New for H&V07, Fläkt Woods is launching an upgraded Econet® energy recovery system, with changes that have made it 70 - 75% efficient (50% more efficient than plate heat exchangers) and more versatile than any HVAC system currently available.
The difference between a system with 50% and 75% efficient energy recovery device is a reduction in life cycle costing by 40%. This is why it is essential to have a high efficiency energy recovery system like Econet.
Econet integrates energy recovery, heating and cooling into one set of coils, so components, such as heating/cooling coils, pumps, valves, piping and insulation, are no longer required. This brings significant cost savings as well as a reduced footprint. Advanced Econet also optimizes the energy recovery using a new pre programmed control system, which constantly ensures the minimum amount of energy is used to meet the air requirements.
Energy Efficiency Improvements
Space savings and improved functionality has been achieved by synchronising all the controls in one unit, a new controller constantly calculates energy recovery and heating and cooling powers. The improved Econet features more flexible communication capabilities, and with remote functionality.
Additionally, Econet can now be supplied with a double pump function; two pumps and two frequency inverters. If one of the pumps fails the other one takes over; essential for projects/applications where continuous functionality is necessary; for example in process and pharmaceutical industries as well as hospitals.
Due to the unique layout of Econet the configuration of the supply air unit is simplified, so only one supply air coil is needed instead of three. This means reduced lengths and often reduced pressure drops in the unit. This can offer not only savings, but smaller plant rooms leading to more lettable floor space in office developments.
Econet is supplied with a prefabricate pump unit. All necessary components for optimising the energy recovery as pump, frequency inverter, controls and necessary valves and sensors are included. This reduces installation time, saving both time and money.
