Phoenix 85 Series Flame Scanner SIL3
The Fireye Phoenix Series 2 type 85UVF/IRF flame scanners, designed for reliable flame detection in burner management systems. These microprocessor-based devices utilise a solid-state flame detection sensor, ensuring precise and consistent performance. The Phoenix flame scanners incorporate an internal flame relay with automatically set ON/OFF thresholds, eliminating the need for a remote flame amplifier or flame switch. Built to meet SIL3 safety standards, these scanners deliver dependable protection and operational efficiency.

Phosphate Esters
Phosphate esters are 100% active anionic surfactants which are produced as the free acid by either of two chemical routes. Phosphate esters are highly versatile surfactants offering a wide range of properties and applications. As such they are used widely in emulsion polymerisation, textile auxiliaries, maintenance chemicals, metal finishing, and many other applications. They are especially useful in household and maintenance cleaning products, where high active heavy duty products are required.
