Curvetech® compensators

Suitable for a wide range of subsea vehicles and applications

Based on tried and tested technology, Curvetech® compensators are used throughout the SMD vehicle range. Our compensators have been developed and optimised over many years by highly experienced engineers. Applications vary from vehicle reservoirs to compensation of electrical boxes and other housings. The latest models are available in a range of sizes and options to suit all systems, allowing for ease of use and efficient maintenance. The new generation models (2.75l, 3l & 6l sizes) provide a clear view of oil level and condition. Spot entrained dirt, air and water in your system at a glance, ensuring issues are recognised and fixed quickly, preventing further consequential damage.

PRODUCT FEATURES

Wide range of size options

Size ranges from 0.5l to 100l and customisable connection ports.

Transducer options available

4-20mA or 0-10V - with Burton, Seacon, Subconn or Impulse connectors. Others available on request.

Mounting kits available

Ease of operation and maintenance, tried and tested on SMD ROVs. Designed for simple integration.

Integrated safety features

Safety pressure relief valve. Additional integrated air bleed point for operational simplicity.

Reliable and rugged design

Curvetech® compensators are constructed from stainless steel and engineering plastics to ensure maximum corrosion resistance. An internal rolling diaphragm arrangement is used to smoothly transmit pressure changes and ensure leak-free usage, and a compensating mechanism is complemented with springs of various rates to match the required application. Transducers are available for all compensators for remote monitoring of the fluid level.
