Danfoss has introduced three innovative brazed plate heat exchangers designed for residential propane heat pumps.
Leading the lineup is the H39L-EZU, which boasts a low channel volume and minimal water-side pressure drop, enhancing efficiency.
The H62L-CZ features an asymmetric plate design, specifically tailored for R290 reversible heat pumps.
Completing the trio is the HDW30-C, an ultra-safe solution for condenser or desuperheater applications, ensuring that fluids remain securely separated to prevent any cross-contamination.
Danfoss provides heat pump manufacturers (OEMs) with expert support in comfort and industrial applications, encompassing system design, performance optimisation, simulation tools, testing facilities, and manufacturing simplification.
OEMs can accelerate the green transition with the new and extended brazed plate heat exchanger range for residential and light commercial heat pumps.
Commenting on the extension of the brazed plate heat exchanger propane portfolio, Mads Pinnerup, head of Brazed Plate Heat Exchangers, Danfoss, said the products are designed to advance energy efficiency and lower the carbon footprint of heat pumps.
“As we continue to evolve with the changing energy landscape, propane heat pumps offer a forward-thinking approach to cleaner, more efficient energy use in both residential and commercial applications,” he said.
H39L-EZU evaporator
The new propane H39L-EZU evaporator can function efficiently as an evaporator or a condenser, providing users with a state-of-the-art heat transfer solution for your reversible system.
In addition to Micro Plate technology, the H39L-EZU has a special mixing chamber that creates excellent conditions for two-phase refrigerants and features superheating regions that enable optimal phase shift.
This results in great refrigerant distribution with no degradation on part load and means that the heat exchanger is less sensitive to the refrigerant’s connection size.
H62L-CZ condenser
The H62L-CZ is a condenser optimised for use in R290 heat pumps and chillers. The new asymmetric Z-design Micro Plates has different flow channels on the refrigerant side which improve heat transfer, reduce the amount of material used and minimise the pressure loss on the water side.
HDW30-C & HDW44-C double wall condenser / desuperheater
HDW30-C and HDW44-C are double wall heat exchangers designed for applications where the liquids are not allowed to mix.
A double wall heat exchanger prevents the primary flow to be mixed with the secondary flow if there is an internal leak in the unit by leading the leaking liquid out of the heat exchanger.
