次 View times: 35508 times

Equipment details

     Explosion-proof chillers are special equipment, often used in chemical industry and special places such as flammable and explosive, which can ensure the safe and stable operation of the unit. For the explosion-proof chiller using screw refrigeration compressor, we call it explosion-proof screw chiller. It has a wide range of refrigeration and can be customized according to customer requirements. Each component of the explosion-proof chiller is manufactured in accordance with national explosion-proof standards. The explosion-proof and anti-corrosion master controller is based on GB3836.1-2000 "General requirements for electrical equipment for explosive gas environments" and GB3836.2-2000 "Explosion-proof type for electrical equipment for explosive gas environments. "D" "and GB3836. 3-2000" Enhanced Safety Type "e" for Electrical Equipment for Explosive Gas Atmosphere "are designed and manufactured to meet the special requirements of customers.
Configuration and characteristics of explosion-proof screw chiller
1.Compressor
Selected new original high-efficiency screw rotary compressors (the most advanced 5: 6 patented asymmetric rotor tooth profile) imported from BITZER (HANZELL) and HANBELL (Taiwan Hanbell), which are 20% more efficient than general compressors -30%, using finned coil type air exchanger (without cooling water system), supporting condensers made of high-quality and high-efficiency copper tubes and world-renowned brand components, so that the unit has a small size, low noise, large energy and long life Long, easy to operate, and other advantages, its beautiful and exquisite shape design and reliable and stable high-performance quality are outstanding among similar products!
2.Evaporator
The evaporator copper tube adopts internal and external screw type reinforced tube. The surface of the copper pipe is threaded, the outer surface of the copper pipe is smooth, and the cooling effect is good. The evaporator body is insulated by a 25mm thick PE insulation board without condensation, and the cooling loss is small. The air-cooled screw chiller uses a shell and tube evaporator, which was designed and produced by Simpson Refrigeration.
3.Condenser
The condenser uses copper pipes imported from abroad and is processed into trapezoidal low-rib tubes to enhance heat transfer capacity. The surface of the copper pipes is smooth, which reduces water pressure and is easy to clean and maintain. It uses a fan to dissipate heat, so it uses a finned condenser, which is also designed and produced by Simpson Refrigeration.
4.Protection device
The protection device is to ensure that when the chiller fails, it can be started as soon as possible and protect the unit from secondary damage. Its protection devices mainly include: compressor delay start protector, overload protector, high and low voltage protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, and compressor frequent startup Protectors and abnormal indicators ensure the normal operation of the unit.
5.Control system
The AC contactors and electrical accessories are selected genuine products from Omron and South Korean LG brands. The control panel is selected from the American Bangpu brand (microcomputer Chinese digital display). It can be remotely monitored and controlled according to user needs. Multiple functions such as automatic loading and unloading, timing on / off, and recording of the cause of the fault; simple operation, the host and the power supply are connected. Low failure rate, high safety factor, simple installation, system control can be adjusted instantly, intuitively and reliably.
6.Frozen accessories
All of the refrigeration accessories are selected from the world's top brands SPORLAN (USA, Poland), ALCO (USA), DANFOSS (Danfoss, Denmark), etc., with excellent performance, safety and environmental protection.
