The MASTERKIT REFRIGERATION ET evaporator is optimized for rapid freezing, with 15 mm grooved copper tubes for high efficiency and embossed aluminum fins for superior heat transfer. Its large heat exchange surface is ideal for environments prone to frost formation. It incorporates a venturi distributor for uniform refrigerant distribution and a floating coil with aluminum guard plates to reduce wear and leaks. The fin spacing is designed to be 10 or 12 mm, adapted to the specific needs of rapid freezing.
