GRO Brooder Heaters

GRO Brooder Heaters

GRO Series Brooder heaters are designed to provide infrared heat in swine and poultry houses the same way the sun heats our earth. Heat from the brooder burner radiates warmth directly toward the litter, flooring and animals below it without heating the air first, resulting in reduced fuel consumption and increased animal comfort. The GRO40 and GRO40HP series heaters are designed for poultry house heating and the GRO17000 brooder provides exceptional performance in both poultry and swine applications.


  • Brooders provide multiple heat output locations in barns, providing redundancy and continued warmth if a unit fails to light or otherwise stops operating.
  • Radiant heat works like the sun, warming the animals and litter below it without warming the air first.Radiant heat works like the sun, warming the animals and litter below it without warming the air first.

  • Brooder heaters produce a zone of heat that ranges in intensity, allowing animals to move to an area they feel most comfortable.
  • The radiant heat from brooders help dry out the poultry litter below them which helps reduce ammonia levels and produces a thermal reservoir that stores heat and maintains a warmer litter area.
  • All GRO Series brooder heaters are CSA Certified for safe and efficient operation.

GRO40 Brooder

The GRO40 series brooder is a 40,000 BTU/Hr unit designed to provide increased resistance to corrosion from humidity, ammonia, dust and moisture. Improved design features mean lower maintenance requirements, greater reliability and improved durability flock after flock in the operating conditions of today’s modern poultry facilities.

The GRO40 brooder series are constructed of corrosion resistant materials to help extend service life in modern poultry house environments. DSI (Direct Spark Ignition) dual fuel LP/NG model (shown) includes a moisture resistant enclosure to protect the control module.The GRO40 brooder series are constructed of corrosion resistant materials to help extend service life in modern poultry house environments.

Corrosion Resistance

  • The stainless steel burner chamber, emitter assembly, mounting brackets and gas lines provide increased corrosion resistance and longer life compared to other materials
  • The DSI model brooder features a black plastic moisture-resistant enclosure that houses the ignition control module to protect it during grow-out and wash down
  • The aluminum deep dish canopy is corrosion resistant and reflects heat toward the litter where it is needed most

Design Benefits

  • The Direct Spark Ignition (DSI) model brooder features a dual fuel gas regulator, allowing the heater to operate using either propane or natural gas with a simple adjustment. This new feature eliminates costly retrofit expenses involved with switching gas valves and orifices if production requirements change
  • A safety pan below the burner helps shield the litter area directly beneath the brooder
  • Pilot light models uses the patented Windbuster™ Pilot System and have an easily removable shield that permits quick access to the pilot orifice for lighting and cleaning
  • The stainless steel burner assembly is easily disassembled for cleaning, and the main burner orifice is easily removed by sliding a quick release bracket, reducing maintenance time and increasing operating life

Heating Efficiency

    The 60° emitter angle of the GRO40 brooder effectively directs heat toward the litter and birds underneath it. The 60° emitter angle of the GRO40 brooder effectively directs heat toward the litter and birds underneath it.

  • The GRO40 brooder features a unique 60° emitter angle that combined with the deep dish aluminum canopy puts more radiant heat into the primary brood area, resulting in fuel savings and fewer total brooder units to meet heating requirements.
  • Radiant heat warms the birds and litter directly below it without having to heat the barn air first, resulting in fuel savings and the ability for birds to move to a zone of heat under the brooder that is most comfortable to them
  • The stainless steel emitter assembly is fully insulated and enclosed to prevent the insulation from crumbling or otherwise becoming distorted during the heater’s lifetime
  • The fully enclosed insulation in the emitter increases durability and also prevents heat loss back through the emitter that would otherwise happen if insulation wasn’t kept in place
