Brand new roof explosion-proof air conditionerIn high-risk industrial scenarios such as petrochemicals, hazardous chemical storage, and spraying operations, the complexity and danger of the environment impose strict requirements on the safety and performance of temperature control equipment. Roof integrated explosion-proof air conditioner BLF-28, deeply focusing on pain points in hazardous environments, toFull dimensional safety protection, temperature control efficiency, and long-lasting durable designBuild a "temperature control defense line" for safe production in high-risk scenarios.
For Class IIA, IIB, IIC T1-T4 flammable gas/steam explosion environments (such as oil and gas in petrochemical workshops and solvent vapors in paint factories), BLF-28 adoptsInherent safety circuit designThe selection of circuit components strictly limits the energy parameters, and even if there is a fault, it will not generate enough electric sparks to ignite explosive mixtures;Optimization of Explosion proof Mechanical StructureThe moving parts such as fans and compressors are treated with shock-absorbing sealing to avoid friction sparks, and the gaps and interfaces of the shell are designed with explosion-proof joint surfaces to prevent the spread of explosive flames. Every detail is cutting off the chain reaction of the explosion.
The equipment has been certified by the National Explosion proof Electrical Product Quality Supervision and Inspection Center, and the "Ex" mark is not only a symbol, but also a guarantee of adaptability to explosive hazardous environments. From component procurement to complete machine delivery, it has gone through a process ofExplosion proof performance full process testingSimulate the impact and high temperature testing of explosive environments to verify the safety of equipment under hazardous conditions, allowing enterprises to apply it safely in core high-risk scenarios such as petroleum refining and natural gas storage.
Refrigeration: 28000W strong cooling capacityFacing the high temperature of 40 ℃+in the petrochemical workshop in summer, the refrigeration system of BLF-28 adoptsEfficient Vortex CompressorCombined with a large-diameter finned condenser, it quickly absorbs indoor heat. Taking a 1000 ㎡ hazardous chemical warehouse as an example, the temperature can be reduced from 38 ℃ to 26 ℃ within 30 minutes, and through intelligent temperature control algorithms, the temperature fluctuation can be accurately maintained at ≤± 1 ℃ to avoid sudden temperature changes affecting the stability of hazardous chemical storage.

Heating: 22000W stable heating capacityIn the low-temperature environment of industrial plants in the northern winter, equipment is installedPTC auxiliary heating module(Low temperature self starting), coordinated with the compressor for heating. -Under an environment of 10 ℃, stable heat output can still be achieved. Within 2 hours, the temperature of the 2000 ㎡ spraying workshop can be raised from 5 ℃ to 18 ℃, ensuring the flexibility of winter operators and avoiding equipment operation errors caused by low temperatures.
High air volume is not simply a matter of parameter stacking, but a precise design for hazardous environments with "large spaces and multiple blind spots":
Optimization of airflow organizationThrough an integrated roof layout, the air conditioning vents are formedThree-dimensional circulating airflowIn a 15m high petrochemical plant, the stratification problem of hot air rising and cold air sinking can be overcome, achieving a temperature difference of ≤ 3 ℃ between the upper and lower layers, covering the entire workshop with heating and cooling effects, and avoiding safety hazards caused by local temperature anomalies (such as high temperatures in hazardous chemical storage areas).
Improved ventilation efficiencyCombined with the workshop ventilation system, a 2200m ³/h air volume can accelerate the discharge of harmful gases (such as VOCs in the spraying workshop), reduce the concentration of explosive mixed gases, indirectly improve environmental safety, and become a dual guarantee of "temperature control+ventilation" for hazardous environments.
Altitude ≤ 2000mCovering most of China's industrial production areas (such as the Yangtze River Delta, Pearl River Delta industrial parks, and central and western energy bases), throughPlateau adaptive algorithmThe compressor power and fan speed can be automatically adjusted to ensure stable operation in the the Yunnan-Guizhou Plateau Petrochemical Plant, solving the problem of cooling and heating attenuation caused by "plateau hypoxia" of ordinary air conditioners.
5 ℃ -38 ℃ wide temperature operationRegardless of the humid and hot summer environment in the south (38 ℃+high humidity environment) or the temperature difference between day and night in spring and autumn in the north (fluctuating from 5 ℃ -30 ℃), the device is built-inDual temperature and humidity sensorsReal time linkage of refrigeration/heating and dehumidification modules, in humidity sensitive scenarios such as paint warehouses (humidity>60% can easily cause paint condensation and deterioration), automatic dehumidification and temperature control are implemented to ensure material storage quality.
Advantages of integrated roof designSpecially designed for hazardous environments with "tight space and complex indoor layout" - directly installed on the roof, without occupying valuable operating space in the workshop, and avoiding the difficulty of laying explosion-proof pipelines caused by indoor installation. Taking a 1000 square meter hazardous chemical warehouse as an example, compared to traditional split type explosion-proof air conditioners, the installation period is shortened by 50%, and later operation and maintenance (such as filter replacement and compressor maintenance) can be independently completed on the roof, without interfering with indoor production and reducing safety risks during operation and maintenance.
Durability guaranteeThe shell adopts304 stainless steel+spray coating dual protectionIt can withstand industrial dust and acid alkali corrosion (such as acid alkali mist in chemical workshops), and can withstand salt spray testing for more than 3000 hours in outdoor environments on rooftops, which is equivalent to twice the lifespan of ordinary air conditioners. The internal core components (compressor, fan) are selected from international platforms, and through100000 start stop testsIn the scenario of high-frequency switching (10+times per day) in the spraying workshop, it can still operate stably for more than 5 years, significantly reducing equipment replacement costs.
Explosion and fire accidents caused by temperature control failure are frequent in the petrochemical and hazardous chemical industries. BLF-28 passedFull scene explosion-proof adaptation+precise temperature controlHelping businesses:
To avoid the chain risk of "abnormal temperature → material deterioration → leakage and explosion", such as in natural gas storage areas, stabilize the environment at 25 ℃± 1 ℃ to prevent natural gas from expanding and leaking due to high temperature;
Meet standards such as GB 50058 "Code for Design of Electrical Installations in Explosive Hazardous Environments", and assist enterprises in passing safety qualification audits, shifting from "passive compliance" to "active safety upgrades".
energy consumption optimization: AdoptingVariable frequency energy-saving technologyAutomatically adjust the compressor frequency based on environmental temperature and humidity, saving more than 30% energy compared to fixed frequency explosion-proof air conditioners. Taking a medium-sized petrochemical workshop (operating 12 hours a day) as an example, the annual electricity cost savings can reach 20000 to 30000 yuan.
Cost reduction in operation and maintenanceLong term and durable design+modular operation and maintenance (such as quick replacement of filter elements and sensors), the annual operation and maintenance cost of the equipment is only 60% of that of traditional explosion-proof air conditioners, and the 5-year full cycle cost is reduced by 40%, continuously reducing production costs for enterprises.
