Oil-Air Ratio Regulators MRO

A Honeywell Hauck product. The MRO regulators support applications requiringm wide turndown and/or low flow rates and repeatability. The MRO is engineered to function properly over a wide range of air pressures and may be used on either single or multiple burner applications. A constant oil pressure is required at the inlet of the regulator. The MRO provides an automatic and simple means of maintaining this ratio even at extremely low flow rates.

Features & Benefits:

• Accurate and repeatable low flow rate sensitivity
• Wide turndown capability
• Easy to maintain
• Wide capacity range
• Provides automatic and simple method of maintaining air/oil ratio
• Requires constant oil supply at 45 – 65 psig (310 – 450 kPa)
• Rugged modular construction
• Overpressure safety relief valve
• Handles No. 1 through No. 6 fuel oil
