H.Stars Explosion-proof Chiller

Functionsand featuresof explosion-proof chiller

Asa kind of special air-conditioning equipment,explosionproof equipment and its components are manufactured in strict accordance with relevant requirements of GB3836, anational explosion-proof standard,and explosion-proof certificateshallbeobtained forit.Itcanbeused inspecial places of high explosionor fire risk,as well as in ordinary circumstances.It is widely used in various industries, including petroleum,chemical,textile,printing，medicine, and food industries.Flameproof or positive pressure type ofexplosion proof equipment can be chosen based on the characteristics of the project.Our Explosion proof equipment have two explosion proof levels,Exd IIBT4and Exd IIC T4;other explosion level is also available according to user requirements.

Explosion proof certificates

Explosion-proof compressors

Explosion-proof compressors are produced in accordance with the national standard GB3836, have the explosion proof symbol of Exdib mb IIBT4Gb or Exde mb II BT4Gb,have passed the national inspection,and have obtained explosion proof certificates.Itsmainapplication isin Zones1and2in the petroleum,chemical industry,metallurgy,pharmaceutical and national defense industries,where explosive gas mixture exists in the air.

Explosion-proof electrical cabinet

Explosion proof mark:Exd ib IIBT4 Gb

The electrical cabinets come in flameproof and positive pressure types;with theircasemadeof steel plates,they are strongand durable;and theyalso have an NWN entry system.

Flameprooftype:itisusedinexplosivemixtureinvadesinto thecabinet and explodes due to some reason,it will not cause explosion of the explosive mixture outside the cabinet. Positive pressure type:Positive pressure ventilated explosion proof electrical cabinet achieves explosion prevention by usingpropermedium to isolate ignitionsource.

Explosion-proof fan

Theyare produced in accordance with the national standard GB3836,have the explosion proof symbol of Exd Il CT4Gb bypassed national inspection,and have obtained explosion proof certificates.

Relevant standards of explosion proof

Equipment is in strict compliance with national standards:

GB3836.1-2010:Explosive atmospheres-Part 1： Equipment-General requirements.

This Part specifies general structure,testing and label requirements for electrical equipment and Excomponents forapplication in explosiveatmospheres.

Suitableforuseunderstandardatmosphereconditionsin thefollowingdangerousplaceswhereexplosiveenvironment exists:

Temperature:-20℃ ~ + 6 0 ^ { \circ } { \mathsf C }

Pressure:80kPa\~110kPa;

Standard oxygen content (volume ratio): 2 1 % #

Specialconsiderationsshallbe takenforelectrical equipment to beused beyond the atmosphere conditions mentionedabove.

Itisrecommendabletoconsider thesituationcombinedof explosivegasatmosphereandcombustibledustatmosphere andtakeadditional precautions.

Ignitionsourcesnotconsidered inthisPartinclude:adiabatic compression,shockwave,exothermicchemicalreaction, spontaneous combustion of dust,open flames,and hot gas/ liquid.

Electrical equipment is classified into three types:Type l, Type Il,andType Ill.

Type丨 electrical equipment isused in places where coal seam gas exists.

Type ll electrical equipment isused in placeswhere there is explosive gasother than coal seam gas.

Type Ill electrical equipment is used in explosive dust atmospheresother thancoal mines.
