LIFE SUPPORT SYSTEM
The essential life equipment to support divers in the diving environment
Magma Boiler 1000 Unit with pump
The Magma Boiler 1000 with pump is a hot water unit which supplies hot water to the Saturation Diving System for bell diving operations when the related Magma SAT is out of order or unavailable for an emergency caused by interruption in ship power supply.
It is made up of a 1000-liter tank where the water is electrically heated to 58°C maximum and maintained with a low power consumption. This is the ideal solution to obtain a reserve of hot water, ready for use all conditions, with only the low power consumption required for the operation of the pump.
Sanitary Water Unit
The Sanitary Water Unit deliveries hot and cold water through two identical pumps. The great advantages of Drass solution are the simplicity, the reliability and the lack of long gas pilot lines from the chambers used in many systems. The water pressure is efficiently reduced at chamber level, on the exterior, and mixed according to the requirements of the divers.
The Sanitary Water System is dimensioned to supply different sanitary users at the same time with a flow higher than 80 liters per minute, allowing simultaneous use of the showers.
Sanitary Water Heater
Drass Sanitary Water Heater is a heating unit for sanitary water use, suitable for diving saturation systems. The equipment heats sanitary water using a 15kW heating element. The outlet port is connected to the Drass Sanitary Water Unit for pumping the hot water with high pressure.
Environmental Control Units
The system consists of a set of Environmental Control Units (ECUs) designed to control temperature, humidity and provide the requested life support redundancy to the Diving Decompression Chambers.
The Drass range of products is based on the well-known technology of a pressurized high head root blower. Drass introduced this configuration in 1970s and the current ECUs are sons of this proven and reliable solution.
The equipment proposed as primary environmental control unit is supplied in three versions. The traditional reliability and efficiency of the classic ECU can now be enhanced by a high-end Siemens control logic for the i-Life version, while new stainless-steel scrubbers and new interlocking mechanism systems are installed on all versions.
Assignment of the ECUs to the different locks:
Drass ECUs have heating and cooling capacity both rated more than 18 kW. This allows keeping an adequate reserve of power to ensure an excellent performance in dehumidification, heating and cooling, even when more locks are connected to the same ECU, beyond 30 m3 of total volume. The blower works with variable speed and can be regulated at the right speed for the chamber condition.
