The report is responsible for showing the pressure retaining materials that go into making the pressure vessel up to the code’s standard. The document is the official record that certifies that the vessel was tested and meets ASME code requirements. The vessels are only certified if they pass the testing done by a third party.

The third-party inspector is an Authorized Inspector, or “A.I.”. Wessels has an A.I. on the premises between 40 to 50 hours each week to inspect and test ASME compliant vessels. Wessels also has a Quality Control specialist on site during the testing. If manufactured together on the same day, tanks of the same model may go on the same data report, but different models are put on different reports.

If you would like to request a data report on a vessel you are purchasing or have purchased, you can request the document from our customer service department at 317-888-9800. Because each tank built to ASME code has a data report, Wessels does not charge a fee for the documents. However, if someone from your project team requests to be on site during testing and documentation, please be aware there is a fee to arrange. If you have further questions about data reports or the ASME code stamp, you can contact us on our website at www.westank.com or 317-888-9800.

GREENWOOD, IND. – Wessels Company, a leading manufacturer of pressure vessels and specialty hydronic equipment, is bringing innovative design improvements to its popular line of expansion tanks.

WessView®, a proprietary bladder integrity monitor “bullseye” that turns red when it comes in contact with water, is now standard on all Wessels expansion tanks. The monitor allows operating engineers and service technicians to quickly and easily determine if water has breached the internal bladder.

Wessels HVAC expansion tanks also include a new, integrated pressure gauge. Users will now be able to immediately read a positive indication of pressure charge on a gauge that comes standard on every unit. Connected to the bladder water side, there will be two openings on top of the flange. One opening can be used as a standard connection to the piping system, and the other can be used as a water evacuation point. Since the bladder is pre-charged, the air cushion in the tank will “squeeze” the water out. The user can isolate the tank from the system, evacuate the water from the tank and then check the tank pre-charge pressure on the gauge.

The new design also includes a coupling on the tank, air side, to allow easy installation of the company’s patented WessGuard® smart-tank monitor. The WessGuard® monitor includes a bladder proximity sensor and audible alarm that can be paired with a cellular unit that sends text alerts to your phone. The monitor is also compatible with energy management systems.

The new Wessels expansion tank is currently shipping. To learn more details on the next level intelligent expansion tank, click here.
