2. Operation principles
Ensave ESII Energy Saving System is a state-of-the-art energy saving product which adopts the latest and self-developed patent IC control technology. Without any alteration of motor speed, it dynamically adjusts the voltage and current to a motor as its load changes and constantly monitors the motor’s load and calculates the exact amount of power required at any time, hence, reducing the amount of electricity used. The electric efficiency can remain constant under the condition of no-load to multiple loads. If there are any faults in the system itself, it will automatically switch into bypass mode and will not affect the performance and the production of the machine.
Phasing degree of voltage and current of motor continuously monitor by Ensave Energy Saving System will change the phasing degree in 1/100 second in accordance with the alteration of load-carrying. It adjusts the voltage root mean square supplied for motors, as a result the magnetic comprehending hysteretic loss is minimised, and the copper loss is reduced, so as to ensure good matching of the output torque of motors and the loading demands.
Ensave ESII Energy Saving System automatically tracks and runs from 11KW to 500KW in 3-phase motors.

ESHydro - ECP600S Constant Pressure System
The ECP600S Constant Pressure System is the perfect pump to supply constant pressure for house, high rise building, industry or commercial application. It comes along with a pressure tank, pressure gauge and pressure transducer. The pump will speed up or slow down automatically in response to an increase or decrease in water demand, and it will really maintain a true constant pressure so there will be no more annoying pressure fluctuations when the second shower was turned on.
OPERATION
When the system is installed and commissioned, the required operating pressure will be set. The pressure is continually monitored during operation via the pressure transducer located on the discharge manifold. As the flow demand increases (more outlets turned on), the pressure transducer senses a slight drop in pressure and increases the speed of the pump (water flow rate increases) so that it maintains the pressure at the higher flow rate. So, the system checks the actual operation data against the allowable operation range and sets necessary actions to avoid operation below a certain flow rate. This is done by reducing the speed or shutting down if operation within the allowable range cannot be reached.
After an interruption to the water supply, this system will start automatically. A rotating motor will be caught by the E600 controller and the torque will be established smoothly. And it results in a higher reliability and a longer maintenance interval for the motor.
BENEFITS
Ensave ECP600S offers several benefits, some of which are relatively easy to quantify, and others which are less tangible.
Efficient Energy Saving. It can superimpose the pressure of water distribution system with a saving of at least 20% than that of traditional quadratic pressurizes water supply equipment.
Improved Process Control. By matching pump output flow or pressure directly to the process requirements several variations can be corrected more rapidly, which improves process performance. There are fewer livelihoods of flow or pressure surges when the control device provides rate of change, which are virtually infinitely variable.
Improved System Reliability. The reduction in speed of the pump has major benefits in reducing pump wear particularly in bearings and seals.
COVERAGE
ECP600S constant pressure multistage pump can be used in many areas and places like: Residential area, Housing estate, Industrial lot, Commercial lot, High rise building, Water plant, Spa, Jacuzzi, School and all those places that need a constant pressure.
ESHydro - ECW Chilled Water Storage System
Cooling is a main concern of commercial building owners. Many building are populated with people, heat-emitting office and production equipment, and ample lighting – all generating so much heat that cooling is required during most of the working hours all year. Most of these hours occur during the peak hours defined by the electric rate structure. Cool storage can shift all or most of this use to lower-cost off-peak hours resulting in lower operating cost without sacrificing occupant comfort, and can contribute to improved utility load factors. Typically, this is done by storing chilling water in a tank during the night, and drawing from it during the day to provide space cooling.
Most power generating facilities reach their peak capacity during the middle of the day. In order to meet the demand of their customers, they must size their production facilities for this peak production. To compensate for the cost of over-sizing their equipment, they often bill demand charges for the largest users.
Thermally stratified chilled water storage systems reliably maintain thermal separation by taking advantage of gravity to maintain the heavier chilled water separate from the lighter return water. So, the water will stratify into horizontal layers according to temperature, forming a natural barrier between warm and cold water in the tank (Refer to picture above). This region is called the thermocline, and acts like a physical boundary between supply and return water. The thermocline is shifted upward as the tank is charged, and downward as the tank is discharged.
From the utility perspective, the use of cool storage by commercial customers makes more efficient use of existing generating capacity and can reduce the need for new capacity.
The advantages to the customer can include first cost benefits, a lowered bill and increased operational flexibility. The use of cool storage decreases electric costs by reducing the building’s peak electricity demand. As in most countries there is a substantial rate different between day time (on-peak) and night time (off-peak).
Chilled water storage can offer significant reductions in chiller energy consumption because it allows the chiller to operate at efficient capacity levels and, generally, at reduced condenser temperatures.
This type of system is suitably for use in Airport, Hotel, Shopping mall, Hospital, Service apartment, and those places which has a high demand for air conditioning.
