Heat Exchangers

From its base near Newcastle, Heat Exchange Group (HEG) supplies the UK rail industry with a variety of heating devices

Our USP for existing rail operating companies is to offer a dedicated fast turnaround Clean, Test & Repair (CTR) service out of our Prudhoe service centre, so that planned and unplanned maintenance schedules in national service depots are kept to a minimum. When existing heat exchangers cannot be put back into service following a CTR, HEG can utilise its existing spare parts stock or inhouse manufacturing cell in Wakefield, so that customers are not waiting for replacement items.

Within the rail cell we have aluminium welders, fitters, machine operators and a delivery service, so that all requirements are covered.

We have manufactured heat exchangers for a range of locomotives over the years and some are listed below, however we are now seeing more enquiries for electric / battery powered vehicles:

• CL 66.

• CL 92.

• CL 150, 153, 156, 158/9.

• CL 170 / 175.

• CL 180 / 185.

• CL 220.

• CL 369.

With HEG we have an inhouse engineering department specialising in thermal and mechanical design solutions, for:

• New heat exchangers for new trains.

• Reverse engineering of old heat exchangers, so that new parts can be manufactured.

• Technical issues that need to be designed out.

• Maintenance issues that need to be design out.

Within the department we have a range of software packages and experience within the team to find alternative solutions.

To support customers further, we have the facility to manufacture one-off prototypes for testing both on and off the rail network, to ensure operating parameters are achieved.

HEG have the following accreditations to ensure quality is consistently maintained throughout the business:

• ISO 9001 – Quality system.

• ISO 3834 Part 2 – Welding Management.

• ISO 14001 – Environmental.

• ISO 45001 – Health & Safety.
