Dehli heat exchange equipment (Beijing) Co., Ltd. is a supplier of detachable plate heat exchanger, plate wall heat exchanger, flue gas waste heat recovery device, heat exchange unit, all welded plate heat exchanger and other heat exchange equipment. It is committed to the research, development, sales, service and consultation of various heat exchangers. 

      Based on more than ten years of experience in the field of plate heat exchanger and service, the R & D team of the company has designed and developed plate heat exchanger products with higher pressure bearing capacity, more accurate positioning and easier installation and maintenance, and has obtained patents. In the key components: the structure design of heat transfer plate and sealing gasket is in the leading position in the same industry in China. The heat transfer plate with its special corrugated structure design makes the heat transfer characteristics, pressure drop characteristics and pressure bearing characteristics more optimized. The sealing gasket with special structure of non stick button type makes the sealing more reliable and easier to operate. At the same time, in today's increasingly important environmental protection and energy saving, the company has also developed a heat exchange device for flue gas waste heat recovery, which can achieve low-level heat recovery and utilization, improve energy utilization, reduce costs, provide guarantee for process optimization, and realize energy conservation and emission reduction.

       The company has self-developed button type series plate heat exchanger products, at the same time has a variety of small temperature difference conditions special version, ripple depth of 2.0-3.4mm, used for low-grade heat and cold source recycling, such as ice storage, heat pump system. Different types of products can be divided into different industrial fields, such as HVAC, electric power, petrochemical, food and pharmaceutical, shipbuilding, iron and steel metallurgy, machinery manufacturing, new energy and fishery breeding.

      The self-developed plate wall heat exchanger of the company can be widely used in the field of heat recovery, such as sewage heat recovery, waste water heat recovery, etc., with high heat exchange efficiency and flexible layout, which can be customized according to the space of the user's site.

      Welding plate type flue gas waste heat recovery device: in view of the situation that the exhaust heat of coal-fired or gas-fired boiler is wasted and the fuel cost remains high, our company specially develops plate type waste heat recovery device for boiler flue gas waste heat recovery, which can be used to preheat the air entering the furnace of coal-fired boiler, or preheat the boiler water supply, with high heat exchange efficiency and small land occupation, And it can effectively reduce the problem of ash deposition and ash removal, shorten the payback period of equipment input, save fuel for users, and achieve remarkable benefits, energy saving and environmental protection
