Danfoss FPHB 5-LE Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Danfoss FPHB 5-LE is a specialized PTC (Positive Temperature Coefficient) oil preheater designed to optimize the viscosity and atomization of light fuel oil prior to combustion. By precisely regulating the oil temperature at the nozzle head, it ensures a highly uniform spray pattern, virtually eliminating cold-start smoking and significantly reducing soot emissions. Its self-regulating PTC element provides intrinsic safety against overheating, making it an essential efficiency upgrade for modern, environmentally conscious oil burner applications.

Selection Notes & Data Verification
The FPHB 5-LE page is structured for engineering comparison: confirm the product type, firing range, fuel type, operating mode, electrical supply, and safety approvals against the manufacturer datasheet before specifying the burner or component.
Burner.wiki normalizes product data for discovery and comparison, but final selection should account for combustion chamber backpressure, local emission limits, control sequence requirements, and site commissioning conditions.
