Unit-Heater Burner for a Commercial Greenhouse
A 20000 m2 greenhouse needed even warmth across crop zones without CO spikes. Compact Riello 40 GS5 unit-heater burners with certified trains gave steady heat and cleaner combustion.
The challenge
Cold spots stressed crops and slowed growth at the greenhouse edges.
Old heaters produced CO spikes that risked plant and worker safety.
Many分散 units meant spares and service had to be simple and common.
Gas cost per crop cycle was above budget.
What we supplied & did
Fitted compact Riello 40 GS5 unit-heater burners across the zone banks.
Installed Dungs safety valve trains with leak test on each unit.
Added Honeywell flame detectors and pressure switches for safe automatic operation.
Balanced unit placement on site to remove the edge cold spots.
Measured results
What changed on the line
Crop zones heat evenly; edge cold spots and growth lag disappeared.
Complete combustion removed CO spikes versus the old heaters.
Common Riello/Dungs parts simplify spares across dozens of units.
Gas per crop cycle fell about 8%.
