This unique position means we understand the market requirements, as well as the challenges our customers face, at every level. That’s why our range of Heliox high pressure air compressors are engineered to meet the rigorous demands of a variety of specialist applications, including:
Marine / Offshore
Navy / Defence
Professional Dive
Reavell provides a variety of configuration options that allow our equipment to be tailored to meet our customer’s specific needs. Depending on vessel requirements, our range of machines can be configured for either dedicated or dual-role operation.
Our range of standard configurations include:
• Dedicated Heliox transfer duty• Dedicated Heliox reclaim duty• Dual Heliox transfer & reclaim• Dual Heliox transfer & breathing air duty• Dedicated breathing air duty
Other configurations can be considered on request.
Each package is equipped with a comprehensive standard specification list, which typically includes:
• Low lift combined suction / delivery valves specifically for low density gas operation
• Integral inter and aftercoolers with separators on each stage of compression
• Automatic isolating valve on cooling water inlet
• Electrically controlled automatic unloader/drainage (solenoid valve operated)
• Forced lubrication system “spin-on” replaceable filter
• Oil pressure gauge
• Low oil pressure protection switch
• Special gas type crankshaft oil seal assembly
• Gas type oil filler assembly • Gas type crankcase breather piped back to suction
• Corrosion rods and safety bursting disc in cooling water jacket• Combined temperature indicator with combined cut-out switch on 3rd stage delivery
• Combined temperature indicator with combined cut-out switch on final delivery
• Compressor non return valve
• Controlling pressure switch, (supplied loose)
• Drive arrangement – vee belt drive or direct coupled according to m/c size / type
• TEFV, IP55 electric motor• Marine type (captive) anti-vibration mounts
Compressor packages are also commonly supplied with a range of ancillary equipment, such as:
• Starter / control panel
• Gas clean-up filtration pack
• CO (carbon monoxide) monitor (optional – supplied loose)
• O2 (oxygen) monitor (optional – supplied loose)
Note: Standard specification sets assume direct cooling from a suitable fresh water supply on-board. Alternatives for direct sea water cooling and cooling via sea water / fresh water heat exchanger systems are available on request.Standard instruments are conventional switch devices. As an alternative, transmitter devices (4 – 20mA) can be quoted for on request. Additional instrument options, such as water temperature indicators and cooling water flow-switch are available on request.The “Standard” specification listed above typically indicates the scope of supply for a dedicated Heliox transfer compressor. Machines that are configured for other duties may differ slightly in scope of supply (usually related to gas / air inlet equipment)
Each fully assembled package is also equipped with a range of additional features that are designed to maximize safety, performance, and ease of use, including:
• Gas inlet O2 monitoring / trip (O2 content max allowed is 21%) • Carbon monoxide monitor / trip• Breathing air filtration systems • Plug and play unit
• Complete packages design approved from DNV* / ABS• Type approval for compressor block from DNV*• Available in vertical and horizontal configuration to meet footprint requirements
*Products approved by this certificate are accepted for installation on all vessels classed by DNV GL
