High Temperature Aging Room
  1. DESCRIPTION & SPECIFICATION

HIGH TEMPERATURE AGING ROOM 

FUNCTIONAL FEATURES

Internal Test Chamber is designed and made of SUS#304 high-low temperature resistance stainless steel;

Insulation material is introduced frame retardant strength PU Polyurethane foam insulation material; 

Observation Window is designed and made with vacuum glass observation window on door, and door frame with electric heat resistant, anti-frosting, anti-condensing devices to enable test technician can observe testing specimen in testing in an easy way. 

Cable Port with its ¢50mm is designed on left of testing chamber, and processed with silicon filling and sealing as well as designed with stainless steel cover for safety purpose. 

Walk-in environmental test, to guarantee safety testing operation, is designed with Explosion-proof pressure releasing function with 1 ventilation hole on left or right side of test chamber for pressure releasing purpose. 

Sealing process for test chamber is introduced with silicone sealing strip to provide an excellent sealing performance. While push-in testing holder with good loading bear is made for internal environmental test. 

A close-type mechanical pressure balance & regulation device is introduced to balance difference between inside and outside of test chamber to protect testing chamber. 

4 arrays of explosion-proof and energy-save lamp is installed inside of test chamber for observation while steel base frame for test chamber with loading bear no less than 2000kg/m²

Air Supply System with constant air flow as well as uniform air distribution is driven by branded asynchronous motor, multi-blades centrifugal circulating blower as well as high-performance sensors. 

Refrigeration System is introduced with French Tecumseh compressor for dehumification while Germany Bitzer compressor for refrigeration system,while use environmental friendly refrigerant HFC R404A, R23A. 

Heating System is designed with SSR (Solid-State Relay) & controller to provide high accurate non-contact switch control, and the heating tube introduced with Naked Wire Nickel Chromium Alloy Electric Heating Tube. 

Control Method for walk-in Test Chamber is introduced with Programmable high accuracy micro computer controller, use cold mirror dew point instrument control temp. humidity system. cold mirror dew point instrument control temp. Humidity system.

P.I.D. ,BTC balance temperature control method(thermal compensation function)+DDC digital cold control +DEC digital electric control (Temperature change test program setting) .
