Direct Heaters

The direct-fired air heater GP series are now upgraded with the new ACU controller, certified according to new Gas Appliance Regulation.

These boost even further the capabilities of the air heaters, creating a new range of products. The new smart design features increase the productivity and connectivity for your farms and green houses.

The air heaters now provide not only more functionalities and reliability, but they are also more installer and end-user friendly, easier to service and clean. All the operations on the controller are much easier and faster: with an extra button on controller all is so intuitive!

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 an ACU controller 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.
