Third, structural material:
1,The outer cover adopts high-quality (ts =1.2mm) A3 stencil plate numerical control machine tooling is shaped, the surface of outer cover is gushed out and moulded dealing with, show even more bright and clean, esthetically.
2,The inner gallbladder, in order to import ( SUS304) Stainless steel board of high-quality surface of the mirror;
3,Warm-keeping CaiZhi: Glass fibre cotton of high density. The thickness is 100mm to keep warm;
4,Stir the system: Adopt the fan electrical machinery of the major axis, is able to bear many wing type impellers of stainless steel of the high low temperature, in order to reach the intensity convection to spread to circulate vertically;
5,Adopting the double layers high temperature resistant pieces of sex sealing strip high between the door and body of case is airtight in the testing area in order to guarantee;
6,Not having the reaction door handle to adopt, operation is easier;
7,The machine bottom adopts the high-quality very fixed type PU movable wheel;
8,The viewing panel adopts the multi-layer hollow safety glass, the conductive membrane (can clear that observe the process of the test) of inboard veneer a formula ;
9,Test the hole (the left side of the machine) Can connect testing the cable or signal line uses (aperture or hole is counted and must be increased and needed to point out) ;

Fourth, control system:
1,Adopt (South Korea) Import high precision and count and show the warm humidity controller completely, P.I.D high-accuracy control, stop to operate the unstable phenomenon for a long time;
2,The humidity is controlled for animation, the defect of abandoning the original warm humidity and contrasting;
3,Precision: ¡À is 0.1 ¡æ(reveal the range) ;
4,Analyze degree: ¡À is 0.1 ¡æ;
5,Temperature sensing sensor: Tester of PT100 platinum resistance;
6,Control method: Temperature adjustment way of the thermal balance;
7,The electric apparatus is controlled: The electric apparatus controls the main part to adopt and import " Snide " And " the plum is blue on blue day " The component, control the temperature better;

Fifth, heat the system:
1,Adopt the alloy of far infrared nickel to heat the electric heater at a high speed;
2,The high-temperature low temperature is damp and hot and totally systematic independently;
3,The warm humidity controls output power to make mathematical calculations by the microcomputer, in order to reach the high-accuracy and high-efficiency power consuming benefit;

Sixth, moisten the system:
1,The putting boiler steam type humidifier has energy-saving and cost-reducing functions outside, can save 70% of the energy consumption;
2,Automatic compensation, lack of water of many ways of water levels call the police and protect the system;
3,The far infrared stainless steel heats the titanium alloy heater at a high speed;
4,The humidity controls and adopts P.I.D + S.S.R, system and channel control in coordination;
Seventh, apparatus service condition:
1,Ambient temperature: 5 ¡æ- + 28 ¡æ(average at or below 28 ¡æ in 24 hours) ;
2,Environmental humidity: Less than or equal to 85%;
3,Can't put the things while putting each 80 centimeters all around with machine;

Eighth, protect the system:
1,Whole the intersection of apparatus and ultra warm whole apparatus owe looks / phase of going against;
2,The systematic overload of refrigerating, system of refrigerating exceed pigeonholing, whole apparatus timing;
3,Leak electricity, lack water, instruction of running still while being other, shut down etc. and protect automatically after the fault alarm;

Ninth, system of refrigerating:
1,Compressor: Totally closed French safe health compressor;
2,The way of refrigerating: The single mechanism is cold;
3,Condense the way: Force air-cooled cooling;
4,Refrigerant: R404A R23 (environmental protection type) ;
5,The whole the intersection of system and pipeline make, keep in touch with, pressurize 48H stops leakage in the roof to test;
6,Heat, the system of lowering the temperature is totally independent;
7,Spiral cold matchmaker copper is managed inside;
8,One scene of slope type evaporimeters of wing;
9,U.S.A. " Ai Gao " Dry filter;
10," it is inferior to preceded " in Taiwan Oil separator;
11,Italy " The card person is proper " Electromagnetic valve;

Tenth, carry out the standard: Consult relevant standards such as GB/T5170.5-2008, GB/T10586-2006, GB/T2423.3-2006, GB/T2423.1-2008,etc. and design making strictly;
Deliver goods to the customers free, to this rigging up and debugging, do corresponding basic operation to train to the relevant technical staff free at user's scene, there are no limitations on the number of people.
