Hengel finalises R455A testing for one of its product lines
A
key player in the bakery and pastry industry for more than 35 years, the R&D department is constantly specialising and innovating to meet the needs of professionals in this sector, and also sectors where similar equipment is used.
Hengel is recognised as a specialist player in the design of premium refrigeration equipment for freezing, rapid cooling, preservation (chilled and frozen) and controlled fermentation intended for the bakery-pastry industry. Since then, the company, which is now managed by Denis Bigot, has been targeting the food service sector such as artisan bakeries, mass distribution and industry both in France and internationally.
In order to reduce its carbon footprint, in 2012 Hengel implemented the Blue Pulse approach which involved developing and continuously improving the performance of its products with constant research based on energy savings, sustainable development and eco-design.

Hengel controls the entire manufacturing process of its refrigeration equipment: from design to industrialisation, including sheet metal work, injection of polyurethane foam for the insulation of the chamber and the refrigeration part of the equipment.
To improve the efficiency of the equipment, three factors are key, as Dr. Younes Matar, technical and research and development director at Hengel, reminds us – temperature, hygrometry and aeraulics.
In order to achieve the performance of a machine, refrigerants also play an important role, particularly in terms of efficiency and since the introduction of F-Gas.
"Choices had to be made on transition refrigerants to quickly replace R-404A in the face of the quota mechanism put in place, which led to problems with availability and price increases. Mindful of this impact, we started to work in parallel on long-term solutions but it was not
easy because we are the last link in the chain and depend a lot on the strategy of component manufacturers (compressors, expansion valves, evaporators, etc). In deep-freezing, for example, it was difficult to reach an evaporation temperature of -42°C with the refrigerants on the market. Today, we are starting to see things more clearly and we can make strategic decisions and work on the launch of our future ranges," stresses Dr. Younes Matar.
The introduction of new technologies such as CO2
, A2L or A3 classified refrigerant fluids also requires them to review the design of their machines to comply with legislation, to carry out tests to find out the behaviour and performance of the new refrigerants in their various equipment and to study the impacts on the manufacturing line. To do this, dedicated resources are required.
