AKVASAN Repair Accumulator Tank Developed for constrained spaces and narrow openings, this model’s diameter is only 810 mm. The AKVASAN 0.5 series is particularly compact; the advantages of the efficient cylinder format have been retained. The insulation is the same as in the standard accumulator tanks, but its thickness is 50 mm due to the smaller surface area. The EK models are equipped with a domestic hot water coil, as well as daytime and nighttime resistor units.   MODEL DIAMETER HEIGHT WEIGHT  RESISTOR UNITS 5235090 AKVASAN 0,5 EK 810 mm 1550 mm 130 kg 2 5235092 AKVASAN 0,5 E 810 mm 1550 mm 120 kg 1 5235091 AKVASAN 0,7 EK 810 mm 2050 mm 160 kg 2 5235093 AKVASAN 0,7 E 810 mm 2050 mm 150 kg 1 EK = insulated, one coil E = insulated
