Constant Humidity Controller
(modulating grain drying gas burner)
Since the development of the first Harvest Constant Humidity Controller (CHC Gas Burner) in 1979, Harvest Installations has been supplying UK and International farmers with guaranteed drying conditions, 24hrs a day, every day.
​
The Constant Humidity Controller (CHC Gas Burner) system has a proven record of accuracy, efficiency and economy with thousands of units in use on all combinable crops and onions across thousands of stores nationwide.
With a range of sizes from 200,000 to 4,000,000 BTU/hr all using the same plate type burner head, independent burner fan and up to date electronics and controls, they have proved themselves for over 30 years.
​
Design
The fan performance is critical to it's efficiency, low power consumption and low running noise of Harvest CHC Gas Burner units.
With each gas burner head of each model being designed and manufactured to give maximum output in a compact design, this combined with highly efficient use of available fuel.
Accuracy is everthing
The CHC gas burner control electronics are mounted in
our purpose built housing, incorporating a large
display and simple controls for easy setting of the CHC gas burner unit.
​
The CHC gas burner control system modulates 7 stages of heat output to control the stores relative humidity or temperature. Levels of accuracy and performance as verified by independent testing bodies ensured efficient controlled drying without the fear of over drying.
