WELCOME TO STEPHEN BALARAM ENGINEERING PVT. LTD. HIGH PRESSURE ENGINEERING DIVISION

PORTABLE OXYGEN GAS CHARGING UNIT Haskel Oxygen Gas charging units provide a fast efficient and economical method of charging, or topping up gas pressures in devices such as:
In-flight Oxygen Gas Systems.
Breathing Apparatus.
Commercial Divers Gas Cylinders.
Military Divers Gas Cylinders.
The illustrated portable booster systems are designed to be lightweight & practical. Clearly labelled controls to ensure simplebut safe operation.
The units enable optimum use of commercially bottled oxygen gas down to aresidual pressure of 7 bar.
Careful selection of materials ensure maximum operator safety.

Gas charge pressures of up to 200 bar are achieved using stainless steel process equipment. Gas charge pressures up to 350 bar can be achieved using Monel and/orbronze process equipment.
The units are supplied cleaned for oxygen gas service with protective plugs to prevent dirt ingress when not in use.
Apart from compressed air, no other power supply is required to operate these unitsmaking the suitable for operation in any location.

* Actual flow capacity varies with gas inlet pressure, air drive pressure and volume and outlet pressure.
Descprition
Each unit comprises a water proof, robust, injection moulded case, in which is mounted the following equipment :
* Haskel Air driven oxygen gas Booster. * Air inlet to air drive controls comprising, - Air drive filter, Air drive pressure regulator, Air pressure gauge, On/off speed control valve. * Inlet oxygen gas bulkhead with plug to prevent dirt ingress. * Inlet 5 micron gas filter. * Inlet pressure gauge (gas safety pattern). * Outlet Pressure Gauge (gas safety pattern). * Outlet relief valve. * Outlet isolation valve. * Outlet vent valve. * Outlet gas bulkhead.
All suitably piped, cleaned and tested for oxygen gas service
Features
Haskel air driven gas boosters offer many advantages over electrical driven high pressure compressors:
Ability to stall at any predetermined pressure and hold this fixed pressure without consuming power or generating heat. No heat, flame or risk of spark. Infinitely variable cycling speed (flow rate). No limit or adverse effect to continuous stop/start applications. Gas booster seals are self lubricated requiring no external air lubricator Reliable, easy to maintain, compact and robust.

OPEN FRAME DESIGN The Haskel oxygen hand booster has been developed for the manual charging of life support and resuscitation cylinders in areas where there is no power supply (electrical or compressed air) available
The hand booster incorporates many of the key features of the standard Haskel air driven gas booster range within the design as follows
KEY FEATURES
• Double acting for effective operation
• Balanced piston design uses incoming gas to assist the pumping operation
• No risk of contamination into the oxygen gas sections
• Self lubricated oxygen seals require no lubrication
• Patented Haskel sealing arrangement in the high pressure sections ensure long working seal life
• Double handle arrangement for one or two man operation
• Portable and lightweight
• Compact and durable
• Reliable and easy to maintain
• Totally self contained unit requiring only two connections
◊ one gas input ◊ one gas output
• Capable of boosting oxygen gas from supply cylinders to 5,000 psi

Description

Haskel Oxygen Hand Booster Part Number J23515-2
At the heart of the unit is a positive displacement double acting reciprocating booster pump driven by either one or two operators. At the commencement of the suction stroke the inlet non-return valve will open allowing gas into the gas barrel. On the discharge stroke the inlet check valve will close and the outlet check valve will open. This will force the pressurised gas into the discharge pipe-work. The maximum pressure capability is dependant on the force applied by the operator (s) and the gas inlet pressure available.
If a high gas inlet pressure is available the work needed to complete the gas transfer is reduced. Built into the booster are:
◊ Inlet gas filter,
◊ Outlet Relief valve
◊ Outlet Pressure Gauge
◊ Outlet Stop & Vent valves
◊ Inlet and outlet bulkhead connections with dust caps
The unit comes suitably piped for oxygen gas service and is set for charging to 200 bar unless requested otherwise.
