All our work is compliant with all relevant BS EN standards.

We can offer One-off design and Build Projects, Prototype Design and Development, Sub Contract Product Development and Batch Production.

Design and Engineering

Our clients provide a list of requirements for their process and we work with them to define a technical specification. Thereafter our team will manage the entire development and design tailored for our customer’s specific requirements. With our wealth of experience and knowledge we produce a detailed design which is regularly reviewed with our customer throughout the process.

We have our own in-house professionally qualified Engineering Team who work with many tools including:

  • 3D Technical Drawing Packages
  • 2D CAD and schematic drawings
  • MRP system to create and manage Bills Of Material (BOM)
  • Electrical Drawing Package
  • Custom Built Engineering Design Software

  • Interface with other plant over all common protocols
  • Remote access via hard wired or internet connection

Test and Inspection Controls

GRE are certified to ISO9001 , and this drives all aspects of our quality systems. All machines are tested against a prescribed test procedure to ensure that machines leaving the factory perform reliably and accurately.

From our factory in the UK, we can simulate any electrical supply worldwide, meaning that machines tested in our factory can be dispatched anywhere in the world with confidence.

We invite our customers to visit our factory when their machines are on test in order to witness the testing and carry out additional testing to their satisfaction. Meticulous records are kept of the testing process.

Installation and Commission

GRE are able to support our customers at the commissioning stage and beyond with our external support team, including tailored support packages which incorporate training and ongoing support if required.

Sub Contract Product Development

GRE can provide a complete out-sourcing solution to your requirements.  We can design and manufacture a prototype of any specialist heating/cooling equipment, and then provide a full package of drawings, detailed BOM, including suggested suppliers and prices, and hand the production back to you.
