DESCRIPTION

Daikin Packaged Rooftop Units are designed for fast and easy installation, making them ideal for both new construction and retrofit projects. These units are direct replacements for most rooftop units, eliminating the need for curb adapters and reducing installation time and costs. Constructed with high-quality galvanized steel and a powder-paint finish for corrosion resistance, the units feature tool-less filter access, full insulation to prevent thermal losses, and raised flanged edges for easy duct connections. The high-performance scroll compressors are factory-mounted for vibration isolation and come charged with environmentally friendly R32 refrigerant. The direct-drive supply fan ensures quiet and efficient operation, while the indoor coils are designed for enhanced dehumidification and high operating efficiency.

The DSC light commercial packaged Air Conditioner unit offers energy-efficient cooling performance in one self-contained unit. This unit is suitable for ground-level or rooftop installations and horizontal or downflow applications. The heavy-gauge, galvanized steel cabinet with UV-resistant powder-paint finish withstands all weather conditions and time.
