CTEK ROV Compensator Assembly

The CTEK ROV Compensator Assembly is a high-capacity positive pressure compensation system designed to protect large submerged oil-filled equipment from water ingress. With a substantial fluid volume of 3.47 Liters, this unit ensures that critical subsea components remain filled with incompressible fluid, maintaining a mean compensation pressure of 0.35 bar (5 psi).

Robustly engineered from aluminum alloy, stainless steel, and structural plastic, it is rated for depths up to 3000 meters. This assembly serves as a direct engineering equivalent to the Perry DWG-D60701 series, making it a reliable choice for industry-standard ROV maintenance and upgrades.

Key Features

High Volume Protection: Offers a generous 3.47 L fluid capacity to support larger subsea hydraulic circuits.

Positive Pressure Maintenance: Maintains a mean compensation pressure of 0.35 bar (5 psi) to actively block seawater ingress.

Safety & Expansion: Includes an adjustable pressure relief valve (normally set at 0.7 bar) to handle thermal expansion and prevent overfilling.

Smart Feedback: Compatible with a bolt-on analogue level sensor (Linear Position Transducer) for real-time 0-100% volume monitoring.

Scalable Architecture: Designed to be plumbed in parallel, allowing multiple units to work together for increased total oil capacity using a single sensor.

Industry Compatibility: Engineered as a direct equivalent to Perry DWG-D60701-001/002 models.
