Why should I trust used equipment?

Honeywell now endorses the use of "recycled" parts to maintain legacy systems.  We believe that our extensive experience, thorough test procedures, replacement of aging components, and consistent focus on only Honeywell DCS gives us an advantage over all other sources of used Honeywell equipment, including Honeywell themselves.  If you have the occasion to come to Phoenix, ask Honeywell for a tour of their "Certified Recycled Parts" facility, then come over to WPC and take a tour of our facility, and do your own comparison.

We take great care to preserve the level of quality that you have come to expect from Honeywell equipment.  During a typical purchase of surplus equipment, we take possession of the equipment shortly after it has been powered down.  We transport the equipment to our warehouse using air-ride electronic vans - the same method of delivery used when the equipment was new. 

Once in our warehouse, the equipment is catalogued and stored until required for an order.  Static precautions are in force during all procedures where the equipment must be handled.  Prior to shipment, the equipment is thoroughly tested in our facilities to verify that a part functions according to specifications (see below).

Our newest equipment is sold first.  Our database of equipment on hand is sorted by date code, and we choose the most recent issue numbers available to fill an order, consistent with LCN, Experion, and release compatibility requirements.


What has been the performance record of Western Process equipment in the field?

While we do not guarantee against any failure, our equipment has an excellent reputation among users.  We are often told that users can't tell the difference in performance and reliability between our equipment and original manufacturer's equipment.   We have a very low rate of warranty returns. For feedback directly from some of our customers, call or fax our office for references.


Do you modify equipment prior to selling it?

We believe that the best level of quality and reliability is maintained by minimizing handling of the equipment, so we sell much equipment without any modifications.   There are some high-demand items, however, where certain components are know to deteriorate over time.  We have identified components that we know to be susceptible to age-related failures, such as the electrolytic capacitors on regulator boards and output boards, relays on the thermocouple mux boards, relays on CMOS memory boards, etc.  We replace these aging components with new components meeting or exceeding original specifications. 

 
What about revision levels?

We purchase equipment with a range of age and revision levels.  Our newest parts are always selected for sale first.  Our oldest parts are scrapped, though in some cases they have operated for over 20 years without problems.  We identify minimum acceptable revisions for a part, and only ship parts meeting these minimum revisions.  Minimum revisions may be required for LCN compatibility or for compatibility with the latest software release.  If you have a specific requirement related to the revision of a part, inform us of your requirements and we will tell you if we have the required equipment available. All Data Hiway equipment that we select is LCN compatible, unless you request otherwise.

How do you test your parts?

All parts are tested for a minimum of 48 hours prior to shipment.  We have a full-time test facility running equipment including all TDC 2000 Hiway boxes, LCN nodes, and UCN equipment including HPM, APM, PM and LM.  Each part is tested for functionality appropriate for that part.  Where calibration is relevant, the part is calibrated and monitored for drift.  Where a part includes multiple I/O channels, each channel is tested for proper performance.  Where diagnostic software is available to diagnose or exercise a part, it is run on the part.  Our test procedures allow us to provide  parts with performance equivalent to newly manufactured parts.
