BUILDING BASE ISOLATION - CDM-ISO-CAS-BOX

BUILDING BASE ISOLATION - CDM-ISO-CAS-BOX
CDM-ISO-CAS-BOX Pre-Compressed Elastomer Boxes are used to isolate buildings where the required natural frequency is 6Hz to 10Hz. They consist of elastomer pads inside reinforced steel boxes which are pre-compressed to a specified load. The advantages of pre-compressed elastomers over simple elastomers are as follows: • The elastomers are pre-compressed to a percentage of the overall supported mass (say 80%) therefore minimising deflection during construction (deflection only occurs after the precompression has been exceeded) - this is especially important when low frequency solutions are required as this results in high deflections • The boxes can be neutralised, replaced or inserted after construction. It is essential, however, that all boxes are accessible and this should be considered in the scheme design phase of the building. >>>

STEAM AND POCESS GAS VENTS HUSH PUP VENT SILENCER

STEAM AND POCESS GAS VENTS HUSH PUP VENT SILENCER
The Flo-Dyne Limited HUSH PUP is a non-packed, reactive silencer. It works by expanding the incoming flow through many small holes. This expansion creates a reduction and frequency shift in the vent noise. By correct selection of hole size, spacing and pattern this reduction can be optimized to produce an overall quieting. This simple, yet effective silencing concept has been tested and proven in over 4,000 applications as a component part of Flo-Dyne Vent Silencers. >>>

EXHAUST CLEANER

EXHAUST CLEANER
Many air operated pumps require a small amount of lubrication to operate properly, this oil is introduced at the pump inlet and is atomised over the pump internals. The excess oil is expelled from the exhaust muffler along with any other particulate in the air supply. If the pump is being operated in an area where people are working they can involuntarily inhale these atomised liquids. also in clean environments a film of oil can be deposited on surfaces. To eliminate the majority of particulate, exhaust cleaners are fitted to the pump air outlet and collect them. They are also useful when pumping dangerous or expensive products as often with diaphragm failure liquid can be forced to the pump exhaust. The above equipment should be installed with every pump installation individually and as the cost is less than that of an air valve, it is probably the best preventative maintenance you can give your production. >>>

BUILDING BASE ISOLATION - CDM-ISO-CHR

BUILDING BASE ISOLATION - CDM-ISO-CHR
CDM-ISO-CHR Simple Spring units are used to isolate buildings where the required natural frequency is between 4 and 5Hz.

BUILDING BASE ISOLATION - CDM-ISO-CHR-BOX

BUILDING BASE ISOLATION - CDM-ISO-CHR-BOX
CDM-ISO-CHR Pre-Compressed Spring Boxes are used to isolate buildings where the required natural frequency required is 2.5Hz to 4Hz. They consist of springs inside reinforced steel boxes which are precompressed to a specified load. The advantages of pre-compressed springs over simple springs are as follows: • The springs are pre-compressed to a percentage of the overall supported mass (say 80%) therefore minimising deflection during construction (deflection only occurs after the pre-compression has been exceeded) • The boxes can be neutralised, replaced or inserted after construction. To achieve this all boxes must be accessible. This should be considered in the scheme design stage of the building • By nesting springs (small spring inside a big spring) the CDM-ISO-CHR pre-compressed spring boxes can be fine tuned to take specific loads • The spring boxes can be compressed to the block limit of the spring without significant plastic deformation to the box • The elastomer layers (EL) either side of the steel box elements minimise the effect of the spring coil resonances, and provide a more uniform load transfer between the contact surface with the structure below and above >>>
