Microchannel Fluid Coils Deliver 500 kW Duty with 40 % Less Glycol
District-energy networks running 50 % glycol at 8 °C now use microchannel fluid coils to transfer 500 kW of heating or cooling while cutting pump flow 40 %.
Kaltra’s design feeds water-glycol mixtures through flat aluminum multi-port tubes that contain up to ninety parallel channels 0.7 mm wide. The geometry pushes internal heat-transfer coefficients above 5 kW m⁻² K⁻¹ while … Read More
