Now available for use with R-134a, R-404A, R-407A, R-407C, R-407F, and R-507A refrigerants, the ECOLINE reciprocating compressor series is 3-10 percent more efficient than its predecessor, as the pressure drop has been lowered by a redesign of the valve plates and cylinder heads as well as pistons and rods, said the company. The virtually stepless capacity control (CRII) enables capacity control from 10-100 percent. The new models are also designed for variable-frequency drive (VFD) operation from 30-70 Hz (2-cylinder) and 25-70 Hz (4-cylinder). The ECOLINE Series ranges from 0.5-50 hp. The line includes three specially adapted, high-efficiency motor options — one is designed for high-temp applications, the second is for some refrigeration applications, and the third version is intended for supermarket R-134a applications. The series is backward compatible with the previous generation, as the mounting holes and service valves match up for easy installation.
