KAIDELI GUSD Double-Side Blow Unit Cooler – 6 mm Fin Spacing
Description
KAIDELI GUSD Series Double-Side Blow Unit Coolers
The KAIDELI GUSD series provides a 6 mm fin-spacing option for cold-room projects requiring ceiling-mounted, double-side air discharge and electric defrost.
The range includes nine models, from GUSD401B to GUSD454EC. Published capacities at SC1, SC2 and SC3 allow you to compare performance across different reference conditions. Choose the model around the application’s cooling load and room layout, then confirm the final selection for your refrigerant and temperatures.
Key Features
- Double-side airflow with ceiling mounting.
- 6 mm fin spacing.
- Electric coil and drain pan defrost.
- Copper tubes with aluminium fins.
- Hinged drain pan for maintenance access.
Applications
Consider the GUSD series for chilled or frozen storage projects where the selected operating conditions, moisture load and defrost strategy suit a 6 mm fin-spacing evaporator. Review air paths around shelving, stored products and work areas when planning the installation.
