The system basically consists of the combination of:

The DUALTOP system is designed for the heating of any industrial and commercial environment.

DUALTOP is available with heat outputs of 32 kW, 47 kW, 65 kW, 94 kW, 107 kW, and offers a high average seasonal efficiency.

The wall-mounted condensing boiler has an IPX5D degree of protection and the fan heater IP54.

The supporting structure with an ABS and painted steel shell for the fan heater, and ABS and painted INOX steel for the external boiler, both guarantee robustness and solidity.

The condensing boiler is equipped with a class 5 and 6 premixed low NOx burner. An electronic control unit manages automatic modulation of the thermal load and variable speed ventilation with high air flow rates.

The DUALTOP split system consists of a wall-hung “CLIMAIR COND” high-efficiency condensing boiler for outdoor use, combined with one or more “LEADER” fan heaters to be installed in the room to be heated. In the “C” version, the system is designed to be combined with a cooling unit for summer cooling.

The package includes:
  • CLIMAIR COND wall-mounted condensing boiler
  • On-site flue gas exhaust kit
  • LEADER indoor fan heater(s)
  • External probe for climatic compensation
  • Dual-speed room thermostat kit

Various configurations possible with 5 types of boilers and 5 types of fan heaters
The DUALTOP split system heats quickly thanks to a low thermal inertia of the condensation boiler exchanger
