COMPRESSOR PROTECTIVE DEVICES

VIBRATION ELIMINATORS

The function of a Vibration Eliminator is to absorb compressor

vibration to reduce the risk of damage to system equipment and

pipework.

Applications

A Vibration Eliminator can be installed in both the suction and discharge lines

of air-conditioning and refrigeration systems.

Vibration Eliminators are suitable for use with HCFC and HFC refrigerants

and their associated oils, as well as other industrial fluids non-corrosive to

stainless steel and copper.

Each unit is constructed of a

deep pitch corrugated hose covered with a stainless steel braid. The hose

and braid are reinforced by ferrules at each end and connected to copper

tube ends by a high temperature braze alloy.

Technical Specifications

Maximum working pressure = see table below

Allowable operating temperature = -40°F to +212°F (-40°C to +100°C)

Vibration Eliminators are USR and CNR recognized by Underwriters

Laboratories, Inc. Additionally, Vibration Eliminators 1-3/8” and larger are CE

marked in accordance with PED.

Materials of Construction

Each model consists of a stainless steel corrugated hose covered with a

stainless steel braid. The ferrules are stainless steel and the tube ends are

made from copper.

6. The ferrule and start of braid must be wet-ragged for brazing, to prevent

overheating and subsequent damage. All excess flux must be removed to

prevent corrosion and premature failure.

Installation - Notes

1. The Vibration Eliminator should be fitted as close to the compressor as

possible and must be installed in a straight line. Vibration Eliminators are

not designed to compensate for pipework misalignment.

2. Care should be taken to allow sufficient space for the Vibration Eliminator

to avoid static compression or tension, after brazing in place. Vibration

Eliminators are not designed to absorb axial or torsional stress.

3. Vibration Eliminators should be installed perpendicular to the direction of

vibration. When vibration exists in two planes, two Vibration Eliminators

should be used. Refer to Fig 1 and 2.

4. For optimum absorption of vibration, the refrigerant line should be

anchored at the end of the Vibration Eliminator furthest from the vibration

source.

5. Take special care to install Vibration Eliminators horizontally when used in

suction lines or where operating temperatures are below freezing point.

Condensation may form on the outside of the unit and if installed

vertically this may accumulate in the lower braid collar. In subsequent

freezing this may deform and destroy the unit. If vertical installation is the

only option, or indeed if condensation is possible with horizontal

mounting, the entire flexible section, ferrules and braided hose, must be

covered with a watertight synthetic material e.g. a heat shrinkable PVC

sleeve.
