HVAC

Leader in silver-containing brazing consumables for the HVAC&R industry

Industry and megatrend

China, Mexico, Middle East and Europe are the main markets for HVAC&R brazing. As a competent partner for brazing applications Fontargen Brazing serves customers in refrigeration, HVAC systems and vehicle air-conditioning as well as in the heating heat pump technology. The industry trends are taken into account in product selection and product development:

  • Ongoing expansion of fast food chains with new equipment needed at smaller locations for cooling large volumes of food.
  • Market driven by the increase in frozen food consumption. Need to increase the cold chain quality in order to insure high hygiene standards.
  • Avoid breakdown and loss of stocks and insure the concordance regarding all National legislations for food safety standards.
  • Reduce production costs by optimizing brazing and post brazing processes.
  • Air-conditioning of buildings, offices in cars, a.s.o. to be seen as standard.
  • Use of aluminum as new base material for micro-channels heat exchangers (HX). The aim is to reduce refrigerant charge in the HX, increase its surface by minimizing its weight, allow a higher efficiency, a lower refrigerant charge and a smaller footprint
