Kangning currently supply Ex HVAC to renowned companies in analyzer
house market and have a remarkable reputation. BHVAC Explosion-proof Heating Ventilation Air Conditioning Unit The BHVAC units are designed to provide cooling, heating,
pressurization, fresh air purging in one assembly. They are
typically furnished for instrument control room, laboratory,
measuring room, analyzer shelter etc in hazardous locations. These
units are applied for the places, where is classified as Zone 1 or
Zone 2 (Division 1 or 2), contained GroupⅡA, GroupⅡB, GroupⅡC,
temperature group T1～T3, the explosive mixture of the flammable gas
or vapor and the air together. The units are engineered and proven
to stand up to rigor and harsh conditions. Exmarking： | | 0470 | | Ⅱ2G Ex deib IIC T3 | | Ⅱ2G c |
FEATURES Third party certificated by Nemko AS, EU notified body, BHVAC units
and major components comply with ATEX codes.（Certificate No.: Nemko
10ATEX1006X）
Each BHVAC unit is designed and manufactured to meet particular
customer’s climate and operating conditions, can achieve
thermostatic control function of cooling and heating, positive
pressure ventilation, fresh air purging, air filter and so on.
Vertical package, thoughtful and humane design facilitates
transport, installation, operation, maintenance.
Explosion protection technique adopt flameproof enclosure type as
main explosion-protected method, combine flameproof enclosure type,
intrinsic safety type, increased safety type to composite
explosion-protected equipment, BHVAC units are designed and
manufactured rigorous comply with relevant ATEX standards.
Complete protection functions ensure BHVAC units safe, reliable
operation.
Multi faults alarm functions ensure used place safety and BHVAC
units easy to repairs.
BHVAC units are built from strong cabinet material and robust
parts, painted galvanized steel cabinet, dual supply fans (one
working another standby) auto-changeover, all of them in order to
ensure the units infallible service all the year round.
Supply fans and condense fan are designed in spark proof
construction and materials, motors adopt flameproof enclosure for
explosion protection.
Copper tube/aluminum fin coils with mechanically bonded plate fins
for maximum heat transfer.
Explosion proof electric heater adopt low watt density stainless
steel finned electric heater tubes with dual over heat protection,
electric connection parts adopt flameproof enclosure for explosion
protection.
Dehumidifying, pre-conditioning and filtrating the pressurization
fresh air before it enters building.
Whole-process quality control, strict monitor of every procedure. OPTIONS Stainless steel (304 or 316) cabinet to resist corrosion
Copper tube copper finned coils, corrosion protection coating coils
Stream heating coils
When the outdoor air combustible or toxic gas alarm system is
installed, may elect to install pneumatic actuator or a quick
explosion-proof electric actuator (0.5~20s)
