中国买家求购wall hung combi boiler 中国买家求购wall hung combi boiler buy 110V hot water pump for wall hung combi boiler Date Posted: 31 Jul 2009 Offer Expires: 26 Aug 2010 Detailed Buying Lead Description Ailunsi central heating gas boiler heaters with ten protection function. Rated heat load(KW), 30. Heat effciency(%), 92%. Rated hot water production (L/min) t 25k, 15. Rated heat output(KW), 27.2. Water pressure (MPa), 0.6. Working voltage, AC220-50Hz, Rated power(W), 110. Heating area reference(m2), 230 or lower. Scope of heating water temperture, 30 Centigrade to 80 Centigrade. Scope of shower water temperature, 30 Centigrade to 60 Centigrade. Volume of expansion water tank(L), 8L. Opening pressure of heating safety valve(MPa), 0.3Mpa. Pump life(M), 5M. Smoke exhaust, Compulsory gas supply and exhaustion. Size of pipe joint, G3/4 for heating pipe and gas pipe. G1/2 for heating water. Net weight, 35kg. Gross weight, 37kg. Packing dimension: 820*450*365mm. 2.The electronic components and major patrs are made by top level suppliers from Germany, U.S.A. and ltaly. 3.Control circuit board: The control core on the operation of highly intelligent devices and safety protection is the pride of Ailunsi, having many indep- endent intellectual property. 4.Many types of built- in energy-saving protection programs: Quick starting on sanitation hot water system; Short time circulation control; time delay control on circulating pump. 5.Compatible with all general characteristics of Euro type boilers; The digital display screen realizes man-machine conversation and shows 4 working modes: Normal mode, State mode, Diagnosis mode and Failure mode. 6.Closed combustion chamber: The blower drains out the exhaust gas and absorbs the fresh air from outside. The combustion cha-mber and room of house are separated completely, safety guaranteed. 7.Fuel gas ratio regulation: Adopting Sit827 or CPV-H2230BT gas valve and ignition control; realizing proportional control. The tem-perature of the heating system and the sanitation hot water outlet is very stable, creating a comfortable living environment. 8.Water pressure protection: When the heating system pressure is higher than 3 bar, the pressure will be relieved by the relief valve. When the water pressure is lower than 0.5bar, the heating boiler may display failure code. 9.Operation in low water pressure: The start-up flow of living hot water is 3.5L/min. Even in the region or floors with very low water pressure, the hot water flow is still stable. 10.Fault indication: When the machine is out of order, the display screen shows failure code. 11.Two stages intelligent anti-freezing system: If the temperature is lower than 8, the circulating pump of the wall hung boiler starts automatically. 12.If the temperature is lower than 5 in continuous mode, the wall hung boiler starts automaticaily to prevent freezing of boiler and heating system. 13.Air pressure protection: When the fume duct is blocked or the down draft occurs, the flame is extinguished automaticaliy. When the blockage is removed or the air direction and air force are normal, the machine works automatically. 14.Power off and gas off protection: The machine stops working automatically when the power is off or the gas is off. When the powers on, the machine works automatically in its normal operating conditions. The machine can not work automatically after the gas supply comes back. The machine can be started manually only to normal operating mode. 15.Water pump anti seizing device: When wall hanging boiler stops the service for 24 houst, the water pump works for extra 2 minutes to prevent seizing of water pump. 16.Extra exhausting function of the exhaust air system: When wall hung boiler stops the service, the blower works for extra 20 seconds before stoppi- ng to drain off the residue exhaust gas inside the wall hanging boiler. 17.The efficiency is as high as 92%. 18.It adopts Swedish SWEP plate heat exchange with living hot water efficiency up to 92%. todaymx，如果您要查看本帖隐藏内容请回复 |
