Circulation Swimming Pool Heat Pumps  2HP – 25HP 50HZ / 60HZ If you want an energy-efficient way to heat your swimming pool and enjoy swimming for as much of the year as possible,Website: , then a heat pump pool heater is the best way to do it. LANOD series energy-efficient heat pump pool heaters are the ideal choice for in-ground pools and spas. With all-metal cabinet construction and industry-leading component parts, LANDO heat pumps have no equal in the industry. Step up to a new degree of comfort with a LANDO heat pump, and be assured your backyard investment will be there when you need it, year after year. The LANDO swimming pool heat pumps are the perfect solution for above-ground and smaller in-ground pools. Smaller footprint, robust construction, and full featured design elements. Easy-to-use digital controller and simple water line hook ups make operation and installation.  LANDO Swimming Pool Heat Pumps ®, which heat and cool the pool. This units extend the swimming season longer than any other heat pump by continuing to operate in low temperatures. Heat Pumps Features : ●High efficiency by using R410a refrigent gas●COP (Coefficient of Performance) of up to 6.5●Operate down to -15C degrees●Can Heat and Cool the water●Suitable for swimming pools, SPA ,Hotel swimming pools etc .●Hot gas defrost cycle to allow operation at lower temperatures●Titanium heat exchanger - The use of titanium for the heat exchanger leads to efficient heat transfer without any dangers of corrosion.●Digital control panel on all models●Green UK & European compliant extra efficient refrigerant gas (R410a)●Refrigerant gas pressure gauge●Delivery in 1-week from order●1-Year parts and labour warranty●Designed & Built For Long Life & ReliabilityUsing high quality materials in the build of the  Heat Pump and a titanium heat exchanger means it is practically "Bullet-Proof" to erosion from Chlorine, Bromine or Salt in the water. Also, the titanium heat exchanger is oversized to improve efficiency and make the LANDO Heat Pump even more cost effective and great value for money.General : Easy Installation The LANDO Swimming Pool Heat Pump is designed intelligently and exceptionally compact for ease of installation. One of the simple but handy design additions on the LANDO Heat Pump is the integrated flow switch which will sense the water flow and automatically start the heater when the pool pump starts and stop it when the pump shuts off. Simple, but very handy.State Of The Art ControlThe integrated microprocessor in the LANDO Swimming Pool Heat Pump monitors all the sensors and controls the device without any intervention needed by the user. Electronic display and control with easy operation is standard on all  LANDO Swimming Pool Heat Pumps.Quiet RunningThe  LANDO Heat Pumps use of a highly efficient, low sound compressor, a low noise fan and an oversized heat exchanger on every unit, makes the   LANDO Heat Pump extremely quiet in operation.SELECTING A HEAT PUMP POOL HEATERHeat pump pool heaters cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters. Therefore, you'll save more money in the long run.  When selecting a heat pump pool heater, you should consider its:●Size●Efficiency●Costs.DETERMINING HEAT PUMP SWIMMING POOL HEATER EFFICIENCYThe energy efficiency of heat pump swimming pool heaters is measured by coefficient of performance (COP). The higher the COP number, the more efficient. However, there is no standard test for measuring the COP. Therefore, you really can't compare the COPs of different models unless you know that the manufacturers used the same test for each model. For example, the same heat pump will operate at a higher COP when the outside air temperature is higher.  