Stable indirect heating for demanding environments
The GPmp series includes the GPmp 100, 130, and 160, indirect-fired heaters built to deliver consistent, high-output heating in poultry and pig houses, as well as greenhouses. These units feature thermal efficiency above 90%, providing more heat with less fuel consumption, and can be configured with either gas or oil burners.
Designed for durability and ease of use, the GPmp comes with Munters Protect-treated components, stainless steel combustion chamber, and an IP55-rated electrical box and motor, ensuring corrosion resistance and long service life even in high-humidity or ammonia-rich environments.
The GPMp advantage
High thermal efficiency
All models exceed 90% heating efficiency, converting nearly all combustion energy into usable barn or greenhouse heat. This reduces fuel consumption and supports long-term operating cost savings.
Quiet, flexible operation
The direct-drive axial fan ensures low-noise heating and stable airflow, while also doubling as an air circulator in warmer periods by using only the fan.
Compact, easy to handle
Designed for easy hanging installation, the unit features an ergonomic frame that simplifies transport and setup. An integrated 5-pole plug socket allows for quick and secure connection to room thermostats or farm controllers.
