Chapter 1 Product Overview
1.1 Introduction
The KC series air-cooled centralized condenser is a new generation of
high-efficiency energy-saving condenser independently designed and developed by
Kstar and has single-system type and dual-system type. The single-system KC
air-cooled centralized condenser is used to match the single-system indoor unit or
single refrigeration system of the dual-system indoor unit. The dual-system KC
air-cooled centralized condenser is used to match the dual-system indoor unit.
Features:
Modular design, field splicing, easy maintenance.
Small footprint with the same cooling capacity.
Single and double refrigerant circuits, suitable for various systems.
Enhanced heat transfer internal threaded tube, anti-corrosion fin coating
optional.
Marine grade corrosion-resistant aluminum, solid and beautiful.
High-quality low-noise three-phase axial flow fan with built-in thermal
protection.
Integral protective cover prevents damage to the copper tube of the heat
exchanger.
IP55 standard electrical control box available.
Stepless frequency conversion control of the fan.
