Gas Treatment in the Marine Industry
Onboard commercial vessels, gas treatment covers a broad range of applications - from purifying compressed air that powers instrumentation and control systems, to managing exhaust gas emissions and protecting cargo spaces from toxic gas ingress. Contaminated gas streams are a leading cause of instrument failure, unplanned maintenance, and accelerated corrosion in engine rooms and below-deck systems.
Regulatory pressure has made gas treatment a compliance priority as much as a maintenance one. Under MARPOL Annex VI, vessels must meet strict limits on sulfur oxide (SOₓ) emissions - either by switching to low-sulphur fuel or by operating an approved Exhaust Gas Cleaning System (EGCS). Beyond exhaust management, tightening port-state inspection standards mean that compressed air quality, condensate discharge, and gas safety systems aboard are under greater scrutiny than ever.
For marine engineers and fleet managers, the practical challenge is specifying the right filtration grade for each application - protecting sensitive equipment without over-engineering the system. That is where Insatech Marine's technical expertise and Parker product range make the difference.
Our Gas Treatment Products
As an authorised Parker Hannifin distributor, Insatech Marine supplies the full Parker gas treatment range - including genuine replacement elements - with fast worldwide delivery and personalised technical support.
Parker Domnick Hunter
Parker domnick hunter is Parker's specialist compressed air and gas filtration division, certified to ISO 8573 and DNV standards. Key products for marine applications include:
- OIL-X Evolution coalescing filters - remove oil aerosols, water, particulates, and micro-organisms from compressed air streams, achieving oil content below 0.01 mg/m³ and particle removal to 0.01 micron
- SCE-HB sterile compressed air filters - absolute 0.01 micron retention in hydrophobic PTFE media for microbiologically sensitive applications
- Desiccant and refrigerated air dryers - prevent moisture corrosion in instrumentation and control systems
- Oil/water separators - compliant condensate treatment for vessels operating in port and coastal waters
Parker Hiross - Hyperfilter Series
The Parker Hiross Hyperfilter range eliminates dirt, oil, and moisture from compressed air systems in aluminium and carbon steel housings built for marine environments. Five filtration grades cover every application:
| Grade | Type | Application |
|---|---|---|
| P | Coarse pre-filter | Bulk liquid and pipescale removal |
| S | General coalescing | Standard compressed air quality |
| Q | High-efficiency coalescing | Sensitive instrumentation and process control |
| D | Dry particulate | Solid particles and micro-organisms from dry gas |
| C | Oil vapour removal | Highest-purity gas streams |
Insatech Marine stocks genuine Parker Hiross Hyperfilter replacement elements for all grades, supplied to OEM specification.
