MicroGroove™ technology uses small diameter copper tubes to make heat exchanger coils with high transfer coefficients, for use in high-efficiency commercial and residential air conditioning and refrigeration products.

MicroGroove tube heat exchangers are one key to reducing environmental impacts and lowering overall costs while increasing the energy efficiency of HVAC&R systems. Use of smaller tube diameters can reduce refrigerant charge allowing operation at the pressures and charges associated with natural, flammable and low-GWP refrigerants. This technology also enables compact designs with less material consumption and better thermal performance.
