wabtec HVAC retrofit off-site maintenance overhaul upgrade


Wabtec Rail, through the incorporation of Vapor Stone, has an internationally renown reputation for the supply of vehicle heating, ventilation and air conditioning (HVAC) systems. Our HVAC services cover everything from the design, manufacture and installation of new systems through to the upgrade and refurbishment of existing units. We are also able to provide a comprehensive spare parts and component overhaul service for not only Wabtec and Vapor Stone systems but also Westinghouse, Temperature, Stone Iberica and EBAC units. No matter what type of system you have, we have the skills and resources to provide exceptionally reliable, cost effective solutions.
Our engineering teams have considerable experience in the design of new HVAC systems for all types of rail vehicle ranging from locomotive cab air cooling to fully controlled passenger rolling stock air conditioning systems. Our engineers are available from the start of any new build contract to provide advice on air conditioning installations and vehicle interfaces. We can advise on system designs, heating and cooling capacities and associated power requirements. Systems can be designed as modular, self-contained units or split in-built systems sized to fit the available space.
For passenger rolling stock and locomotive cabs that lack air conditioning we provide full HVAC design, manufacture and installation packages tailored to suit your particular requirements. An example of our innovative retrofit solutions is the installation of air conditioning units for Class 165 diesel multiple units. Here we were able to produce a unit located within the overhead passenger luggage rack. For the installation of a cab air conditioning system on the HSBC Rail owned Class 455 units a unit was designed that located within the existing exterior vehicle front door with a magazine-loading air conditioning unit. The final product took up very little space and integrated seamlessly with the existing systems.
Increasingly we undertake maintenance work on our clients’ own sites, where our offsite teams provide a complete service to the very highest standards.
We have an enviable reputation in undertaking the overhaul and upgrading of HVAC systems. Our facilities include full strip and re-build, power wash, steam cleaning, shot blasting, spray application painting, polyester powder coating, refrigerant conversion, motor overhaul, compressor overhaul/re-manufacture, heater exchanger overhaul/renewal, control circuit overhaul/re-wire, full functional testing and full performance validation. In addition we undertake various system enhancements such as DC to AC motor conversion and control panel upgrades. AFTER-SALES SUPPORT Our after-sales support is second to none and includes technical back-up, health checks, service contracts, training and the supply of replacement parts for Stone, Westinghouse, Temperature and EBAC. Tailoring service packages to meet our clients’ individual needs, we focus at all times on quality and safety.
