Currently, gas boiler brands on the market a wide range of different quality. For our customers, in order to find a suitable own business, for heating hot water boilers, industrial or domestic hot water, to master some basic boiler purchase criteria.
Water level gauges and pressure gauges in gas-fired boilers require that the lighting voltage should not exceed 36V, because they are located in a relatively high position and temperature, so it is possible to have problems such as aging in the course of use of their leads. At this time, Safety considerations are the use of safety voltage, therefore, there will be such a specific requirement.
Clearly, high calorific value gas in a low calorific value greater than the value, the difference is part of latent heat of vaporization of water vapor. The actual industrial and civil engineering applications commonly used in gas low calorific value gas is calculated. If the calculated low calorific value, condensing gas boiler is capable of absorbing latent heat of vaporization, i.e., the thermal efficiency may reach a high of 108%.
R & D center built and put into use, is a landmark event in the party group was founded two decades of fast, fast Group is party to enhance the quality of another milestone, is quick to understand the user side of the new window, it is to demonstrate a new gas boiler technology platform. Fang fast development center connotation of high-tech feel, quite the image of modern atmosphere, welcome your visit and visit!Free Chat
