The Kirby Morgan 37 Commercial Diving Helmet continues with a long tradition of providing the highest quality, and superior performance for commercial diving helmets.  The Kirby Morgan Commercial Divers Helmet 37 is very similar to the Kirby Morgan Superlite 27 Commercial Divers Helmet but it has a larger shell and includes the new Kirby Morgan Quad Valve Exhaust System.   The new Kirby Morgan Quad-Valve Exhaust System, which retrofits most previous Kirby Morgan Commercial Divers Helmets, has less breathing resistance than the older single valve exhaust while providing an extremely dry commercial diving hat. The Kirby Morgan Quad-Valve Exhaust Systemis recommended for commercial diving in biologically contaminated water. Kirby Morgan's SuperFlow regulator is a proven design that provides excellent breathing characteristics over a wide range of depths.

The Kirby Morgan Commercial Dive Helmet 37 is one of the most popular designs in the commercial diving world. It's considered the standard of the commercial diving industry. Choose the Kirby Morgan Commercial Diving Helmet 37 if you want a rugged commercial diving helmet with a traditional design.

Commercial divers can download the manual for the Kirby Morgan Commercial Dive Helmet 37 by going to the LINKS section.  This will take the commercial diver to the Kirby Morgan webpage where the manual can be downloaded chapter by chapter free of charge.

Warning: Before attempting any diving in any type of contaminated water, a complete commercial diving and topside course in hazardous materials emergencies should be completed. The commercial divers and the topside team must be properly trained and have the proper safety equipment. All commercial diving helmets and suits can leak water under certain conditions. Commercial divers should use extreme caution when diving in contaminated waters.

• Includes Kirby Morgan helmet bag 500901 and Kirby Morgan tool kit 525620.
• Side and Top Weights bring unsurpassed balance to the commercial diving helmet while providing for accessory mounting areas.
• Fiberglass and Carbon Fiber reinforced commercial diving helmet shell is hand laid up glass fiber reinforced thermal setting polyester (fiberglass) with carbon fiber reinforcement at key points for added durability. The commercial diving helmet shell is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor.
• Kirby Morgan Defogging Steady Flow Valve provides an additional flow of gas into the helmet for ventilation and defogging.
• Kirby Morgan Emergency (EGS) Valve supplies backup breathing gas to the commercial diver.
• Kirby Morgan Gas Supply Non-return Valve is Commercial Rated. It prevents loss of gas pressure in the event of commercial diver's umbilical damage.
• Kirby Morgan Rapid Change Modular Communications system is easily removed from the commercial diving helmet, repair or replacement of underwater communications parts is quick and trouble free. Kirby Morgan Rapid Change Modular Communications System is available with either a male Marsh and Marine style waterproof connector or a bare wire post connection.
• PositiveLock Latch System developed by Kirby Morgan in 1992 consists of two sealed PositiveLock pull pins which are pulled forward to release the neck collar and neck dam locking system. Even when the latches are released, the Oring sealed neck dam maintains a positive seal and will not allow the seal to be broken until the collar actually clears the commercial diver's shoulders, thus helping to prevent any flooding of the commercial diving helmet.
• Kirby Morgan Head Cushion gives the commercial diving helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.
• Air Train diffuses the incoming breathing air/gas onto the face plate to defog the lens.
• Kirby Morgan Silicone Oral Nasal Mask is made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
• Nose Block Device allows the commercial diver to block the nose to equalize ears.
• Kirby Morgan SuperFlow 350 is the all metal, fully adjustable, Commercial Rated demand regulator provides easy breathing and excellent performance with low pressure air compressors.
• Kirby Morgan Quad-Valve Exhaust System makes the commercial diving helmet very dry with no loss of breathing performance.
• Internal Adjustable Chin Strap, along with the adjustable neck pad on the locking collar gives the commercial diver a comfortable, secure fit.
• Adjustable Neck Pad is made from a scuff resistant elastomer which is attached to the yoke system. In conjunction with the spring activated front neck dam ring lock, it provides protection for the bottom of the Kirby Morgan Commercial Diving Helmet.

The Kirby Morgan 37 commercial diving helmet has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and, as far as applicable, the EN 250:2000, EN 250/A1:2006 and EN 15333-1:2008 (class B). It is fully CE marked with demand regulator SuperFlow 350 and oral nasals P/N 510-690 and P/N 510-747.

Temperature limitations

Use at water temperatures below 33°F (1oC) requires use of Kirby Morgan Hot Water Shroud (P/N 525-100) and hot water.

Note:

The Kirby Morgan Hot Water Shroud (Part #525-100) in conjunction with hot water to the commercial diver should be used whenever commercial diving operations are conducted using HEO2 at water temperatures less than 60°F (15.56°C) for the comfort of the commercial diver. Kirby Morgan DSI further recommends that the hot water shroud be used in conjunction with hot water to the commercial diver whenever commercial diving operations are conducted using air or mixed gas, in waters colder than 36°F (2.22°C) to reduce the possibility of demand regulator icing.

Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the divers exhalation coming in contact with the topside air temperature.

If diving where the water temperature is 36°F (2.22°C) or warmer but the topside air temperature is below freezing, (32°F (0°C) icing of the demand regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be run over the exterior of the demand regulator prior to water entry, if the hot water system is not used.

Only equipment certified and tested according to EN 250/E DIN 58 642 may be used with the Kirby Morgan 37 commercial diving helmet when conducting commercial diving operations in European EC compliant countries.

The commercial diver's umbilical assembly should be composed of good quality diving hose that meets industry standards. Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength member in a manner that will allow the strength member to receive all the strain. There are also good quality umbilicals available that are assembled at the factory using a twisted method which does not require marrying. Regardless of the system used, the commercial diver's umbilical is the commercial divers life line and should always be of excellent quality and maintained carefully.
