OB200 was designed to provide the industry with a cost effective, environmentally superior and robust workhorse.

Product Overview

ENVIROSOL OB200 is fully compatible in all proportions with Brayco Micronic fluids and can be used to ‘top up’ existing systems where a stronger focus on cost and/or environmental discharge is required. OB200 can be used in both open and closed systems.

ENVIROSOL OB200 has undergone qualification across a wide range of industry equipment, along with a massive compatibility test program in relation to metals and elastomers commonly used in subsea systems.

ENVIROSOL OB200 is environmentally acceptable for use in OSPARCOM countries boasting a 'Yellow' status (Norway), and OCNS Class E (UK).
