Heat exchangers for refrigeration systems
Refrigeration
For a heat exchanger manufacturer, industrial refrigeration is one of the most stimulating and complex sectors, due to the variety of operating conditions and technical challenges involved.
Phenomena such as frost formation on finned surfaces, material selection based on corrosion or low-temperature resistance, and thermal sizing for two-phase fluids require experience, precise design, and deep thermo-fluid dynamics expertise.
Switching from a gas cooler to a recirculation evaporator, for example, presents entirely different challenges:
In the first case, it is essential to maximize heat transfer on the gas side while maintaining low pressure drops even at high pressures.
In the second, proper distribution of the refrigerant in the circuits must be ensured, balancing them and introducing calibrated pressure drops along the liquid path to guarantee uniform evaporation.
Tailored thermal control solutions for every application
Within refrigeration systems, DBM designs and manufactures fully custom heat exchangers, optimized for each specific plant requirement, including:
Cooling coils with fin spacing up to 12.0 mm, even progressive, for glycol or brine applications
Direct expansion or recirculation evaporators, compatible with ammonia and other refrigerants
High-efficiency condensers and gas coolers
For materials, DBM offers all the most common combinations in the sector: from copper/aluminum to fully stainless steel (304 or 316) exchangers, and specific configurations for corrosive or high-pressure environments.
Defrosting systems are also available via electric heaters, integrated hot water or hot gas circuits, along with sloped or removable condensate trays.

AHRI Certification
PED Certification
DBM selection software
Our selection software allows easy sizing of reversible heat exchangers, automatically verifying performance during condensation and evaporation, selecting the most suitable materials for design pressures, and checking PED category compliance.
This is particularly important to ensure proper system assessment and full regulatory compliance in applications with high-pressure refrigerants such as CO₂, or “flammable” refrigerants like R290 and R32.
