Ammonia chiller with built-in evaporative condenser and evaporation through semi-welded exchangers flooded by gravity or direct expansion. Complies with EU F-Gas regulations. With a minimal footprint, this unique design offers the highest performance available with unprecedented energy efficiency. The chiller incorporates NCX evaporative condensers (with polyester casing and EC fans), power and control through an industrial PLC, and everything necessary for its operation. The unit is delivered pre-assembled for outdoor installation, reducing welding work to a minimum and avoiding benches for condensers and vessels. Offering a competitive, rapid return on investment in and great flexibility, this compact chiller plant is the new benchmark for refrigeration, cooling process, and industrial air conditioning.
