Series BM Avant Garde Print Email

dunhambush avant-gardemini-bookAvant-Garde award winning fan convectors are the next generation heat emitter. Careful and ingenious design of Dunham-Bush's Avant-garde allows condensing boiler plants to operate at maximum efficiency at all times and with the minimum of capital investment.

The extensive Dunham-Bush range of Series AM and Series BM units are all available in the Avant-garde variant. The only difference is the position of the flow and return connections due to integration of the motorized valve.

Traditional low-pressure hot water (LPHW) heating systems operate at 82 °C flow and 71 °C return during peak loads on both compensated (radiators etc) and constant temperature systems (fan convectors etc). The Dunham-Bush Avant-garde unit is designed to operates at 55 °C flow and 35 °C return during peak loads, whilst maintaining the same duty, options and features as the Dunham–Bush range of Series AM and Series BM fan convector heaters.

  • Boiler return temperature is always below 55 °C ensuring the boiler is in condensing mode at all times.
  • Increased differential water temperatures across the coil, reduces pumping energy by up to 87%.
  • Decreased flow and return temperatures reduce standing losses from pipe work.
  • Low water content and thermal mass of unit allows rapid response preventing a protracted warm-up period and temperature overshoot.
  • Integral 4-port valve prevents wasteful natural convection during mild conditions (2-port valve option available upon request).
  • Optional brushless DC motor reduces electrical power consumption by up to 80% compared to standard motors.
