Work begins on new lightweight regulator for H2 UAV Drone

Pressure Tech have secured an order for prototype lightweight regulators required to provide accurate and stable control of Hydrogen on a UAV drone. The design must weigh less than 300g and be able to reduce from 300bar to 0.5bar with stable control under decaying inlet conditions. The regulator must be; compact; accurate; reliable; strong; and lightweight! Our 16 years of experience in developing unique product for specific applications will contribute to the success of this challenge, with delivery of product expected in 8-10 weeks!

Problematic hydraulic regulators replaced with LF-690s

Following consistent resonating problems with one of our competitors hydraulic regulators on several offshore platforms, Pressure Tech received an order for 21 x LF-690 hydraulic regulators to retrofit units installed in HPU's throughout the Gulf of Mexico region. Recent testing of the LF-690 by a major system builder in the area confirmed the regulator provided stable control, even under initial start up conditions with 10,000psi differential pressure and up to 4GPM flow rates - without the need for any bypass!

$50k order for Appomattox Project secured and delivered

Pressure Tech's LF-690 regulators went through an intensive test program before being selected for use on the HPU's being supplied on the Shell Appomattox project, Houston. The system builder in Houston simulated various extreme situations that the pressure regulators encounter when operating the subsea valves, including initial start up and emergency shut down procedures with high differential pressures and various flow conditions. The stable and repeatable control (2%) witnessed by the system builder and their clients ensured the LF-690 was specified for this key project.

Pressure Tech awarded 98% in recent Supplier Audit by Michell Instruments Pressure Tech Ltd are delighted to announce that Michell Instruments Ltd, a key customer, has awarded us 98% in a recent Supplier Audit, stating that "the audit results exceed the expectations of Michell Instruments Ltd". Pressure Tech welcomed Andy Fox and Tracie Dawson from Michell to our factory on Wednesday 27th July, 2016. As a long-term supplier to Michell Instruments, we were pleased to show them our manufacturing facilities, quality procedures and corporate governance. The purpose of the supplier audit was to ensure that: 1) Pressure Tech has the fundamental ability to provide the required service to Michell Instruments, from a technical and commercial perspective. 2) Pressure Tech has the appropriate level of understanding and commitment to meet the applicable regulatory and legislative requirements when trading with Michell Instruments. 3) Michell Instruments and Pressure Tech share similar views in areas such as corporate and social responsibilities, quality, supply chain management and risk management. 4) A thorough review of Pressure Tech’s Quality Management System (QMS). A particular area of interest to Andy and Tracie concerned our new ISO Class 8 Clean Room and Oxygen Cleaning Service, which provides certified cleaning of components to ASTM G93 level C. We use this facility internally during manufacturing to customer requirements and offer this service on a sub-contract basis, including an oxygen cleaned certificate. "It is Michell Instruments Ltd., professional opinion that products and services supplied by Pressure Tech Ltd., are of a very high quality, and the management and control of systems and processes are carried out to a very high standard." Andy Fox—Technical Purchasing Controller, Michell Instruments. Michell reviewed our QMS, which is certified to ISO9001:2008 by DNV GL and also against ATEX Directive, and the additional requirements of EN ISO/IEC 80079-34 by CSA Sira. Michell were pleased to know that our range of electrically heated regulators are certified to the latest technical standards. Andy was especially interested in our Annual Management Review, describing it as ‘impressive’, further commenting generally that ‘Pressure Tech sets the benchmark for supplier standards’. Pressure Tech are working towards certification to ISO9001:2015 by June 2018 . We are delighted with such positive feedback from Michell Instruments.  Pressure Tech is a customer-centric business; we are proud of our facilities; and work hard to support our customers, suppliers and employees, to ensure successful growth for all. We can only achieve this through the excellent recommendations of our customers. Andy commented on the Michell Supplier Audit Report "It has the highest score of any company I have visited; you should all be very proud of what you have achieved, and we look forward to working with you for a long time ".
