Indirect Heaters


The Ermaf continues to drive the Air Heater technology with its indirect fired heaters into a new era. Closed combustion technology allows air heater to extract flue gasses to outside by a chimney so that humidity and temperature are controlled with minimum fresh air need. Better air-jet length is reached in addition to improved combustion safety on natural gas or propane. 
  

    Advantages of indirect air heating are:

  • Heat output contains only hot air and no CO2 or NOx
  • Combustion gasses are extracted via chimney. The result is that no additional ventilation of combustion gasses are needed which results in energy savings and better climate
  • Increased jet air length with laminar air flow
  • For combustion, fresh air is not consumed from the installation space
  • Hot air contains no moisture; the floor is then less wet: this means less diseases and higher productivity.
  • High safety combustion
  • Improved resistance to water jet cleaning

TR75
Overview

  • Heating of greenshouses
  • Heating of stables
  • Heating of workshops and tents
  • Storage frost protection
  • Indirect fired with heat exchanger

The Ermaf hot-air blowers have proved themselves internationally for more than four decades. The heaters feature an Air heater Control Unit (ACU) which makes them easy to operate. The Thermorizer can, in combination with a thermostat and the extra functions in the ACU such as alarm in case of a failure and external reset, operate fully automatic. Due to the substantial air over-measure and effective mixing of gas / air, this appliance provides properly regulated heating. Ermaf heaters operate on natural gas or propane and allow easy adjustment. A long life is ensured by the stainless steel design of the appliance. A constant temperature in the stable is guaranteed by the fully automatic working, which is combined with a temperature-regulating thermostat. TR75 is capable of regulating itself in between 60% and 100% which helps having a stable temperature in the installation space. Additionally, by the diffuser, it is possible to adjust the heated air flow in different directions which improves air distribution.
