Intended Usage
This system has been designed for use as a high pressure reactor system. It has been
designed, built, and tested to strict physical and electrical standards. However, it is the user's
responsibility to install and operate it in conformance with local pressure and electrical codes.
If this equipment is used in a manner beyond its intended usage, the protection provided by
the equipment may be impaired.
User’s Responsibility
All Parr reactors and pressure vessels are designed and manufactured with great care to
assure safe operation when used within their prescribed temperature and pressure limits.
But . . . the basic responsibility for safety when using this equipment rests entirely with the user;
who must:
1. Select a reactor or pressure vessel which has the capability, pressure rating, corrosion
resistance and design features that are suitable for its intended use. Parr engineers will be
glad to discuss available equipment and material options with prospective users, but the final
responsibility for selecting a reactor or pressure vessel that will perform to the user’s
satisfaction in any particular reaction or test must rest with the user – not with Parr.
In exercising the responsibility for the selection of pressure equipment, the prospective
user is often faced with a choice between over - or under-designed equipment. The hazards
introduced by under-designed pressure vessels are readily apparent, but the penalties that
must be paid for over-designed apparatus are often overlooked. Recognizing these criteria,
Parr reactors and pressure vessels are offered in several different styles, each designed for
convenient use in daily operation within certain temperature and pressure limits, using
gaskets, closures and other elements carefully selected for safe operation within the limits
specified for that design. But in order to preserve the validity of these designs, all
temperature and pressure limits must be observed, and no attempt should be made to
increase these limits by making alterations or by substituting components which are not
recommended by Parr Instrument Company.
2. Install and operate the equipment within a suitable barricade, if required, with appropriate
safety accessories and in full compliance with local safety codes and rules.
All standard Parr pressure vessels are provided with either a suitable relief device or a
means to attach one (typically in the form of a plugged opening). When a pressure vessel is
delivered without a pressure venting device, it is the customer’s responsibility to provide
pressure relief in order to protect the operator and the equipment from destructive high
pressures. If you need more information or need help in selecting a proper relief device,
please contact Parr Instrument Company.
3. Establish training procedures to ensure that any person handling the equipment knows
how to use it properly.
4. Maintain the equipment in good condition and establish procedures for periodic testing to
be sure the vessel remains structurally sound.
Unpack Carefully
Unpack the equipment carefully and check all the parts against the, packing list. If shipping
damage is discovered, report it immediately to the delivering carriers. The vessel, motor, heater,
and temperature controller may be packed separately for convenience in shipping, but these
parts are easily reassembled. Examine the components closely for any loose parts or shipping
damage and be sure to check all layers of packing materials thoroughly so as not to overlook
any parts which might otherwise be discarded.
