Crafting comfort as the Supplier coordinator

HVAC sub-system engineering is a niche skill for Quest Global. It is a system designed to ensure passenger and driver comfort. 

Based on the geographical climate conditions range identification (min/max) we gauge the HVAC performance and define the HVAC cooling capacity. This capacity gives the idea for the lead time for components like compressors and evaporators. Weight optimisation is a major challenge for original equipment manufacturers (OEMs).

OEMs have limited resources, and so often approach Quest Global to get help from our expert engineers.

Because HVAC is a built-to-spec component we can support the writing of specifications, coordinating with the suppliers to ensure everything is environmentally safe and low maintenance.

Designing for exact fitment is the challenge OEMs face for HVACs. To build as per the exact dimensions and specifications in one operation, they need a coordinator for all the suppliers. 

We gather all the previous documents from the OEM and, based on the climatic condition range, we develop the scope of work.

Because HVAC is a built-to-spec component, we support the writing of specifications – ensuring the optimum cost, weight, and efficiency whilst coordinating with the supply chain throughout. 

As a pioneer in the field of engineering solution providers for rolling stock HVAC sub system, Quest Global has already supported a major railway giant for multiple projects. All our solutions are First Time Right (FTR), with a customer-centric approach. 

We believe Quest Global deliverables are the most affordable and cutting-edge to meet global customer requirements in the field of HVAC sub-system development.
