Welcome to Sunpower Group ! 中文
Most steam pipe network systems in our country has been running in the state of high energy consumption and low efficiency for many years. The serious waste is specified in running, popping, dripping, draining, temperature and pressure drop is too large, which affects normal industrial production.

Sunpower creates a systematic, long-term, and thermal insulation energy saving project for steam pipe network from network design, process improvement, pipeline nanometer materials, heat pre-insulated pipe support application, insulation structure optimization to thermal clamp design of special parts(valves, flanges and fittings), which ensures safe and reliable operation of enterprises in the network life cycle as well as the maximum return.


The first study of this technology (in the year of 1996): Pipe network design, heat pre-insulated pipe support, thermal insulation structure optimization, thermal insulation material selection, etc.

The low cost of optimal effect: The best material and the best structure;

The best heating effect: Large range, less heat loss and little pressure drop;

This combination is to ensure the pipe network safety and the insulation is in best performance. Increasing the heating radius to ensure steam quality.

SunPower uses composite nanometer insulation layer of high-tech, keeps heat preservation for pipe. Compared with the traditional thermal insulation, energy-saving is more than 30% as well as reduces the insulation thickness greatly, which is 30% thinner than traditional type of insulation thickness. Heat dissipation area is reduced, on the one hand reduces the overall heat loss, which saves a lot of energy; On the other hand, saves construction space, which reduces investment cost.

Ø SANanometer Hot Insulation Material

Nanometer material is absorbent, the thermal conductivity at room temperature is less than or equal to 0.018w/m.k, and has excellent insulation performance with no deformation in low temperature condition.

Nanometer material is not deformed or burning after high temperature test, and can still maintain good compression and thermal insulation properties

Heat insulation performance is excellent that you can touch the unexposed surface.

According to statistics, the annual heat loss of a DN100-150's bare valve is equivalent to calorific value of burning 1 ton of coal. Heat preservation and energy efficiency of the valve directly affects energy consumption and economic efficiency of the equipment. Our company uses the new heat preservation technology, which can be used repeatedly with good effect, convenient installation and maintenance.
