Description
The Honeywell L91B1100 PropPressuretrol is a proportional pressure control engineered for precise steam pressure regulation in commercial and industrial boiler systems. Designed to modulate burner output in direct response to system pressure changes, the L91B1100 helps maintain consistent steam pressure across the full operating range of 5 to 150 PSI — reducing energy waste, minimizing pressure swings, and extending equipment life.
Key Features
- Proportional (modulating) pressure control for accurate, responsive steam pressure management
- Wide operating pressure range: 5–150 PSI to suit a broad variety of steam boiler applications
- Designed for use with modulating burner controls in commercial and industrial hydronic/steam systems
- Durable construction built to withstand demanding boiler room environments
- Reliable Honeywell engineering for long service life and consistent performance
Application
The L91B1100 PropPressuretrol is ideal for commercial steam boiler installations where precise pressure modulation is required. It works in conjunction with proportional burner controls to continuously adjust firing rate based on real-time system pressure, improving efficiency and comfort compared to simple on/off pressure controls.
