A commitment to listen to our customers and a willingness to make the additions or changes in a reactor or pressure vessel that the customer may want or need. Approximately 40 percent of all the reactors and vessels we ship are modified in some way over-and-above the options listed in this website. Special valves, special head layouts, electrical leads, special stands, additional openings, unique motors, and non-standard materials of construction are just a few of the modifications we work with every day.

|
A commitment to maintain commonly used replacement and service parts in stock for same day shipment. |
|
|
An investment in modern machine tools and superior production management methods enables us to make available not only all of the options listed on the following pages, but also to handle custom orders for one-of-a-kind designs along with regular production orders on a routine basis. |
|
|
A commitment to new materials, manufacturing methods, research disciplines, and computer advances to continue our leadership position. |
|
|
A commitment to prompt and dependable delivery schedules for not only standard items, but also for custom equipment as well. Typical delivery time for reactors constructed of stainless steel is two to four weeks. For special alloys and custom modifications, plan for 4 to 8 week delivery. For systems or orders requiring extensive custom design work allow 8 to 12 weeks. Of equal importance over the life of your reactor is our commitment to maintain commonly used replacement and service parts in stock for same day shipment.

| The User’s Responsibility | |
All Parr reactors and pressure vessels are designed and manufactured with great care to ensure 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 the manufacturer. 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. 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. |
