Gas charging test kit product range
Hydrotechnik UK has expanded its range of gas charging and testing kits. Five kits now make up the range from simple test and charging kits for under £200 through to the new World Wide Universal kit which caters for over 95% of the world’s accumulators. A new detailed catalogue showcases the entire range.
There are typically two types of accumulator design, bladder and piston. In both cases compressed nitrogen gas is used as a damper or energy store. Typically bladder style accumulators are used in low pressure systems and piston type in higher pressure applications. There are many manufacturers of accumulators and many different charging and testing valve connections utilised.
Ensuring that the pre-charge pressure is set correctly is the most important factor for both the correct functioning and ensuring accumulator life is not compromised. The care with which pre-charging is set and maintained is therefore an important factor. If the user tends to be careless about gas pressure and relief valve settings, or adjusts system pressures without making corresponding adjustments to pre-charge pressure, service life may be shortened and system performance compromised.
Hydrotechnik UK has specific kits for Minimess, Schrader or M28 x1.5 metric male ‘allen’ key accumulator valves are all catered for. One of the key aspects of Hydrotechnik’s kits is the range of pre-charge testing and charging devices available. The top of the range 5401 charging device allows Service Engineers to safely test and charge gas accumulators under full system pressure without the loss of gas or pressure.
