Transformer Rectifier Unit Services

One of our main priorities is to be in discussion with each client throughout the design and manufacturing processes of their item. We invite clear input that helps us to reach your ideal solution. As well as working with your specifications to produce the perfectly suited end-product, each TRU that we manufacture also includes full working drawings, itemised component lists and operating instructions in whatever language you require.

We can also include a host of custom features with each transformer rectifier unit, able to meet each client’s exact design needs. We have full confidence that our in-house ethos for excellent service, allied with our experience in the industry, allows us to provide the highest level of quality and safety available.

Each of the TRUs we produce is completed at our Liverpool-based workshops, with every part of the design and manufacture done in-house to guarantee the work can be monitored and keeps to the highest standards. Every member of our technical staff has been selected because of the skills and experience they possess, allowing us to offer a wide range of bespoke design options. We’re fully confident that you will receive the exact TRU that your need, a piece of equipment that gives you the peace of mind of knowing that you are operating a high-performing, efficient, durable and safe unit.

Additional Support

We’re equipped to deal with a wide range of individual requests, with our accomplished technical staff able to helping you produce the exact transformer rectifier unit (TRU) you need to suit your particular environment. We make it our mission to provide high quality design, manufacturing and customer service standards, allowing every single client to be fully confident in the finished product they receive, both in regards to quality and safety standards. All of our TRU manufacturing processes conform to BS EN ISO 9001:2000 standards. In addition, we also regularly subject all of our manufacturing standards to internal and external audits. We do so to ensure that we constantly maintain our in-house commitment to excellence, giving each client the excellent service that they deserve.

With our wealth of experience manufacturing transformer rectifier units for a wide variety of different operating environments, from military to offshore, rail to marine, we are able to understand the exact manufacturing needs of your setting. We can provide you with detailed advice on the specific needs posed by operating in different settings. This allows us to ensure that every single TRU we manufacture offers protection against hazards such as humidity, vibration, dust or gas.

Our helpful support team are available from Monday to Friday on 0151 486 6760, and we also offer rapid lead-times to all of our clients. We understand how helpful it is to know that your TRU can provide safe and durable use, but that in the rare case where there is any disruption, it can be fixed in the quickest time possible. We provide this to every client, offering support whenever and wherever needed.
