Product description
Refrigerated compressed air dryer
1. Introduction
1.1. Purpose
The freeze type compressed air dryer is a post-treatment equipment of the air system in the pipe in pipe pneumatic ash conveying system, which is generally installed in the air
At the back of the gas compressor, qualified conveying air and instrument air are provided for the pneumatic ash conveying system in the pipe.
1.2. Structural features
The refrigeration compressor adopts the products of several international well-known companies, such as deinbiser, Taikang and bestu of the United States; all refrigeration control elements are products of Danfoss and Aike company of the United States; products of famous companies such as Schneider are used for electrical appliances; Japanese or German imported products are used for solenoid valve drainer; in addition, the equipment is equipped with anti blocking equipment for sewage discharge, so that the automatic drainer is not Easy to damage.
2. Specifications and performance
