resistive load banks manufacturer supplier

      
     Load banks have an important role in the maintenance of stand by power generation equipment.
     Load Banks are a cost effective way of keeping things running.The necessity and dependence on power at mining sites, oil and gas refining, in hospitals, transport and many other essential services has meant a rapid growth of back up generators and UPS systems for back up power.The increase of computers and telecommunications equipment demands faultless performance in the event of power down conditions. This can only be fully achieved by resistive load testing the stand by systems on installation and at regular intervals.The life and efficiency of diesel generators can be greatly reduced when running under-loaded, causing damage to the engine, fouling of valves and exhaust ports. Also causing extensive cylinder bore glazing to a point where engines could stall or completely fail to start when they are needed the most - during a mains power failure.Only resistive load banks can guarantee the ultimate operating conditions and efficiencies of stand by generators.
     The importance and necessity to test batteries and UPS systems can only be achieved with resistive load banks. Batteries quite often require a full discharge test to monitor cell condition.Auxiliary equipment such as resistive load banks ensure regular and reliable load testing can be performed without interruption to mains power supply and leaving you confident that your emergency power system will function during any mains power failure.

Residential all in one energy-saving heat pump water heater

Residential all in one energy-saving Heat Pump(The article from www.heatpumpcn.com)
   The small footprint of the Compact Heat Pump lets you install it as close as six inches away from your home, or place it on a roof. In the outdoor unit the refrigerant meets the outdoor air in the evaporator (heat exchanger). The air is drawn through the evaporator by a fan located on side of the Air Source Heat Pump.
     The refrigerant, which is in a liquid state absorbs free energy from the air and evaporates in this process. A sensor in the expansion valve ensures that the liquid refrigerant collects the correct amount of the 'free energy' before the refrigerant (now in a gas state) is led into the compressor. The compressor increases the pressure of the refrigerant. The temperature of the vapour reaches approximately 100°C. The warm gas is then led into the condenser. The condenser is the heat pump's heat emitting part. In the condenser, which is a fully brazed heat exchanger in stainless steel, the refrigerant (gas state) meets the water from the heating system (radiators and/or floor coils). When the warm gas is cooled by the circulating heating water, it condenses into a liquid state.
    Residential Compact air source  Heat Pump.Energy is emitted in this process to the heating system or the hot water. After the condenser, the refrigerant, which is now in liquid form, continues through a drying filter. The drying filter is used to collect any moisture in the system. After the filter it continues on to an expansion valve. The refrigerant pressure is lowered in the expansion valve. This also causes the temperature to drop. When the refrigerant has left the valve and passes the evaporator it changes to vapour again. This completes the refrigerant circuit. The expansion valve is equipped with a sensor (bulb) just before the compressor. The sensor controls the amount of fluid entering the evaporator.

    To understand the concept of heat pumps, imagine a refrigerator working in reverse. While a refrigerator removes heat from a box and expels it into the surrounding air, a heat pump water heater takes the heat from the air and transfers it to water in an enclosed tank. They are called “hybrids” because in addition to a heat pump they also have traditional electric resistance heating elements for times when demand exceeds what the heat pump can produce.
Installation Considerations
   Because of their noise and cooling effect, heat pump water heaters are better suited to basements than living spaces, especially if there is extra heat available from a boiler.
   Remember that you’ll need a place to drain the condensate. This can be pumped outside or passively drained to a sink or floor drain lower than the heat pump condensate port.
    For optimum efficiency, install a heat pump water heater where the temperature stays above 45°F and provide at least 1,000 cubic feet of air space around the unit. This would be a typical 10’ x 15’ room.
     Be sure to give the unit the recommended clearances from walls to ensure adequate circulation.  Be sure the ceiling is high enough to accommodate the unit.
    Insulate the first six feet on incoming and outgoing pipe to minimize heat loss through distribution.
