The DES system is an energy-saving ready-made set of pump groups dedicated to operating two heating circuits.
Our sets are equipped with high-performance DEFRO ECOFLOW ENERGY PLUS circulation pumps with a wide range of adjustments. The standard equipment of each of the 3 versions is an air vent, a drain valve, as well as ball valves with thermometers with the function of a non-return valve on the return and a well for the temperature sensor on the supply side (only in mixing groups). The insulation of the clutch and pumps is made of EPP, and the return and supply pipes are made of foamed EPDM, which prevents excessive cooling of the heating medium. The hydraulic clutch is equipped with a dirt separator. Mounting console included.
