Direct Heaters

 

Thanks to its reliable and high quality components, direct fired heaters work for more than 40 years with minimum maintenance need. High resistant stainless steel case, different fan options for agriculture and horticulture applications, ignition control, overheating control, different operation modes and easy maintenance are only a few features which make them best in class. With various heat and fan capacities, you can select the most suitable heater for your farm or greenhouse.

Direct air heating advantages:
  • Heat output contains hot air and CO2
  • 100% efficiency, fast heat-up time
  • Low installation costs
  • Very reliable and proven system
  • Easy to commission
  • Easy to maintain
  • Resistant to water jet cleaning

GP14
Overview

Ermaf hot-air blowers are manufactured from high-grade stainless steel which makes them impervious to unfriendly environments. The automatic ignition is triggered by an ignition electrode. The heating operation is monitored by an ionization safety. The appliance is fitted with an overheating safety. A fully automatic operation is obtained through a thermostat or climate computer. The GP14 features a BCU which supports many functions such as; automatic restart after gas pressure drop or electricity drop, adjustable start delay, detailed error description visibility on control unit, flame current (ionization) read-out, extra electric connection possibilities (fans, external alarm etc.) and many similar others functions on top of these. Axial fan provides extreme durability for agriculture applications whereas centrifugal fan which is used in horticulture applications gives higher efficiency and lower noise.
