Product Description
The Achelous AVX-B is a high-efficiency, inverter-driven (VFD) air-cooled screw chiller offering cooling capacities from 115 to 470 RT (406 to 1,656 kW). Cooltech Corporation supplies and installs the AVX-B Series across Bangladesh for industrial, commercial, and institutional projects requiring large-scale reliable cooling.
The Variable Frequency Drive (VFD) compressor delivers exceptional part-load performance, reducing energy consumption by up to 30% compared to fixed-speed equivalents during the many hours of partial-load operation typical in Bangladesh's climate. The flooded shell-and-tube evaporator ensures maximum heat transfer efficiency and operational stability across variable load conditions.
The unique low-noise control design makes the AVX-B suitable for noise-sensitive installations such as hospitals, hotels, and residential developments. AHRI certification and green refrigerant compatibility confirm the system's environmental credentials and compliance with international energy standards.
