial Load
Note
1. Cooling water inlet temperature conditions are as specified by JIS standard (32℃ at 100% load, 27.5℃ at 75% load, 23℃ at 50% load, 18.5℃ at 25% load).
2. The above graph shows plotted points of maximum COP and the actually measured value might be changed due to machinery and/or site condition.
NE series realizes right balance of initial cost and running cost
Basic model of Efficio series
NE series achieves higher COP and lighter machine weight, by adopting compact and high-performance heat exchanger, optimized design even in the smallest details, and use of high-performance refrigerant drain heat exchanger.
The solution pump inverter control is equipped as standard and it enables efficient operation across various range of load condition from low to high, which contributes to high partial load efficiency.
NE series also delivers system efficiency and lower power consumption, by expanding the lower limit flow rate of cooling water when controlling variable flow rate of cooling water.
NE series
| Heating capacity | Cooling capacity | Fuel |
|---|---|---|
| Standard | 281 to 3,517 kW (80 to 1,000 USRT) | Gas, Diesel Oil, Dual fuel |
NU series achieves even higher partial load efficiency
NU series is equipped with high-performance heat exchanger tube and COP is improved further.
NU series
| Heating capacity | Cooling capacity | Fuel |
|---|---|---|
| Standard | 281 to 3,517 kW (80 to 1,000 USRT) | Gas, Diesel Oil, Dual fuel |
NH series delivers even higher efficiency across partial load to full load.
NH series is equipped with high-performance heat exchanger tube and also exhaust gas heat exchanger which enables more efficient heat recovery. Combustion exhaust gas is discharged at 110℃ by Efficio series, while at around 200℃ by conventional model. These features realize further improvements in performance.
NH series
| Heating capacity | Cooling capacity | Fuel |
|---|---|---|
| Standard | 281 to 3,517 kW (80 to 1,000 USRT) | Gas |
Touch Panel Operation Board
A color 5.7 inch touch panel is equipped on the operation board as a standard.
Operation can be made just following the sequential program control shown on the touch panel, confirming the operation condition, trend graph, pre-alarm and abnormal occurrence according to the displays on the touch panel.
