ERS 350 Mag Environmental Regeneration System

The ERS 350 Mag is a quiet, reliable and multi-configurable external gas regeneration system for Saturation Diving. The unit consists of a robust frame/skid, located within an ergonomic cabinet with access hatches. The ERS350 Mag is designed to circulate gas from inside the chamber environment and through a scrubber. The unit also controls the humidity by the condensation of water vapour, and provides heating and cooling to the chamber environment which is achieved via a heat exchanger and a cooling heat exchanger (hot and cold water sourced separately and not part of the regeneration system). The ERS 350 Mag features a hermetically sealed high efficiency, low maintenance blower. The blower motor lies external of the pressure system and drives the blower via a magnetic coupling. This ensures the chamber gas is not exposed to the heat expelled from the motor. A local user control-centre in the form of a touch screen Human Machine Interface (HMI) is conveniently positioned for easy access on the cabinet. The interface can be easily integrated with other remote monitoring and/or control devices (eg. HMI, SCADA) where required. The operator is able to easily view the following typical parameters:

  • Chamber Environment Temperature and Humidity
  • Regen Blower Speed
  • Regen Inlet and Outlet Gas Temperature and Pressure
  • Hot and Cold Water Inlet Pressure and Outlet Temperature

A local audio and visual alarm (with error pop up message) would be triggered in the event that any of the process parameters are exceeded.
