Hydronic HAH-250

Hydronic heaters are ideal for providing dry, hot air in tightly enclosed or highly insulated structures under construction that require flameless operations. Hydronic heating systems use a boiler or heat exchanger to heat a glycol solution which is then pumped through flex hose connected to a portable heat exchanger or fan coil. A blower fan then moves air across the heated coil and into the space. Next, the heat exchangers heat, circulate, and reheat interior air within the structure resulting in minimal ventilation of the space. Multiple heat exchangers can be placed throughout the facility allowing the heating of separate areas. HAH-series heaters can also help thaw frozen ground or cure slabs and footings by recirculating the glycol solution through a heat transfer hose that is laid out in a serpentine pattern.

  • Flameless operation
  • No combustion byproducts
  • Multiple heat exchangers can be placed to heat separate areas
