Transformer station for concrete heating SPB-20 The station is "the youngest" in its family both in terms of its weight and dimensions, as well as in terms of energy consumption and power. The use of this station will not only significantly reduce the construction time of small reinforced concrete structures on an individual site, but will also help to provide temperature conditions for the correct hardening of cement in all types of small construction at ambient temperatures from +10 to -40C. If you need to buy a concrete heating station that can be easily moved by one person within a small construction site and provide electric heating of hardened concrete with a relatively low power consumption due to its low power, then this device will meet all the listed requirements. The SPB-20 heating transformer station provides heat treatment of concrete by supplying voltage to the special PNSV electric wires pre-installed in the formwork. The productivity of the concrete heating method with the embedded heating wire depends on the ambient temperature, the presence or absence of additional heat-insulating surfaces, the amount of reinforcement, and ranges from 0.4 to 1.0 m3 of concrete per 1 kW of the station's load power.