Typically, manufacturers measure the COP by testing a heat pump pool heater with an outdoor temperature of 80ºF and pool temperature of 80ºF. COPs usually range from 3.0 to 7.0, which converts to an efficiency of 300%–700%. This means that for every unit of electricity it takes to runs the compressor, you get 3–7 units of heat out of the heat pump50HZ Swimming Pool Heat Pumps Specification :  　LD-02STiLD-03STiLD-04STiLD-05STiLD-10STiLD-13STiLD-20STiLD-25STiAir /Water 24℃/26℃Output Power (KW)8.9415.1118.0021.0040.0052.0090.00105.00Input Power(KW)1.522.663.213.827.509.8017.0020.00COP5.885.665.605.505.305.305.305.30Current7.2712.7315.366.8113.3717.4730.3035.65Air /Water  15℃  /26℃Output Power (KW)8.1312.8915.9518.6531.0040.0081.0095.00Input Power(KW)1.322.583.133.736.208.1016.9019.80COP5.345.005.095.005.005.004.804.80Current6.3212.3414.986.6511.0514.4430.1235.29Air /Water 7℃ /26℃Output Power (KW)5.6810.4513.1716.0026.0033.0070.0081.00Input Power(KW)1.522.673.103.726.007.8016.3018.80COP3.903.924.254.304.304.304.304.30Current7.2712.7814.836.6310.7013.9029.0633.51Electric Power　220V/50Hz380V/50HzCompressorPanasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    RotaryScrollScrollScrollScrollScrollScrollScrollHeat ExchangerTitanium Tube in PVC ShellTitanium Tube in PVC ShellRefrigerantR22/  R417A /R410AR22/  R417A /R410ADefrostIncludedIncludedRemote5meter Signal Wire5meter Signal WireCabinetGalvanized steel sheet and sprayed baking paintGalvanized steel sheet and sprayed baking paintWater Connection Port(mm)Exterior 50mm/ Interior 40mmExterior 60mm/ Interior 50mmExterior 70mm/ Interior 60mmFan Power Input (w)90200400400400400*2850850Fan Power Output(w)5090250250250250*2550550Fan  (RPM)750850850850850850940940Noice  dB(A)5149495858586565Water Flow Rate(m3/h)6~88~1010~1212~1520~2525-3040-5050~60Water Pressure Drop (Kpa)1414141516183035Product Dimension(mm)570*500*600710*710*850810*810*1050810*810*10501580×910×11801580×910×13802000*1100*23002000*1100*2300Packing Dimension(mm)630*575*770840*840*1030950*950*1250950*950*12501650×980×13401650×980×15402200*1300*25002200*1300*2500Net/ Gross Weight(kgs)51/57100/115112/122147/170250/280280/310620/540650/57060HZ  Swimming Pool Heat Pumps Specification :　LD-03STiLD-04STiLD-05STiLD-10STiLD-05STiLD-10STiLD-13STiLD-20STiLD-25STiAir /Water 24℃/26℃Output Power (KW)16.0019.0024.0048.0023.5045.0056.0095.00110.00Input Power(KW)2.913.254.369.064.278.4910.5717.9220.75COP5.505.605.505.305.505.305.305.305.30Current15.2018.3016.0032.007.1914.2918.5032.0037.00Air /Water 15℃ /26℃Output Power (KW)13.0017.2019.7039.4018.6533.0042.0083.0097.00Input Power(KW)2.603.373.947.883.306.608.4017.2920.21COP5.005.105.005.005.005.005.004.804.80Current14.5016.1414.0528.095.5613.2016.5032.0038.00Air /Water   7℃ /26℃Output Power (KW)10.4513.1716.8026.0014.0028.0035.0072.0085.00Input Power(KW)2.463.103.916.053.266.518.1416.7419.00COP4.254.254.304.304.304.304.304.304.30Current13.5015.0013.5026.806.4012.8015.0030.5039.50Electric Power　220V/60Hz/1PH220V/60Hz/3PH380V/60Hz/3PHCompressorPanasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    Panasonic    ScrollScrollScrollScrollScrollScrollScrollScrollScrollHeat ExchangerTitanium Tube in PVC ShellTitanium Tube in PVC ShellTitanium Tube in PVC ShellRefrigerantR22/  R417A /R410AR22/  R417A /R410AR22/  R417A /R410ADefrostIncludedIncludedIncludedRemote5meter Signal Wire5meter Signal Wire5meter Signal WireCabinetGalvanized steel sheet coatedGalvanized steel sheet coatedGalvanized steel sheet coatedWater Connection Port(mm)Exterior 50mm/ Interior 40mmExterior 60mm/ Interior 50mmExterior 70mm/ Interior 60mmFan Power Input (w)200400400400400400400*2850850Fan Power Output(w)90250250250250250250*2550550Fan  (RPM)850850850850850850850940940Noice    dB(A)494958585858586565Water Flow Rate(m3/h)8~1010~1212~1520~2512~1520~2525-3040-5050~60Water Pressure Drop (Kpa)141415161516183035Product Dimension(mm)710*710*850810*810*1050810*810*10501580×910×1180810*810*10501580×910×11801580×910×13802000*1100*23002000*1100*2300Packing Dimension(mm)840*840*1030950*950*1250950*950*12501650×980×1340950*950*12501650×980×13401650×980×15402200*1300*25002200*1300*2500Net/ Gross Weight(kgs)100/115112/122147/170250/280147/170250/280280/310620/540650/570
