Shanli air dryer detail information

Product name: Heat Recovery System

Product model: SRPS-22ZR-O-N


● Heat recovery is a method of salvaging a portion of the energywasted by inefficient Heating, Venting, and Air Conditioning (HVAC) systems. 

● HVAC systems have a limited efficiencydue to the laws of thermodynamics and inherent inefficiencieswith real applications. 

● Energy that would be used for work isinstead dissipated in the form of heat. 

● Heat recovery units(HRUs) harness some of this energy and redirect it for a morepractical use. 

● HRUs are typically found in applications thatrequire both heating and cooling.

Technical Features

● Built into air compressor , customized and integrally formed;

● Precise control of the oil temperature between 82-88;

● Air outlet temperature below 50;

● Lubricant consumption save 20%;

● compactand easy to maintain;

● Avoid pipeline Oil leaking;

● Economicaland cost-effective.

Working Principle

● Thesystem can be applied to recycle most of refrigerator heat in an oil-free andwater-cool air compressor. 

● This recyclable part of refrigerator heat accountsfor 80%-95% of input shaft power. 

● If a MD air dryer is installed in the rear ofthe compressor, the recovery rate falls by approximately 9%-25%, the energy ofwhich is restored for the regeneration during drying process.

Company Information

Established in 1997, Hangzhou Shanli Purify Equipment Corporation is an enterprise specialized in design, development and production of compressed air dryers,

filters and other purification equipments. Our company has a workshop of 30, 000 square meters and more than 300 staff. Shanli has become one of the largest re

frigerated air dryer manufacturers in the Chinese purification industry with the top sales turnover. Our self-design and self-made equipment is compatible with many

famous brands of air compressor to efficiently remove water, oil and dustfrom compressed air. On basis of IS0 9001 certification standard, our design, production, t

est and services of the machine are all well managed and strictly controlled since year 2001.


1.Technical Force

   Technical research and development capabilities: 35 R & D personnel, including five senior engineers, 12

   engineers, 18 assistant engineers. (Innovation) Award Fund has set up, the company so far has 30 patents.

2.Strong Corporate Strength

  Established in1997, an area of 30,000M2, more than 300 employees

  Market share: No.1 in China

  2016 annual sales: 28 million US dollars

  Certificate ISO/ CE, production license

3.Automatic expansion valve and hot gas bypass valve replace capillary, which overcome the shortcomings of

  the capillary. It can also guarantee the stability of the refrigerant low pressure in the case of the large changes of

  the load can not only meet dew point performance at the high load conditions in summer but also guarantee

  normal operation under low load conditions in winter.

Product Applications

There are still some areas and applications where Shanli air dryers can be used, such as power construction, packing food, making ship, cleaning medical molding,removing EDM recast and discoloration, finishing and texturing injection mold cavities, cleaning orifices in turbine blades, engraving optical lenses,cleaning and preparation of semi-precious stones and jewelry, etc.
