1. Rooftop packageunit introduction

1.1 Modules Range

4 models: Cooling & Heating: 20 TR, 25TR;

Cooling only: 20 TR, 25TR

20TR, 25TR

1.2 Adopt high reliable Copland compressor

Better Liquid Handling

Radial compliance allows the scroll members to separate in the presence of liquid refrigerant,

thus, providing protection against liquid damage.

Greater Efficiency

With axial compliance, optimized force between two scrolls can be obtained, leading to high

efficiency over the entire operating range.

Word famous scroll compressor with quick reactivity and operation stable. Compressor staging is

controlled directly by the control temperature ,high EER.

1.3 New air inlet is available.

1.4 Provide easy access to system components for maintenance and service.

1.5 Flexible installation, on rooftop or ground are available. Anywhere removable as requirement with

fixed.
